Apologies for not thanking you for your input. Cyberspace ate my password and I've been trying to get access back in between workshops and preparing for a sale. All seems well now thanks to Jennifer.
I assumed that the bowls had a glaze on them because the inside surface was so juicy and there were drips on the edges of the bowls, facing up of course.
Would a shino glaze release the wadding more easily than others?
Thanks again for your comments.
