Scarva GZ2191 Zinc-Free Multi-Purpose Stoneware Transparent From £9.40

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.
