Can bricks be toxic?

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.

What are fire bricks made of?

Principal raw materials for firebrick include fireclays, mainly hydrated aluminum silicates; minerals of high aluminum oxide content, such as bauxite, diaspore, and kyanite; sources of silica, including sand and quartzite; magnesia minerals, magnesite, dolomite, forsterite, and olivine; chromite, a solid solution of ...

What's the difference between fire brick and regular brick?

Thermal conductivity of regular bricks is much higher than with fire bricks. Firebricks can withstand high temperature because the ceramic, ferric oxide and other chemical additives absorb, and do not transfer, high temperatures. The low thermal conductivity offers greater energy efficiency and insulating value.
