terra sig problems

Dear Friends,
I read Antoinette's problem and thought nothing about it until it struck =
me that it would seem that there is either no bond, or a very weak bond =
between the Terra Sig she is using and the clay on which it is placed.
Now this seems a strange turn of affairs. Has anyone else had this sort =
of trouble before? Is it a technical problem which might be resolved by =
increasing the firing temperature by a reasonable margin? High enough to =
ensure fusion bonding between the Terra Sig and the base clay but not =
enough to cause massive melting of the terra sig which would destroy the =
surface texture that gives the subtle sheen.
Any other ideas out there?
Best regards,
Ivor Lewis.
