Terracolor 5133 Rockpool Gloss Powder From  £18.67

Settles very quickly, however a small edition of Epsom Salts cured that.Runs during firing but beautiful effects can be achieved by applying over a dark glaze (second dip), looks particularly good over dark blue.
A 20 min. hold at 1040c is optimum.

This gave great effects, with a good range of colour and nice even coverage.

This glaze was just like my green glaze made using copper carbonate and the transparent glaze. I was expecting the glaze to have something extra, but I maybe made it up too thinly. Will add more to see if I get a better result
