Cobalt Oxide is a reliable, stable, black powdered oxide. In small amounts it produces consistently intense blue tones. Used as a glaze colorant and brushing oxide decoration. 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. Cobalt Oxide is more likely to create blue specks than Cobalt Carbonate which is more finely powdered. With the proper proportions and formulas, additional colors and effects can be achieved using Cobalt Oxide.

NOTE: In its powdered form, Cobalt oxide can be very hazardous if ingested and can cause skin, eye and/or respiratory system irritation. Please use proper precautions, including protective coverings, when working with this substance. If inappropriate contact does occur, seek medical attention immediately.
