Abstract
Abstract A method of making jewelry wherein a substrate such as brass is electroplated with copper for adhesively receiving decorative bounded areas of vitreous enamel. The enamel in these areas is formed by applying glass frit and then firing the frit to form an enameled layer. Other bounded areas of the metal plating are covered with lacquer. The areas of vitreous enamel and lacquer are used as masks for deplating the exposed areas of the plated copper metal from the brass substrate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
97 words
A METHOD FOR SUPPORTING A VITREOUS FILM UPON A SUBSTRATE INCLUDING THE STEPS OF: SELECTING A SUBSTRATE HAVING AN ELECTRICALLY CONDUCTIVE FACING SURFACE, ELECTROPLATING SAID FACING SURFACE WITH A METAL LAYER FOR ADHERENCE OF A VITREOUS FILM, FORMING A BOUNDED AREA OF VITREOUS FILM UPON THE ELECTROPLATED METAL LAYER, AND ELECTRICALLY DEPLATING ONLY THE EXPOSED AREA OF THE PLATED METAL LAYER FROM THE SUBSTRATE BY USING THE BOUNDED AREA OF THE VITREOUS FILM AS A MASK TO THEREBY EXPOSE AREAS OF SAID CONDUCTIVE FACING SURFACE DISTINCT FROM SAID BOUNDED AREAS OF VITREOUS FILM, SAID ELECTRICALLY DEPLATING INCLUDING
Claim 2
Independent Claim
97 words
A METHOD FOR SUPPORTING A VITREOUS FILM UPON A SUBSTRATE INCLUDING THE STEPS OF: SELECTING A SUBSTRATE HAVING AN ELECTRICALLY CONDUCTIVE FACING SURFACE, ELECTROPLATING SAID FACING SURFACE WITH A METAL LAYER FOR ADHERENCE OF A VITREOUS FILM, FORMING A BOUNDED AREA OF VITREOUS FILM UPON THE ELECTROPLATED METAL LAYER, AND ELECTRICALLY DEPLATING ONLY THE EXPOSED AREA OF THE PLATED METAL LAYER FROM THE SUBSTRATE BY USING THE BOUNDED AREA OF THE VITREOUS FILM AS A MASK TO THEREBY EXPOSE AREAS OF SAID CONDUCTIVE FACING SURFACE DISTINCT FROM SAID BOUNDED AREAS OF VITREOUS FILM, SAID ELECTRICALLY DEPLATING INCLUDING
Claim 3
Dependent Claim
18 words
The method according to claim 1 wherein said vitreous film is further defined to include fused enamel frit.
Claim 4
Dependent Claim
38 words
The method according to claim 2 including the further steps of: applying Enamel frit to a bounded area to the electroplated substrate, and firing said enamel frit in a furnace to form said bounded areas of vitreous film.
Claim 5
Dependent Claim
23 words
The method according to claim 1 wherein a plurality of discrete bounded areas of vitreous film is formed upon the electroplated metal layer.
Claim 6
Dependent Claim
42 words
The method according to claim 4 wherein fused enamel frit defines said vitreous film in at least one of said plurality of discrete bounded areas, and a lacquer film defines the vitreous film at other of said plurality of discrete bounded areas.
Claim 7
Dependent Claim
25 words
The method according to claim 1 wherein said substrate is a brass metal plate with a predetermined shape for use as an article of jewelry.
Claim 8
Dependent Claim
14 words
The method according to claim 6 wherein the electroplated metal layer is copper metal.
Claim 9
Dependent Claim
79 words
The method according to claim 1 including the further steps of submerging said substrate in a plating tank containing an aqueous salt solution of said metal layer, introducing a metal ingot of said metal layer in said plating tank and passing electric current between the substrate and the ingot by connecting the leads from an electrical current supply in such a manner that the facing surface of the substrate forms the cathode and the metal ingot forms the anode.
Claim 10
Dependent Claim
81 words
The method according to claim 8 including the further steps of immersing the substrate with the plated metal layer supporting formed bounded areas of vitreous film in a plating tank containing an aqueous salt solution of said plated metal layer, introducing an ingot of the plated metal in the plating tank, and passing electric current between the plated metal layer on the substrate and the metal ingot by using the plated surface as the anode and the ingot as the cathode.
Claim 11
Dependent Claim
32 words
The method according to claim 9 including the further steps of cleaning and polishing the deplated surface of the substrate, the bounded areas of vitreous film and the bounded areas of lacquer.
