I’m very happy with the test results. Tweaking these recipes in my cone 8 kiln so that I can get as close to possible before taking up precious room in the big gas fired cone 10 reduction kiln. All of these recipes are based on the Leach 40 – 30 – 20 – 10 recipe method which so far seems very stable. Getting the specific gravity dialed in is important.
So I’ve got all the chemicals I need to make a vast amount of glazes in my simple palate and color range. Testing to cone 8 in my electric kiln so I can tweak it as close as I can before putting it into the big gas fired kiln at cone 10.
- Zircopax white over temmoku
- White over Celadon
- Temmoku over Celedon with a dip into the red iron oxide (FE2O3) as a differentiator test
- Clear glaze by itself
- Zircopax white by itself.
Im really excited about these simple glaze combinations. Along with red wild clay slip from the lake and black slip that goes to cone 10 I have a wide range of decorating possibilities to play with.

John Britt’s Complete guide to High Fire Glazes has enough information to keep me busy for many years! Big thanks to Jay Benzel of Benzel Pottery for loaning it out to me.
Another thing I was working on was pulling technique and made a nice delicate serving spoon. Beautiful right?!
Years and years ago I got up the courage to develop my own black and white film after reading an article that gave me the very basics in a way that I could understand. That understanding only took place after researching over the period of many months.
I’m experiencing the same thing with glazing. After seeing the results of cone 10 glazing and seeing the depth that it creates I’m ready to take it on.
Cone 6 in oxidation just pales in comparison. It looks as if there is a film of glass on top of some clay. Sure some of it looks good but cone 10 just has something that makes it sing. It’s as if the glaze is a part of the clay itself.
I had previously bought chemicals for some cone 6 testing so I have a lot of 2 gallon buckets with a lot of the chemicals I need but cone 10 calls for some specifics. So I’m off to my supplier in a few days to pick up the rest of what I need.
I’ve made up some small pinch pots to test without fear of melting stuff to the kiln shelf. These will also be to test the creation of a black englobe to go along with the buff white clay body I’m using. I want to get 2 complimentary glazes, and with the color of the at body and a black englobe I will have a decent start for decorating and making functional wares with my OWN glazes.
I’m very excited to get some good reliable glazes:
