here is a simple bit of math.
(old information, but worth another look.)
.0022 X grams
so.
7000 grams is:
15.4 pounds.
round that to fifteen and half pounds and
you can use that old baby scale.
i have changed all my glaze recipes...(note i say recipes) to pounds.
i have a good store scale. add a bucket for tar
and turn back the spring.
i own a good triple beam scale and a digital scale.
( i have a roll of solder that is the exact weight of my large
plastic pail. perfect tar. just hook it on the end of the beam.)
if i had to measure out perfect amounts of cobalt, i would
use the digital. if i was doing a perfect/do it right experiment
i would use the triple beam.
i use them all. just tools as lilly says.
but for 5 gallon pails of standard glazes i use pounds.
for that 50 gallons of rhodes 32...often a full bag.
as i said the other day...a bag of gertsley was 40 lbs, a bag
of volcanic ash was 60 lbs...dump them in, add water and some
zircopax. glaze
it all depends, if your brain makes you crazy because you think
you have 5 grams of feldspar too much...well, use a digital.
i find that years of experience with standard glazes allows me
to have a little bit of flexibility.
like watching `mrs. rankin` making quilts. hands slowly making
stitches, colors that make you cry....all hand done. no science or
technology, just scraps of cloth...string quilts...`just to keep the
babies warm`. wood workers with hand tools. rubbing oil
in hand made furniture. weaving baskets. hand work, craft,
a perfect relationship of hand, eye and mind. humans, making
pretty things...for every day use. i am so glad i am a member of that
society. and the only dues you have to pay are.....keep it going, love the
work, pass it on and never give up your values....`hand made`.
