The Kiln brix we produce are made of vermiculite- a natural inorganic mineral belonging to the mica-minerals group. Raw vermiculite is exfoliated by a high temperature heat treatment in the production process and expands to a lightweight aggregate which is blended with inorganic binders and pressed to form boards.
Vermiculite kiln brix is extremely heat resistant and has many applications.
It can be used to build a reusable mold box for casting, as kiln shelving (just make certain that you support the board well with short kiln posts and use fiber paper on top of the board to prevent sticking).
You can also use this board for drop rings and other similar molds (again, cover with fiber paper before slumping) .
The combination of rigidity and resistance to heat(up to 2012F/1100C) also makes vermiculite board an excellent back up insulation for kilns.
Keep in mind that this board is more rigid than most fiber boards or other refractory materials.
