Product Description:
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.
It can also be added to porcelain or stoneware clay. Because cobalt oxide is not as finely powdered as cobalt carbonate, cobalt oxide is more likely to create blue specks, a quality that we believe can be quite beautiful!
Because of the strength of this oxide as a colorant, glazes containing cobalt can produce halos and flashing during firings.
