Refractory Fire BricksKiln BricksCharacteristics
Dense refractory bricks have a high thermal mass which is sometimes a useful property in that they will retain heat eg in a pizza oven after the fire has been taken out. Kiln bricks are made by firing a clay based composition in the kiln until it is partly vitrified and for special purposes may also be glazed.
