My Stove has a belly shaped stainless steel 55 gallon drum. The bottom is bent and dented. I put plaster of paris on top of it about 3/4" thick for a smooth cooking surface but it insulates so darn well I cannot get water to boil even when pushing the stove hard! Anyone know of a pourable suitable mix or whatever I could use?? Also I am getting a good ring of heat about 1.5 inches in from the ring on the barrel top. Does this mean I should adjust my gap? I get about 300F there and about 200F max in the center. The plaster of paris has some amazing insulating properties and it will hold up to really high temps! Anyhow just trying to get a smooth cooking surface that conduct enough heat. The plaster was a fail and im not looking forward to chipping it out!
