Diggers & Mining. Diggers and miners. Walhalla - Gold Town. A gold rush occurred, and almost immediately a rich reef called Cohen's Reef was discovered. Mining companies were formed to work the reef, and in 1864 the batteries were crushing profitable ore. Markings: 12 995 WAL. Used as a teaching aid.hanimounteducation, tertiary, goldfields

Ore bearing rock brought out of the mine was crushed at the battery by heavy metal stampers and the fine material passed over copper pates coated with mercury. Gold particles would combine with the mercury forming an amalgam which was then scrapped off the copper plates and put into the amalgam bucket ready for retorting too extract the gold. The amalgam of mercury and gold was placed into the retort which was heated to evaporate the mercury. The mercury cooled as it ran down the pipe which was recovered to be reused leaving the gold behind. The gold would later be put into a crucible and heated to burn of impurities and the molten pure gold poured into an ingot.A heavy cast iron bucket 20 centimetres high, 16 centimetres in diameter at its base and 22 centimetres diameter at the top. It has a spout five centimetres wide protruding two centimetres. There is a handle which is a semi- circular shape 19 centimetre wide extending 14 centimetres above the bucket The inside of the bucket has an enamel coating. amalgam bucket, bendigo gold, gold retort

Cast iron dolly pots were used in the mining industry to crush ore specimens and samples into dust before panning. The principle is the same as a mortar and pestle.This item has two pieces both are made from cast iron and are rusted and a dark brown color. One is a tapering cylinder 16.5 centimetres wide a its top, the first two and a half centimetres down tapper to 13.5 diameter, the next nine centimetres tapper to 11 centimetres diameter. the last two and a half centimetres is a solid base that flares out to a 16.5 centimetre diameter, the inside of the bottom of the cylinder is a bowl shape. The other piece is a solid tapering shape, it's four and a half centimetres in diameter at one end which tappers to three centimetres in four centimetres of length, the next sixteen centimetres tapper to two centimetre diameter. There is a knob on top, one and a half centimetre high and two and a half centimetres wide.mortar and pestle, dolly pot, gold minning

Cast Iron lace was made in foundries in most cities. There were 42 such foundries in Melbourne alone. It was cheaper to make than wrought iron. "Pig iron", iron ore was melted in a blast furnace, mixed with alloys and then poured into molds usually made of sand. The alloys needed a minimum of 2% carbon.A black and white photograph by Alan Doney of the building at 247 View St in Bendigo. The photo shows detail of the wrought iron on the verandah. alan doney, bendigo, wrought iron
