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. (http://en.wikipedia.org/wiki/Bioscope_show) The Projector was a rather unreliable piece of apparatus, powered by a variety of light sources, including Calcium Oxide (Lime-Light). A Calcium Carbide Burner, or the rather more superior Carbon Arc. All these methods were highly unpredictable & quite frankly...dangerous! Often resulting in explosions, burning down the entire Show!
