Quick Overview

What is a Crucible Kiln?


Olympic Kilns introduces the Crucible 18 for hot glass. The Crucible 18 is built with heavy insulation consisting of 3” thick brick walls and 1” fiber blanket surrounded by a solid stainless steel jacket. A 1” ceramic fiberboard gasket retains the heat in the kiln when gathering glass from the crucible. When ordering, customized gasket openings can be cut to the size of the crucible which will be used.


The 3” thick separate kiln bottom may be turned over or easily replaced if damaged. The kiln is built with a counter weighted lid cover making gathering glass safe and easy.


The counter weighted cover lifts to reveal the opening in the lid. A stainless steel trough on the lid directs glass back into the crucible minimizing lid damage.


Four (4) sets of elements can be used for rapid heat up. Two (2) sets are required to maintain temperature, two (2) sets in reserve to prevent unwanted cooling if an element is lost while firing. The Crucible 18 is equipped with an automatic lid shut-off which shuts the elements off when the lid of the kiln is opened, a Bartlett 3 Key electronic controller with four ramp/hold programs, and a Type K or Type S thermocouple may be chosen when ordering .
