Abstract
This invention is directed to an electroless method of antiquing a zinc or pewter component and to products produced using the method. In its simplest form, the method includes: contacting the metal component with an oxidizing solution; rinsing the metal component to stop the formation of additional oxide; and buffing the component to achieve the desired antique look. In a preferred form of the invention, the oxidizing solution includes copper chloride, selenious acid, hydrochloric acid and sodium tetradecyl sulfate. The preferred method further includes various cleaning, rinsing and drying steps, as well as the application of a protective lacquer or other coating to seal the oxide formed on the metal component.
