This idea intrigues me, if for no other reason than to question the need to
refire to the original cone value. For most glazes, I think going up to =
eight hundred Celsius should do the trick.

Correct me if I=92m wrong in thinking this way, but I understood that =
being glass, always had lower melting or softening temperatures than any of =
original compounds used in recipes and that this was especially true of =
which contained Sodium, Potassium or Boron through incorporating one of the
feldspars or Gersley Borate

So, if it is only a glaze defect which has to be corrected and is not a =
of an immature body, why take the work back up to cone 8 plus?

It seems to me that this is a matter of convenience because we have space in=
next firing and the decision to fire so high is not based on technical
