Cut glass panel

A decorative self-supporting cut glass panel adapted to be mounted with its periphery encompassed in a frame in a window, door, or the like, comprising, in combination,

• a. a plurality of pieces of light-transmitting sheet glass bonded together in coplanar relation forming a self-supporting and light-transmitting panel having a decorative side and a reverse side,
• b. the peripheral edges of each of said glass pieces which are adjacent others of said pieces in said panel being cut to approximately the mirror image of said adjacent pieces and being arranged with spaces of approximately uniform width between adjacent said pieces,
• c. adhesive material filling said spaces between adjacent said pieces of glass,
• d. said adhesive being a mixture of organic materials and inorganic filler,
• e. said filler having a coefficient of thermal expansion closely approximating that of said glass pieces and being selected from the group consisting of finely ground glass, magnesium oxide and calcium carbonate,
• f. said mixture of organic materials comprising an epoxy resin and a curing agent,
• g. said adjacent edges of said glass pieces being beveled on said decorative side of said panel,
• h. said bevel being at an angle in the range of 5.degree. to 17.degree. from the plane of said decorative side of said panel and having a width of the order of 5/8 inch,
• i. the edges of said glass pieces facing each other having structurally irregular surfaces providing better bonding engagement with said adhesive material,
• j. said adhesive material extending through said panel between adjacent pieces of glass and having a generally T-shaped cross-section including a head portion overlying the adjacent surface portions of said bevels but retained within the plane of said decorative surface, and
• k. the end of said T-shaped section opposite said head portion being flush with said reverse side of said panel.
