Glaze request.

Mamo glaze outside, subtle iron glaze inside.

Green (no copper) glaze request.
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.
