Abstract
A sheet of glass having impressed therein a grid pattern which simulates a stacked series of glass blocks joined by mortar at their joints, in which the grid pattern is confined to certain tolerances so that the sheet is temperable and at the same time creates the desired glass block appearance.
Claims17
In a sheet of glass having a top planar surface and a bottom planar surface and being provided in at least one of said planar surfaces with a pattern which simulates a plurality of glass blocks which form joints with each other at their opposing edges, the pattern comprising a first set of at least two spaced and parallel ridges or grooves extending across said at least one planar surface and a second set of at least two spaced and parallel ridges or grooves extending across the at least one said planar surface in a direction perpendicular to said first set of ridges or grooves, wherein the improvement comprises said sheet of glass is temperable and said ridges or grooves extend from said planar surface a distance less than 0.03 inches.
In the method of making a sheet of glass comprised of a top planar surface and a bottom planar surface, said method including the step of forming in at least one of said planar surfaces a plurality of grooves or ridges patterned to simulate joints between a plurality of opposing glass blocks, the improvement comprising wherein said sheet of glass is temperable and wherein said step of forming said plurality of said grooves or ridges includes forming said grooves or ridges in said planar surface so as to extend from said planar surface a distance less than 0.03 inches.
