Product Information: 
Red oxide of copper formula is Cu2O
Red copper is a reduced form of the normal black copper oxide (CuO). In normal oxidizing firings it will transform to the cupric oxide form (CuO) to produce the normal green coloration in glazes and glass. If fired in reduction, it will maintain its Cu2O structure to produce the typical copper red color.
Red copper oxide is usually surface coated to prevent oxidation. For this reason, it may be very difficult to get the material to mix with a glaze slurry. If so you must soak the material in alchohol to wash the surface. Or use soapy water and then rinse with clean water (so there is no soap in the glaze slurry).

Manufacture process: 
Pyrometallurigical process: copper(I) oxide is formed when copper powder is heated above 1030 deg C in air; Hydrometallurgical process: tetraaminedicopper(I) sulfate prepared by leaching an excess of copper with a solution of ammonia and ammonia sulfate, with air as the oxidant, yields a red copper(I) oxide upon acidification to pH 3-5; electrolytic production of copper(I) oxide between copper electrodes in brine yields a yellow product at room temperature.
