Methyl Sulphides
(Sir) David Orme Masson was Professor of Chemistry at the University of Melbourne from 1886 to1923. As well as being a distinguished teacher and researcher, he contributed significantly to Australian scientific and public life, being instrumental in the establishment and governance of many important bodies including the CSIRO. Masson supported Antarctic research for 25 years, beginning with Douglas Mawson?s expedition of 1911. Born in England and receiving an MA, BSc and DSc from the University of Edinburgh, he was a gifted, elegant and disciplined lecturer and a researcher of substance. His research work included the theory of solutions, from which emerged the term ?critical solution temperature?; the periodic classification of the elements; and the velocity of migration of ions in solutions. Much of his research was done in collaboration with talented students such as David Rivett and his own son Irvine Masson. Masson was knighted in 1923. He is commemorated by the Masson Theatre and Masson Road at the University of Melbourne; a mountain range and island in Antarctica; a portrait painting by William McInnes in the foyer of the School of Chemistry; the Masson lectureship from the Australian National Research Council; and the Masson memorial scholarship from the Royal Australian Chemical Institute.8 samples in bottles of the type used in Masson's work on methyl,etc,sulphides, See152 -

Photograph, Fay Bridge, The Tree Project, 2009
Australia's worst natural disaster, fed by extreme temperatures, tornado-like wind speeds and tinder-dry land, culminated in the disaster we now know as Black Saturday, February 7, 2009. Before the sun would set on the blackest day in Australia's history, thousands of hectares would become blackened landscape and an unparalleled loss of lives could only mean that many areas would never be the same again. To remember the people lost to the devastating Black Saturday fires of 2009 and our brave CFA men and women who battled the elements to protect our towns, the Australian Blacksmiths Association (Victoria) Inc. invited blacksmiths from across the country and around the world to contribute to the creation of a steel gumtree. The Blacksmiths' Tree, as it came to be called, was erected on February 14, 2014. Five years in the making, this 10m high stainless steel and copper tree was forged with love and care by hundreds of blacksmiths across 20 countries. It stands in the township of Strathewen, Victoria, Australia to remember all of those who perished in the Black Saturday fires of 2009, those who fought the fires and those who continue to live their lives with hope and courage. The tree stands at the Peter Avola Memorial Pavilion, 160 Chadds Creek Road, Strathewen, Victoria.fay bridge collection, black saturday, kinglake, victorian bushfires - 2009, the tree project -

Photograph, 12th September 2004 or 15rh September 2004
This photograph was taken at Wooragee Landcare workshop (Quoll), field day in Mt Pilot park on Bush Recovery: After the Fires. This is part of the Biodiversity Month on September 2004. The Bush Recovery workshop was held on Sunday 12th September 2-4pm with Christine Watson, Sue Berwick and Natasha Schedvin, and another workshop on Wednesday, 15th September, 9am to 12 noon with local biologist Glen Johnson and botanists Gill Earl and Christine Watson. The topics involved in the training involved what species have returned, what species haven't, what recovery studies are being carried out, how are the barking owls and phascogales faring, and why is Mt Pilot important. The photograph shows L-R: Colin Payne; Jerry Alexander; Geoff Galbraith. Bush fires are common in Australia due to several reasons. One is due to the geographic spread of fire's seasons, secondly, the absence of El Nino conditions are also linked to fires. Climate change also affected Australia's hot and dry seasons. Australia's climate began warming since the 1970s. Human-induced fires also contributed to this increase in temperatures across the nation. Bush fires happened in Mt Pilot in 2003 but it has recovered well since. This makes Mt Pilot an important site to understand bushfire recovery. This photograph contributes to the scientific and historical records on bushfire recovery in Victoria. It creates a picture of Victorian community activities and efforts on biodiversity, climate change, and environmental care.Landscape coloured photograph printed on gloss paperReverse: WAN NA 0A2A0N0 NN2 0 163 / (No. 2)wooragee, wooragee landcare group, wooragee landcare, bush fires, bush recover, mt pilot, biodiversity month, botany, botanists, bush recovery, quoll, foxy, fox, forest, environment, climate change, bushfire recovery, bushfires, 2004 bushfire, field work, after the fires, fire, biodiversity -
The Beechworth Burke Museum
Animal specimen - Wedgetail Eagle
The Wedgetail Eagle (aquila audax) is one of the largest birds of prey located in Australia, Indonesia and Papa New Guinea. It feasts mostly on rabbits but can target mammals as large as koalas, wombats, possums and small kangaroos. The darker the colouring, the older the bird is. A mostly dark brown feathering can suggest over 10 years old, though females are usually paler. This species mates monogamously for life. They circle high in the sky to avoid temperatures close to the ground and to assert their dominance over their territory. This specimen is lighter than many documented photographs of the species. They're usually less patchy / speckled with lighter colours on the chest and back. Documenting the wingspan of this specimen would be of interest because some have been measured up to 230cm. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century.This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.This wedgetail eagle is posed with the head turned to the left. It has mostly dark brown feathers which is common for older birds in this species. Speckled light brown and white feathers cover it's neck, chest and a middle strip across the wings. This specimen stands upon a wooden platform. The bill is light grey and long legs dark brown. taxidermy mount, taxidermy, animalia, burke museum, beechworth, australian museum, skin, reynell eveleigh johns, bird, wedgetail eagle, aquila audax, birds of prey, australian bird, eagle -

Domestic object - Hair Tongs, Marcel Grateau, 1900 +
Marcelling is a hair styling technique in which hot curling tongs are used to induce a curl into the hair. Its appearance was similar to that of a finger wave but it is created using a different method. Marcelled hair was a popular style for women's hair in the 1920s and 30s often in conjunction with a bob cut. For those women who had long hair, it was common to tie the hair at the nape of the neck and pin it above the ear with a stylish hairpin or flower. Accounts vary about the invention of the style, but Marcel Grateau (1852–1936) is widely credited with inventing the hair styling technique in the 1870s. He started with a small salon in Montmartre, Paris where his clients were the poorer classes. As he developed the waving method that would later become the Marcel wave, using heated curling irons, The inventor and stylist emigrated to the United States and changed his name to François Marcel Woelfflé, sometimes reported as François Marcel. He was granted U.S. patents for implements for performing the technique; the first, U.S. patent 806386, entitled "Curling-Iron", was published in 1905, and the second, entitled "Hair-Waving Iron", for an electric version, under the name François Marcel, was published in 1918. His obituary appeared under the name Francois Marcel Grateau in 1936. Originally the irons had to be heated in the fire, but hair easily got burnt until 1924 when electric irons were invented and the temperature could be regulated. A significant item that gives us a snapshot not only into women's hairstyles of the 1920s and 1930s but a look into the social norms of that era. Therefore the item is of social interest in regards to the story it tells and the development of women's fashion in hair styling.Marcel Tongs, metal, used to impart a hair wave by heating and crimping the hairNoneflagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, tongs, curling tongs, hairdressing -

Kitchen Equipment, china meat platter, c1900
Wedgwood was founded on 1 May 1759 by Josiah Wedgwood and in 1987 merged with Waterford Crystal to create Waterford Wedgwood, an Ireland-based luxury brands group. After the 2009 purchase by KPS Capital, Wedgwood became part of a group of companies known as WWRD Holdings Ltd, an acronym for "Waterford Wedgwood Royal Doulton." In 1765, Josiah Wedgwood created a new earthenware form which impressed the then British Queen consort Charlotte of Mecklenburg-Strelitz who gave permission to call it "Queen's Ware"; this new form sold extremely well across Europe. Wedgwood developed a number of further industrial innovations for his company, notably a way of measuring kiln temperatures accurately and new ware types Black Basalt and Jasper Ware. Wedgwood's most famous ware is jasperware. It was created to look like ancient cameo glass. It was inspired by the Portland Vase, a Roman vessel. Wedgwood had increasing success with hard paste porcelain which attempted to imitate the whiteness of tea-ware imported from China. High transportation costs and the demanding journey from the Far East meant that the supply of chinaware could not keep up with increasingly high demand. In 1812 Wedgwood produced their own bone china which, though not a commercial success at first eventually became an important part of an extremely profitable business.

Tool - Bullet Mould, From 1600s to early 19th century
Musket balls are the ammunition used in muskets the weapons used during the English and American Civil Wars. The balls could be made from any metal alloy, but many were made from lead. Lead can be melted at reasonably low temperatures and so lead musket balls could be made over a camp fire. Lead could be readily sourced from such places like church roofs or even coffins, and recast from old musket balls, so it was an easy material to work with while preparing for battle. The soldier would carry a crucible in which to melt the lead, he would put the material into it and place it over the fire until it had formed into a liquid. Musket ball moulds like the subject item, had a small hole above one of the domes where the liquid could be poured into once the two domes were closed together. The soldier would wait until it cooled then opened the mould to reveal a solid lead ball inside. Because these were cast in halves even though pressed together, there would always be a small amount of liquid lead leakage which would form a thin crust around the ball. These needed to be filed off before being used inside a musket, so some soldiers would pop a few in their mouths and roll them around, chewing off the excess until the ball was smooth. The obvious downside to this method is that lead is poisonous. A tool used to make ammunition for black powder firearms either muskets or pistols from the early part of the 18th to mid 19th century. After this time enclosed brass cartridges that held the propellent powder and bullet were starting to come into wide spread use, negating the need for a firearm to first have black powder placed in a barrel then the ball rammed on top and finally the firearm primed with powder or a percussion cap.Musket rifle/ pistol bullet mold.

Photograph - Colour, Phil Bryce, Removal of a fibre-glass chimney extension from a chimney from the former Ballarat Brewery, 2015, 13/11/2015
The chimney extension on what was the former Carlton and United Breweries boiler house at Ballarat installed in 1972 and it is constructed of a special formulation of fibreglass reinforced plastics designed to operate at elevated temperature (ie boiler flue gas). It is thought to be one of 26 or 28 fibreglass boiler chimneys designed and installed in Victoria in the 1970s, and is thought to be one of the last to be removed. In its day the fibreglass chimney extension was at the cutting edge of fibreglass technology and is therefore well worth retaining. Removal of the chimney extension to the brick chimney outside the brewery building was deemed necessary to prolong the life of the chimney, and also because the fibreglass extension had reached end of life and posing a possible threat. According an Engineering assessment, fibreglass structures have a life expectancy of between 20 years (when fatigue loaded) and up to 100 years (static loaded). We don’t know when it was added to the chimney but believe it was most likely in the early 1970s. Given that it is subject to wind load and often observed to be moving in the wind it is likely that it will be at the end of its life. The chimney will be made good and we have the necessary planning approvals in place to undertake the works. The chimney extension was removed on 13 November 2015 in accordance with a planning permit obtained by the University. The extension is believed to have been added in the 1970s and was predominantly made from fibre glass. The structure was removed for safety reasons and to preserve the integrity of the historic brick chimney which supported it.

Text panel, Elders Limited, "The Fleece that would not die"
Text panel produced by Elders to accompany display of coat. In 1928 Mr Mal Groves took over the Dutchman Station near Port Augusta in South Australia. Whilst out riding in some rough country he came across a sheep that had been left by the previous owner of the station. As he carried shears with him, he sheared the sheep and left the fleece rolled up and partially covered by rocks and wood, as he had no bag to carry it back with him. He intended to come back for the fleece, but forgot about it until he came across it some forty years later. It was still in good condition (despite having experienced extreme temperatures and rainfall whilst in the open), so he showed it to Elders who arranged to display it at agricultural shows in Adelaide, Melbourne and Geelong. The Gordon Institute of Technology, Geelong, offered to spin the fleece into a fabric and make a coat for Mrs Groves. The fabric was tailored into a coat by Lindsay and McKenzie of Geelong and presented to Mrs Groves in July 1968 by the SA manager of Elder Smith Goldsbrough Mort Ltd. It is not know how the coat came to Elders from the Groves family, but Elders displayed the coat under the heading "The Fleece That Would Not Die" before donating it to the National Wool Museum in 1997. A video giving the history of the coat as well as this text panel used by Elders were also donated at the same time.Text panel with black and red text on cream paper, framed in wooden frame and glass, with hanging wire.shearing, elders limited, groves, mr mal groves, dutchman station, south australia -

Photograph, A blue Harris electric train heads towards Union Road, Surrey Hills
The Harris blue electric trains were introduced in c1955 and followed the 'Red Rattlers'. They had a long life and were named after Norman Charles Harris, Chairman of Commissioners of the Victorian Railways, between 1940 and 1950. The first 30 7-carriage trains, known as the first series, were constructed in the United Kingdom by Gloucester Railway Carriage and Wagon Company, and delivered between 1956 and 1959. Another 30, the second series, were built by Martin & King in Melbourne, and delivered between 1961 and 1967. The trains had either two or three sets of hand-operated dual sliding doors per carriage side. Later they were fitted with power doors. Initially, until late 1978, the interiors were split into smoking and no-smoking compartments. In 1978 smoking on trains was abolished. Carriages were also designated as First or Second class until 1958, when one class travel was introduced. they had florescent lights but no heating. Most of the early carriages did not have end doors and gangways between carriages, but safety concerns led these being incorporated in the sets delivered from mid-1966. With the exceptions of the last few carriages built, all Harris trains contained asbestos insulation. The first sets contained blue asbestos, and the later sets contained white asbestos in the linings for insulation of noise and temperature. Due to the presence of asbestos, they began to be withdrawn from the mid-1980s and most were disposed of in the 1990s, by being buried at Talbot Quarry in Clayton, some having been wrapped in plastic. No original Harris trailer cars remain. A coloured photograph of a blue Harris electric train heading towards Surrey Hills station from Mont Albert station.

Ceramic, Malcolm Boyd, Untitled [Male Form] by Malcolm Boyd, 1977
MALCOLM BOYD Born Gippsland, Victoria In 1977 Malcolm Boyd graduated with a Diploma of Visual Arts from the Gippsland Institute of Advanced Education. It was at this time that he presented this work to the Jan Feder Memorial Ceramics Collection. Over thirty years later he still has a passion for ceramic history and design. Boyd operated the Black Cockatoo Pottery from around 1980-1995, starting in Essendon, then moving to Ascot Vale, Stratford, Bairnsdale and finally Fernbank in Gippsland. His handbuilt stoneware pots and clay sculptures are wood fired at his East Gippsland studio. He often uses ochre coloured dam banks on his property at Fernbank. The local clays are crushed, screened and blended with a white stoneware body to produce a number of shades and textures. All Malcolm Boyd's pot's are hand built using moulding, coiling, slabbing, and modelling techniques, and are high temperature fired (1300C) to allow some of the very ancient oriental glazes to mature. All works spend at least 20 hours in the wood fired kilns. This work is part of the Jan Feder Memorial Ceramics Collection which was amassed with funds raised by Jan Feder's student peers at the Gippsland Centre for Art and Design in the mid 1980s after Jan Feder passed away. Although many of the works are donated the intention of the collection was to purchase from visiting lecturers who became leading ceramic artists around the world, as well as from many of the staff who taught at the Churchill Campus. This work is part of the Jan Feder Memorial Ceramics Collection. Jan Feder was an alumna of the Gippsland Campus who studied ceramics on the campus. She passed away in the mid 1980s. Her student peers raised funds to buy ceramic works in her memory. They bought works from visiting lecturers who became leading ceramic artists around the world, as well as from many of the staff who taught there.malcolm boyd, ceramics, artist, artwork, jan feder memorial ceramics collection, gippsland campus, alumni -

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.

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.

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.

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.

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.

Household Equipment, Earthenware hot water bottle 'Hoffmann', c1900
Large stoneware hot water bottle also called a foot warmer. The stoneware hot water bottle has a rubber cap, often the original stone cap would be replaced with a cork alternative to seal the hot water. Because they were mass produced and very robust many survived so the antique value is not great. Many stoneware hot water bottles are still in use today and will be for years to come. Stoneware is a certain clay fired at a particularly high temperature and glazed so that it resembles polished stone.The bottle was filled with hot water, close the stopper securely and stand them in a bed, upright, on their small flat ends so that the sheets and blankets formed a tent-like structure over them. The peak of the 'tent' was the special feature of the rounded knob opposite the flat end, which also served as a carrying handle. Used this way, the hot water bottle was supposed to heat more of the bed Josef Hoffmann (1870–1956) attended the Academy of Fine Arts in Vienna and studied architecture under Otto Wagner. As a designer, Hoffmann was creative and prolific. His design portfolio encompassed commissions for buildings and interiors but extended to things as diverse as textiles, umbrella knobs, walking stick handles, tea pots, caskets and book covers as well as glass and ceramics.In 1903, with Koloman Moser and financier Fritz Waerndorfer, Hoffmann founded the Wiener Werkstätte. The collaboration of artists, designer architects and artisans enabled the realisation of the ‘total artwork’. Hoffmann’s designs were based on simple and clear proportions and employed rich, high-quality materials. Everyday objects were conceived as part of a whole living environment and were considered works of art.

Ceramic - Cover, circa 1883
This ceramic cover was recovered from the wreck of the 1882-1883 George Roper between the late 1960’s to early 1970’s. It is one of the shipwreck artefacts in the John Chance Collection. The purpose of the cover is unclear. The holes could be for ventilation. The cover may have been used to protect food or keep it at an even temperature. It may also have been used for covering fragrant petals, allowing some scent to escape through the holes. The residue around the underside of the holes and their random placement indicate that the cover could be partially handmade. The discolouration could have come from its time in the sea. The GEORGE ROPER 1882 - 1883 - The George Roper was a 4-masted iron sailing ship built in Liverpool, England, in 1882 for fast international trade with Australia. The large vessel was launched in February 1883. The ship was on its first trip, departing Liverpool for Melbourne, captained by John Ward and a crew of 31. She had almost reached her destination on July 4 1883, approaching Port Phillip Bay and being towed by the steam tug William. The weather changed to rough with fog and both the George Roper and the William hit the dangerous Lonsdale Reef at Port Phillip Heads. The Captain and crew were eventually rescued and taken to Queenscliff. Salvage syndicates were able to recover a lot of the cargo before the George Roper broke up and sank. Amongst the cargo was soft goods, draperies, household items, spirits of malt and distilled liquors, chemicals, dynamite, and 1,400 tons of steel rails for the Victorian Government. Also in the hold were Russell Stourbridge bricks, as paying ballast. The ventilated cover is as an example of domestic ceramic ware of the 1880s. The cover also holds significance as it was recovered by John Chance, a diver from the wreck of the George Groper in the 1960s-70s. Items that come from several wrecks along Victoria's coast have since been donated to the Flagstaff Hill Maritime Village’s museum collection by his family, illustrating this item’s level of historical value. The George Roper is considered historically and archaeologically significant and as such, is listed on the Victorian Heritage Database, VHR S286. It is an example of a vessel built specifically for fast travel to and from Australia with a large shipment of cargo. The George Roper’s cargo of steel rails adds to the historical significance of international trade to the growing colony of Australia and Victoria in particular, with rail transportation soon to become a faster and safer form of transportation between colonial towns. Divers can still access parts of the scattered wreck and other artefacts recovered in the 1970s and 1980s can be viewed in both public and private collections. Cover; unglazed white ceramic, oval shape. The cover has holes randomly poked through its surface, one large hole is a six pointed star shape. Underneath there is a narrow rim placed slightly inside the edge. There is residue on the underneath around the holes. There is orange-brown discolouration and areas where the surface is lighter coloured. flagstaff hill, warrnambool, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, john chance, west coast trader, george roper, w. h. potter & sons, w.t. dickson and son, captain john ward, russell stourbridge bricks, port phillip heads, lonsdale reef, dive wreck, vhr s286, coastal trader, ceramic, vintage, ventilated cover, domestic item -
Ambulance Victoria Museum
Humidicrib, hand made, Circa 1950s
This wooden humidicrib came from Cobram ambulance station which was part of the old Goulburn Valley Ambulance Service. When the need for humidicribs was understood, none were available at Cobram. Not prepared to wait for a humidicrib to be issued to them, local ambulance officers made their own! If you look carefully you will see the air circulation vents and springs between the inner and outer timber boxes. These were designed to make what could be a long ride over rough roads as comfortable as possible for sick babies. Probably made in the 1950s, we do not know how many babies were saved by this particular humidicrib - but it was a success. Other ambulance services made their own after hearing about the Cobram Ambulance Station humidicrib. Source Chas Martin AHSV curator). Humidicribs are used to transport sick babies from small hospitals to major hospitals for specialist care. They work by maintaining normal body temperature and provide oxygen if needed during ambulance transit. Known by a variety of commercial names, earlier humidicribs were ones heated with water bottles. Not part of an ambulances standard equipment, humidicribs are kept in ambulance stations and carried if babies needed to be transported. In the early days before humidicribs came into use and when air ambulances did not exist, many more babies died during emergency transits than do today. A doll was sourced from St Vincent de Paul Brighton. The doll was dressed in an original hand made christening gown made in 1975 by Miss Molly Hambly from Glen Waverley (now deceased). It was used for her Great Nephew's christening in 1976.

Coolidge X-ray Tube
The investigation of the x-ray appears early on to have been a priority research topic at the University of Melbourne’s School of Physics. This interest was sparked by the appointment in 1889 of Professor T.R. Lyle. Lyle, who was head of the school until 1915, is thought to have been the first person in Australia to have taken an x-ray photograph. A copy of this photograph can be found in the School of Physics Archive. For this particular experiment Lyle actually made his own x-ray tube. His successor, Professor Laby, continued to work with x-rays. During the 1920s Laby worked on the x-ray spectra of atoms and in 1930 he co-published with Dr. C.E. Eddy, Quantitative Analysis by X-Ray Spectroscopy. Also with Eddy, Laby produced the landmark paper Sensitivity of Atomic Analysis by X-rays. Laby went on to have an x-ray spectrograph of his own design manufactured by Adam Hilger Ltd. (see cat. No. 38). School of Physics, the University of Melbourne Cat. No. 22. Jacqueline Eager Student Projects Placement, Cultural Collections 2005 In 1913 Coolidge overcame the limitation of the narrow operating range of the gas X-ray tubes with the invention of the vacuum X-ray tube. A filament heated by an electric current directly releases electrons by thermionic emission. In thermionic emission, electrons are emitted from a metal surface directly by the application of an electric current to heat a wire filament. The electrons accelerate to the anode and produce X-rays. The anode has associated cooling fins due to the high temperatures attained by the release of kinetic energy by the electrons on colliding with the anode. Internal Glass sleeve: “A941/L2593/2821” -
