Description

Three 9” high sections stack on top of each other. The hinge and element connection box hold the entire kiln together as an integrated unit. The kiln is very easy to assemble and disassemble. All wires are marked or color coded and attach to pull-off terminal strips.  More about sectional construction...
Stainless steel wrapped around shaped firebrick. There are three adjustable clamps welded to each casing. All assembly is with stainless steel screws. The kiln sections sit on a separate stand.
Spring loaded "Easy-Lift" lid opens with a feather-lite touch. The strength of the hinge allows the lid to rest back away from the opening without a support arm that would get in the way of loading the kiln.
Heavy-duty 14 gauge full solid stand with multiple bends for strength. Legs bolt on with heavy 1/4-20 stainless bolts. The metal is aluminized for good corrosion resistance.
A proprietary brick coating is applied to all interior surfaces of the kiln. This is put on before the element holders are inserted. This coating penetrates the firebrick and fuses the surface on a microscopic level which helps prevent dusting and crumbling of the fragile firebrick.
Solid ceramic peephole plugs with full 1” diameter. Three total: one per section.
