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.
3.Laminate.Laminate the glass with PVB film.PVB should be about 5mm larger than glass. 4.Rolling.There'e 2 stage. The first stage include heating oven and rollers to emilinate the air between film and glass.Distance between roller is 90% that of glass total thickness and with0.25-0.5mpa pressure,after this stage,glass temperature is about 30-40âã
