Fused Glass is a glass that has been heat-processed in a kiln at a range of high temperatures from 593 °C to 816 °C.
There are three main distinctions for temperature application and the resulting effect on the glass:
- Slumping – Firing in the lower ranges – 593-677°C
- Tack Fusing – Firing in the middle ranges – 677 – 732 °C
- Full Fuse – Firing the glass at the higher spectrum of this range – 732 – 816 °C
All of these techniques can be applied to one glass work in separate firings to add depth, relief and shape.
