I got a load out of the kiln today, fired to cone 6, and I have a few pieces glazed in Leguna's Robins egg that are pinging. I took them out at around 100f, and there is no crazing that I can see. It is meant for this firing temp so I am just unsure of whats happening. Has anyone else had issues with this glaze? Can I continue firing like normal or do I need to change something, maybe it would work better in cone 5?
