Crucible 18 equipped with electronic controller Model – Crucible 18/240 or 208 volt
Inside dimensions: 17.5 ” wide x 18″ deep, fires to 2350° F
The model comes with an 8” stand, counter-weighted cover, operating instructions, and a One-year warranty.
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.
Element Operation: Four (4) sets of elements can be used for rapid heat-up. Two (2) sets are required to maintain temperature, two (2) sets are in reserve to prevent unwanted cooling if an element is lost while firing. 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.
Key Features

Automatic Lid Shut-Off — Elements automatically de-energize the moment the lid is opened — a critical safety feature when gathering glass
4-Bank Element System — Four element sets (banked 1-3, 2-4, 5-7, 6-8) for rapid heat-up, with two sets in reserve to prevent unwanted cooling if an element fails mid-firing
Counter-Weighted Lid Cover — Makes gathering glass from the crucible safe and easy, even during long sessions
Stainless Steel Gathering Trough — Protects the kiln brick from wear during repeated glass gathering
Customized Crucible Gaskets Available — One-inch ceramic fiberboard gaskets cut to the exact size of your crucible at time of order
Reversible/Replaceable Bottom — 3″-thick separate kiln bottom can be flipped or swapped if damaged, without replacing the whole kiln
