the readout in mine is hard to see now because some powderyness has
infiltrated the digital window. So I'd check that the scale is pretty much
dustproof or sealed; also that it can be plugged in rather than only run on
batteries.

Does any one have thoughts or recommendations on use of
electronic scales for glaze ingredients?
How does the accuracy of modern electronic scales compare to
traditional balance beam scales?

I have never used them in the studio, however, I have managed a number of
restaurants in my past life and we constantly had to have them recalibrated.
problem was food particles throwing off the calibration.

I bought an Ohaus Digital CS200 one for $68.00 that is great
for mixing up test batches - it's precise to 0.01 grams
I bought in on-line from balances.com
Now, the problem is when you go to mix up REAL batches
(like 10lbs) worth of glaze.... it's a pain in the butt
to measure out the everthing in 200g portions.....
thanks,
Connie

Dear Bob,
I have electronic scales and like them very much. You have to choose between
volume and accuracy, however. My scales will weigh up to 1000 grams with 1 gram
accuracy. You can get finer accuracy, but you'll pay a premium for it and the
capacity will go down. I chose this scale over one which offered (if I remember)
5000 gram capacity with 2 gram accuracy because I wanted the scales to be able
to accurately weigh sensitive ingredients such as cobalt oxide. As you can see,
this is only useful for test batches and for low-weight ingredients of large
batches. If you want the specifics on the scales, and lots more info, do a
search of the archives (link is below) for scales. I don't remember all the
buying info, etc. It's in my paperwork somewhere, but you should find it easily
in the archives.
Best wishes,

Although electronic scales will most likely be more accurate, I don't think
that absolute accuracy is that big of an issue. I can measure 0.1 grams with
my triple beam balance and, aside from maybe small quantities of a copper
red recipe, I doubt that there are very many things in pottery that require
that sort of accuracy.
On the other hand, an electronic scale will give you a direct numerical
readout of the weight, reducing the likelihood of an error in summing the
position of the poises on the three beams (plus any added weights like the
kilogram weights). Now that kind of accuracy does matter to me.
The electronic scale most likely will have a switch to allow you to change
the display between grams and ounces. Fewer conversions -> less chance for
error.
I suspect that an electronic scale will settle faster (though I'm not sure)
which should reduce your weighing time. If nothing else, it's giving you a
continuous readout as you add material, so you can see how quickly you are
approaching the desired weight. With balance scales, you don't know that
you're near the desired amount until you're almost already there.
Experience* with a balance scale will minimize this, but I think that the
electronic scale would still have the edge.
Be careful to check the capacity of the electronic scale. You can get a
wonderfully accurate scale, but if it has a capacity of 100 grams it will be
next to useless for weighing out pottery materials. You need at least a
kilogram capacity and it would be much better to have 5 or 10 kg.
Don't know if that helped, but it's some things to think about.
Bruce "always a little out of balance" Girrell
*As you gain experience with a balance scale, you learn to keep bumping the
pan with one hand to test how close to balance you are. As you approach
balance, you will feel - and eventually see - the difference when you bump
the pan.

I can't speak to triple beam scales for ceramics (been too many years since
I used them for, uh, other things) but I bought an electronic scale on Ebay
that weighs up to 15lbs and have no complaints. It weighs in ounces,
pounds, grams, and kilos. It also has a tare button so you can zero out the
weight of your container. It is small and runs on batteries.

I use a triple beam Ohaus in the pottery for glaze making and an expensive
digital Ohaus in the kitchen to weigh out food for two children on rigorous
medical diets. The kitchen one is good to 2000gm and weighs in 1 gm
increments. It has been replaced (graciously and quickly) by Ohaus twice in
the past 18 months even though this involves mailing replacemtns to me in
Dubai. Yes, the digital one is fast and easy but it does not strike me as
being very robust. Accurate, yes, able to last for years, no. Your mileage
may vary.
Best regards,
Carol

I bought an electronic scale for 30 bucks off ebay. Off brand, made ?, but
works great. I also have a triple beam that I bought at an antique
dealer..already had clay all over it so you know what it was last used for.
Triple beam can get really accurate (tenths). Electronic to 1 gram. Once
in a while I use the triple to double check the electronic. Tare feature on
electronic and gram/ ounces/pounds& ounces works super. The tare is
especially useful to mix out test batches in whatever container you can
reach. Lots of opportunity to double check you didn't forget something
checking total weight in another container. It's easy to use different
plastic containers to weigh out each ingrediant. FAST
Best of all it goes to 10 lbs. I mix 25-50lb dry glaze mixes for production
and it goes really fast. I could never do that on MY triple beam...because
of its small size(no poly scoop-just tray).
I used my electronic scale last fall for IAN CURRIE glaze workshop. I
weighed out material and got to check it on several brand triple
beams...each had a degree of operator error-takes some familiarity and two
people often line up the marks a bit different. Still, 300 gram batches
stayed +-1gram.
Of course batteries and when to know it's failing? But, I do have triple
beam to double check.

The only problems I've seen with one of these electronic scales is that a.
they don't seem to sense small amounts of things like a triple beam will,
and b. if the batteries start to go, the weights will not be accurate. If
you're gonna use one of those, get an AC adapter.

I have had considerable experience with all types of mechanical scales,
includeing the very accurate ones. That may be my problem, but I don't
think so. I recently bought an electronic scale from Runyons in Michigan,
and have regretted it. It just don't seem to work correctly. It does have
aa tare feature, that lets me tell the scale, that I am weighing a
container, therefore to reset temporarily to 0. When I add glaze
ingredients gradually, it doesn't change. If I put weights on, it measures
them correctly. It wasn't worth messing with, so I stored the scale, and
haven't spent a lot of time trying to figure out the problem. Bob Dye

You get what you pay for. Electronic scales used in industrial labs and in
the chemistry labs at the College where I taught are reliable, accurate and
dependable.Do not be fooled by the .1 increments on a triple beam balance.
They are not accurate to a tenth of a gram. You have to calibrate them in
order to know the exact accuracy.

Bob-
I really like using a digital food scale to weigh glaze ingredients. The
brand I have is a Terraillon Electronic Food Scale. Bought it at a gourmet
kitchen wares store about 5 years ago, and it's been very reliable. I don't
know if this brand is still made.
The "TARE" feature is excellent zeroing out the scale with a plastic bowl or
other container to measure ingredients. My scale is accurate to 1/8 of an
ounce (no grams feature.) I found that 100 ounces is a good, small glaze
batch size for me (~6 pounds dry glaze) for a 5 gallon bucket. 300 ounces
(~19 pounds dry glaze) is a good larger batch size for a 10 gallon bucket.
I use the Ohaus triple beam balance for 100-gram test batches.
