About Fused Glass

Fused glass is a term used to describe glass that has been fired (heat-processed) in a kiln at a range of high temperatures. There are three main distinctions for temperature application and the resulting effect on the glass.

Firing in the lower ranges of these temperatures 1225 degrees centigrade is called “slumping.” Firing in the middle ranges of these temperatures 1380 degrees centigrade is considered "tack fusing.” Firing the glass at the higher spectrum of this range 1480 degrees centigrade is a "full fuse.”

All of these techniques can be applied to one glass work in separate firings to add depth, relief and shape.
