I liked the idea of a rocket kiln -- less fuel, more heat, less time. It was an interesting experiment but not a raving success. I made a few mistakes, learning as I went and sometimes, sadly, after the fact. The temp inside my barrel kiln reached 1480F at its peak -- short of my goal of a sustained 1900F.

I got the idea from a video I watched about building rocket stoves. I later learned that concrete -- even vermiculite or pearlite concrete -- is not ideal for achieving the kind of temps that firing ceramics requires. However, I'm sticking with it for now, even in my rebuild. There is curr
