Abstract
Abstract A bevelled glass assembly and method of making is disclosed. A sheet of annealed glass has at least one groove ground on one surface. At least one other groove intersects the first groove. Both grooves define an array of parallel striations. The sheet of glass is then tempered. The sheet of glass is normally surrounded by a frame.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
A bevelled glass assembly comprising, a sheet of annealed glass having opposed surfaces, at least one first longitudinally extending groove ground into one surface of said annealed glass sheet, said longitudinally extending groove having an array of parallel surface striations, at least one second longitudinally extending groove intersecting said first groove, said second intersecting groove having an array of parallel surface striations, said sheet of glass being tempered and wherein said parallel surface striations of said grooves enhance optical reflections.
Claim 2
Dependent Claim
80 words
A bevelled glass assembly comprising, a sheet of annealed glass having opposed surfaces, at least one first longitudinally extending groove ground into one surface of said annealed glass sheet, said longitudinally extending groove having an array of parallel surface striations, at least one second longitudinally extending groove intersecting said first groove, said second intersecting groove having an array of parallel surface striations, said sheet of glass being tempered and wherein said parallel surface striations of said grooves enhance optical reflections.
Claim 3
Dependent Claim
24 words
A bevelled glass assembly according to claim 1, wherein a plurality of first longitudinally extending grooves are ground into said surface of said sheet.
Claim 4
Dependent Claim
15 words
