I stacked them inside each other. Some of the other clays seem to have over fired slightly and these ones turned blue. Slight weird reduction maybe?? The one on the right is how it should look. I think they were too tightly packed and have had their own firing party.
Interesting anyway and a lesson for me in how to stack a bisque fire
