| Mamo glaze outside, subtle iron glaze inside. |
Trading for Mamo glaze below.
I made a full batch of glaze that was supposed to be a subtle green.
I was so sure I knew how to make a green glaze (oxidation atmosphere) with iron oxide (no copper) that I didn't test it before using it on a desired piece.
I understand the basics. Alkaline glaze should make iron green instead of brown.
So I simply replaced potash feldspar with soda feldspar. Didn't come close.
So now I have to do some research and many line tests.
Hoping you can give me a head start with an iron oxide (no copper etc.) cone10 ox. glaze.
I'll trade you my favourite Mamo glaze.
Cone 10. Oxidation.

Hi Andrew, can't help you myself but if you are on Facebook there is a page called Glaze & clay Recipe Sharing. Mostly USA but might be useful.
Just had a quick squizz in Janet De Boos

she says add 3-4 parts - changes the glaze to a greenish honey colour.
I've used it a few times and it's a sort of dirty green (nothing like a copper green). But might shed some light on your test
Gorgeous bowl by the way
