Scarva GZ2191 Zinc-Free Multi-Purpose Stoneware Transparent From £10.37

I purchased this zinc free SW glaze to replace the Sahara version that always seems to be sold out. I am pleased I tried this version because when I added a red ceramic stain the resulting red glaze over porcelain at 1250C with a 20 minute soak was remarkably good. Highly recommended if you want true colours the using stains, underglazes or with stained bodies, black for example.

Fired to 1220 c. Electric kiln. Brushes on well. No crazing
