In some mills, a longitudinal shake is given to the plate instead of this side shake. Thallium is very toxic but with proper handling can be prepared. The amalgamation process, where mercury breaks golds atomic structural bonds and forms an alloy at low temperatures, also happens between it and and almost all other metals, including zinc, potassium, aluminum, and tin. Fresh mercury is then added, and brushed over the plates, which are finally smoothed with a soft brush. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. When it has become quite black, which will be in about half an hour, it is dipped into a bath of water, when the scaling can be washed off. This is made of iron, and is similar in construction to chlorination barrels, but without the lead lining.
