Hello,
I have always worked in grams.
2,000 grams or 2 kilograms of dry materials
give about 1 gallon of liquid glaze base depending.
on the amount of clay used.

You certainly don't have to work in grams, and the quantities given in
UMF recipes do not imply any specific units. For example, if a recipe
calls for "Custer Feldspar-----50", the 50 units can be any unit of
weight you wish, be they grams, ounces, drams, pennyweight,
doppelzentner, shekels, whatever. You don't even need to stick with
the 50 (or whatever) specified. One can divide or multiply the number
by anything, so long as the same operation is performed on all of the
quantities. For example, you could divide all of the numbers by 4, or
multiply every number by 10, and the formula is still the same.
If you wish to work in even more obscure units of measure, this site
will prove useful: http://www.weirdconverter.com/weight.php . For
example, one pound is equal to 16 human eyeballs, and one kilogram is
equal to .004 baby grand pianos.
The reason grams are used is because they make the math very simple.
You have made life a tad more complex for yourself, but it is
certainly no disaster. Let's say you wish to make a 1000 gram batch
of glaze, a quart or so, which is a good quantity for a small scale
potter. 1000 grams is about 35 ounces. Since your UMF totals 100,
you could just divide every quantity by 3, then call the units
"ounces". This will give you a 33 ounce batch, which is within
spitting distance of your 1000 gram target. Your 50 units of Custer
spar called for in the recipe is now 50/3, or 16 2/3 ounces. Your 6
units of RIO is now 6/3, or 2 ounces. Not so tough, and as Douglas
Adams so generously advised, DON"T PANIC!
Good luck with your glaze project.

Don't know what kind of scale or what mix of gram and pound weights you hav=
=3D
e
or even how large of batches you want to mix, but you can probably weigh
chemicals out with what you have. Just remember: 454 grams equal 1 pound.
If you don't have enough of smaller gram weights, perhaps you can find the
other gram weights on ebay also.

1 gram =3D3D 0.0352739619 oz. Can you make an Excel spreadsheet with this?
You can send me the recipe and I can make a spreadsheet for you.

You could re-sell the pound scale on eBay or Craig's List, keep the gram
weights, and buy another scale that is metric.

James is correct. There really isn't a need to convert grams to pounds
or pounds to grams in most cases. If your scale is pounds/ounces
simply and the glaze calls for something like 50% ball clay then you
would simply use 50% of the total batch size in pounds or ounces. If
you make a 10 pound (160 ounces) batch of the following glaze (a white
crackle raku)
Gerstley Borate 65%
Neph Sye 20%
EPK 5%
Silica 10%
You come up with, in ounces:
GB 104
NS 32
EPK 8
S 16
No need to convert to grams at all.
For a rough guide a 10000 gram batch or full 5 gallon bucket would be
about 22 pounds of material. 22 x 16 =3D3D 352 ounces
