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.Four circular Troy weights - three have raised outer edge/lip with weight details imprinted in the centre.

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.
