I've got 3 trash can raku kilns with 13" shelves.
We have a store that used to carry these shelves and they would hold up
pretty well, but they are no longer available.
Got some 13" shelves from another source, but they cracked quickly.
So.... same kilns, same firing schedule, same firebrick posts, etc
but cracking shelves.
Seems that shelf composition and manufacturer matter with such heat stress.
Was wondering if anyone has recommedations for a source of 13 - 131/2"
shelves that they use in such a setup.
I'd like some for me and some for our store so we can offer them to the
other trash can kiln people in the DC metro area. Spring is coming.
Cheers and thanks in advance!

Ed:
I don't know if this is what you're looking for, but clay-king.com sells
13X6-1/2 half shelves for about $14. Made of cordierite, which is what we
used in our raku kiln at the local community college for years.
As they're in SC and you're in VA, I don't see a conflict of interest in
asking who their supplier is.
Just a thought.
Best,
Wayne Seidl
