Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A decorative tile comprising: (a) a ceramic tile blank of desired shape having a roughened surface, (b) a first layer of metal spray-deposited on the roughened surface, (c) a second layer of metal attached to the first layer and being discontinuous with the first layer, thereby defining a decorative pattern on the first layer, and (d) a transparent coating material covering the roughened surface of the tile and the two layers of metal.
Claim 2
Dependent Claim
73 words
A decorative tile comprising: (a) a ceramic tile blank of desired shape having a roughened surface, (b) a first layer of metal spray-deposited on the roughened surface, (c) a second layer of metal attached to the first layer and being discontinuous with the first layer, thereby defining a decorative pattern on the first layer, and (d) a transparent coating material covering the roughened surface of the tile and the two layers of metal.
Claim 3
Independent Claim
71 words
The method of manufacturing a decorative tile comprising the steps of: (a) roughening a surface of a ceramic tile, (b) covering the roughened surface with a sprayed metal layer, (c) attaching to the metal layer a sprayed metal lamination which is discontinuous with the metal layer thereby forming a decorative pattern on the metal layer, and (d) covering the roughened surface, the metal layer and the lamination with a transparent coating.
Claim 4
Independent Claim
71 words
The method of manufacturing a decorative tile comprising the steps of: (a) roughening a surface of a ceramic tile, (b) covering the roughened surface with a sprayed metal layer, (c) attaching to the metal layer a sprayed metal lamination which is discontinuous with the metal layer thereby forming a decorative pattern on the metal layer, and (d) covering the roughened surface, the metal layer and the lamination with a transparent coating.
Claim 5
Dependent Claim
60 words
The method according to claim 2, comprising the added steps of (a) forming a design on the sprayed metal layer, (b) covering all of the sprayed metal layer except the design area with a paste, (c) spraying the metal lamination onto the metal layer and the paste, and (d) removing the paste to expose the lamination on the design area.
Claim 6
Dependent Claim
39 words
The method according to claim 3, in which the paste is a material which is softened by hot water and is removed by immersing the tile in hot water and then subjecting it to a fluid under high pressure.
