flaw inside kiln

[cass]

I have a 24″ octagonal JenKen upright fusing kiln. The inside height is 11″. Something exploded in there, causing a depression in the center of the bottom of the kiln. The crater is 1/4″ deep and 1 1/2 ” across. Will this cause uneven heating or is it too small to worry about? Is there any way to fix it short of rebuilding bottom?

You can cover the bottom of the kiln with a ceramic fiber board. This will give you added insulation and you can use it as a kiln shelf. Ceramic fiber board kiln shelves can be placed on the kiln floor without any posts.

Thanks. Another post on another site said unless I actually fire on the bottom with no shelf there is no problem.
