Cobalt Oxide and Cobalt Carbonate . Cobalt is an extremely powerful colorant that almost always produces an intense blue. Cobalt carbonate tends to be used more by potters because it has a finer particle size and is less intense. In glazes with a high magnesia content, very small amounts of cobalt can give a range from pink through blue …
