Structured glass, and an improved insulating glass assembly
First Claim
1. A low relief structured glass sheet having two faces, comprising, in combination, a plurality of convex curvatures, a plurality of imparted graphic lines defining the perimeter of said convex curvatures, a plurality of concavities reciprocally related to said convex curvatures, a plurality of retaining ridges being reciprocally related to said imparted graphic lines and defining the perimeters of said concavities, highly compressive glass surfaces resulting from a strengthening treatment whereby structural compressive curvatures are formed, a plurality of areas of optical distortion, extending in approximate bands away from said graphic lines, and a flat perimeter lip, said retaining ridges being in a substantially planar alignment with each other and with said perimeter lip.

Abstract
An improved insulating glass assembly incorporates an articulated low relief structured glass sheet as one or both external faces of the assembly. The low relief structured glass sheet is composed of a formation of external convex curvatures and a corresponding array of internal concavities, defined and separated by a plurality of imparted graphic lines and a corresponding plurality of internal retaining ridges. Unique optical effects are intrinsic to the structured glass sheet. The disclosure includes the mold apparatus for manufacturing low relief structured glass sheets.

- 7. An improved insulating glass assembly wherein two sheets of glass are held apart by a spacer element and sealed with a sealing element to create an insulating air space therebetween, wherein the improvement includes an external low relief structured glass sheet comprising, in combination, a plurality of external convex curvatures, a plurality of imparted graphic lines defining the perimeter of said convex curvatures, a plurality of areas of optical distortion, extending in approximate bands away from said graphic lines, a plurality of interior concavities reciprocally related to said convex curvatures, highly compressive glass surfaces resulting from a strengthening treatment, a plurality of retaining ridges being reciprocally related to said imparted graphic lines and defining the perimeters of said concavities, and a flat perimeter lip, said retaining ridges being in a substantially planar alignment with one another and with said perimeter lip, whereby increased air space is held within compartmentalized concavities formed by said retaining ridges in a manner which restricts internal convection currents within the insulating glass assembly.
