I was smelting my WW's in a 10lb pot with little canisters of propane feeding my Coleman stove. I hit pay dirt today at, of all places, Harbor Freight. A cast iron 4qt Dutch oven, a cast iron 2 burner camp stove, and the regulator/feed hose to hook it up to a large tank. I did a half bucket in an hour from start to finish, it worked great.
