I have a theory, it is only that--that some clays resist pressure less well
than others. I have had experience with bodies that allowed stacking bowls
inside each other, helter skelter, during bisque, and others that deformed.
Then: some book, no idea which, says/said that if you stack bowls inside
each other the foot rims must coincide. That makes a kind of sense. If
the foot rim of the inner bowl is actually resting on the trimmed bottom of
the outer bowl, rather than smack above ITS footrim it will deform the
outer bowl, and then itself. It all depends on the weight of the inner bowl
and the thickness of the bottom. As I do not do foot rims I. know little
about this problem, if it exits.

I was taught to stack bowls by filling with a course sand as a
tends to overcome any tendency to warp in the bisque ,especially
The sand will need to be calcined first and then keepted in a dry
This is how my first teacher " Richard Brooks " was taught
by " David Leach ".
