Repairing the lids are difficult because of expansion and contraction during firing. I bought a used lid from our local ceramic supplier last year for around 50 dollars much less than a new one. They rewire and rebuild kilns at the store, perhaps you can find someone who rebuilds. Denice

They make a special lid cement that will not fall-I'll post the name/brand of it in a day or two as I need to head by the ceramic supply shop where they carry it.

The old name was Lees Patch now its called Axner Patch-You can order it online from Axner.com. I think they bought out Lees's??
Axner is Laguna Clay Company.They bought out Axner.
Its made for hot surfaces and is not supposed to fall off-Its made for this Job I'm told.
Remember this job needs to be prepped- remove loose material then vacuum lid 1st
Then follow instructions with this stuff.

Patching or reattaching old bricks is sketchy at best, regardless of the claims made by Axner. A thin coat of cement to keep broken bricks from dropping little bits onto your pots will work, but mortaring a chunk into place is likely to fail. If chunks are less than half way through the lid, I would just leave them out. If the lid is cracked all the way through, you'll need to replace the whole slab.

Im looking for the best bonding and filler to use to reattach cracked pieces of a kiln top. Please use laymens terms since I am just starting out. I bought an old kiln and it needs e few repairs and I'm on a tight budget so I am learning DIY kiln repair. My main concern is that I was told some cements will flake off during firing and damage the finish.
Where is the damage to the lid? Around the edges, or toward the center of the lid? Is the damage on the inner or outer lid surface?
