1. How big a scale do you need?
Pick a scale that matches the maximum amount you will weigh. This has to include the bowl or cupthat you use to hold your materials. Typical amounts of glass for various projects are:
Earrings, pins, pendants, magnets: 5-25
grams
Bracelets: 50 - 100 grams
Small boxes: 75-150 grams
Small animal forms: 50 - 150 grams
Small plates: 300 - 600 grams
Dinner plates: 500 - 800 grams
Bracelets: 50 - 100 grams
Small boxes: 75-150 grams
Small animal forms: 50 - 150 grams
Small plates: 300 - 600 grams
Dinner plates: 500 - 800 grams
Production runs can involve larger amounts, and a parts counting feature may be nice to have. For example,
you may know that a glass heart weighs 6 grams. You can program the scale to record in increments of 6 grams, so it tells you when you have enough for 22 projects, without you having to do the math.

2. What do you want to weigh?
This will affect several things: the size of bowl or tray, the units you weigh in, and the required accuracy.Powders are pretty fluffy, and require a bowl or cup to hold them. Some scales come with built-in expansion trays, but remember that the capacity of the scale includes the weight of the tray. For most jobs we use the disposable plastic storage containers that you can get at the supermarket, since they are big and lightweight.
Depending on what you weigh, you may find some units of measurement to be more natural than others. Grams are the universal metric standard, but many materials are sold by the pound or ounces. There are also specialized units: metalsmiths use Troy ounces, goldsmiths use pennyweight, pharmacists use grains, and gemologists use carats. Pick a scale that will let you use your favorite units, and you won't have to do the math yourself.
Accuracy is usually a function of the size of the scale, and quality of the electronics. Most scales divide their working range into between 2000 and 5000 parts. For small scales this equates to an accuracy of about a tenth of a gram. Accuracy becomes more expensive as the scale gets larger. Of course, if you are weighing individual diamonds, you will want something more accurate (and expensive) than anything we currently sell.

3. Do you want a portable scale?
I like portable scales, because I often use different places as my workshop. And let's face it, the PalmScale 5.0 is a fashion statement as much as it is a scale. However, a portable scale has some disadvantages. They are easier to drop, easier to lose (in my house, anyway), require batteries, and don't have the capacity of fixed scales.Back to top
