One of the oldest colorants used by potters. It is a popular source of copper in glazes and glass. The oxide form of copper can give a speckled color in glazes whereas the carbonate form will give a more uniform effect. Copper normally produces green colors in amounts to 5% where it moves toward black. In reduction firing, it turns to Cu2O and gives vibrant red hues. It the glaze is fluid copper will tend to crystallize heavily. See CuO and Cu2O in the oxides database for more information.
