Hanger Bricks

substance used to line fireplaces, fireboxes, kilns and furnaces. Although a refractory brick is typically made with a low thermal conductivity for better energy efficiency, it is designed primarily to withstand high temperatures. In applications with intense mechanical, chemical, or thermal stresses, such as the interior of a wood-fired kiln or furnace, where materials are vulnerable to abrasion from wood, fluxing from ash or slag, and high temperatures, dense firebricks are typically utilised. Other, less severe circumstances, as in an electric or gas-fired kiln, call for more porous bricks.
