Ive seen a few one brick forges on you tube and the net but I am wanting to know if its reasonable to build a small forge out of insulated fire brick. I currently have a coffee can forge that works......but it seems that my insulation isnt as rated as high as I need it. It is boiler insulation from work and as there are no markings on the roll or anything I have no idea what it is rated at. This insulation is used inside of gas boiler fireboxes which Im sure dont get up to forging temps. Anyhow, I would like to continue forging and was thinking of building a small forge with a 2 inch by 2 and 1/2 inch the length...9 inches of the bricks. I am making small tools and hardware such as hinges in the forge so I dont need much.....but I want something that will give good heat........ Im using mapp gas now.... but I also want something that will last a while. Do you guys think that an insulated fire brick forge will last a while......Im thinking of g26 bricks 3 inches thick. Im aware the bricks become fragile over time......and I will make sure to stack and secure them in a stable manner..... I just dont want to invest in bricks that are going to crumble or disentigrate after a few firings. Im willing to spend money on the hobby.....I just want to get the most bang for my buck. Any comments or suggestions would be greatly appreciated. Also any materials sources. thank you
