Hi Pres, This pot was the worst of the blistering. Not all of them were all the way round the pot. Some had only a couple blisters but were larger. Others were similar sized blisters. I used the pink glaze once before and had no issues. It’s also on different glazes to the pink. Also have the pink on a couple other pots that didn’t blister in the same fire. The blistering on this pot is only on the top. The others have blistered on the sides closer to the bottom of the pots (same shelf). I don’t have a manual hold as I’m not usually there when the pots are being fired. It’s a manual kiln sitter so I believe I have to be there to do the hold. The coats of glaze I’ve done as per the label on the pots.

Advice needed please I unloaded the kiln and so happy with the glaze combos but I’ve noticed what I believe to be blistering on a few of them, different glazes as well. Glaze fired over 12.5 hours, I have a manual kiln with a kiln sitter and have fired quite a few times now and haven’t had this problem. Some of the glazes I’ve used before and have been fine with same application and same firing schedule. Could this be more of an element problem? Bisque fired to cone 04. Would having a bung added make things worse on a bisque? Any help would be amazing, thank you.
