Hi all,
My electrician was here and he said he thinks the material I asked about was
just layers of rust from the sheet medal. He said he thinks I could fire the
kiln without the sheet medal bottom. He thinks all it does is keep the heat
in some and protect the fire brick. He told me where I could get another one
made. Is it safe to fire without the sheet medal bottom if I raise the kiln
up off the floor with brick?? It's a concrete floor and cinder block walls in
the basement.
What do you all think? I'm new at all this.
Thanks for your help in advance. Judy

>Judy, The sheet metal aqt the bottom of the kiln has only one purpose and
that is to prevent the bottom bricks from falling out on the floor.
Pesumably the kiln rests on a metal stool. If not,it certainly should. An
air space at least 10" between the kiln bottom and the floor,is about the
best insulation you can get since it isolates the kiln from the floor and
also provides circulating ventilation. The metal botto should be replaced
or at least covered wwith another sheet. Resting the bottom of the kiln on
the floor traps moisture between floor and kiln bottom and,even with S/S
encourages rust. Always have plenty of air-space. Don & Isao
