After a week or so of problems with some cracks and dunting I was really happy to unload this great big platter. It's perfect all 18" x 9 1/2". Ahhh. Non- Potters just can't even imagine the number of rejects we get. There are just SO many variables - Drying, Bisque, and Glaze issues, the last two weeks I was beginning to really wonder if the kiln gods were making me pay with some sacrificial pots. Why Me? Hopefully that's in the past.
