  • Patent number: 5006207
    Abstract: An ornamental design is defined sharply on an expansive surface of a faucet spout by providing an initial finish on the expansive surface, the initial finish contrasting in color with what is beneath the initial finish, causing a mask to adhere to selected portions of the expansive surface, by means of a pressure-sensitive adhesive, and treating unmasked portions of the expansive surface so as to cause the unmasked portions to contrast in color with the initial finish when the mask is removed. Treating includes etching the unmasked portions, blasting the unmasked portions with a liquid jet, blasting the unmasked portions with abrasive particles in a gas stream, or blasting the unmasked portions with abrasive particles in a liquid stream. Thus, an ultimate plating layer can be so removed from the unmasked portions, so as to expose a penultimate plating layer contrasting in color with the ultimate plating layer.
