Preheated for 12 hours and slow fire digital. Air dried for several weeks, I had another bowl that had the same kind of defect. The thickness is consistent from bottom through the walls about the thickness of a pencil. No one who has posted seems to have had this experience. Just the expected defects from wet bottoms, too fast firing, The second bowl had almost a perfect circle blow out but half way between the bottom and rim. I guess it is a ‘who knows’ just a fluke. I was hoping for an answer that was more specific to this kind of event so it won’t be a future risk. All in all thanks to everyone for all the information.
