There is a version of this glaze with tin:

the silica is different.
But I am an ultrox addict!

You can of coarse change the amount of the cobalt!
Notes:
FROM ^10

from a recipe of Ruth Ballou rballou@bellatlantic.net


The first time I made the original recipe, it tuned out in ^6 not mature,
beautiful light purple,pastel- like appearance.
You may find it in the archives.
Emily, can be a nice white, but ONLY white the magnesia kills all oxides
except cobalt!

I found out that if I use the "West & Gerrow" expansion of matrix give me
similar results to the expansion of Insight (for an easier comparing between
these two great programs!
