If you have a hunter green glaze I need to have some information about what
kind of glaze and what colourants to use - this is for cone 10 oxidation
but it will also help if I can see some for cone 6 as well.
Please email to me directly at
ronroy@total.net
I will not publish or use the recipe - I will - if requested - give my
opinion about durability and will also try to fix any problems - if
requested.

I have settled on:
.90% cobalt carbonate, and
1.80% chrome oxide
as the best colorants for a deep, dark, and rich hunter green.
Here are a couple of good ^10 glaze bases. I fire in reduction,
but they should be about the same in oxidation.
This is a pretty ordinary base. Balanced fluxes, high in alumina,
and low, but still within the limit formulas, in silica:
Minspar 200 feldspar 46.0
EPK kaolin 21.5
whiting 10.5
flint 9.0
Gerstley Borate 8.0
talc 5.0
+ cobalt & chrome to give hunter green
This is a high magnesium base, with alumina and silica within,
but on the low end, of the limit formulas Also high in boron:
Custer feldspar 25.0
Pemco Frit 926 12.0
Gerstley Borate 12.0
talc 13.5
dolomite 4.0
EPK kaolin 13.0
flint 20.5
+ cobalt & chrome for hunter green
Ron, I hope you will comment to the whole group if you have any
insights in making hunter green glazes.

Thanks David - yes I will do comparisons and publish them to ClayArt.
