ABSTRACT:
Non-toxic, non-electrolytic solutions, creams and immersion baths are provided for gold plating metallic items such as silver, copper, nickel, brass and gold alloys, as well as silver plated or gold plated items. Water soluble gold salts are used, together with reducing compounds. For convenience, the gold plating ingredients may be combined with salts to form tablets or powders. Addition of water to the tablets or powder provides the novel solutions and immersion baths. The amount of gold generating compound in the solutions and creams is selected to either replenish or maintain the amount of gold on an item which already has a gold surface.
