Mel,

I will try sending this again. Last time I hit some key by accident before I
was finished typeing and it went out by mistake.

This glaze is called Ember-glow. I developed it for use in cone 10 reduction
but It may work for your purposes in oxidation as well. It develops lots of
patina and character.

3-1/4 pounds Barium Carbonate
15 pounds petalite
2 pounds neph sye
2 pounds epk

add

4 ounces red copper oxide
12 ounces copper sulphate
1 tablespoon sodium silicate syrup
several drops of dishwashing detergent

Good Luck

Tony
