Shipping costs for regular mail are based on the weight of the package. The shipping costs for Priority Flat Rate mail are fixed. If an order can fit in a Priority Flat Rate box, the cost is the same. It is most economical to fill a Priority Flat Rate box to full capacity.
To take full advantage of the Priority Flat Rate prices, consider ordering frit in the half jars, refills, or sample sizes. A small Priority Flat Rate box will hold 12 refills, 12 half jars, or 54 samples for $7.20 (US) $34.95 (International). (The standard jar is too tall for this box.) Shipping the same amount of frit to Germany, for instance, would take longer and cost $49.50 for regular Air Mail.

Val Cox Frit was established in 2002 and it was common to refer to the standard jar of frit as a 4oz jar. That's an average weight but not always accurate since each frit color weighs differently depending on the metal oxides it contains. For instance, blue tones tend to be lighter while pinks and purples tend to be heavier. In any case, having a rough idea of weight is helpful for calculating shipping.
To set the record straight, Val Cox Frit is sold by volume, not by weight. We fill the jar regardless of its weight. The standard jar is two inches wide and one and a half inches high and holds 1/4 cup, plus one level tablespoon of frit. The refill bag is the same amount of frit in a heavy duty ziplock bag.
The half-jar is half the size of the standard jar and holds half the amount of frit.
The sample bag holds one level tablespoon. The average weight of the sample bag is one ounce, or about 25 grams.
All of Val Cox Frit is made with premium furnace glass (96coe). The metal oxides that give furnace glass its intense color also make it more elastic. This means that Val Cox frit is compatible with Moretti/Effetre/Vetrofond (104COE) and Bullseye (90COE) as long as you use it in moderation. A conservative rule of thumb is 5% of the weight of the bead. This rule of thumb works to your advantage in your designs as well. Since furnace glass colors can be intense, applying a small amount not only works best but looks best.
A note about the color orange
The yellow and orange colors do not contain lead, which normally makes furnace glass more adaptive in coe. If you are working with Moretti (104coe) or Bullseye (90coe), work this color on the surface, instead of encasing, to avoid cracking issues.
Orange will become black where it comes in contact with silver foil.
