Warm Glass

Warm glass refers to fusing, slumping, and other kiln forming glass techniques which take place in a kiln at temperatures between 1100 and 1700 degrees Fahrenheit. Many in the glass business describe 3 different types of glass work:

• Cold glass — working with glass at room temperature. Examples are stained glass, glass carving, and etching.
• Warm glass — working with a kiln at temperatures between 1100 and 1700 degrees Fahrenheit.
• Hot glass — working with a furnace at temperatures above 2000 degrees Fahrenheit. Also referred to as glass blowing.

Glass Fusion Studios employs both cold and warm glass techniques.

Fusing & Slumping

Glass fusing is the process of joining or “fusing” pieces of glass together in a kiln. When high heat is applied to glass, it will soften, and with continued use of high temperatures, the glass becomes more fluid, two or more pieces of glass will flow together and “fuse” into a single sheet or block of glass.

Glass slumping is when “fused” glass is placed on a mold, heated in a kiln a second time, when the glass softens it “slumps” into the mold to take the molds shape. Molds are typically in the shape of dishes, bowls, vases or other similar shapes.
