|1. Pharsalia Green then...|
Something in one of the ingredients, you say? I checked... I made a new batch just in case I had made a mistake... nothing... I can't get back to my old Pharsalia Green no matter what I try!

Another glaze that's breaking my heart is the old Randy's Red. I got that recipe so long ago that I can't even remember when or from whom. But it was a beautiful, reddish brown glaze that broke to blacks and golds. Now it's just a mucky old brown with nothing happening, no breaking, no gorgeous color, nothing... Here is Randy's Red before (photo 3) and after (photo 4).
Both of these glazes have Gerstley Borate in the recipe. The Pharsalia glaze has 10% and Randy's has 31%... They also both use soda feldspar... 30% for the green glaze and 20% for Randy's Red.

The one thing the failing glazes have in common is that the raw glaze on a pot feels dry, rough, thin rather than powdery and smooth.
A sad state of affairs...
Fortunately, in the meantime I have been experimenting with glazes from the Mastering Cone 6 Glazes book and have got great results with slate blue, oatmeal, and spearmint... and now with the new Selsor yellow.... I think I'll just forget about the old glazes.
