I have a new kiln (Coneart oval) which developed a crack
(NOT hairline) across the whole bottom in the first firing.
I know that hairline cracks in the lid are to be expected, but I
never experienced a big crack like this with my other kilns.
I was told that this is "O.K." and wonder if anybody else has had
this experience in the first firings? I am concerned because
there was other shipping damage, but I thought the bottom was
not affected.

Dear Susan:
I have seen this occasionally. If you have a good support under the bottom
this should probably not be a problem. We put a sheet of aluminized steel
under our larger rectangular kilns. I assume Coneart has a good means for
tightening up the casing. Because all our bottoms are separate you can
tighten up the band around just the bottom or top which keeps the bricks
all together. I'm not sure what Coneart does. If it is one piece case
construction this would be difficult but you should talk to the manufacture
and see what they say about this.

Hi Susan,
As you pointed out, hairline cracks in large oval brick slabs is quite
common. As long as the crack is not opening up, it shouldn`t affect the
firing. If it is really bothering you or if it is opening up, tell Coneart
about your concerns again. They are usually very helpful. I would think
they would want to have a look at it, maybe just the band is needs
tightening up.

Susan.. i get a high temp cement for fire bricks at Acme Brick..i think most
brick yards would have something similar.. It fires very high.. above cone
10.. and is simple to use.. Just fill the cracks with the mortar.. let dry (it
air drys) and fire as usual..if the crack are very wide.. use some ground up
fire birck and mix with a little of the cement.. Hope this helps you get it
fixed..
