base that crazes, Alisa
Kathryn,
I am a relative newby to glaze development. I
started by using MC6G. I liked the idea of
safety and want to be a responsible potter. I
learned a lot from that book and keep learning
from it. I bought GlazeMaster mainly to store
glaze recipes and thought, for 50 bucks it might
come in handy if I ever start a business. Now
every time I get a new glaze recipe, I enter it,
and then I check it based on the criteria in
MC6G. I figure if I start from there, I am on
the right track.
Later I tried making changes to a recipe because
I wanted to sub a frit for GB and test side by
side with GB to see the difference. I did the
best I could and then asked for feedback on this
listserve.
I also like it for batch amounts. I had 335g. of
epk, and I wanted to make the largest batch I
could given the fact that I was running out of
materials, so I was able to calculate the maximum
batch of my glaze with only a limited amount of
epk. I helped me out in a pinch and got me
through the holiday rush.
You can also enter prices on materials and
determine the cost of a batch of glaze. This
would be handy in a teaching situation, or
deciding if a problem glaze is worth fixing if it
also turns out to be pricey.
Silica/Alumina ratio just tells you whether a
glaze will be glossy or matte. Generally, a well
fired glaze with a si/al ratio above 7 will be
glossy. I know this because I looked it up in
MC6G just now.
You could download the trial version and see if
you find it useful. See what you can learn about
the glazes you are using now. The biggest thing
I learned is that mattes can be made by
underfiring, but they are not stable, and that
there are a lot of unstable glazes out there.
Instead of asking Ron and John on ClayArt, I can
refer to their book which is almost always
consistent with what they say here. Then I can
have better questions or do a test and ask how to
change something. I see it as an investment in
my learning process.
