Masonry oven A masonry oven, colloquially known as a brick oven or stone oven, is an oven consisting of a baking chamber made of
Ceramic foam area. It has been used as stiff lightweight structural material, specifically for support of reflecting telescope mirrors. Ceramic foams are hardened ceramics with pockets of air or another gas trapped in pores throughout the body of the material. These materials can be fabricated as high as 94 to 96% air by volume with temperature resistances as high as 1700 °C. Because many ceramics are already oxides or other inert compounds, there is little danger of oxidation or reduction of the material. Previously, pores had been avoided in ceramic components due to their brittle properties. However, in practice ceramic foams have
