some of you should turn away, this will
make you sick to your tummies.
i make glaze this way:
i look at the recipe. calc it by .0022 to get
grams to pounds.
i have an old grocery scale, it has a tar bucket
on it.
rhodes 32
11 pounds of feldspar
5 and a half pounds of dolomite
5 and a third pounds of china clay
3/4 pounds of whiting.
double if busy.
add silica to taste for shine/and toughness.
add a handful of rutile.
add water from garden hose til it looks good.
mix with a canoe paddle.
sieve with a long poled strainer. this also
aides the stirring.
put on pots. three different coats.
fire/sell to people.
always looks the same.
if you change the iron rich clay at all...you lose it.
looks bad.
clay is very important to what a glaze looks like.
i have never once worried about moisture content
of a glaze material. almost 50 years...never once
thought of it. the glaze works fine.
i spend a great deal of time thinking about pots, shapes.
color/painting on design/textures. and spend hours designing
on my wheel. `what does this one look like...opps/crap/out you
go...` come back some other day.
potter/hand skill/hand work/thinking skills.
a person that makes things with their hands and mind and
i suppose we could add heart. but, i know about hands and
mind. the heart part is very abstract.
keep on track
be a hand craftsman.
if you `annalist` everything til the life is wrung out of it
you lose.

Hey, Mel, I can almost match your method. I calculate mine into pounds and
ounces as well. However, I have an antique balance scale with a nice 12"
pan on it to hold the large amounts of materials. Then I use the heavy
weights that came with it. Since there is no vertical arrow to indicate
balance, I just eyeball the ounce bar. I also never knew or thought about
the wetness of the materials. It works every time for me as well. I make a
washtub full of glaze at a time, sometimes 70-80# total. I put hot water in
my first bucket as the materials seem to slake better and since I also add
CMC, it also dissolves that material more quickly. Only have to stir this
glaze once before the session after it sits between glazing days. The CMC
also hardens the glaze so that I can paint on top of it.
Regards,
Bonnie Staffel, where in Charlevoix, the next week will be sunny and warm.

there are a few tricks that old potters know well.
when you make glaze, turn off the phone, close the door,
tell people to leave you alone for an hour. THEN TURN OFF
THE RADIO,TV ETC.
make a big list of the ingredients on big paper.
like
SILICA 2,456 GRAMS _______ with a check box.
measure the silica, dump it into the bucket...make a check mark
in the box.
FELDSPAR 3,468 GRAMS ______ DO THE SAME THING.
and right down the list.
and those that make big batches, do the math and use pounds
FOR YOUR STANDARD GLAZES.
so many things can go wrong when you are making glaze.
error is compounded by loads of bad pots....bad firings...and
it takes time to find out what you did WRONG.
if you have a problem glaze...TOSS IT OUT.
start all new. you will never fix it with more materials.
glaze is cheap...bad firings are expensive...and wasteful.
you know my mantra.
won't throw out an aluminum can, but will fire the kiln
five times with bad glaze, bad kiln, and never blink. global
warming is caused by stupid potters that do not fire well.
do not mix glaze well..make HUGE mistakes.
DO NOT LET OTHERS BOTHER YOU WHEN DOING PRECISE
MEASURING.

Ooooooor, one could just pit fire pots and use tool dip on the inside.
Mel, got a 13 inch bud vase for you. Yellow tool dip insides, mouth
like a trumpet, heavy as a boat ancor.
Clothe your pots in atmosphere.
