Need advice on material for an indoor firepit?
I'm looking at building an indoor firepit that uses ethanol fuel. I have it all planned out and everything but need advice on material. It will basically be a hollow sphere that is open along the front and sides and will have the ethanol fuel can placed into the bottom. This will all be supported by wooden legs. I'm thinking of using a clay straw and sand mixture (COB) because it's very strong and fireproof but I'm not sure if it's the best option. Does anyone have any ideas?
