Document - Archbold's Gold Treatment Works, Robert J. Kaufman, LRGM Services, 15th June, 2002
... fire assays... are described, including: fire assays, crushing, retorting and smelting...-report fire assays crushing retorting and smelting refining ...The Archbold (Chewton) Gold Treatment Works was erected c.1884 by Jeremiah Archbold who operated an assay and metallurgical business specialising in the treatment of gold-bearing ore. The battery, furnaces and Chilean mills which survive on the site suggest that the chlorination process was used to assay pyritic ore. The works subsequently incorporated the cyanide process after its introduction to Victoria in the late 1890s. Upon Jeremiah's death in 1917, the works continued to be run by one of his sons, Herbert. Herbert Archbold went on to become widely known throughout Victoria for his cyaniding expertise. Herbert died in 1966 and the property was bought by his son Harry. When Harry Archbold died in the late 1980s the treatment works was closed and everything left as it was. https://vhd.heritagecouncil.vic.gov.au/places/7899/download-reportNineteen page document.

... are used in the fire assay process due to their ability... in a mining site. Stoneware crucibles are used in the fire assay ...Assay is a process of metallurgy and chemical analysis used to determine proportions of precious metals in ores and other metallurgy substances such as silver or gold. The process helps identify pollutants present within a sample and can indicate a high level of pollution in a mining site. Stoneware crucibles are used in the fire assay process due to their ability to withstand high temperatures. Fire assay is a three step process where by samples from the mine are ground in a find powder and then mixed with dry powder chemicals. This mixture is heated in a crucible to extreme temperatures (crucible fusion) until all of the powers fuse into a glass like slag. Once this reaction is complete, the contents are poured into a mold and cooled. In step three (known as cupellation) the mixture is separated in a fire assay cupel and once this is complete the cupel with reveal a small bead of precious metals. Established by George Guthrie in 1857 (about 5km north of its current site) and then again seven years later in 1864 after it initially closed, Bendigo Pottery remains one of the most influential and longest running potteries in Australia. Over the years the Pottery has contributed to the growth and development of the district through both its products including building products, table ware and decorative and commemorative war as well as artistically, being responsible for training and supporting many potters locally. It has partnered with the City on various tourism promotions and the Civic Collection holds a number of important items within its collection.Two stoneware vessels of differing dimensions (0287.1 & .2).

Functional object - Silver Vesta Case, David & Lionel Spiers, 1885
Vesta cases, also known as match safes, are small boxes that are used to carry matches and keep them safe from the elements. In the early 1800's, it was common to carry matches, since some type of portable fire was needed to light lanterns and stoves. The matches of that day were crude compared to today's standards, and were known to light when making contact with each other, and sometimes even spontaneously. In order to alleviate this potentially hazardous situation, it made good sense to utilize a Vesta case or match safe. One of the more interesting features of the vesta case or match safes is that they almost always include some type of rough or ribbed surface, usually on the bottom of the case that is used for striking the matches. This vesta case is a portable pocket vesta. These cases take their name from the virgin Roman goddess of fire, home, hearth and family. Usually Vesta was depicted as the fire in her temple. Only Vestals (her priestesses) were allowed into her temple. Her association with fire made her name the natural choice for British companies that manufactured matches. The hallmarking of sterling silver is based on a combination of marks that makes possible the identification of origin and age. The town mark identifies the Assay Office where the item was verified. The town mark on this piece is an anchor, so it is from Birmingham, England. The lion passant certifies the silver quality, as at least 925. The maker's mark, identifying the silversmith presenting the piece to the assay office is D&LS for David and Lionel Spiers. The date letter identifies the year the piece was verified, this item was verified in 1885. Lionel Spiers was a significant figure in the Jewellery Quarter and in 1906 was chairman of the Jewellers and Silversmiths Association. The item also has NHILL 1928 engraved on the front, this is likely a recent addition to the piece. Nhill is a town in Victoria so it could be that the previous owner lived here or it was gifted in commemoration. The social history objects held in the Burke Museum's collection help to tell the stories of Beechworth's past by showing the social, cultural, and economic aspects of the town's history.Silver vesta case with ribbed strike plate at the end and an etched design.

The matches of that day were crude compared to today's standards, and were known to light when making contact with each other, and sometimes even spontaneously.

One of the more interesting features of the vesta case or match safes is that they almost always include some type of rough or ribbed surface, usually on the bottom of the case that is used for striking the matches. This vesta case is the portable pocket vesta which also has a bale (ring) near the hinge so that they can be suspended from a chain. These cases take their name from the virgin Roman goddess of fire, home, hearth and family. Usually Vesta was depicted as the fire in her temple. Only Vestals (her priestesses) were allowed into her temple. Her association with fire made her name the natural choice for British companies that manufactured matches. The hallmarking of sterling silver is based on a combination of marks that makes possible the identification of origin and age. The town mark identifies the Assay Office where the item was verified. The town mark on this piece, three wheat sheaves and a sword identify Chester, in Cheshire, England as the town of creation. The lion passant guardant certifies the silver quality, as between 925 and 1000. The maker's mark, identifying the silversmith presenting the piece to the assay office is W.N. for William Neale. The date letter identifies the year the piece was verified, this case being verified in 1903. William Neale and Sons was a firm was established by William Neale in 1850 in Birmingham. His mark was entered at the Birmingham assay office in April 1862 and in the Chester assay office in September 1882. The social history objects held in the Burke Museum's collection help to tell the stories of Beechworth's past by showing the social, cultural, and economic aspects of the town's history.A silver vesta case with a ribbed strike plate at the end, a ring to attach the case to a chain and a cover that can be pushed up to open.

Book - Diary, John Kennedy, John Kennedy's Ballarat School of Mines Lecture Notes, 1889
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.
