I can't stand it any longer. I'm tired of trying to guess whether a glaze
is in balance or not or if I'm mixing up a poisonous brew, etc., etc. Also,
I just like knowing the chemistry. Occasionally I do get out pencil and
paper and convert recipes to formulas, but it can be very time-consuming and
life to short. So, here's the question: where do I buy software that will do
it for me? I'm not on the Internet (I just have e-mail), so I can't
download a program.
Another question for the glaze gurus, is 6% vanadium stain added to a base
glaze fired to cone 6 too high to be food-safe?
Thanks,
Marjory

Marjory -- when you say "vanadium stain" are you referring to a Mason
stain? If so, the good people at Mason have led me to believe that
all of their stains are non-toxic and therefore foodsafe (this based
on a phone call I made to them just before Thanksgiving to check on
just this issue).
Happy 1998 all!

Mason assumes you are putting the stain into a glaze that has
adequate glass former and alumina and is properly melted. I am sure
you would not eat any of their stain powders, but if you put the
stain into an unstable glaze than that is what you are doing.
