Will a thick wall of high temp refractory cement (5000f) work on its own to line a propane forge? What is the benefit to lining with kaowool?
I'm planning my first shop made propane forge, I can't find kaowool locally, but can get other ceramic high temp insulation. However I have come across reasonably priced high temp refractory cement (5000f), I'm thinking this will work like fire brick. The benefit being that I should be able to patch it with left over cement later when the flux has damaged the inner surface. Any thoughts, advice, warnings?
