PC-3120 GOLD COLORED WARE Decorative-utility objects such as cutlery, plates, bowls and the like are advantageously constructed of an alpha brass or an alpha nickel-silver or cupro-nickel base, an outer plated layer of gold and an intermediate plated layer of nickel. The plated object is then annealed to interdiffuse gold and nickel whereby the gold layer is hardened to give enhanced wear resistance and utility. |
