Dear Clayart
I am making a big batch of plates. How can I make sure that the plates are
standing on its rim properly without wobbling? Is their a way to fix it,
either when they are leatherhard or dry?
Thank you

Karin, I'm sure you'll get better answers than this, but when something
wobbles - at the dry stage, I place it on a flat canvas covered board and
move it around so that the bottom is being sanded flat. I use a little
downward pressure, but you do have to be careful as plates do not take too
much of this.
The other thing I've noticed about plates is that bottoms often flatten out
in the glaze firing. If they were thrown ok and the problem was warpage
during drying this sometimes self-corrects - at least with the clays I've
used.
Actually you said rim, not foot. Maybe I musunderstood your question?

Karen-This seems to be more of a problem with dinner plate and larger
diameters. I set the plates on their rims (upside down)after trimming
and if their bases start to swell up I press them back down. The amount
that they distort is a function of the clay composition, speed of
drying and their thrown shape.

Lou Davis sells mesh screens specifically for sanding bottoms flat.
Just attach to flat board, place dry greenware on screen and move
around. The screen can be brushed out and lasts for a long time. We
use it extensively on plates, especially oval shapes which tend to
have a little bit more warping. Takes out any bit of wobbling before
it gets aggravated in a firing.

Berry,
Are these screens better than dry wall screen? Will they last longer?
Thanks. Who is Lou Davis?
