Product Description

Versatile high-temp board can be cut and sanded just like wood. The board is extremely heat resistant (up to 2012° F) and has many applications.

  • Use to build a reusable mold box for casting.
  • Use as kiln shelving. Delphi Tip: support the board well with short kiln posts and use fiber paper on top of the board to prevent sticking.
  • Use to create custom molds like drop rings. Delphi Tip: cover with fiber paper before slumping.
  • Use for back up kiln insulation. The combination of rigidity and resistance to heat makes high-temp board excellent for this application.

  •   Great for drop-outs
By on
Pros : Easy to cut and shape, sands down well, holds up well after firing, and won't stick to the glass. I used this product to make a drop-out mold for use with a thick pot melt disk. It holds weight and leaves a clean surface. I was able to bevel the sides of the hole I cut in the board and sand them smooth for a nice finish. Quick and easy.
Cons : As expected, upon firing the board produces quite an odor. Ventilation is a must for safety.
Other Thoughts : This is a great product for making custom shapes without a lot of fuss.

  •   cheap crap
By on
Pros : It's cheap!
Cons : This is the cheapest grade vermiculite I've ever seen, crumbles, dusty, guaranteed to wreck whatever you're working on . I bought it to confine casting pieces and found it a total waste. No matter how careful you are it will wind up in your piece.
