building the EAC wood kiln

The kiln is of the Olson fast-fire design. We left out the little hole for poking out a brick designed to reduce the size of the flue to the chimney. We miscalculated the number of bricks and ended up with a chimney that was way too short. the first time we tried to fire it we made it to cone 04 after 20 hours or so and gave up. We then added a three foot stove pipe to the top and got to cone 10 (barely) in about 20 hours. The kiln stayed like that for five or six firings, struggling to get to temp and then eventually another 3 foot section of stove pipe was added. Now we can get cone eleven flat on the bottom (if we want to) in about 18 hours.
