No clay in it or soda ash. Uses calcined Alumnina Oxide.

Looks like a nice, workable glaze, Lee. What else is in it?

Hollis, it is John Britt's Mino Shino. Has no clay, uses calcined Alumina, Alumina Oxide instead. I used low melt spodumene.

Interesting I have been recently doing some shino tests with alumina as well as zircon. I also have been adding a bit of lithium carb.

dernster, In Mashiko I was doing a 60% Neph Sye 40% Korean kaolin glaze. I could sub alumina hydrate for the Kaolin and still had a workable glaze. I found in my wood kiln, that would reoxidize on every stoke, that you needed a higher alumina level to get red color. My American Shinos would not work, they were always grey.

Lee, to what temperature do you fire alumina oxide in order to get it calcined? Can I put it inside a greenware and bisque it to cone 06 or 07?

Hello Hisakyuu! I think it is fired to 3000*F That is why it is expensive. I buy mine at Continental Clay. But you could try bisque temp calcining. Someone recently told me they tried this with fine alumnina hydrate and they had some success. Thanks for your note. Good luck! Please share any experiments you do!
