Hello Clayart!
The last glaze in my article, as I read it from the fax I have got:
Kaolin 30.5
Strontium carbonate 15.7
Wollastonite 18.1
cryolite 10.5
tin oxide 5
copper oxide 3
The silica was lost on the clipboard.
I tested this glaze. The numbers bellow were brought to 100% + tin and copper.
The new names tells all!

Silky shine when sprayed on white stoneware.
this glaze will slowly will take the place of Behrens's stony matte as I will learn to use

You can try it with 3 RIO instead of the copper. I will do it within two weeks
