Here here, Cheryl! While reading David's post, I was thinking of a
response, then read yours -- exactly what I would have said. The
analogy of assembling a very complex jigsaw puzzle without being able to
see the picture and being handed a piece at a time works for me!
I finally feel that I have a handle on unity formulas, and the effects
different oxides have on glazes, but I still struggle with the
coeffecient of expansion, silica:alumina ratio, effects of time and
temp. on these, and probably a couple of more things (at least) that I
can't think of right now. Between Clayart and my glaze software though,
I am beginning to be able to ask myself, when I see a glaze formula,
what would I guess this would look like? Why? How stable would it be?
How safe is it?
What I haven't figured out yet is an organized set of questions to ask
about a glaze formula, and what to do with the answers I might get.
That's what I'm working towards.

Jon , you want some questions? I have 25 years of glaze trials that are
almost right. When I have time I tweek one this way or that, guessing from
the discriptions of the reactions of chemicals in Carlton Ball, Nelson or
Keramos. I'm hoping one of the glaze programs will shorten the amount of
testing.At the rate I'm going now I'll be very old before I solve even a
few of my puzzles. In all this time I have tested 100's of glazes or
variations and it may be just dumb luck that I have 8 or 10 glazes that I
really like. Here's a toast to the software designers. I just want time,
more time to study and learn.

Ok. I have to put my two cents in here just to send a vote of appreciation
to all you glaze calc types who contribute to Clayart. I don't want you all
to stop sharing because you think you're unappreciated.
I have taught both Clay and Glaze Calc at the graduate level. After I had
tortured my students with unity, and memorizing materials, milliaxial blends
and all the other science magic, they were aghast to see me go into my studio
and start throwing a little of this and that into a bucket practicing my own
intuitive form of glaze development.
One of my best friends does wonderful work using what she calls "room temp
glazes"-nail polish. Her work is genius.
Bottom line: knowledge is power. Do what you have to to fulfill your vision
and lighten up on others who have found a different path.
