Cast Slumped Glass by Experience Glass, San Diego, California

Slumped glass, most commonly known as “cast glass” because it shares similarities with glass casting process, is in actuality a thermoformed glass. Textures, patterns and custom designs are kiln-formed through heating and then "slumping" the glass panels onto or over a mold.

To produce a custom piece of slumped glass, the glass is cut to dimensions that approximate the shape of the mold and then placed on top of it before the kiln is heated.

The kiln temperature typically starts to climb at quite a rapid rate until the glass is in a flexible "orange state", at which point gravity will allow the glass to slump into the mold (hence the name "slumped glass"). The peak temperature is then held constant for what is known as the "soak". The kiln is then allowed to cool slowly so that the slumped glass can anneal before it is removed from the kiln.

When more than one color of glass are used in the same piece, they must have the same CoE (Coefficient of Thermal Expansion) to prevent fractures caused by the glass shrinking at differing rates. Use of proper materials and setup allows cooling to remain uniform, and ensures that no tension builds up as the slumped glass cools.

All of our molds are made in house, and our textures and patterns are Gomolka Design originals.
