Copper oxide (CuO) vs. Cuprous Oxide (Cu₂O) in ceramic applications

Copper Oxide (CuO) and Cuprous Oxide (Cu₂O) are copper-containing inorganic compounds that can be used in ceramic and glaze-related applications. Although both contain copper, they differ in oxidation state, appearance, and behavior during firing. The key difference in ceramic applications lies in their coloring function and the kiln atmosphere required to develop the desired glaze color. Understanding these differences helps ceramic manufacturers select suitable raw materials and establish appropriate glaze formulations and firing processes.
