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 sand and cullet must be heated to their melting point to make glass. This means glass makers need a furnace that can produce temperatures over 2,900 Â° F! When the sand and cullet melt, a red-hot glowing liquid is formed. This is glass in its purest form. Long, long ago, glass was made by hand.
