Barbara -
That all depends on how wet the clay was when you applied the slip. If it
was quite dry, it is possible that tensions developed and are still in
there. In that case, sometimes the slip will crack or peel in the firing.
You won't know until you fire it. But in my experience, it does help to dry
slip-decorated wares slowly, ESPECIALLY with thick applications of slip,
such as slip-trailing, feather-combing, or marbling.
Good luck -
