Krohn Tivabrite is an electrostripper and polisher for yellow gold. In most cases, it can replace bombing in a hydrogen peroxide/cyanide solution, with better results. Tivabrite gets into spots, crevices, and undercuts that are impossible to reach with a polishing buff. Tivabrite is a unique combination of chemicals that, when mixed (4 oz. to the gallon) with water and an equal weight of cyanide (sodium cyanide is preferred) and utilized with a reverse current, provides a superior polishing action and leaves yellow gold jewelry bright, clean, and polished.
