Dear Katie Ellis,
If your work is thrown then you may need to adopt the system used by
the Zinc Crystal people.
They turn a catch plate that is in contact with a foot ring all the
way round. Fire the two part together during bisque then use a slurry
of Kaolin/Aluminium hydrate to separate each pot from its support for
the glaze firing. This should resist the effects of Sodium Carbonate
so that the parts easily separate after firing.
Best regards,
Ivor Lewis.
