Cobalt carbonate has a lower cobalt content than cobalt oxide and so a higher concentration is required to achieve the same colour. However, it is easier to mix evenly and melts easier.

1-3% carbonate produces deep blues in leadless glazes, or a blue-black in lead glazes, or a vivid blue in alkaline glazes. The presence of magnesium gives a more purple tint.
