High-density high heat tolerant Firebricks rated to 3150°F. These bricks weigh 7 lbs+ and are HARD.
These bricks are structurally strong and will not melt even at forge metal welding temperatures. For lighter weight, high insulating and easy to cut INSULATING Fire Bricks (IFBs) look at: insulating bricks.
NOTE: not all firebricks that look the same are the same. In the image below compare two different, but similar-looking bricks coated and heated for 6 hours with a few ounces of welding flux. Our super-duty bricks were fine, the generic bricks, rated to the same heat, were completely deformed and cracked from the Flux. Don't be fooled by appearances and superficial claims. Not all firebricks are the same. We use thin Super firebricks as sacrificial bricks so chemicals (fluxes) don't destroy the main structure.

Tip:
Applying ITC 100 HT is a great way to reflect heat away from the brick, into the forge. It prevents the brick from acting as a 'heat sink' as the forge heats up.
Introducing our Brick Cutting Room with the Overhead Radial Diamond Wet Saw. We recovered, restored, fortified, rebuilt, and enlarged the saw that was custom-built for the original construction of West Edmonton Mall. Restored, under new power, and lifted with a larger blade to accommodate larger slices, it is also equipped with our proprietary brick cutting jig that repetitively slices to fractions of an inch.
Note: although classic clay bricks are fired in a kiln and can handle considerable temperatures when the heat is constant, they can't handle thermal cycling. The differential expansion stresses of heating and cooling cause standard bricks to progressively microfracture to the point of failure. One of the principal characteristics of refractory bricks is their ability to withstand differentials in thermal expansion.
