That is pretty uncanny. I am trying to create a glaze very similar to this one, but at cone 10. We had one like this in the Santa Monica Potter's Studio 25 years ago when I was just beginning my adventures with clay. I have your book and just mixed up a test for haystack orange; hoping it would be similar. (Haven't fired it yet.) Would you mind reposting this glaze with a cone 10 formula? Thank you very much and thank you for your wonderful book!

I am going to go out on a limb and suggest this one:


VC Matte Cone 10
24.2 Nepheline Syenite
24.2 F-4 Feldspar
15.6 Silica
9.0 Whiting
11.1 EPK
11.0 Gerstley Borate
4.9 Lithium Carbonate

10 Titanium Dioxide

Let me know if it works. Titanium can be more or less. Remember the Colorants and stains.
