P>S> didn't mean to imply that there should never be any differential
in tension/compression,
(for example, compressing a rim is useful in keeping a thrown rim in
round,etc)
clay bodies vary , conditions vary, forms vary
Many, many factors affect how much difference is too much...for any
given cset of circumstances.
and whether that may result in cracking or warping...
