An alternative to firebrick would be the old red clay solid bricks. In the oven, these alternative red clay bricks heat, cook, bake, roast, re-burn, absorb conductive stores, retain heat from wood fires, and perform just like a proper firebrick.
Why is firebrick so expensive?
High-Duty Firebricks These bricks have a very high alumina content, get very hot (>1500F), and are designed for continuous high heat applications such as furnaces. They are expensive and also get too hot for oven use, such as baking and roasting bread.
What happens if fire bricks get wet?
Fire bricks are porous, absorb moisture, freeze, expand and crack (spall).
Do fire bricks expand when heated?
Be sure to set spacing guides before placing the bricks. They should be placed so that the ½-inch expansion gap comes off the back and side walls. This expansion gap allows the firebrick room to expand and contract as it heats and cools.
Does firebrick have asbestos?
Fireblicks and their mortar contained up to 80% asbestos. Because the asbestos additives did not burn off or distort no matter how hot they got, the fireboxes, flues, and chimneys withstood prolonged periods of direct flame contact.
