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 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.
Sold per brick.
