Kurt, you lucked out there. I've seen them warp even after they were very
hard leather hard, once the weight was removed. I think it has to do with
the clay body you use. I like to let mine get bone dry under weight.

Don't know if I read about the use of sheet rock for drying tiles on
Clayart or where I heard it.
Anyway, I want to recommend it highly for keeping tiles flat while
drying. I rolled out slabs on a slab roller and used Mel's suggestion to
cut the clay with a pizza cutter. Next I dried the tiles between
sheetrock. I stacked sheetrock, then tile, sheetrock tile, sheetrock tile,
etc. five tiles high and the put a hard brick on the sheetrock over the
last tile. I let the tiles sit that way for 15 days then unstacked them to
dry further in the open. When I unstacked them they were still a bit damp
but were very hard leather hard. When they dried to bone dry they were
nice and flat.
I am so happy with nice flat tiles and whoever posted that on Clayart - if
anyone did - thanks a hellofalot!

Dear Kurt, I'm picturing all that weight on the tiles; does that keep them
from shrinking the normal amount- how can they move? In other words, did
they get smaller, or just thinner?
Good firings,
Ann Brink in Lompoc CA

INteresting. I think ambient humidity might be a factor too. I usually just
use old catalogs & magazines on small pieces to weight them down & I use
sheetrock on larger flat pieces. I even use the catalogs on tiles, but I live on
the front range in Colorado where 40% is a really high humidity day & it
virtually never rains :-)

Kurt, when I do tiles, I roll them with a slab roller, cut them out with
a straight edge and exacto knife, place them on plaster board and cover
with a single layer of plaster board. This sort of makes a sandwich.
After several hours, I turn the sandwich over an allow to sit over
night. I continue this"turning over" process until dry.
So far I have had no warped pieces.

Yep. Sheetrock is just a brand name. I keep things
from sticking to it by laying pieces of thin,
loosely woven synthetic fabric over it, under the
clay. It lets me move the clay around on top of the
drywall, doesn't inhibit shrinkage or hold moisture,
and doesn't rot.
If tiles warp on drywall, the top sheet of drywall
may not have been adequately weighted. Also, the
drywall gets damp from the clay, and the top layer
of any stack will tend to both dry out quicker and
have less weight on it, too. So, I like to rotate the
top to the bottom if it's convenient. If it's only
one layer, I flip it over to let the bottom sheet of
drywall dry out a little too. Or put a sheet of
plastic on top to make the top dry slower, AND add
some weight. For total evenness, I'd wrap the edges
of the stack, too, so the tiles closest to the air
don't get a head start. It takes a little longer
to dry the tiles, but works well.

Yes, but don't use the sheetrock as a workboard (to impress or inlay the
clay) and then leave the tile on the board to dry or you may come back to
find the
clay very stuck to the sheetrock. Ask me how I know. ;-)
This, assuming I actually know what sheetrock is...also called drywall?

in Elkton, MD- who dried tiles on squares of drywall and they still warped.
-Used a tile cutter to make them and wondered if that contributed somehow.
