Hi Gene,



I would set it on four small pavers anyway, one at each corner, and
depending on what the Kiln's legs are on their ends ( angle Iron?
Sideways? - or on end? ) I would have a flat piece of at least 1/8th inch
thick scrap Steel as a little intermediary under each leg, to spread the
weight a little to the paver unless the leg end is wideish on it's own.

A paver being something like a flat stone or concrete stepping stone.

You may wish for the four points to be as level as possible, and to use
little wedges of some kind to fine tune the Kiln's stance.


How much the kiln weighs, and the size of those points at which it meets the
ground, is more the matter then that the ground seems otherwise firm.

Moisture comeing up from the ground also, may be a consideration, as for
whatever expanded Steel or other components are part of the bottom of the
kiln which might corrode or rust from it's influence. depending on how close
to the ground the bottom is...


Just a few fast thoughts...


Have fun...!

Would there be any disadvantage to building a gas kiln on well compacted
soil as opposed to a concrete slab???

Under the shed behind our studio the ground has been walked on, driven on
and generally compacted for about 20 years at least maybe more. I was
planning to pour a concrete slab until a friend said what we had was already
hard as concrete. Why waste the money he said. I would prefer to leave it
natural if there are no adverse effect to the kiln or a disadvantage to
building on dirt.

I plan to build the kiln with a door not a car kiln.

So what do you guys think concrete slab or plain ole dirt????
