All Val Cox Frit is shipped from this 198 year-old farmhouse in Vermont. To calculate shipping costs from Vermont to your address, visit the US Postal Services site.

The cost of shipping is based on weight. One way to save on shipping is to take advantage of USPS Flat Rate shipping. You can pack a lot of frit in a small Priority Flat Rate box; specifically, 12 refills, 13 half jars, or 54 samples. 

If you have any questions about shipping please ask me about it. 

Nitty gritty on weights and measures

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 and 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. 

COE Compatibility

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) 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 designs as well. Since furnace glass colors can be intense, applying a small amount not only works best but looks best.

Be Superficial.

Generally, the yellow and orange tones are not as elastic as say the pinks and purples, so if you are working with Moretti (104coe), work these colors on the surface instead of encasing to avoid cracking issues.

Orange is the new black.

Orange will become black where it comes in contact with silver foil.
