This specimen was recovered from Mica Schist, Canada. Chalcopyrite is a copper iron sulfide mineral with a chemical composition of CuFeS2. Its name derives from the Greek words for copper (chalco-) and brass (pyrite). It can be found in shades of yellow, green and grey, and, when exposed to acid, it can change to purple, blue, violet and yellow tones. Weathering can cause loss of its metallic luster and its brass-yellow colour. Chalcopyrite forms under various conditions, with the most significant deposits being hydrothermal in their origin. It is known globally as the most important ore of copper for thousands of years, and is thus considered a very important mineral formation. Given its golden appearance, it is often confused for the mineral gold, earning it the popular reputation as 'fool's gold' or 'yellow copper'. However, it can be straightforwardly distinguished from gold; the latter is soft, with higher specific gravity and a yellow streak, whereas chalcopyrite is brittle, easily scratched by a nail, and has a greenish grey streak. Copper was the first metal that was used by people. It was discovered by the Neolithic man about 9,000 years ago and it gradually replaced stone as it was easier to be shaped. In Australia, search for copper began after the European settlement, leading to the discovery of substantial deposits, like the one at the Olympic Dam in South Australia, which is regarded as one of the largest copper deposits in the world. Chalcopyrite has been used for copper since smelting processes began approximately five thousand years ago. Although by no means rare, this the specimen of this mineral can be used to reflect a wider history of industrial uses of copper for a significant portion of human history. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A solid hand-sized copper iron sulfide mineral of brass yellow, often with an iridescent tarnish, with greenish-black streak and submetallic luster. Chalcopyrite can be formed in several ways, including crystalizing from accessory minerals in igneous rocks, or from magma or within volcano sulfide deposits. Most commonly, chalcopyrite are found in hydrothermal conditions, where it forms in hydrothermal veins. As a member of the tetragonal crystal system, it often takes the shape of tetra-headed crystals, often with striations along the sides of the crystals. #18 Copper pyrites/(chalcopyrite) in/Laurentian Slate/(page 315 of inventory)/page missing from/descriptive catalogue/ Other label: 81 /fool's gold, chalcopyrite, mineral, rock, geology, geological, hydrothermal, neolithic, european settlement, olympic dam, south australia, stone, deposits, specific gravity, greenish grey streak, brittle, mineral gold, metallic luster, cufes2, greek words

John Kennedy was born on 04 April 1862, the son of ship carpenter Robert Kennedy and his wife Florinda (Aitken), and the brother of Malcolm and Colin Kennedy. In 1860 the family migrated to Melbourne where Kennedy senior set up as a shipwright. In 1879 Malcolm and John, who trained as a naval architect, joined their father as Robert Kennedy & Sons, shipbuilders and shipsmiths. On 27 December 1883 at North Melbourne, Malcolm married Ann White with Presbyterian forms. Next year Robert Kennedy & Sons removed to Hobart where with John W. Syme and W. J. Duffy, partners until 1889, they took over the Derwent Ironworks & Engineering Co., a foundry formerly owned by the (Alexander) Clark family. The Kennedys also acquired the patent slipyard, formerly Ross's, at Battery Point. After the shipbuilding industry in Hobart began to flag John also turned to mining: he attended the Ballarat School of Mines, and reopened the Hobart smelters which had been an adjunct of the Derwent Ironworks in the 1870s. He made several voyages overseas on smelting business and as mining promoter, and was a member of the London Stock Exchange. In 1913-14 he was manager of Tongkah Compound (1910); Robert Kennedy & Sons was reputed to have contributed to the success of the Hobart-run Tongkah Harbour, Thailand, tin mines by developing a suitable dredge. The brothers also held shares in the Irrawaddy Burma Co. John was a member of the Australasian Institute of Mining Engineers and from 1932 an honorary life member of the American Institute of Mining & Metallurgical Engineers. John died in Hobart on 10 January 1937. (Ann G.

This Sikes brass hydrometer was manufactured by the optical and scientific instrument makers Kasner & Moss of 17 Collins Street West, Melbourne, in the latter part of the nineteenth century. The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. This hydrometer set was donated to Flagstaff Hill in 1979 by local wine and spirits merchants Lynch Bros of Fairy Street, Warrnambool. Giffen Russell had established the business in 1878, and Harry Lynch took it over in the 1930s, and after he passed away in 1953 Kevin Matthew Lynch became proprietor of K M Lynch Food and Liquor. The business closed in the 2010s. The hydrometer may date back to the establishment of the business in 1878, as Kasner & Moss were selling hydrometers in Melbourne from 1864. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid. This hydrometer and its fitted and hinged wooden container show signs of heavy and protracted use in a working environment. Although the instrument has some parts missing and has been recently repaired, the original quality of the inlaid box and the fine engraving on the instrument and the attachable weights, are indications of the hydrometer’s very real value when new. This Sikes hydrometer, bearing the maker's mark of “Kasner & Moss Melbourne” and the registered number “20373”, was presented to the purchasing public as a precision-made instrument designed for professional use. The Sikes hydrometer is of local significance because of its implied association with the alcohol trade in the southwest region of Victoria. It was donated by a family member of Lynch Bros, a local licensed outlet for wines and spirits in the period before the general relaxation of liquor licensing laws in the State of Victoria. It may have belonged to Griffin Russell who established the liquor store in 1878.Hydrometer; original Sikes brass hydrometer in a polished wooden case with an inlaid plaque on the lid. The brass float is a sphere with a thin flat upper stem and a short, lower stem with a bulb-shaped end. The upper stem is engraved scale on both sides with the numbers 1 to 10, and five divisions between each number. There are ten fixed pegs in the base to secure the thick brass horseshoe-shaped, numbered, various-sized weights (20, 30, 40, 80, 90); the free pegs would have originally stored another five weights (10, 50, 60, 70, and 100). The empty compartment in the box suggests another part in the initial set, probably a thermometer. The fitted, fabric-lined box has two brass closures and two brass hinges. The scientific instrument shows signs of heavy use and repairs. The Serial Number on the float matches the Serial Numbers on the weights. The plaque on the lid, the float and the weights have inscriptions. Made by Kasner & Moss, Melbourne. Plaque: “SIKES HYDROMETER / KASNER & MOSS / MELBOURNE” On float's lower stem: “SIKES 20373” On one thin edge of the float's scale, engraved in script “Kasner & Moss” and stamped “MELBOURNE”, and symbol“P” rotated 90 degrees.

This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base. The case has ten vertical pegs to secure the weights. The brass hydrometer has a spherical float and eight thick brass horseshoe-shaped weights. The serial number is on each section of the float and all weights. Both sides of the float’s upper flat stem have a scale from 0-10, with five divisions between each number. The eight weights are numbered from 20 – 90 in increments of 10. The set includes a mercury thermometer mounted on an ivory back plate labelled with Fahrenheit and Centigrade Scales. The Sikes hydrometer set was made by Loftus of London. The hydrometer model is IID 510, Serial Number is 14674, calibrated by Longs, London.
