Jesse’s Gold Crystalline Glaze (Silver Nitrate)
Here’s the Silver Nitrate recipe published in Clay Times Nov/Dec, 2006:
Fusion Frit 75: 51.5
Zinc Oxide: 23.5
Silica: 22.0
Grolleg: 1.0
Calcined Alumina: 2.0
Add:
Titanium Dioxide: 4.0%
Silver Nitrate: 5.0%
Cobalt Carbonate: 0.5%
MAGMA Binder: 0.3%
I have since stopped using Silver Nitrate. You can read more at the post: Using Silver (Ag) as a colorant in a ceramic glaze.
This piece is a heavily reduced Silver Nitrate and Cobalt glaze. Upon my return, I accented it with a low-fire enamel and antiqued gold leaf. The image barely shows it, but the crystals actually have soft streaks of red, purple,and blue.
The pedestal was glazed with black gloss and crackle glazes alternating within the successive rings. Gold leaf and low-fire glass enamels decorate it as well.
Hi jesse:
I read your post #4326 on post fire reduction and it was thought provoking.
I know I told you that I was going to fire my pots in a Glo Bar kiln to try and
get some reduction in the crystal. I have not done this yet.
Why? I’m slow I guess, but the question I have been asking myself, was the one you spoke of in your post and that is how long should the smoke stay in the kiln and how much? I have read Diane Creber and Peter Ilsley book and this was not spoken of. Diane said that poking holes through some fiber she placed under her lid helped the smoke travel through but how large of holes is she speaking of ?
In the end I guess it’s just test,test,test ? Could you speak more on this. Thank You Chris
P.S. The work you sent to Germany looks great.
