Hi Community! I took some dishes out of the kiln around 230F and there were some small white looking flakes on some pieces that I tried wiping away with my mitts. I think it was from the kiln shelves? Two of my bowls look like some flakes got stuck in the glaze? Can I grind these parts out without damaging the food safety of the dish? Any suggestions or thoughts on these white flakes? dk
