I have a friend with a problem. Glaze popping off flat ceramic pieces in the
same place on different pieces, but not all pieces. It has been underglazed
with a green color, fired, and then glazed with a clear glaze. There is a
pop off in the same place on several pieces. However, other places on the
piece are also painted green and do ok. I work in high fire. Can anyone
help? If so email on this list and I will relay or email her directly: Thanks, Tonya
