I do this all the time - no problems in over 8 years.

I've never done anything different.

Howdy all-
I suspect that success in freezing bone dry greenware may relate to ambient
humidity. If the humidity is low (as it is in alpine Colorado for example)
there should be minimal water left in "dry" unfired clay. If the humidity
in the air is higher (as it frequently is in western Pennsylvania for
example) even "dry" clay may contain enough water to cause expansion when
frozen. I remember that water will expand just before it freezes (although
I do not remember why). Since there have been disagreements about the
advisability of storying bone dry greenware before firing, different
results may actually depend on how dry, "bone dry" greenware really is.
