About Copper (II) Oxide. Copper Oxide (CuO) is a highly insoluble thermally stable copper source suitable for glass, optic and ceramic applications. Copper oxide is a black solid known as tenorite in mineral form, it can be formed by heating copper in the presence of oxygen. Oxide compounds are not conductive to electricity.
