Description
Luminar Glass Containment Molds are unique molds made from Luminar Fusing Sheet (ZRCI RS-100). These rounded rectangular forms are composed of a reinforced structural alumina composite material, heat treated to enhance mechanical and thermal properties. These molds are ideal for slumping and fusing projects to 860°C(1550°F) and can be used up to 1260°C(2300°F) as a electrical and thermal barrier. It has a smooth burnished surface that glass will not stick to. It is lighter than other fully dense kiln shelf materials and allows for rapid heating and cooling cycles. Luminar Fusing Sheets can be fired repeatedly (its tan color will turn white on first firing) and can be cut to the desired size with standard saws or other common tool. To prevent warping or slumping of the sheet when firing heavy loads, some support should be provided from below. It is available in several depths. Luminar glass containment molds are inorganic, non-flammable and contains no asbestos. Its high Al2O3 content makes it highly resistant to many environments, including molten glass and bronze.
