Troy ounces are slightly heavier than avoirdupois ounces that we commonly use. 1 troy ounce equals roughly 1 1/8 ounces and is used for the weighing of precious metals and gems. It is believed that the troy ounce dates back to the 16th century to the town of Troyes in Frances. This was a major trading centre for Europe and a standardised for of weights was needed. One troy ounce equalled 480 grains of barley.Two Sets of Troy weights all circular and tapering to the bottom plus two individual weights - 1oz.

Gold bearing ore is pulverized by cast iron stampers (steam driven) and material then passes over a large copper plate covered in mercury causing the gold particles to combine with the mercury to form an amalgam which is scraped of and placed in a retort. The retort is heated causing the mercury to evaporate leaving the gold to be refined into ingots. The mercury is cooled as it leaves the retort and is reused. A second tray covered in what is called a blanket traps any fine gold that has passed the first plate. Finally the residue material goes over a vibrating table called a Wilfley Table which captures any iron pyrites which may contain about three percent gold. this is roasted and treated to recover any remaining gold at a special treatment plant.Wooden model of a five heads gold stamper battery.

Electro hydraulic dredge Snake Valley 1909. J Mc Bennett, was an engineer back at the main base, at Dawson's dam on the Carngham Road, Between Linton and Snake Valley. These dredges were used for getting gold. The streams of water under high pressure just washed the hills and ground away. This dredge closed down early 1910. 200 H.P. motors were used and 10 in. pumps.Black and white image of three workmen, one beside mining building the other two at dredge pump outlet. Image mounted on dark brown card. Between 1904 and 1911 the Electro Hydraulic Company sought to extract gold in an area north of Linton known as the Hard Hills. By blasting water from high-pressure hoses into the hillsides, soil containing gold was washed out for sluicing. Two gravel pumps in Dawson's Dam pumped the wash through the sluices. Despite considerable investment in expensive equipment, the Company did not have a great deal of success, and the mining operation ceased in 1911.mining, gold, mining equipment, electro hydraulic dredge, dredging, sluicing, dawson's dam, snake valley, miners

This coat was produced from wool first shorn in c.1928. 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 South Australian 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 and a text panel used by Elders were also donated at the same time.Coat, brown wool.
