Overview of Shino Glazes ( Video #31 in the FREE online Glaze Course)

Overview of Shino Glazes. In this video I try to explain a bit about shino glazes and then show a group of recipes in 5 firing cycles on three clay bodies.

In Japan, original shino is just high alumina feldspar. Weathered is the best. Wirt used (from Louise Cort's book) the Freer analysis of Tajimi shinos to do her tests in Minnesota. She didn't have enough soda feldspar so used soda ash to compensate. The discovery was that the addition of soda ash lowered the firing temperature of the shino allowing it to mature in hours instead of days. That led to the adoption of shinos world wide. Alumina Oxide also lowers the firing temp. Original Shino was only made for 60 year, 400 years ago.

A true master

Amazingly timed video. I was curious about subbing the ball clay with wild clay and what you might watch out for. I have a wild clay that behaves similarly to Albany slip

[@johnbrittpottery]

Yes. I used "Wild Shale" ball milled.

[@deepashtray5605]

Excellent stuff. Have you ever tried to make a Sung Dynasty iron blue?

[@johnbrittpottery]

Yes, 25 years ago...settled on Pinnell celadon with 3 Barnard, 2 barium card and 1 tin.

[@danifogarty2003]

can any of these be used in cone 6 oxidation?

[@johnbrittpottery]

Not really. Best at cone 10 reduction. Shinos need reduction but , I have recipes and cycles in my midrange book for cone 6 reduction shinos.

Is Shino glaze safe for food?
