I have two gassers one is the big and thick one and the other is a coffee can Both are lined with kaowool, satinite and itc 100. I use the coffee can more than the big one. Woody is right The steel casing is only to hold the insulaton . Click on the link provided http://refractory.elliscustomknifeworks.com/ you see everything from steel, bricks, COFFEE CANS, and some funky looking sheet material. Oh and also just because the shell is thicker it still gets HOT :shock:
Just my .0000002 cents
