Hi!
I tried to sub some materials in my S4b.
I failed but got nice results:
I got in both tests very similar results. Glossy shiny pale turquoise or green. In one of
the tests, where was thick was mottled ( in the imprints)
Here are both recipes for your use. I will rename the glaze according to the results:
They asked the bowman: "How do all your arrows are always in the
middle of the circle?" I shoot first and than paint the circle around"! Said the bowman!

I prefer the second one because of the lower cost

I will go on trying because I have only 5 K'g left of cryolite
I think a Currie grid out of Behrens's stony white/ green might help.
I am waiting to the pictures. When I will get them I will show them.
