Bricks do not contain highly toxic compounds. Tests to evaluate the encapsulation of potentially damaging chemicals in waste materials have shown that no toxic compounds are leached from bricks. A brick is a 100 percent inorganic, inert material.

Can you cook directly on fire bricks?

Fire bricks have been used to build the cooking chambers of wood-fired ovens for centuries. Fire bricks provide the consistent high heat required to blister pizza dough perfectly, and their non-porous surfaces are perfectly safe to cook on.

Can you use regular bricks for a pizza oven?

So can you use old brick into a pizza oven? If the bricks are made of clay and are kiln fired (firebrick or red clay brick) they can be used for a pizza oven, but if they are concrete bricks you should stay away. Clay bricks can withstand the heat from a pizza oven, and concrete bricks can’t.
