Dear Fred Parker,
I notice as replies are coming in you are being give tips about drying =
to restrain the motion of the rim.=20
The result of doing this will be to lock stress into the dry body. On =
firing that stress will be relieved and the rim will rise as the clay =
becomes pyro plastic.
Best regards,
Ivor.
