Rosarita Slag Glass Cabochon

Rosarita is a unique material, which derives its exceptionally rich, red color from the process of gold refining. It is a unique by-product of the 1960s and 1970s gold refining processes. Alaskan beach sand was smelted for its gold content and the slag by-product was Rosarita, which is essentially a gold-infused glass. The base material for Rosarita is silica (which is quartz particles) mixed with gold at high temperatures.
