Rich, after a while it will die. Tho, 3/4 is pretty thick, and will last a while. Have you insulated the burn tunel and heat riser? The bottom of the feed tube?
It will start by spalling, then you'll find pieces of metal when you clean it. If well insulated, it might melt too. If not insulated, it's not a rocket yet
Thoses metal stoves can be amazing, because the red (orange may be even yellow) hot metal is like a catalyser on the gases. It's a shame it doesn't last. Tho, i'm at the stage where i can make the end of the batch box and beggining of the heat riser of a batch rocket, made out of fireclay!
It doesn't show in it's full glory, because of the infrared filter. But it was bright orange.
