I glazed a couple of volcanic/crater glaze tapered bowls recently. They almost "half" work- but I'm still not convinced I've got it right- although it's promising. I layered combinations of glaze but I'm having a slight problem with the thick layers of silicon carbide glaze crawling. Sticky fingers maybe? Lots more to come over the next few months, probably with the next recipe- Pinnel Strontium Crater - with a variety of glaze stain additions . It's a pretty reliable recipe so fingers crossed.
