A little while ago I washed some bisque ware and then didn’t get around to glazing it straight away. A few days later I noticed these yellow marks appearing and wasn’t sure whether I’d be wasting my time glazing it.
So I asked for help, and lots of potters shared their experiences and reassured me it was unlikely to be a problem. Thankfully they were right 😊
The yellow marks completely disappeared after the glaze firing.
I did a bit of digging and chatted to more potters to understand why this happened. From what I could gather, this can happen when minerals and impurities in the clay are drawn to the surface as the water dries.
Thank you to everyone who took the time to reply to my stories and share their tips. It definitely stopped me worrying about glazing these pots 💛
