I'm using 2" 2600deg fiber board with the coating of ITC added. Couldn't be happier! My latest forge is designed exclusively for welding. Forced air with ajustable airgate valves and individual needle valves on each of the two burners. Having control over the important elements is key. Have more than enough air available then chock it back to ideal. Same on the propane, I have a regualtor at the tank then a flex hose to the cutoff ball valve, then the line splits...goes to needle valves and from there the gas pipe is weled in place in the direction of the air flow. The whole thing looks like something Doc Brown would have made in his laboratory. Not pretty but it gets really hot in a hurry. My internal dimensions are 4" wide 5 "tall and 12" deep.
