Impurities in refractory clay, such as alkali, sand, iron oxide, calcium silicate and magnesium silicate, can adversely affect their performance. At high temperatures, refractory clay loses its water of hydration and is mainly composed of alumina and silica. The method of making refractory bricks is the same as that of silica bricks.

23/09/2021Fireclay is typically divided into grades depending on the type of fire resistance needed. The inside of a wood-fired kiln or furnace needs a firebrick made of high-density clay because these are subject to extremely high temperatures. They typically use bricks with more alumina content, as much as 40 to 44 percent, and are considered high-fired

REMET UK Fused Silica is made from pure, natural white silica rich sand at 1980oC. At this temperature, the crystalline quartz melts and becomes non-crystalline. The resulting refractory is a pure material that is readily available, which provides a long life slurry practical for both ferrous and non-ferrous metal casting.

Insulation value does. Use kaowool or at least something like perlite, shred styrofoam or straw. Your forge might still work, but it will waste lots of fuel. 2500F rated refractory is insufficient. Propane has an adiabatic flame temp of 3000F - real temp will be lower but you'll want to use refrac rated at least 3000F.

Sand Core Making. Cores are produced by blowing, ramming or in heated processes, investing sand into a core box. The finished cores, which can be solid or hollow, are inserted into the mold to provide the internal cavities of the casting before the mold halves are joined. Sand cores are also widely used in die-casting, where permanent metal
