The Crucible 18 is built with heavy insulation of 3” thick brick walls and a 1” fiber blanket surrounded by a solid stainless-steel jacket. A one-inch ceramic fiberboard gasket retains the heat in the kiln when gathering glass from the crucible and customized gaskets can be cut to the size of the crucible when the kiln is ordered. A stainless-steel trough protects the kiln brick when gathering glass and the counter-weighted lid cover makes gathering glass safe and easy. The 3” thick separate kiln bottom may be turned over or easily replaced if damaged. The Crucible 18 is equipped with an automatic lid shut-off which turns the elements off when the lid of the kiln is opened and the Bartlett Instruments KilnStar digital controller comes standard on the kiln. Type K or Type S thermocouples are available options.

For rapid heating or melting glass, more than two-element sets may be used. • Banks of elements are labeled on the electrical box – 1-3, 2-4, 5-7, and 6-8.
