Dear Fellow Clay Arters,
Don't listen to me. My plates are warping. Used 6 to 8 small wads
around the foot of the plates. I got "spinners" - that is, they sank
down in the middle. It has worked for me with platters. I have another
whole kiln full of plates firing, oh well.
I wonder if 1. My plates are too delicate. 2. If I put a small wad in
the middle it would help. 3. I shoot myself.

I wood fire and this is what I do...maybe others who wad their pots.
For wide forms, ie plates, cassroles, etc. I place 3 wads on the inner foot
or close to center, then 6 on the outer foot ring or along the edge. I have
to no warping...knock on wood!

No, no--don't shoot yourself. Platters will be thicker, and less prone to
warping. Plates really need to be fired on a flat, flat surface, in my
experience. I sprinkle silica sand under them to give them a bit of moving
room. Plate setters are very nice, as they allow for more even heating
(being thinner than kiln shelves).
Give the plates a flat surface to rest on, or make them thick enough not to
warp. You probably need to do a little bit of both. It's easy to get plates
too thin, as the cut-off wire will ride up in the center, no matter how
taught you try to hold it.
