Collection: Firebricks

Stores heat and protects against fire. A fire brick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is designed mainly to withstand high heat, but should also usually have a low thermal conductivity to save energy. Usually dense refractory bricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from wood, fluxing from ash or slag, and high temperatures. Dense refractory bricks have a high thermal mass which is sometimes a useful property in that they will retain heat e.g. in a pizza oven after the fire has been taken out. It is strongly recommended to use the right quality for efficiency and durability.
