I did not tune in on this earlier, so this may have been said: If you are in
a cold climate where it freezes seriously in winter, you may have to
consider frost heaving. There is much discussion about it--some say did a
deep hole, fill, etc. to make a good foundation that goes below frost line.
Others say nonsense, the kiln will float and will move no more than it does
at white heat.
I know zip, nada, nothing about it...just bring it up as something to think
about....

Hi Lili of good courage,
I am in 'da U.P. of Michigan with 4'-6' frost and in my studies followed some of Michael Cardew and Bernard Leach's recommendations to use a bolder, cobble, and gravel foundation about 3.5' deep under the chamber and 2.5' around the perimeter as a working area. The prime reasoning is to prevent kiln damp from entering up into the kiln through capillary action from soil to concrete. Mel and his slab crew have come up with an ingenious moisture barrier over cement but it lacks the aesthetic of the natural stones and softness to foot of gravel which will prevent fatigue during the week long firing with wood. I already spend 9 hours 3 days a week on concrete covered with tile at Wally World and that's enough for me and my potters toe. Working around this kiln is like floating on cotton candy and it's almost ready to fire to bisque... so stay in there eh!
