Insulating Fire Brick - 2800 °F

5 items left

A High-quality lightweight Insulating Brick rated to 2800°F that can be installed in either a backing or a hot fired application.  The low iron content is also suitable for reducing and high CO environments. It can withstand the consistent operating temperature of 2650 degrees, therefore perfect for high-temperature forge welding. 

These bricks are much more porous, and not as mechanically strong as the Clipper DP bricks, though they too can be stacked dry or set using SAIRSET refractory mortar.  Though they have much less of a heat sink than denser bricks, these can still be coated with ITC 100 HT and benefit from the added efficiency of ITC 100's heat reflection properties.
