I used piece of sewer pipe for the body of my forge. What kind of heat
source are you planing to use for your kiln. We use propane to fire
our forge. The sewer pipe has a thickness of aprox 14 gauge. I don't know
what smoke will do it. It might do nothing to it. We purchased our ko-wool
from a place that sells and builds wood stoves.
Send me some more info about your kiln and I will ring up the place we
purschased it and ask.
About fire bricks. We use fire brick for the bottom and ends of the forge.
We are noticing that after awhile the heating and cooling of the bricks
is starting to make them crack. My best friend builds industrial size
kilns, induction furnaces and they pour the linings for them. I will
give him a call tonight and pick his brain for you.
