Heavy-duty firebrick offers stability and high density with good chemical and atmosphere resistance.
These are similar to the Clipper DP bricks split in half and are popular as a replaceable forge floor, or as sliding doors at the front or rear forge opening.
Applying ITC 100 HT is a great way to reflect heat back from the brick to the forge, rather than having to brick act as a heat sink as the forge heats. When using flux falling onto the floor of the forge, the ITC 100 HT can itself be coated with ITC 296-A for increased durability, flux resistance, and a very tight ceramic finish.
