George that is a refired bowl. Originally all white. Second firing put heavy coat of noxema blue. When it dried it cracked and didn't adhere to the originally fired glaze. Probably could get the same effect with putting wax resist over bottom glaze and new glaze over the wax resist. When it dries it should crack???but don't know haven't tried that. Got a wonderful effect that you probably cant see from the picture. Looks like lighting in a bowl.

This looks like the blue glaze developed drying, shrinkage cracks, and then the white healed all. That's happened several times for my glaze combos. More typically, some cracks/crawls would heal and others, not so much. A little too uncertain to really be an intentional technique. It looks like maybe some crystallization as well?
