Fused Light Studio glass is kilnformed, or "warm" glass. This means that the glass is cast, carved, fused or shaped in a kiln, at temperatures of 1200 to 1650 degrees Fahrenheit. 
The glass must then be annealed - cooling at a slow, even rate so that the glass remains stable. The kiln firing on smaller pieces takes two to five days; large castings take a week, a month, or more.

To create figures, textures, and shapes, you can sculpt in clay, wax, ceramic fiber felt, or sand.

Cast glass uses a plaster mold, made from a clay or wax form.

Glass cast for Still Standing

A piece might start from a single thought, or from a life story. 
The artist may first sketch designs expressing that thought or story, then consider how to use glass to carry out the design. 
We do studies in clay or glass to test the methods and see how the design translates to glass.

Glass artists can also design by sketching or sculpting directly in the sand, clay or fiber felt from an emotion or idea. 
Or they might arrange glass pieces to see what they elicit, and rearrange as a concept emerges. 

Glass shards arranged and layered for The Waterfall

For the base of standing sculptures, some are sculpted from clay, others are a separately cast piece of glass.
With framed pieces of clear glass, the artist may paint or digitally create a background to bring out the depth and texture of the glass.

Almost all glass requires finishing work to smooth and polish the edges. This can take as long as making the piece itself.
