This glaze came out looking very much like a popular cone 6 glaze called Floating Blue. The trouble with the original Floating Blue glaze is that it contained Gerstley Borate as an ingredient and therefore it was rather finicky and unreliable as a glaze.
My glaze does not contain Gerstley Borate and so should behave a little better in the bucket and on the pots. I fired this over Rovin's RO-20 clay body. It is a cone 6 clay body that is high in iron.
