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.
Previous Celadon glaze tests with incrementing FE2O3 from 2% to 12%
Testing the specific gravity of the glaze with hydrometer.
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?!
Just got John Britt’s new book The Complete Guide to Mid-Range Glazes: Glazing and Firing at Cones 4-7. I’ve got a lot of learning to do. Need to brush up on some math and chemistry. Hope everyone had a great Christmas and is looking forward to pushing on into the New Year. 2015 is going to bring great things.
