That is super cool - thanks, Jason!
So, you can get to 1000 degrees Celsius easily with a couple of simple L-shaped 6" rocket stoves and fire a 41" square (the base) kiln with not a lot of
wood. So cool.
It warms my heart to see all those rocket stove cores in the truck, ready to go out into the world and save fuel (not to mention people's lungs)!
