Fused and kiln-formed glass sculpture. Fused glass is glass that has been fired (heat-processed) in a kiln at a range of high temperatures from 593 Â°C (1,099 Â°F) to 816 Â°C (1,501 Â°F). There are 3 main distinctions for temperature application and the resulting effect on the glass.
The maximum recommended working temperature for PyrexÂ® and QuickfitÂ® glassware is 500Â°C (for short periods only). However, once the temperature exceeds 150Â°C extra special care should be taken to ensure that heating and cooling is achieved in a slow and uniform manner.
