Put a 1/4 flat plate of steel under bricks and this all goes away.

I put a 1/2" layer of concrete "Hardy Backer" board under it. Hope for same effect.
In Topic: Candling?

Posted 23 Oct 2012

Candling is slow heating kept below the boiling point of water ... About 200F or the very lowest setting with the lid propped open to let moisture escape.

Does candling work? I'm a little scared, as my last firing had one item blow up and ruin everything else in the kiln. Think that one item was wetter than the rest.

Thanks. I'm starting to think I should just go back to the Skutt stand. With those cracks in the bottom, I wonder if I shouldn't build a firebrick on concrete board 'table' to put on the Skutt stand and the kiln on top of that. I have little space in my shop, so the wheeled dolly (which I had sitting around) seemed perfect. But burning down my house is the risk for the benefit of a little comfort.

No. Not an issue or problem. Suggest, as a general practice, putting a shelf supported on 1/2 inch posts to serve as bottom. That gives you some space underneath for air/heat circulation. Plus, avoids wear on the kiln floor.

Good! Also, I've taken this kiln off its rusty old factory issue stand and put it on a heavy duty steel roller dolly. Is this a bad idea?

To what cone or temperature did you fire this LG-10 glazed ware?

Fired to cone 05. Using very old Skutt with bar type cone in Kiln sitter. Some things on the most problematic shelf came out perfect, but these had much more vertical surface. The orange peeling ones were 95% flat, and I think I put so much glaze on it pooled in the middle and couldn't finish properly. This was my 1st firing/test of this system, will no much more soon. Will use only 2 coats with same application method.
