Recipe Details
Ingredients
copper, glass, cuprite, tenorite, wallontite
Preparation Steps
The pigment is manufactured in production areas where both glass and blue/green faience are made. It is synthesized by heating components in a furnace at constant high temperatures, approximately 900'C, resulting in a mixture of cuprorivaite, wallontite, and copper oxides (p. 186-187).

Evidence
"This colour consists mainly of cuprorivaite (CaCuSi4O10) - containing variable amounts of wallontite (CaSiO3), Cu-rich glass, and cuprite (Cu20) or tenorite (CuO) - that is heated in a furnace at constant high temperatures (around z > 900' C)."
Remarks
The production of this pigment is closely linked to the activity of specialized craftsmen, including glass-makers and metalworkers, and is often related to temple workshops in Ancient Egypt (p. 187).
