Terracolor 683 Silver Crystal Powdered Stoneware Glaze From  £11.46

I have used this glaze a fair bit and it can be a winner but only when used on the inside of pots or well way from the base on the outside as it does run - a lot! Effects of the crystallisation can be lovely, particularly inside bowls. It does tend to obscure details so keep it simple. I fire at 1220-1230C and it works equally well on whitish clays such as Scarva ES5 or buff bodies.
