Fracture glass
From Wikipedia, the free encyclopedia
Fracture glass refers to a sheet of glass with a pattern of irregularly shaped, thin glass wafers affixed to its surface. Louis Comfort Tiffany made use of such textured glass to represent, for example, foliage seen from a distance.
The irregular glass wafers, called "fractures," are prepared from very hot, colored molten glass, gathered at the end of a blowpipe. A large bubble is forcefully blown until the walls of the bubble rapidly stretch, cool and harden. The resulting glass bubble has paper-thin walls and is immediately shattered into shards. These hand blown shards are pressed on the surface of the molten glass sheet during the rolling process, to which they become permanently fused.
In order to cut fracture glass, the sheet may be scored on the side without fractures with a carbide glass cutter, and broken at the score line with breaker-grozier pliers.
