Cerablock 1100 - 50mm
Suitable as an underlayer for firing, especially in larger, flatbed kilns where a normal kiln shelf is too small. Can also be used for making slumping moulds. Easily cut to size with a sharp craft knife, or carved into for relief work. Has two sides: a semi-smooth side and a side that imparts a textural &39;granite&39; finish to the underside of the glass.
The board is permanent when treated with Colloidal Silica Hardener, otherwise it will soften and deteriorate over time. Kiln wash required e.g: Bullseye Shelf Primer.
Please Note: 100cm x 60cm Cerablock available for COLLECTION ONLY!
