Dear Crazy,
Relax.
My suggestion is to forget the digital scales. Why worry about buying
batteries and things breaking?
An Ohaus triple-beam balance will last basically forever. Mine, that I
have used for the last 25 years, was made in the 1940's or '50's.
There is no reason to own two scales unless you just want to.
That said, if you still want to go digital, scales with .1 gram accuracy and
1200
gram capacity would serve you well. .1 gram is plenty accurate.
The only beam weight I have and use on my triple-beam is the 500 gram,
so my capacity is 1110 grams. This means for a 10,000 gram (5 gallon
bucket) batch of glaze I may need to weigh out the feldspar in 3 or 4
lots - quite reasonable. The weighing scoop wouldn't hold much
more than that anyway.
You can also find triple-beam balance scales used and for sale cheap.
Police and sheriff auctions are good places to look because they confiscate
them from drug dealers.
Last month I found a nice one in a junk store for $15. It was used in a
paint factory, as evidenced by the paint drips on it (which cleaned off
with a rag dipped in Gojo hand cleaner).
I will keep it, and my antique model will be going to Waco, to live with
Taylor.

OK-I know this has been discussed. Please bear with me...I need to order
quickly. Melsan has suggested I get a digital scale. I like the idea.
However, I am looking at "My Weigh" (good price) and to get a .1g
capability, the higher numbers on different models range between 250-1200g.
Will a digital scale with a 1200g-.1g capacity be high enough? Probably
will never make more than what will fit in a 5 gal. bucket. What if I
bought a small digital with a 250g-.01 capacity and a triple beam 2610? I
have searched the archives and have not seen this suggested. I won't be
weighing clay components, just glazes.
Don't want to bother Melsan with this as he has already offered to fly down
here and delete all my triple posts. What a sweetheart!
I am down to the wire now. Wheel is in place, shelves are up, kiln is on
its way, chemicals will be picked up Friday....I am going full time as of
April 1st.
Call me crazy...

My suggestion: by a small digital gram/ounce scale to measure chemicals =
for small test batches where accuracy is extremely important. Then use =
either a triple beam of otherwise less accurate scale for large 5-gallon =
size batches where the decimal points are not as critical. It all =

needed for other equipment. Restaurant suppliers usually are a good =

Good luck,
Jeff

Dolita, Here are the numbers to consider. 500 grams = 1 quart, 2000
grams = 1 gallon, 5000 grams = 2.5 gallons, 10,000 grams = 5 gallons
From these you can see what you will be measuring for a recipe. For a 5
gallon bucket you are likely to be weighing 2,000 grams.

Dear Dolita,
Regardless of your choice of digital or mechanical, consider the
following factors;
What is the largest batch weight you envisage. Are you going for One
Kilo batches, five or ten kilo batches and will you be making small
sample batches.
The second is accuracy. If you will have a need to make small test
sample batches then you need an accuracy of say, for example only,
plus or minus one tenth of one percent of batch weight. So in a 100
gram batch graduation to "zero point one" (1/ 10) of a gram will not
be sufficient. you need to be able to weigh to 50 milligrams.
But if you are making one kilogram batches, balances which are
graduated to one tenth of a gram are ideal.
I have three systems. First and favourite is the good reliable old
O'Haus with a tare device which gives me the advantage of
accommodating different material carriers. The second is a Soenhle
domestic beam style weighing to 15 kilos and graduated to 5 gram
increments. Finally I have an apothecaries beam with weights as small
as 10 milligrams for weighing colorants for 100 gram test batches.
And, as a little favourite which will never be contaminated with any
grit I have a set of Indian Carat Scales weighing to one point 1/500
gram
Perhaps, when the new server is up and running we should have a
cooperative investigation into the merits of various weighing machines
and devise a tutorial of instruction for the archives.
Good luck with everything on the First of April.

The ideal would be to get the small digital scales with the 250g-.01
capacity for tests and a MyWeigh UltraShip 50 for larger batches. This
larger scale weighs up to 50 lbs! and is fantastic for the 5 gal batches.
It has a precision of 2 g. which is not good enough for 100g batches, but
plenty good for 5 gal batches. It is a bargain at about $55 from several
different sources. I got mine from www.oldwillknot.com and have been
pleased. If you try to get by with one scales, it will be difficult with
digital scales... a 1200g capacity for mixing 5 gals (10,000 grams) will be
slow.
