ABSTRACT:
A process for imparting a simulated patina appearance to a copper substrate including selecting a colorant having the desired initial patina color tone and producing a noncontinuous layer of the colorant on a surface of the copper substrate to provide the appearance of patination of the desired tone via interspersed spots of the colorant. The remaining portion of the substrate is exposed for natural patination.
