... Its black shiny hard yet flexible surface is slightly rippled and textured. ...Its black shiny hard yet flexible surface is slightly rippled and textured. ...A baleen whale has hard bristly baleen that hangs from its upper jaw inside its mouth instead of teeth. Baleen is made from a protein called keratin, just like human hair and fingernails, and its colour can vary between species, from black to yellow or white. The whale uses the tough, flexible baleen like a sieve to catch its food, filtering the small sea creatures out of the sea water it releases from its mouth. In the19th Century, whales were hunted for the products that could be made from their bodies, such as oil for lubricating machinery, soap making, lamps, heaters and fuel for the lighthouse lights. The flexible baleen was used for whip handles, carriage springs and umbrella ribs. It was also used for the skirt hoops, hat ribs, and rigid ‘stays’ in tightly fitting bodices to enhance their figures. The Southern Right Whales, as well as Blue Whales and Humpback Whales, are baleen whales. The Southern Rights annually visit the ocean off the southwest coast during the breeding season. In the early 1800s whalers hunted along this coastline in their dangerous pursuit of money for the precious cargoes of whale oil and bones. The population of these large animals dwindled quickly and by the late 1840s the whaling industry dwindled. Whaling recommenced from the 1940s to the 1980s when the whale products were used to make margarine and dog food. The baleen sample has been used to educate people about whaling and about the properties of baleen. The baleen sample is significant for its association with 19th century women's fashion. It helps to understand how garments were supported to shape a woman's figure. The baleen sample represents a period when whales were hunted and killed to provide income and products for for the local settlers and for the export industry.Baleen sample from a whale's jaw.

... As quoted from Wikipedia, ‘An anvil is a block with a hard surface on which another object is, struck. ...As quoted from Wikipedia, ‘An anvil is a block with a hard surface on which another object is, struck. ...As quoted from Wikipedia, ‘An anvil is a block with a hard surface on which another object is, struck. The block is as massive as it is practical, because the higher the inertia of the anvil, the more efficiently it causes the energy of the striking tool to be transferred to the work piece’. The lightstation’s anvil is a red-painted iron block with a conical beak or horn at one end that was used for hammering curved pieces of metal. It would have stood on a heavy free-standing pedestal, such as a large tree stump, to allow complete access to the item being hammered. Some anvils display the manufacturer’s name in the metal on the side, but this is not the case here, and its age, although unknown appears to be quite old, perhaps c.1900. It appears to have had a lot of use, and although no record of this survives, it is presumed that a forge operated on site for hammering, cutting, shaping and repairing tools such as bolts, nails, hooks, chain segments, pulley blocks, hinges, crow bars, picks, chisels, horseshoes and harness hardware. A hames hook (which forms part of the collar worn by a draught horse) survives at the lightstation as do many other heavy metal tools and pieces of equipment. The anvil is an example of the necessary resourcefulness and self sufficiency practiced by lightkeepers working and living in a remotely located workplace and home, and many of the iron items in the collection may have been repaired or even made on its working surface. As a lightstation manager Chris Richter used the anvil to manufacture pulley blocks for sash windows, repair brass door hinges & sharpen cold chisels, crowbars and picks and other lightkeepers have used this anvil for many fabricating jobs such as manufacturing ducting for the generator room ventilation system."The lightship only came in every three months with supplies and there would have been repairs to do between visits from a blacksmith - who would have had to travel on the ship. Also, the ship was only anchored in the bay long enough to unload supplies and collect and deliver lightkeeping staff – probably not enough time to get much smithy work done – especially if the weather packed it in and the ship had to depart. Lightkeepers in our time had to be self sufficient, resourceful and innovative and I imagine that would have been the case in the past." It has second level contributory significance.Red painted blacksmith's anvil. -

It firmly holds hot iron while it is hammered, chiseled, or twisted. These are the only vises that are designed to take this kind of use day in and day out. A small 30-pound blacksmith's vise can survive pounding that would wreck a much heavier cast iron bench model. Three things make a blacksmith's vice special. One is that they are forgings, not cast iron or ductile iron. The second is the leg that provides support to the floor or from a sunken post. The last is the hinge, while not a perfect way to construct a vice the pin joint is durable and can take a considerable beating. If sheared it is easy to replace. These things all combine into a tool that can take decades of heavy use and abuse. Most in use is one to two hundred years old.Some of these vises were made by specialists such as Atwood of Stourbridge England, Steel City and Columbian in the U.S. and others were made in anvil manufacturing plants such as "Mousehole Forge" and "Peter Wright" in England and "Fisher-Norris" and others in North America. The design of these vises right down to the last chamfer seems to have been perfected in the 1600s and remained more or less the same until the 20th century. The bodies are forged wrought iron or mild steel and they have hard steel surfaces welded into the jaws. The jaws have little or very shallow serrations which are generally worn off.Around the turn of the 20th Century during the hey-day of the blacksmith shop in North America, these tools were considered so standard a commodity that they were sold without reference to the manufacturer. Very few were even marked with the maker's name. Size is best defined by weight as there is some variation in jaw size from manufacturer to manufacturer. They were sold by the pound and are still best judged by the pound.A vintage tool used in a Blacksmiths shop during the early 19th century to the beginning of the 20th century.

... Rather than their decorative patterns being glazed onto the surface of the tile, their inlaid designs were created during the manufacturing process, as “coloured slips” (or liquid clay) were poured into a deep pre-molded casting. When fired, the resulting tile was colours-fast and design-fast. The Minton floor tile is significant for its hard ...This Minton floor tile is from the wreck of the Loch Ard and is currently on display in the Great Circle Gallery at Flagstaff Hill. The iron hulled clipper ship from the Loch Line was heading for Port Phillip from London, when it ran into the cliffs of Mutton Bird Island near Port Campbell. The Loch Ard was laden with a high value cargo including luxury goods intended for display at the Melbourne International Exhibition in 1880. One notable survivor from the ship’s freight manifest was the well packed Minton porcelain peacock, a two meter high ceramic masterpiece of vivid glazed colours. (This is also on display in the Great Circle Gallery). The almost total loss of life and property from the Loch Ard registered as a shocking tragedy for the Colony of Victoria, at a time when social confidence and economic optimism were otherwise high. Wealth generated from Gold and Wool was increasingly being spent on grandiose private residences and imposing public buildings. The demand for quality furnishings and fittings was therefore strong. Among the products consigned to burgeoning colonial markets by the Milton pottery at Stoke upon Trent, were their new range of colourfully patterned but very durable floor tiles ideal for the high-traffic spaces in the large civic buildings then being constructed in Australia and America. These new floor tiles were “encaustic”, meaning that their designs and colours were encased “within” the depth of the tile. Rather than their decorative patterns being glazed onto the surface of the tile, their inlaid designs were created during the manufacturing process, as “coloured slips” (or liquid clay) were poured into a deep pre-molded casting. When fired, the resulting tile was colours-fast and design-fast. The Minton floor tile is significant for its hard-wearing yet attractive design. The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulations of artefacts from this notable Victorian shipwreck of which the subject items are a small part. The collections of objects give us a snapshot of how we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time. Through is associated with the worst and best-known shipwreck in Victoria's history. A square Minton floor tile with a dark brown, beige and white pattern.

Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. ...The Process of Making Pottery Decorating, Firing, Glazing, Making, Technical There is a rhythm and flow to clay. It can’t be done all at once! Even the making process! It can take weeks to get everything done, especially if you can only work on your pottery once a week! Even though we have three hour classes, it’s often just not enough time! Here is an overview of some of the processes so you have a bit more grasp on some of the technical stuff! Step One – Design There are SO many ideas out there for making stuff in clay! From delicate porcelain jewellery, through to heavy sculptural work and everything in between. Deciding your direction is sometimes not that easy – when you first start, try everything, you will naturally gravitate to the style that you enjoy! The options and variations are endless and can get a wee bit overwhelming too! Check in with me before you start to ensure your ideas will work, what order you might do things, how you could achieve the look you are seeking and any other technical data required! Step Two – Making Clay is thixotropic. This means that as you work with it, the clay first gets sloppier and wetter, before is begins to dry in the atmosphere. For most things, you simply can’t do all parts of the project at once. An example of work order might look like: Get last weeks work out from the shelves Prepare clay for today’s work – roll your clay, prepare balls for throwing, make the first stage of a pinch pot) Clean up last week’s work and put it on the shelf for bisque firing Check that you have any glazing to do – and do enough of it that you will have time to finish your main project Do the next step of your next project – there might be a further step that can’t be complete immediately, in that case, wrap your work well and put onto the shelves. Letting your work rest for a while can really help keep your work clean and professional looking. Many things require bagging under plastic to keep it ready for work the next week – put your name on the outside of the bag so you can find your work easily. We have stickers and markers. Consider how you want to decorate your work – coloured slip can be applied at a fairly wet stage (remembering that it will make your work even wetter!). Trying to apply slip to dry clay won’t work! If you want to do sgraffito – you will need to keep the work leather hard (a state of dryness where you can still work the clay with a little effort and a little water and care). Step Three – Drying Most of the time your work can go into the rack uncovered to let it dry out for the following week. If you want to continue forming or shaping you will need to double bag your work – put your work on a suitable sized bat and put the bat in a bag so the base of the bag is under the bat, then put another bag over the top of the work and tuck the top of the bag under the bat. If you want to trim (or turn) your thrown work the following week, it should also be double bagged. If your work is large, delicate, or of uneven thicknesses, you should lightly cover your work for drying. When considering the drying process, bare in mind the weather, humidity and wind! The hotter and dryer, the faster things dry and work can dry unevenly in the shelves – this can lead to cracking – another time to lightly cover your work for drying. Step Four – Trimming and Cleaning Up Your work is dry! It is called greenware now and it is at it’s most fragile! Handle everything with two hands. I often refer to soft hands – keep everything gentle and with your fingers spread as much as possible. Try to not pick up things like plates too much, and always with both hands! Before your work can be bisque fired it should be “cleaned up”. You work won’t go into the kiln if it has sharp edges – when glazed, sharp edges turn into razor blades! Use a piece of fly wire to rub the work all over – this will scratch a little so be light handed. Use a knife or metal kidney to scrape any areas that require a bit more dynamic treatment than the fly wire offers! Finally, a very light wipe over with a slightly damp sponge can help soften and soothe all of your edges and dags! Trimming thrown work: If you are planning to trim (or turn) your thrown work (and you should be), make sure you bag it well – your work should be leather hard to almost dry for easiest trimming. Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. Wipe the sponge around the rim after trimming, and check the inside of the pot for dags! Trimming slip cast work: Usually I will trim the rims of your work on the wheel the following day to make that stage easier, however you will still need to check your work for lumps and bumps. Last but not least – check that your name is still clearly on the bottom of your work. Step Five – Bisque Firing When the work is completely dry it can go into the bisque kiln. The bisque kiln is fired to 1000°C. This process burns off the water in the clay as well as some of the chemically bound water. The structure of the clay is not altered that much at this temperature. Inside the bisque kiln, the work is stacked a little, small bowl inside a larger bowl and onto a heavy plate. Smaller items like decorations or drink coasters might get stacked several high. Consideration is paid to the weight of the stack and shape of the work. A bisque kiln can fire about one and a half times the amount of work that the glaze kiln can fire. The firing takes about 10 hours to complete the cycle and about two days to cool down. Once it has been emptied the work is placed in the glaze room ready for you to decorate! Step Six – Glazing Decorating your work with colour can be a lot of fun – and time consuming! There are three main options for surface treatment at this stage: Oxide Washes Underglazes Glazes Washes and underglazes do not “glaze” the work – It will still need a layer of glaze to fully seal the clay (washes don’t need glaze on surfaces not designed for food or liquid as they can gloss up a little on their own). Underglazes are stable colourants that turn out pretty much how they look in the jar. They can be mixed with each other to form other colours and can be used like water colours to paint onto your work. Mostly they should have a clear glaze on top to seal them. Oxides are a different species – the pink oxide (cobalt) wash turns out bright blue for instance. They don’t always need a glaze on top, and some glazes can change the colour of the wash! The glazes need no other “glaze” on top! Be careful of unknown glaze interactions – you can put any combination of glaze in a bowl or on a plate, but only a single glaze on the outside of any vertical surface! Glazes are a chemical reaction under heat. We don’t know the exact chemicals in the Mayco glazes we use. I can guess by the way they interact with each other, however, on the whole, you need to test every idea you have, and not run the test on a vertical surface! Simply put, glaze is a layer of glass like substance that bonds with the clay underneath. Clay is made of silica, alumina and water. Glaze is made of mostly silica. Silica has a melting point of 1700°C and we fire to 1240°C. The silica requires a “flux” to help it melt at the lower temperature. Fluxes can be all sorts of chemicals – a common one is calcium – calcium has a melting point of 2500°C, however, together they both melt at a much lower temperature! Colourants are metal oxides like cobalt (blue), chrome (green through black), copper (green, blue, even red!), manganese (black, purple and pink) iron (red brown), etc. Different chemicals in the glaze can have dramatic effects. for example, barium carbonate (which we don’t use) turns manganese bright pink! Other elements can turn manganese dioxide brown, blue, purple and reddish brown. Manganese dioxide is a flux in and of itself as well. So, glazes that get their black and purple colours, often interact with other glazes and RUN! Our mirror black is a good example – it mixes really well with many glazes because it fluxes them – causes them to melt faster. It will also bring out many beautiful colours in the glazes because it’s black colouring most definitely comes from manganese dioxide! Glaze chemistry is a whole subject on it’s own! We use commercial Mayco glazes on purpose – for their huge range of colour possibilities, stability, cool interactions, artistic freedom with the ability to easily brush the glazes on and ease of use. We currently have almost 50 glazes on hand! A major project is to test the interactions of all glazes with each other. That is 2,500 test tiles!!!! I’m going to make the wall behind the wheels the feature wall of pretty colours! Step Seven – Glaze (Gloss or sometimes called “Glost”) Firing Most of the time this is the final stage of making your creation (but not always!) The glaze kiln goes to 1240°C. This is called cone 6, or midrange. It is the low end of stoneware temperatures. Stoneware clays and glazes are typically fired at cone 8 – 10, that is 1260 – 1290°C. The energy requirement to go from 1240°C to 1280°C is almost a 30% more! Our clay is formulated to vitrify (mature, turn “glass-like”) at 1240°, as are our glazes. A glaze kiln take around 12 hours to reach temperature and two to three days to cool down. Sometimes a third firing process is required – this is for decoration that is added to work after the glaze firing. For example – adding precious metals and lustres. this firing temperature is usually around 600 – 800°C depending upon the techniques being used. There are many students interested in gold and silver trims – we will be doing this third type of firing soon! After firing your work will be in the student finished work shelves. Remember to pay for it before you head out the door! There is a small extra charge for using porcelain clay (it’s more than twice the price of regular clay), and for any third firing process! Once your work has been fired it can not turn back into clay for millennia – so don’t fire it if you don’t like it! Put it in the bucket for recycling. https://firebirdstudios.com.au/the-process-of-making-pottery/The form of the jug has been in use for many centuries.Stoneware jug.

Letting your work rest for a while can really help keep your work clean and professional looking. Many things require bagging under plastic to keep it ready for work the next week – put your name on the outside of the bag so you can find your work easily. We have stickers and markers. Consider how you want to decorate your work – coloured slip can be applied at a fairly wet stage (remembering that it will make your work even wetter!). Trying to apply slip to dry clay won’t work! If you want to do sgraffito – you will need to keep the work leather hard (a state of dryness where you can still work the clay with a little effort and a little water and care). Step Three – Drying Most of the time your work can go into the rack uncovered to let it dry out for the following week. If you want to continue forming or shaping you will need to double bag your work – put your work on a suitable sized bat and put the bat in a bag so the base of the bag is under the bat, then put another bag over the top of the work and tuck the top of the bag under the bat. If you want to trim (or turn) your thrown work the following week, it should also be double bagged. If your work is large, delicate, or of uneven thicknesses, you should lightly cover your work for drying. When considering the drying process, bare in mind the weather, humidity and wind! The hotter and dryer, the faster things dry and work can dry unevenly in the shelves – this can lead to cracking – another time to lightly cover your work for drying. Step Four – Trimming and Cleaning Up Your work is dry! It is called greenware now and it is at it’s most fragile! Handle everything with two hands. I often refer to soft hands – keep everything gentle and with your fingers spread as much as possible. Try to not pick up things like plates too much, and always with both hands! Before your work can be bisque fired it should be “cleaned up”. You work won’t go into the kiln if it has sharp edges – when glazed, sharp edges turn into razor blades! Use a piece of fly wire to rub the work all over – this will scratch a little so be light handed. Use a knife or metal kidney to scrape any areas that require a bit more dynamic treatment than the fly wire offers! Finally, a very light wipe over with a slightly damp sponge can help soften and soothe all of your edges and dags! Trimming thrown work: If you are planning to trim (or turn) your thrown work (and you should be), make sure you bag it well – your work should be leather hard to almost dry for easiest trimming. Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. Wipe the sponge around the rim after trimming, and check the inside of the pot for dags! Trimming slip cast work: Usually I will trim the rims of your work on the wheel the following day to make that stage easier, however you will still need to check your work for lumps and bumps. Last but not least – check that your name is still clearly on the bottom of your work. Step Five – Bisque Firing When the work is completely dry it can go into the bisque kiln. The bisque kiln is fired to 1000°C. This process burns off the water in the clay as well as some of the chemically bound water. The structure of the clay is not altered that much at this temperature. Inside the bisque kiln, the work is stacked a little, small bowl inside a larger bowl and onto a heavy plate. Smaller items like decorations or drink coasters might get stacked several high. Consideration is paid to the weight of the stack and shape of the work. A bisque kiln can fire about one and a half times the amount of work that the glaze kiln can fire. The firing takes about 10 hours to complete the cycle and about two days to cool down. Once it has been emptied the work is placed in the glaze room ready for you to decorate! Step Six – Glazing Decorating your work with colour can be a lot of fun – and time consuming! There are three main options for surface treatment at this stage: Oxide Washes Underglazes Glazes Washes and underglazes do not “glaze” the work – It will still need a layer of glaze to fully seal the clay (washes don’t need glaze on surfaces not designed for food or liquid as they can gloss up a little on their own). Underglazes are stable colourants that turn out pretty much how they look in the jar. They can be mixed with each other to form other colours and can be used like water colours to paint onto your work. Mostly they should have a clear glaze on top to seal them. Oxides are a different species – the pink oxide (cobalt) wash turns out bright blue for instance. They don’t always need a glaze on top, and some glazes can change the colour of the wash! The glazes need no other “glaze” on top! Be careful of unknown glaze interactions – you can put any combination of glaze in a bowl or on a plate, but only a single glaze on the outside of any vertical surface! Glazes are a chemical reaction under heat. We don’t know the exact chemicals in the Mayco glazes we use. I can guess by the way they interact with each other, however, on the whole, you need to test every idea you have, and not run the test on a vertical surface! Simply put, glaze is a layer of glass like substance that bonds with the clay underneath. Clay is made of silica, alumina and water. Glaze is made of mostly silica. Silica has a melting point of 1700°C and we fire to 1240°C. The silica requires a “flux” to help it melt at the lower temperature. Fluxes can be all sorts of chemicals – a common one is calcium – calcium has a melting point of 2500°C, however, together they both melt at a much lower temperature! Colourants are metal oxides like cobalt (blue), chrome (green through black), copper (green, blue, even red!), manganese (black, purple and pink) iron (red brown), etc. Different chemicals in the glaze can have dramatic effects. for example, barium carbonate (which we don’t use) turns manganese bright pink! Other elements can turn manganese dioxide brown, blue, purple and reddish brown. Manganese dioxide is a flux in and of itself as well. So, glazes that get their black and purple colours, often interact with other glazes and RUN! Our mirror black is a good example – it mixes really well with many glazes because it fluxes them – causes them to melt faster. It will also bring out many beautiful colours in the glazes because it’s black colouring most definitely comes from manganese dioxide! Glaze chemistry is a whole subject on it’s own! We use commercial Mayco glazes on purpose – for their huge range of colour possibilities, stability, cool interactions, artistic freedom with the ability to easily brush the glazes on and ease of use. We currently have almost 50 glazes on hand! A major project is to test the interactions of all glazes with each other. That is 2,500 test tiles!!!! I’m going to make the wall behind the wheels the feature wall of pretty colours! Step Seven – Glaze (Gloss or sometimes called “Glost”) Firing Most of the time this is the final stage of making your creation (but not always!) The glaze kiln goes to 1240°C. This is called cone 6, or midrange. It is the low end of stoneware temperatures. Stoneware clays and glazes are typically fired at cone 8 – 10, that is 1260 – 1290°C. The energy requirement to go from 1240°C to 1280°C is almost a 30% more! Our clay is formulated to vitrify (mature, turn “glass-like”) at 1240°, as are our glazes. A glaze kiln take around 12 hours to reach temperature and two to three days to cool down. Sometimes a third firing process is required – this is for decoration that is added to work after the glaze firing. For example – adding precious metals and lustres. this firing temperature is usually around 600 – 800°C depending upon the techniques being used. There are many students interested in gold and silver trims – we will be doing this third type of firing soon! After firing your work will be in the student finished work shelves. Remember to pay for it before you head out the door! There is a small extra charge for using porcelain clay (it’s more than twice the price of regular clay), and for any third firing process! Once your work has been fired it can not turn back into clay for millennia – so don’t fire it if you don’t like it! Put it in the bucket for recycling. https://firebirdstudios.com.au/the-process-of-making-pottery/ The bowl is an example of kitchenware used in the 19th century and still in use today.Bowl white ceramic.

Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. ...The Process of Making Pottery Decorating, Firing, Glazing, Making, Technical There is a rhythm and flow to clay. It can’t be done all at once! Even the making process! It can take weeks to get everything done, especially if you can only work on your pottery once a week! Even though we have three hour classes, it’s often just not enough time! Here is an overview of some of the processes so you have a bit more grasp on some of the technical stuff! Step One – Design There are SO many ideas out there for making stuff in clay! From delicate porcelain jewellery, through to heavy sculptural work and everything in between. Deciding your direction is sometimes not that easy – when you first start, try everything, you will naturally gravitate to the style that you enjoy! The options and variations are endless and can get a wee bit overwhelming too! Check in with me before you start to ensure your ideas will work, what order you might do things, how you could achieve the look you are seeking and any other technical data required! Step Two – Making Clay is thixotropic. This means that as you work with it, the clay first gets sloppier and wetter, before is begins to dry in the atmosphere. For most things, you simply can’t do all parts of the project at once.

A seemingly perfect material for cooking, it is therefore no surprise that it has been used in kitchens for millennia. But exactly when did we learn to utilise copper and its valuable assets? Origins It is hard ...It is no secret that copper is currently experiencing a huge upsurge in popularity. This is mainly thanks to its beautiful colour featuring heavily in the ranges of countless homeware retailers. There is, however, far more to this lustrous metal than just its appearance. For example, it has a greater level of thermal conductivity than any other metal (except silver); roughly 60% higher than aluminium and 3000% higher than stainless steel. This means copper is capable of heating up very quickly when compared to other metals. Perhaps a less commonly known property of copper is it being inherently antimicrobial. A wide range of harmful microbes are unable to survive for more than a couple of hours when in contact with a surface made of copper or one of its alloys (brass and bronze). This has led to it often being used for frequently touched surfaces such as door knobs, push plates and taps. A seemingly perfect material for cooking, it is therefore no surprise that it has been used in kitchens for millennia. But exactly when did we learn to utilise copper and its valuable assets? Origins It is hard to pin down an exact date when copper cookware was first introduced. Pieces discovered in regions of the middle east were dated as far back as 9000BC, suggesting cooking with copper began during the Neolithic period (≈10000-2000BC). As civilisations became increasingly capable in metallurgical techniques, metals such as copper became more widely used. It would have been around this time that copper replaced stone as the material used for making tools and cooking vessels. The use of copper is also well documented in Ancient Egypt. Not only was it used to produce water and oil containers, but it was also used to in medical practices. The antimicrobial nature of copper was exploited long before the concept of microorganisms was fully understood. The Smith Papyrus, a medical text written between 2600 and 2200BC records the use of copper in sterilising wounds and drinking water. Tin Lining Although copper is essential to many processes within the human body, it can become toxic if consumed in excess. It was this knowledge that gave rise to lining cookware with tin, a technique used for hundreds of years to prevent copper leaching in to food. These tin linings would eventually wear out and during the 18th and 19th century, it was common for people to send pans away to be re-tinned. This practice is becoming increasingly rare, as are the craftsmen who perform it. Despite this, there are still manufactures producing tin-lined copper cookware who also offer a re-lining service. Perhaps the best known of these is Mauviel, a French manufacturer who have been making this type of cookware since 1830. Tin has now largely been replaced by stainless steel as an interior cooking surface. Not only is it more cost effective, but the high grade of stainless steel used in premium cookware (typically 18/10) is highly resistant to corrosion and more durable than tin.Copper saucepans are still used in many kitchens.Small copper saucepan with long handle and three ridges around the circumference.

The Beechworth Burke MuseumGeological specimen - Actionlite and Pyrite
... It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. ...Actinolite is usually found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of the metamorphism of magnesium-rich limestones. Pyrite is usually found with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well coal beds, and as a replacement mineral in fossils. Actinolite is an amphibole silicate mineral. It is named after the Greek word "aktinos" meaning “ray” in allusion to the mineral's fibrous nature. Fibrous actinolite is a type of asbestos and was once mined along Jones Creek at Gundagai, New South Wales. Pyrite or "Fool's Gold" is the most common sulfide mineral. It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. Most importantly, pyrite is an ore of gold. Pyrite is sometimes used as a gemstone but is not great for jewellery as it easily tarnishes. In some fossils of ammonites – shelled cephalopods that died ~66 million years ago – pyrite also replaces the shell. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. A small-medium-sized solid specimen with the minerals actinolite (dark green fibrous) and pyrite (brassy) with shades of brown, black/grey, and white. Actinolite is an amphibole mineral in the tremolite-actinolite series of calcium, magnesium, and iron silicates.

... Rather than their decorative patterns being glazed onto the surface of the tile, their inlaid designs were created during the manufacturing process, as “coloured slips” (or liquid clay) were poured into a deep pre-moulded casting. When fired, the resulting tile was colour-fast and design-fast. The Minton floor tile is significant for its hard ...This Minton floor tile is from the wreck of the Loch Ard. The iron-hulled clipper ship from the Loch Line was heading for Port Phillip from London, when it ran into the cliffs of Mutton Bird Island near Port Campbell. The Loch Ard was laden with high-value cargo including luxury goods intended for display at the Melbourne International Exhibition in 1880. One notable survivor from the ship’s freight manifest was the well-packed Minton porcelain peacock, a two-meter high ceramic masterpiece of vivid glazed colours. (This is also on display in the Great Circle Gallery). The almost total loss of life and property from the Loch Ard registered as a shocking tragedy for the Colony of Victoria, at a time when social confidence and economic optimism were otherwise high. The wealth generated from Gold and Wool was increasingly being spent on grandiose private residences and imposing public buildings. The demand for quality furnishings and fittings was therefore strong. Among the products consigned to burgeoning colonial markets by the Milton Pottery at Stoke upon Trent, were their new range of colourfully patterned but very durable floor tiles ideal for the high-traffic spaces in the large civic buildings then being constructed in Australia and America. These floor tiles were “encaustic”, meaning that their designs and colours were encased “within” the depth of the tile. Rather than their decorative patterns being glazed onto the surface of the tile, their inlaid designs were created during the manufacturing process, as “coloured slips” (or liquid clay) were poured into a deep pre-moulded casting. When fired, the resulting tile was colour-fast and design-fast. The Minton floor tile is significant for its hard-wearing yet attractive design. The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulations of artefacts from this notable Victorian shipwreck of which the subject items are a small part. The collections of objects give us a snapshot of how we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time.

The shape and texture of this wood sample suggests a dense hardwood like Oak. The timber has been cut off at one end since its recovery from the sea, exposing a smooth and almost shiny surface ...The artefact is a piece of ship’s timber from the wreck-site of the SCHOMBERG, a vessel which collided with the Peterborough reef on her maiden voyage in December 1855. This small wooden remnant of the disaster has been concreted on one side by the accrual of marine sediment while submerged. The build-up of sediment over the remains of the vessel is typical of the site as a whole. This artefact illustrates the reclaiming power of the ocean and the gradual disappearance of timber constructed vessels that have come to grief along this coastline (for example, the THISTLE in 1837, and the CHILDREN in 1838). The SCHOMBERG was a 2,000 ton clipper ship, specifically designed for the Australian immigration trade (back-loading wool for Britain’s mills), and constructed in Hall’s shipyard in Aberdeen, Scotland. She was owned by the Black Ball Line and launched in 1855. Alexander Hall & Son were renowned builders of sleek and fast 1,000 ton clippers for the China trade (opium in, tea out) and were keen to show they could also outclass the big North American ships built by Donald Mackay. Consequently the SCHOMBERG was ‘overbuilt’. Her hull featured five ‘skins’ of Scotch Larch and Pitch Pine overlaying each other in a diagonal pattern against a stout frame of British Oak. Oak has been favoured by builders of wooden ships for centuries. Its close, dense grain made it harder to work, but also gave it great strength and durability. In addition, the lateral spread of its branches supplied a natural curvature for the ribs of a vessel’s hull, as well as providing the small corner or curved pieces (‘knees’ and ‘elbows’) that fit them together. The shape and texture of this wood sample suggests a dense hardwood like Oak. The timber has been cut off at one end since its recovery from the sea, exposing a smooth and almost shiny surface. Seasoned English Oak has a similar light brown colour and tight grained finish. At the launch the SCHOMBERG’s 34 year old master, Captain ‘Bully’ Forbes, had promised Melbourne in 60 days, "with or without the help of God." James Nicol Forbes was born in Aberdeen in 1821 and rose to fame with his record-breaking voyages on the famous Black Ball Line ships; MARCO POLO and LIGHTNING. In 1852 in the MARCO POLO he made the record passage from London to Melbourne in 68 days. There were 53 deaths on the voyage but the great news was of the record passage by the master. In 1954 Captain Forbes took the clipper LIGHTNING to Melbourne in 76 days and back in 63 days, this was never beaten by a sailing ship. He often drove his crew and ship to breaking point to beat his own records. He cared little for the comfort of the passengers. On this, the SCHOMBERG’s maiden voyage, he was going to break records. SCHOMBERG departed Liverpool on her maiden voyage on 6 October 1855 flying the sign “Sixty Days to Melbourne”. She departed with 430 passengers and 3000 tons cargo including iron rails and equipment intended to build the Melbourne to Geelong Railway and a bridge over the Yarra from Melbourne to Hawthorn. She also carried a cow for fresh milk, pens for fowls and pigs, 90,000 gallons of water for washing and drinking. It also carried 17,000 letters and 31,800 newspapers. The ship and cargo was insured for $300,000, a fortune for the time. The winds were poor as she sailed across the equator, slowing SCHOMBERG’s journey considerably. Land was first sighted on Christmas Day, at Cape Bridgewater near Portland, and Captain Forbes followed the coastline towards Melbourne. Forbes was said to be playing cards when called by the Third Mate Henry Keen, who reported land about 3 miles off, Due in large part to the captain's regarding a card game as more important than his ship, it eventually ran aground on a sand spit near Curdie's Inlet (about 56 km west of Cape Otway) on 26 December 1855, 78 days after leaving Liverpool. The sand spit and the currents were not marked on Forbes’s map. Overnight, the crew launched a lifeboat to find a safe place to land the ship’s passengers. The scouting party returned to SCHOMBERG and advised Forbes that it was best to wait until morning because the rough seas could easily overturn the small lifeboats. The ship’s Chief Officer spotted SS QUEEN at dawn and signalled the steamer. The master of the SS QUEEN approached the stranded vessel and all of SCHOMBERG’s passengers and crew were able to disembark safely. The SCHOMBERG was lost and with her, Forbes’ reputation. The Black Ball Line’s Melbourne agent sent a steamer to retrieve the passengers’ baggage from the SCHOMBERG. Other steamers helped unload her cargo until the weather changed and prevented the salvage teams from accessing the ship. Later one plunderer found a case of Wellington boots, but alas, all were for the left foot! Local merchants Manifold & Bostock bought the wreck and cargo, but did not attempt to salvage the cargo still on board the ship. They eventually sold it on to a Melbourne businessman and two seafarers. In 1864 after two of the men drowned when they tried to reach SCHOMBERG, salvage efforts were abandoned. Parts of the SCHOMBERG were washed ashore on the south island of New Zealand in 1870, nearly 15 years after the wreck. The wreck now lies in almost 9 metres of water. Although the woodwork is mostly disintegrated the shape of the ship can still be seen due to the remaining railway irons, girders and the ship’s frame. A variety of goods and materials can be seen scattered about nearby. Flagstaff Hill holds many items salvaged from the SCHOMBERG including a ciborium (in which a diamond ring was concealed), communion set, ship fittings and equipment, personal effects, a lithograph, tickets and photograph from the SCHOMBERG. One of the SCHOMBERG bells is in the Warrnambool Library. The SCHOMBERG collection as a whole is of historical and archaeological significance at a State level, listed on the Victorian Heritage Register VHR S612. Flagstaff Hill’s collection of artefacts from the SCHOMBERG is significant for its association with the Victorian Heritage Registered shipwreck. The collection is primarily significant because of the relationship between the objects, as together they have a high potential to interpret the story of the SCHOMBERG. The SCHOMBERG collection is archaeologically significant as the remains of an international passenger ship. The shipwreck collection is historically significant for representing aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 of Victoria’s Framework of Historical Themes (living with natural processes). The collection is also historically significant for its association with the shipwreck and the ship, which was designed to be fastest and most luxurious of its day.

The timber has been cut off at one end since its recovery from the sea, exposing a smooth and almost shiny surface ...The object is a mass of small shipwreck debris that has been concreted together by sediment and marine growth. It was retrieved from the wreck-site of the SCHOMBERG, which ran aground near the mouth of the Curdies River near Peterborough in 1855. The conglomerate of preserved wood impressions, rusted metal pieces, a small square of copper alloy, and black glass-like stones, presents too disjointed a collection to provide information on their purpose or function on the ship. The natural and gradual process of limestone accretion is a significant feature of the wreck-site, which was rediscovered by fishermen and skindivers in 1973. In his book “Exploring Shipwrecks of Western Victoria”, experienced diver and former director at Flagstaff Hill, Peter Ronald writes that the SCHOMBERG’s “triple layered wooden hull has disintegrated almost without trace…The turbulent shallow waters have promoted particularly heavy marine growth which tend to disguise the wreckage…the most prominent feature being a corroded mass of railway iron…Close inspection reveals small artefacts firmly embedded in the marine concretion which…is quite literally as hard as iron”. The huge oblong mass of concretion that now distinguishes the site covers the remains of this heavy cargo. A contemporary account of the SCHOMBERG’s fate (told by two of her passengers to the Melbourne Argus) alleges the ship “was overloaded, drawing over 25 feet when she left, and the cargo was chiefly iron and plant for the Geelong Railway”. The SCHOMBERG was a 2,000 ton clipper ship, specifically designed for the Australian immigration trade (back-loading wool for Britain’s mills), and constructed in Hall’s shipyard in Aberdeen, Scotland.

Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. ...The Process of Making Pottery Decorating, Firing, Glazing, Making, Technical There is a rhythm and flow to clay. It can’t be done all at once! Even the making process! It can take weeks to get everything done, especially if you can only work on your pottery once a week! Even though we have three hour classes, it’s often just not enough time! Here is an overview of some of the processes so you have a bit more grasp on some of the technical stuff! Step One – Design There are SO many ideas out there for making stuff in clay! From delicate porcelain jewellery, through to heavy sculptural work and everything in between. Deciding your direction is sometimes not that easy – when you first start, try everything, you will naturally gravitate to the style that you enjoy! The options and variations are endless and can get a wee bit overwhelming too! Check in with me before you start to ensure your ideas will work, what order you might do things, how you could achieve the look you are seeking and any other technical data required! Step Two – Making Clay is thixotropic. This means that as you work with it, the clay first gets sloppier and wetter, before is begins to dry in the atmosphere. For most things, you simply can’t do all parts of the project at once. An example of work order might look like: Get last weeks work out from the shelves Prepare clay for today’s work – roll your clay, prepare balls for throwing, make the first stage of a pinch pot) Clean up last week’s work and put it on the shelf for bisque firing Check that you have any glazing to do – and do enough of it that you will have time to finish your main project Do the next step of your next project – there might be a further step that can’t be complete immediately, in that case, wrap your work well and put onto the shelves. Letting your work rest for a while can really help keep your work clean and professional looking. Many things require bagging under plastic to keep it ready for work the next week – put your name on the outside of the bag so you can find your work easily. We have stickers and markers. Consider how you want to decorate your work – coloured slip can be applied at a fairly wet stage (remembering that it will make your work even wetter!). Trying to apply slip to dry clay won’t work! If you want to do sgraffito – you will need to keep the work leather hard (a state of dryness where you can still work the clay with a little effort and a little water and care). Step Three – Drying Most of the time your work can go into the rack uncovered to let it dry out for the following week. If you want to continue forming or shaping you will need to double bag your work – put your work on a suitable sized bat and put the bat in a bag so the base of the bag is under the bat, then put another bag over the top of the work and tuck the top of the bag under the bat. If you want to trim (or turn) your thrown work the following week, it should also be double bagged. If your work is large, delicate, or of uneven thicknesses, you should lightly cover your work for drying. When considering the drying process, bare in mind the weather, humidity and wind! The hotter and dryer, the faster things dry and work can dry unevenly in the shelves – this can lead to cracking – another time to lightly cover your work for drying. Step Four – Trimming and Cleaning Up Your work is dry! It is called greenware now and it is at it’s most fragile! Handle everything with two hands. I often refer to soft hands – keep everything gentle and with your fingers spread as much as possible. Try to not pick up things like plates too much, and always with both hands! Before your work can be bisque fired it should be “cleaned up”. You work won’t go into the kiln if it has sharp edges – when glazed, sharp edges turn into razor blades! Use a piece of fly wire to rub the work all over – this will scratch a little so be light handed. Use a knife or metal kidney to scrape any areas that require a bit more dynamic treatment than the fly wire offers! Finally, a very light wipe over with a slightly damp sponge can help soften and soothe all of your edges and dags! Trimming thrown work: If you are planning to trim (or turn) your thrown work (and you should be), make sure you bag it well – your work should be leather hard to almost dry for easiest trimming. Use this step to finish the work completely – use a metal kidney to polish the surface, or a slightly damp sponge to give a freshly thrown look. Wipe the sponge around the rim after trimming, and check the inside of the pot for dags! Trimming slip cast work: Usually I will trim the rims of your work on the wheel the following day to make that stage easier, however you will still need to check your work for lumps and bumps. Last but not least – check that your name is still clearly on the bottom of your work. Step Five – Bisque Firing When the work is completely dry it can go into the bisque kiln. The bisque kiln is fired to 1000°C. This process burns off the water in the clay as well as some of the chemically bound water. The structure of the clay is not altered that much at this temperature. Inside the bisque kiln, the work is stacked a little, small bowl inside a larger bowl and onto a heavy plate. Smaller items like decorations or drink coasters might get stacked several high. Consideration is paid to the weight of the stack and shape of the work. A bisque kiln can fire about one and a half times the amount of work that the glaze kiln can fire. The firing takes about 10 hours to complete the cycle and about two days to cool down. Once it has been emptied the work is placed in the glaze room ready for you to decorate! Step Six – Glazing Decorating your work with colour can be a lot of fun – and time consuming! There are three main options for surface treatment at this stage: Oxide Washes Underglazes Glazes Washes and underglazes do not “glaze” the work – It will still need a layer of glaze to fully seal the clay (washes don’t need glaze on surfaces not designed for food or liquid as they can gloss up a little on their own). Underglazes are stable colourants that turn out pretty much how they look in the jar. They can be mixed with each other to form other colours and can be used like water colours to paint onto your work. Mostly they should have a clear glaze on top to seal them. Oxides are a different species – the pink oxide (cobalt) wash turns out bright blue for instance. They don’t always need a glaze on top, and some glazes can change the colour of the wash! The glazes need no other “glaze” on top! Be careful of unknown glaze interactions – you can put any combination of glaze in a bowl or on a plate, but only a single glaze on the outside of any vertical surface! Glazes are a chemical reaction under heat. We don’t know the exact chemicals in the Mayco glazes we use. I can guess by the way they interact with each other, however, on the whole, you need to test every idea you have, and not run the test on a vertical surface! Simply put, glaze is a layer of glass like substance that bonds with the clay underneath. Clay is made of silica, alumina and water. Glaze is made of mostly silica. Silica has a melting point of 1700°C and we fire to 1240°C. The silica requires a “flux” to help it melt at the lower temperature. Fluxes can be all sorts of chemicals – a common one is calcium – calcium has a melting point of 2500°C, however, together they both melt at a much lower temperature! Colourants are metal oxides like cobalt (blue), chrome (green through black), copper (green, blue, even red!), manganese (black, purple and pink) iron (red brown), etc. Different chemicals in the glaze can have dramatic effects. for example, barium carbonate (which we don’t use) turns manganese bright pink! Other elements can turn manganese dioxide brown, blue, purple and reddish brown. Manganese dioxide is a flux in and of itself as well. So, glazes that get their black and purple colours, often interact with other glazes and RUN! Our mirror black is a good example – it mixes really well with many glazes because it fluxes them – causes them to melt faster. It will also bring out many beautiful colours in the glazes because it’s black colouring most definitely comes from manganese dioxide! Glaze chemistry is a whole subject on it’s own! We use commercial Mayco glazes on purpose – for their huge range of colour possibilities, stability, cool interactions, artistic freedom with the ability to easily brush the glazes on and ease of use. We currently have almost 50 glazes on hand! A major project is to test the interactions of all glazes with each other. That is 2,500 test tiles!!!! I’m going to make the wall behind the wheels the feature wall of pretty colours! Step Seven – Glaze (Gloss or sometimes called “Glost”) Firing Most of the time this is the final stage of making your creation (but not always!) The glaze kiln goes to 1240°C. This is called cone 6, or midrange. It is the low end of stoneware temperatures. Stoneware clays and glazes are typically fired at cone 8 – 10, that is 1260 – 1290°C. The energy requirement to go from 1240°C to 1280°C is almost a 30% more! Our clay is formulated to vitrify (mature, turn “glass-like”) at 1240°, as are our glazes. A glaze kiln take around 12 hours to reach temperature and two to three days to cool down. Sometimes a third firing process is required – this is for decoration that is added to work after the glaze firing. For example – adding precious metals and lustres. this firing temperature is usually around 600 – 800°C depending upon the techniques being used. There are many students interested in gold and silver trims – we will be doing this third type of firing soon! After firing your work will be in the student finished work shelves. Remember to pay for it before you head out the door! There is a small extra charge for using porcelain clay (it’s more than twice the price of regular clay), and for any third firing process! Once your work has been fired it can not turn back into clay for millennia – so don’t fire it if you don’t like it! Put it in the bucket for recycling. https://firebirdstudios.com.au/the-process-of-making-pottery/Ceramics have evolved over thousands of years.White earthenware dinner plate.
