Cobalt oxide is a consistent, reliable oxide and a common colorant in pottery. It is available in powdered form and is blackish in color. It is a very strong oxide, and using very small quantities yields bright, intense blues. In ceramics, cobalt oxide is used mainly in slips, washes and glazes and can be applied through brushwork, decals or other surface decorating techniques.
