Has anyone tried using the recipe for the cone6 oxidation red glaze (goes by many names but is essentially the following recipe) that uses a frit rather than gerstley? If so, are you happy with it? I haven't run out of gerstley yet but I keep on planning to wean myself away from it and this is one glaze I can't do without.
Gerstley Borate 3200 Flint 3000 Feldspar--Kona F4 2000 Talc 1400 Kaolin--EPK 500 Iron Oxide--Red 1515
