Malachite is a copper carbonate hydroxide mineral. It has a chemical composition of Cu2(CO3)(OH)2. It often forms within limestone where a subsurface chemical environment favourable for the formation of carbonate minerals can occur. It is a substance that can be found in many different parts of the world including: Australia, USA, Russia and the Democratic Republic of Congo. Malachite has historically been used to produce copper, with mining of the mineral dating back over a period of four thousand years. Due to its beautiful green colourations, it is also commonly used for aesthetic purposes such as in the production of sculptures and jewellery. This particular specimen was collected from the town of Burra, South Australia as part of a geological survey undertaken during the nineteenth century. The locality (located on Ngadjuri Country) has a long history of mining, particularly in copper mining, as the area is rich in copper deposits. The first significant discovery of this was made in Burra (Burra Burra Mine) in 1845 and, at the time, the mine was the largest and richest of its kind in the world, producing nearly five percent of the total world copper output. This specimen is significant as it is considered to be a rare gemstone, as many of the original deposits for the stones are significantly depleted, leaving behind very few sources. 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 solid palm-sized copper carbonate hydroxide mineral with patterns of green colourations Existing Label: MALACHITE / Locality: Burra / S.

This specimen is a copper-carbonate malachite mineral. It is often found as crystalline aggregates or crusts, which have a banded agate-like appearance while also commonly found as botryoidal clusters of radiating crystals. Malachite is often bright green in colour, with dark green and blackish blooms or stripes/bands throughout the mineral. This particular specimen was recovered from the Burra Burra Copper Mine located Burra, South Australia. By the 1860's, South Australia was known as the "Copper Kingdom" due to its large amount of copper mines and huge success in the copper mining industry. Burra Burra was no exception to this phenomena, as this mining company was greatly famous and successful, being nicknamed the "Monster Mine". It was first established in 1848 and was the largest metal mine in Australia up until 1860. This specimen is significant as it highlights the historic use and value of malachite and the rarity of the mineral. Malachite is a rare gemstone which has been used in various ways historically. It has been cut and sculpted into beads for jewellery use as its rich colour and distinct yet unique patterns have made it a well sought after gemstone. Its' continued use over time only heightens the value and significance of this mineral.A hand-sized solid copper-carbonate hydroxide mineral specimen in shades of blue, green and copper tones throughout.MALACHITE / (Copper carbonite) / Locality: Burra, South Aust. | Malachite / Burra Burra / South Australia / (good specimen) / needs a wash / BBburke museum, burke museum collection, beechworth museum, beechworth, geological specimen, geological, mineral, mineraology, copper carbonate, malachite, burra burra mine, copper mining

Malachite is a green copper carbonate hydroxide mineral and was one of the first ores used to make copper metal. Malachite has been utilised as a gemstone and sculptural material in the past as its distinctive green color does not fade when exposed to light or after long periods of time. Malachite is formed at shallow depths in the ground, in the oxidizing zone above copper deposits. The material has also been used as a pigment for painting throughout history. This particular specimen was recovered from the Burra Burra Copper Mine in Burra, South Australia. Otherwise known as the 'Monster Mine', the Burra Burra Copper Mine was first established in 1848 upon the discovery of copper deposits in 1845. Within a few short years, people from around the world migrated to Burra to lay their claim in the copper economy. By April 1848 the mine was employing over 567 people and supporting a population of 1,500 in the local township. Up until 1860, the mine was the largest metals mine in Australia, producing approximately 50,000 tonnes of copper between 1845 to its closure in 1877. The Burra Burra Mine was also famous for a number of other specimens, including; crystalline azurite, cuprite, and botryoidal and malachite.Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. 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.

Malachite is typically found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well. Single crystals and clusters of distinguishable crystals are uncommon, but when found they are typically acicular to prismatic. It is also frequently found as a pseudomorph after Azurite crystals, which are generally more tabular in shape. This particular specimen was recovered from the Burra Burra Copper Mine in Burra, South Australia. Otherwise known as the 'Monster Mine', the Burra Burra Copper Mine was first established in 1848 upon the discovery of copper deposits in 1845.

Selwynite is a fine-grained, compact green rock made primarily of chromian muscovite (fuchsite) and diaspore. Corundum and fuchsite can occur together in the form of massive aggregates or nodules. Often, copper carbonates are found as earthy films or tiny crystals in joint planes. The mineral name honours the late A. R. C. Selwyn, founding Director of the Geological Survey of Victoria. The particular specimen, a mottled green stone suitable for carving was recovered and found in Heathcote, Victoria, Australia. The rarity and qualities of this mineral attracted commercial mining, which was not successful, but traces of the mine shafts still exist today, and it is still highly valued by mineral collectors.Selwynit is considered to be one of the rare forms of rock because it is composed of phosphate minerals containing zirconium. This is an extremely rare combination found in nature. 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.

Dolomite is a mineral, calcium magnesium carbonate, with the chemical formula CaMg(CO3)2. It is a principle component of various rock types sometimes also referred to as dolomite, including dolostone, dolomitic marble and dolomitic limestone (according to the composition of each type). Dolomite rock is found in sedimentary basins throughout the world, comprising approximately 2% of the Earth's crust. It is formed when lime mud or limestone encounters groundwater containing magnesium. Dolomite can contain elements such as lead, zinc and copper. Dolomite and limestone are used in various construction, landscaping and agricultural processes. This specimen was donated to the Burke Museum in 1868 by Alfred Selwyn as part of the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Dolomite and limestone are mined at several locations in Victoria, including sites in the North-East of the state in Bindi and Limestone Creek. There are notable dolomite deposits in most Australian states. The dolomitised form of the mineral tends to come from older limestone deposits, formed during the palaeozoic era in marine settings, so this specimen may have come from a deposit located along a coastline in Victoria or another state. The specimen is significant as an example of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century. 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.

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 bowl is an example of kitchenware used in the 19th century and still in use today.Bowl white ceramic.

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/ This bowl is an example of kitchenware used in the 19th century and still in use today.Bowl white ceramic plain that has two sets of edging around lip.

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!

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.A white earthenware side plate with a gadroon edge.

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!
