I have gleaned the chemical names for Opal Blue Glaze, but haven't a
clue as to percentages. I haven't found this in the archives.
If anyone has this recipe and has the correct percentages I would
appreciate very much receiving that information......... and any
pointers in using the glaze.
Custer Feldspar
Silica
Gerstley Borate
Strontium Carbonate
Whiting
Add Cobalt Carbonate
Add Rutile
Thanks

Hi John,
This is what I had saved from a post on Clayart. Hope it is what you are
looking for:
Chris Schafale gave me this Opal Blue recipe, but I am not sure where it came
from. It is wonderfully consistent everytime.
Frit 3134 50
Kaolin 25
SILICA 25
COBALT 1
RUTILE 4
I usually mix it to the texture of cream and pour on two coats, just make
sure you do not get too much in the bottom or it will pin hole where it collects
at the bottom of the pot. Usually brushes on well also. I have also used
3134 40% and GB 10% to help brushability.
Wonderfully smooth shiny glaze

Veena -
Is this a cone 10 or a cone 6 glaze?

Veena, Thanks.
These numbers are what I was looking for.
However, I note that my version calls for Strontium Carbonate. Your
version does not. Can you account for the difference??
Thanks,
