Cast Glass Molds Will Produce
Excellent Fused Glass Jewelry

How cast glass molds holding glass frit and fusing glass are used to make jewelry and other fused art glass items.

Cast glass used in fused glass jewelry usually refers to glass frit melted in a mold.

There are many frit molds available for art glass jewelry. Mold designs allow many different styles to be made.

Jewelry can be made from glass frit, glass powder and small pieces of fusing glass combined in the same mold.

It is important to know that different size frit can produce different results.

Transparent fine frit will produce a casting, which can be very opaque. This is due to air pockets forming around the frit resulting in a large number of air bubbles being trapped.

As frit size increases the number of air bubbles decreases allowing more light to pass through the casting improving the clarity of the casting.

A combination of frit sizes helps to minimize the problem.

Like other fusing molds you should apply kiln wash to the mold prior to adding frit.

Ensure the mold is completely dry before using.

You also need to allow for shrinkage by adding a little more frit to your mold.

Use a brush to move frit away from the edge of the mold and mound it up in the centre of the mold. This will give a nice edge to your casting and minimise spikes occurring around the edge.

Colors can be mixed and added to your mold to produce a multi-colored jewelry item. Strong colors should be used sparingly as they may overwhelm light or medium colors.

Different colors can be poured directly into the mold or individual colors can be mixed with fuser’s glue and packed into the mold to prevent the colors merging with each other.

Care needs to be taken with dichroic frit as the coating sometimes burns off home crushed frit. The dichroic may also migrate through the frit as the glass becomes liquid.

Molds should be elevated on posts in the glass fusing kiln to ensure adequate air circulation during the glass fusing process.

Glass molds will allow you to produce a wide range of fused art glass jewelry such as cabochons, earrings,fused glass pendants and fused bracelets.
