How is glass fused in a kiln?
After cut or nipped pieces of compatible glass are assembled, the project is placed in a kiln. The kiln will heat the glass slowly from room temperature up to fusing temperatures (1300-1500 Fahrenheit) and slowly back down again according to the Firing Program or Schedule selected.
What is the difference between ceramic and kiln fired glass?
Kiln-fired glass, or warm glass as it is also called, is typically done in an electric kiln at temperatures lower than ceramic temperatures. 1300-1500 degrees F is typical. For reference, Cone 04 is about 1900 degrees F and Cone 10 is about 2350. Because of the lower temperatures involved, all ceramic kilns are capable of firing glass.
When do you need a glass kiln?
The simple answer is we need to use a kiln when we want to fuse, slump, polish, mold, and melt glass. The most common usage of kilns is for fusing and slumping. Glass Kilns are of many types such as microwave glass kilns, electric kilns, stainless steel kilns, ceramic kilns, craft kilns, traditional kilns, and professional glass fusing kilns.
Does glass release fumes when firing?
Glass does not release fumes when fired. Most glass artists actually do NOT vent their kilns because of the risk of thermal shock. Thermal shock happens when glass cools too quickly, which can cause it to crack or even break. Because of my ceramics background, I still choose to vent my kiln when firing glass.
