hi Jacob,
Ash glazes at ^ 6 is part of my "to do" pile but I did make one two years
ago with ash of unknown origin using a recipe I read on Clayart.
Val Cushing's ^6 Ash Glaze -Oxidation
50 Wood Ash
20 Gertsley Borate - I subbed F-3134
12 Whiting
8 EPK
10 Silica
2% Bentonite (needed for 3134, not needed if using G/B)
I used it over Xavier's Warm Jade Green and got silver rivlets with
crystals. It definately melted and inattention with one pot neccessitated
the hammer just to get the pot off the shelf.
Start experimenting.
Best regards,
Carol

Carol, when you use an ash glaze, especially with unwashed ash over another
glaze, the "running" should necessitate putting something under the work - I
would recommend used and beaten up softbrick. It saves wear and tear on the
shelves.

When our school went to ^6 we developed a number of ^ 6 ash glazes.
Email me off list if you want them.
