A fire brick is created of refractory ceramic and used to line fireplaces, furnaces, fireboxes, flues, ovens and kilns. Replace your fire bricks in your stove if the crack causes the brick to fall down or if you can see the steel body of the stove through the crack. It is advisable not to light your stove if the steel is visible. StoveTech can supply fire bricks for all models of stoves and can cut bricks to size.
