Here is a formula I found for granite. Just know that this can be quite
variable and use this as a starting point:
SIo2 70%
Al2o3 14.5
Iron 3
Potash 4.5
Baria .05
Titania
Phosphorus
I think the following are cone 9-10 glazes. I haven't had time to run them
through my glaze program.
David Frith Pale green Celadon
White Granite 30
Cornwall Stone 30
China clay` 20
Quartz 10
Limestone 10
