Appearance Colour: Pinkish Red
Form: Powder, Inorganic Compound
- In Slips: 2%-8%

Stability: Relatively stable in comparison to other colourants & opacifiers
Additional Information: Red copper oxide (Cu2O) is a reddish powder that is a reduced form of black copper oxide that produced by heat-treating the black form. Red copper oxide has a low solubility in water and beads up at the surface of a solution, which makes it difficult to work with at times.
Caution: In its powdered form, red copper oxide is harmful if swallowed and a potential skin and respiratory tract irritant. Please use protective coverings when handling this substance.
