A trademark of W.P. Dawson Inc. for a mechanical control designed to cut off electricity to a kiln when a desired temperature has been reached. At that temperature the pyrometric cones placed in the Kiln-Sitter bends, or, in digital versions, a touch-pad is used to program the firing of the kiln. As an additional safety feature, every Kiln-Sitter also has a timer that shuts off power to the kiln when the time set by the operator has past.
