Fluorite comes in a variety of natural colours and crystal formations and glows under ultraviolet light (the word 'fluorescence' comes from the same etymological source). In its pure form, calcium fluoride, it is a colourless combination of the elements calcium and fluorine, but gains its colour from trace elements that infiltrate or replace calcium within its crystal structure during its formation. Although fluorite crystals polish well and can achieve a high level of lustre, the mineral is very soft (4 on MOHS hardness scale) so it is unsuitable for use in rings and must be handled and stored carefully if used in other forms of jewellery. Most crystals of the mineral are too coarse for decorative purposes but have been mined under the name fluorspar for a variety of commercial and industrial purposes. These include the production of hydrofluoric acid, smelting metal alloys, producing glazes and ceramic finishes and use in medical and dental products. An existing label for this specimen indicates that its origin or collection-point was 'probably USA.' Fluorspar, the form of fluorite used commercially and industrially, was mined in significant quantities in the counties of Hardin and Pope in South-Eastern Illinois throughout the Nineteenth and Twentieth Centuries. Fluorite was made Illinois' state mineral in recognition of its contribution to the state's identity and economy. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.The specimen is a piece of purple shaded fluorite (also known as fluorspar), the mineral form of calcium fluoride.

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. 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.Hand-sized piece of pale pink dolomite (calcium magnesium carbonate) with dark grey rim and hollowed centre. geological specimen, geology, geology collection, burke museum, beechworth, dolomite, mineralogy, geological survey, alfred selwyn, limestone, calcium magnesium carbonate

Calcite is a common mineral and is found worldwide due to it being a primary component of many other rocks such as limestone and marble. It is a softer mineral that scratches easily and is often found colourless or with a cream/white shade but may show up in colours such as red, yellow, green, and violet. In sedimentary rocks calcite is often found in the form of invertebrate shells, making it an important biomineral. Calcite is used in many industries such as farming, building, and medicine. This particular specimen was found at Broken Hill mine in Broken Hill, New South Wales, Australia. Broken Hill mine is one of the largest mines working silver and lead in Australia and at its peak employed 6500 staff across 7.5km long of land. The site was founded in 1883 by Charles Rasp, where Rasp and 6 other men from various backgrounds came together to form the first BHP mine. It has become one of the most popular mining sites due to its abundance and longevity. The ore body was created 1685 million years ago due to volcanic activity causing heated seawater to flow up through the seafloor where it mixed with the cold water creating black sulphide precipitates. These then settled back onto the seafloor forming sediment layers rich in minerals. Over time the land eroded until it was discoverable by humans.Historically this specimen is significant due to the origin of its location. Broken Hill mine has a long history in both its location and its findings and has resulted in a variety of minerals being discovered at its site. It is beneficial in the understanding of the Australian landscape over millions of years. Due to its properties, calcite today is used in a multitude of different industries such as agriculture, construction, medicine, and farming.A small sized calcium, carbon and oxygen made mineral specimen in shades cream and greycalcite, mineral, limestone, marble, sedimentary, invertebrate shells, biomineral, farming, medicine, broken hill, broken hill mine, new south wales, charles rasp, syndicate of seven, volcanic activity, black sulphide precipitates, calcite crystals, beechworth museum, indigo shire, beechworth

Robin WELCH ( 23 July 1936-5 December 2019) Born Nuneaton, Warwickshire, England Robin Welch is one of the most highly respected contemporary British potters. The full range of his work includes large vessels with related paintings, fine drawings, and distinctive bowls and vases which explore colour, surface texture, form, detail of edge, and line. He is one of small group of significant British potters who expanded the language of throwing pots on the wheel through post-wheel additions and alteration. This gave his generally cylindrical forms a more organic and sculptural aspect, but their heavily coloured and textured surfaces were as much about painting, too, as Robin sought an integration of the visual disciplines he enjoyed. As he once wrote: “There’s no divide between art or craft. You decide to be an artist and you’ll use anything. If marooned on a desert island you’d use driftwood.” (https://www.theguardian.com/artanddesign/2019/dec/27/robin-welch-obituary, accessed 23 March 2021) Initially studying at Penzance School of Art under Michael Leach (son of Bernard Leach) and the Central School of Art, London Robin Welch then worked part-time at the Leach Pottery between 1953 and 1959 before opening his own pottery in London's west end (1960 to 1962). After a couple of years of world travel, including working in Australia from 1962 to1965 helping Ian Sprague set up his Mungeribar Pottery and exhibiting in Melbourne, Robin Welch returned to England setting up Stadbroke Pottery in Eye, Suffolk in 1965. Apart from his studion work Robnin Welch was a skilled designer for industry including Wedgwood. When not in his Suffolk studio Robin Welch spent much time in Australia where he appreciated the outback’s arid earth, brilliant light, grittier textures and luminous colour.

Francis Powell (1861-) and Francis Hanmer (1858-1925) founded Powell and Hanmer Ltd in the Summer of 1885 for the manufacturer of bike and carriage lamps. Their first advertisements began to appear in November of 1885. In 1890 they lodged a Patent for “velocipede” lamps to be used by lightweight wheeled vehicles propelled by a rider, such as a bike, tricycle and railroad handcar. In April of 1913, they were selling headlamps for cars and in 1914 built their second factory manufacturing dynamo lighting sets in Rocky Lane Birmingham, also for the production of dynamos for motor cars. Then in 1929 Powell and Hanmer Ltd, was acquired by the Lucas company which was at that time the main competitor for the manufacture of non-electrical equipment for cycles and motorcycles. When a director of Powell and Hanmer joined the board of Austin motor cars, Lucas feared that Austins might encourage Powell and Hanmer to start to produce electrical equipment for supply to the company and as a result this association might affect Lucas's business with other large vehicle manufacturers. As a result, Lucas made an offer to Powell & Hanmer and purchased the business for £500,000. Carbide lighting was used in rural and urban areas of Australia which were not served by electrification. Its use began shortly after 1900 in many countries and continued past the 1950s. Calcium carbide pellets were placed in a container outside the home, with water piped to the container and allowed to drip on the pellets releasing acetylene. This gas was piped to lighting fixtures inside the house, where it was burned, creating a very bright flame. Carbide lighting was inexpensive but was prone to gas leaks and explosions. Early models of the automobile, motorbike and bicycles used carbide lamps as headlamps. Acetylene gas, derived from carbide, enabled early automobiles to drive safely at night. Thick concave mirrors combined with magnifying lenses projected the acetylene flame light. These type of lights were used until reliable batteries and dynamos became available, and manufacturers switched to electric lights. Acetylene lamps were also used on riverboats for night navigation. The National Museum of Australia has a lamp made in about 1910 that was used onboard the PS Enterprise, an 1878 Australian paddle steamer, currently owned by the National Museum of Australia in Canberra. It is still operational, and one of the oldest working paddle steamers in the world, listed on the Australian Register of Historic Vehicles.Acetylene Carbide lamp, Model “Panther” distinct patterned side red and green lenses.

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.

Rhodonite is a reddish-pink manganese silicate material and often contains iron, magnesium and calcium. It is usually found in metamorphic rocks (rocks which have been altered by heat, pressure or chemical process). It can range in size from tiny to massive. Because of their composition they are not suitable for use in jewellery because they are hard enough. It is quite rare to find, though has been found in Australia, North America, South America and Europe.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.

These lamps belonged to Ernie Eaton and were used for spotlighting rabbits. Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C2H2) which is created by the reaction of calcium carbide (CaC2) with water. Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by cavers, hunters, and cataphiles Torches, candles, oil lamps and kerosene lamps were designed to be carried around but they could be dangerous because they have flame as a source of light.

It is thought that natural pearls form under a set of accidental conditions when a microscopic intruder or parasite enters a bivalve mollusc and settles inside the shell. The mollusc, irritated by the intruder, forms a pearl sac of external mantle tissue cells and secretes the calcium carbonate and conchiolin to cover the irritant. This secretion process is repeated many times, thus producing a pearl. Natural pearls come in many shapes, with perfectly round ones being comparatively rare. In general, cultured pearls are less valuable than natural pearls, whereas imitation pearls have almost no value. Cultured freshwater pearls can often be confused for natural pearls Cultured pearls are the response of the shell to a tissue implant. A tiny piece of mantle tissue (called a graft) from a donor shell is transplanted into a recipient shell, causing a pearl sac to form into which the tissue precipitates calcium carbonate. Some imitation pearls (also called shell pearls) are simply made of mother-of-pearl, coral or conch shell A strand of pearls called a princess length, 43 to 48 cm in length, comes down to or just below the collarbone. A graduated strand of pearls most often has at least 3 mm of differentiation from the ends to the centre of the necklace.

The most common technique to measure fuel moisture content in Victorian forests until recently was the Speedy Moisture Meter - which is essentially a pressure cylinder. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s. Fuel was first ground using a Spong domestic food mincer, often attached to the bullbar of a vehicle, and a small measured (using the beam balance) sample placed into the Speedy together with a measured amount of calcium carbide and then sealed. The chemical reaction between the moisture in the fuel and the calcium carbide created acetylene gas; the pressure of which was read on the external dial which gave the read-out as the moisture content (percentage of net weight) of the sample. There were important techniques with preparing the minced samples, using the chemical and the subsequent cleaning of the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field - it gave readings which were reproducible to within +/- 0.5% moisture content. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. In about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance.First reliable tool for measuring bushfire fuel moisture content in the fieldSpeedy Moisture Meter in wooden boxmanufacture's marks and instructions on usebushfire, forests commission victoria (fcv)

A Bioscope show was a fairground attraction consisting of a travelling cinema. The heyday of the Bioscope was from the late 1890s until World War I. Bioscope shows were fronted by the largest fairground organs, and these formed the entire public face of the show . A stage was usually in front of the organ, and dancing girls would entertain the crowds between film shows. Films shown in the Bioscope were primitive, and the earliest of these were made by the showmen themselves. Later, films were commercially produced. Bioscope shows were integrated, in Britain at least, into the Variety shows in the huge Music Halls which were built at the end of the nineteenth century. After the Music Hall Strike of 1907 in London, bioscope operators set up a trade union to represent them. There were about seventy operators in London at this point.

New Zealand Greenstone, also called Pounamu is found on New Zealand’s South Island in riverbeds and boulders, and colours vary depending on the source, but always include green tones. It is a form of the mineral nephrite, also known as jade, and is a tough stone with a crystalline structure, made up of calcium magnesium and iron silicate. Its hardness means it is ideal for carving, and has been used for this purpose throughout history, especially by the Maori people of New Zealand. Greenstone features heavily in Maori mythology, and the traditional name for the South Island, Te-Wai-Pounamu, literally translates to waters of greenstone. Wearing of Greenstone pendants with different carvings is practiced by Maori to represent connection to land and ancestors, or to endow the wearer with certain attributes. The sticker on the base of the specimen identifies it as a product of Hokitika Jade Company. The company, which was active in the 1970s, sold jade and greenstone specimens and ornaments. Hokitika, which started life as an 1860s gold rush town, is the origin of most nephrite found in New Zealand, and the centre of the Greenstone carving industry. The object has scientific and research potential as part of the Burke Museum's Geology Collection, and as and example of New Zealand Greenstone. It also has spiritual significance for it's role in Maori beliefs and communities, where it is both traditionally worn and features in mythology. As a valuable stone regularly used in carving and jewellery, it has aesthetic significance. Sticker on base: "N.Z.

Phosphatine Falieres was invented by pharmacist Émile Falières in the 1880s and marketed as a fortifying cereal or "farine" [flour] for infants, enriched with calcium. Said to be easily mixed and easily digestible, the cereal was added to an infant’s milk. It was made in Australia and distributed by a number of pharmaceutical companies, in the 1950s by Joubert & Joubert. The Phosphatine Falieres company advertised extensively, marketing to doctors, nurses, and mothers always using pictures of rosy-cheeked children. Falières created charming three-dimensional chromolithography pop-up/pop-out/moveable images many of which had a little tab. When the tab was pulled, these colourful sales props showed happy and healthy children opening a tureen of food that was fortified with Falieres cereal. The collection of Nurse Florence Green RWHA_2018_069 contains one such item of ephemera. Green was a graduate of the Women’s Hospital’s midwifery nurse training scheme in 1914. She lived at Hawthorn. The container is a cardboard cylinder with a printed label (stained) covering the entire surface. It has a metal (rusted) lid. The word "BORAX" has been written on the side.

Feldspar, derived from the German word feldspat, is a group of minerals which is the most common mineral group found on Earth, making up more than half of the planet's crust. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline. (Mindat, Feldspar Group). Orthoclase is part of the Feldspar Group subgroup, Alkaline Feldspar, which are known to be poor in calcium, and mostly rich in potassium. It is further also considered to be a K Feldspar, a subgroup of Alkaline Feldspar that are Potassium-dominant with variable crystal symmetry and Al-Si ordering state. Orthoclase are most commonly Colorless to white, Greenish white, Grayish yellow, or Pale pink and transparent to translucent with slightly pearly cleavage. The mineral rates at a 6 on the Mohs Hardness Scale. (cannot be scratched with a knife, but scratches glass with difficulty). The stronger green colour of this particular specimen is distinctive to the Broken Hill region (where it was found), and due to a small amount of lead. (BB) Its qualities find it misidentified at times as as microcline variety amazonite. Broken Hill is one of the world’s richest lead-zinc-silver deposits. The huge, 300-million-tonne orebody was discovered in 1883 and the superb mineral specimens attract collectors from around the world. (Australian Museum, Minerals from Australia: Australian mining regions)While feldspar is not by any means rare, this particular specimen has qualities distinctive to the Broken Hill mining district, with these properties leading at times to the mineral's misidentification. This creates potential for further study and identification of these mineral deposits through methods such as microscopic twinning, or using the position of certain d values in XRD patterns to calculate the degree of disorder of a K-feldspar, as discussed on the Mindat website (Mindat.com, Orthoclase:About Orthoclase). 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.

Bushfire behaviour is influenced by many things including temperature, relative humidity, forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), and also bushfire size, shape and direction. Fuel arrangement is as important as fuel quantity (tonnes/ha). Fibrous and ribbon bark, together with elevated and near-surface scrub fuels act as ladders which lead flames into the tree canopy. But the availability of fuel to burn depends largely on its moisture content. When it exceeds 20-25% not much will burn, whereas 12-15% is generally ideal for fuel reduction burning, but if the moisture content drops as low as 7-10% virtually everything will ignite, and fire behaviour becomes extreme. During the afternoon of the Ash Wednesday bushfires on 16 February 1983 fuel moisture contents were recorded at Stawell as low as 2.7%. Fine fuels like leaves and bark can rapidly absorb moisture after a shower of rain, or from the air when the Relative Humidity (RH) is high, and the temperature is low. Conversely, they can also dry out very quickly. So even though the overall fuel quantity in the forest doesn’t change, the fine fuel availability can increase rapidly from zero after rain to many tonnes per hectare as the fuel dries out. This can happen over a few hours on hot and windy days. Heavy fuels like logs on the ground take longer to dry out. Since the 1930s foresters, firefighters and researchers have been working to develop quick and reliable techniques for measuring fuel moisture content. One of the most accurate methods is slowly drying a sample of fuel in a conventional oven for 24-48 hours to remove all the moisture and measuring the weight difference, but this takes time and is not practical in the field when rapid measurements are needed. But oven drying is often used as a benchmark to compare other methods. Microwave ovens are faster but can cause uneven drying and even char the fuel. They are also not very practical for use in the field. Some mathematical models rely on weather records such as rainfall, wind speed, evaporation, cloud cover, shading, relative humidity, slope, aspect and season of the year to predict soil and fuel moisture. The Keetch-Byram Drought Index of soil dryness is the most common. But complex fuels with leaves, twigs, grass etc make the predictive models often inadequate for fine fuels. The most common technique in Victorian forests until recently was the trusty Speedy Moisture Meter. Originally developed in England during the 1920s for measuring moisture in wheat and other grains it was adapted for Australian forest fuels in the 1950s (I think). Fuel was first ground using a Spong mincer, often attached to the bullbar of a vehicle, and a small sample placed into the Speedy together with a measure of calcium carbide and then sealed. A chemical reaction created gas pressure which was read on the external dial. There were important techniques with cleaning, mincing and using the chemicals with the Speedy to give reliable readings, but it was quick, inexpensive, robust, portable and practical in the field. It was used routinely before igniting a fuel reduction burn or measuring fuel moisture differentials on slash burns. But in about 1996, Karen Chatto and Kevin Tolhurst from the Department’s Creswick Research Station developed the Wiltronics Fuel Moisture meter which measured electrical resistance. Wiltronics is an Australian owned company operating from Ballarat. The final result was a kit that was portable, accurate and could reliably measure fuel moisture contents between 3% and 200%. Although expensive, it is now widely used by fire agencies around the world which has virtually relegated the Speedy to the back cupboard.Prototype Fuel moisture meterT-H Fine Fuel Meterforests commission victoria (fcv), bushfire, forest measurement

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.
