My JB1 glaze is peeling off.
It peels off after it has dried on the pot, before firing.
I spray my glazes.
I also tried to spray my pots with water to wetten it a bit, but the =
problem isn't solved.
This is the recipe!
42.8 Soda Felspar
4.8 china cly
1.9 lithium carbonate
1.9 bentonite
16.2 whiting
4.8 zincoxide
22.8 quarts
4.8 titanium dioxide
1 cobaltcarbonate
I use a stoneware claybody bisque at 950 Celcius ( 1750F ) and I always =
use some wallpaper glue in the water, I use for my glaze.
It seems to be the glaze recipe,but can't find the problem.

Hi Cor,
Let me know what kinds of ball clays you have or can get - if you are not
in North America - I will need the analysis as well.
