When the acid is almost completely neutralised, the lye is removed, concentrated and poured into milk of lime. Bismuth xide is thus precipitated and calcium nitrate remains in solution 2Bi(NO 3) 3 + 3Ca(OH) 2 = Bi 2 O 3 + 3Ca(NO 3) 2 + 3H 2 O This process is used mainly for the production of salts of bismuth.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

The actual size of each tile is 6cm x 10cm. Firing time was 3 minutes at 1472F. The copper groundcoat can be used to give an off-white base on which to apply wet process colours. Higher and longer firing of wet process enamels on copper gives very interesting results as the tile colours become tinted with chemicals in the copper base.
