How to make your own glass frit (and frit combinations) using any COE glass.

1.  To make sure your glass is all the same COE, use a Fuse It Test Card. 

A convenient and money-saving device that tests the compatibility of glass. Cut a 1 1/2" section of clear glass (of a known COE) and a 3/4" square of the glass you wish to test and fuse together. Sandwich the fused glass piece between the two layers of film above a bright light. If there is no halo around the glass, the two glasses are compatible. If a light halo is seen around the glass, this signals stress within the glass and incompatibility.

Use this test card when you are not sure of your glass compatibility. Now you can fuse bottle glass, including wine bottle glass and recycled glass easily with this card! Create imaginative recycled glass art by using this test card. An excellent tool for multiple melted bottles to shape and use in glass molds. If you have fusible glass laying around (or you were given fusible glass), but forgot which COE it is, you can easily test it's compatibility with this cost efficient tool.

2.  use an Aanraku Frit Maker

All steel glass crushing frit maker.
Includes instructions and rare earth magnet.
Overall height: 11-inches.
Piston diameter: 3-inches.
Chamber depth: approx 5-inches.
Weight: 7.2 lbs
Welded steel
Use for making your own lampworking glass frit and also fusing frit. Create your own color combinations and sizes.


We know that this is not a new tool, but it is a must have for lampworkers and fusers!  Use your lampwork rod pieces and shorts and other rods (maybe ones that are shocky or too thick to use easily), to create your own glass frit and glass frit combinations.   It's just another great way to use up those rods that are just too short to hold anymore.  You can do the same thing with glass fusing.  Take those smaller pieces of fusible glass and make some of your own frit.  Be sure to always use the same COE glass when creating frit and using it.

3.  Finally, use a set of Frit Sorters to sort your hand-made frit.
Includes 4 galvanized nesting steel cups with stainless steel sorting screens.

Bottom cup 0.20mm, fine mesh Stainless steel
2nd cup + 0.20mm 1.20mm, mesh Stainless steel
3rd cup + 1.20mm 2.70mm, mesh Stainless steel
Upper cup + 2.70mm 5.20mm, mesh Stainless steel

Cups size: 6" diameter, 4" deep. 

Use these different sized sorters to allow for you to use powdered frit for delicate fusing and lampworking to large chunky frit for a different effect.
