Cobalt Carbonate
Cobalt oxide and cobalt carbonate are ceramic raw materials. They are frequently found in glaze and slip formulas contributing, under varied circumstances, a light to dark blue colour depending on the added amount. Cobalt has traditionally been used as a decorative blue colorant in everything from Chinese porcelain to American salt glazed stoneware. Deposits of cobalt are currently mined in Canada and Southern Africa. It is extracted as a by-product of nickel ore mining. Cobalt carbonates (CoC03) and the stronger cobalt oxide (Co02)
