Ceramics Uses Copper Oxide

Description

Copper Oxide is an inorganic substance. The Copper Oxide formula is CuO. The density of CuO is 6.31g/cm³. Cuprous Oxide contributes to the production of enamels, glazes, and paints.

Black Cuprous Oxide (CuO) is a dark gray powder. And it can make a colorant in glazes and glaze preparations. It acts as a flux and creates a liquid glaze. Black CuO can also be prepared as a detergent for brushing onto bisque ware. It usually produces a green color during oxidation, while its reduced form is red. The reason why Copper Oxide is more oxidizing is that it contains more copper than copper carbonate.

How to use Copper Oxide powder in ceramics?

Copper Oxide powder is a pigment that imparts green, blue,  or red hues in ceramics, glazes, and enamels. Under normal oxidation conditions, CuO molecules remain unchanged and produce a clear green color in oxidized glazes. Copper Oxide produces blood and fire reds when burned in a reducing atmosphere, in which case it becomes Cu2O. Copper Oxide, also known as tenorite mineral, is a colorant in ceramics and in the production of enamel frits to increase surface adhesion. In addition, it is a strong flux, and even 2% can significantly improve the melt flow of glazes.
