I want to fire a 26 x 22 inch porcelain tile vertically
since it won't fit in my kiln horizontally.

Should I try to keep it as vertical as possible ...
will a bit of a lean hurt? It is kind of wavy anyhow
so a bit of movement would not be tragic.

I was going to balance it against a half shelf
part way up the kiln ... does this make sense?

I usually once fire smaller ones to Cone 8 since I do not
glaze them .... would there be any benefit in bisque
firing the larger ones first?

The biggest challenge will be loading it without
breaking it .... nerves of steel ....

Anyhow ... the great discovery at NCECA ... for porcelain
firings .... is the Kaowool Ceramic Paper ... lay this stuff on your
shelves and it moves with the porcelain so no more sticking
to the shelves at high temperatures.

Woohoo ... it works !!

song that was out a couple years ago ... it was about taking every single
precaution a human could possibly take ... but you're still gonna die !!
Was it Randy Newman?

Chris:
Porcelain loves to stick to cordierite shelves.

That ceramic paper sounds like just the thing! Larkin Furnace?

Chris- if you bisque this first, it might shrink enough to allow you to
lay it flat for your high fire. If this turns out to be the case that
might work better for when your porcelain gets closer to those wiggly
saggy upper temperatures. Bisquing the tile on edge should work fine
(of course this isn't *guarenteed*!).

congratulations on not letting your kiln size limit the size of your
creation!
