I have broken so many fire bricks that I have started to research variations. I use them to block off sections of my big forge and for sacrificial floor liners when forge welding but they are so thick/heavy and awkward to move around when hot that I have broken enough to build a small house. My new plan is to create some forge "doors" and furniture using one inch inswool and a castable refractory. Simple plan; cut wool to size and coat both sides with layers of refractory to make it rigid. It will be much lighter and easier to move around when hot. I can buy blanket inswool much cheaper than board inswool so do you guys think the blanket will harden enough to handle light moving around or should I buy the board. My thought is that the board is quite brittle and prone to breaking in the first place. Hopefully the blanket would not break if dropped and then I could just repair the cracked refractory if needed. Thoughts or experiences please.
