Pizza stone versus pizza steel We looked at stones made from steel, ceramic or cordierite stone, and cast iron, all of which have different thermal properties, and thus, different uses.

Examples include alumina, aluminum nitride, barium neodymium titanate, barium strontium titanates, barium tantalite, Beryllia, boron nitride, cubic boron nitride, glass ceramic, and cordierite.

Cordierite has a low coefficient of thermal expansion ... High purity, amorphous, fused silica is a high-performance ceramic with very low expansion, remarkable thermal shock resistance, low thermal ...
