" Glass Types, you've got it!"

Fusing glass comes in a variety of different types of glass that can be used for fusing projects.

For each project, you will want to be sure that your glass is compatible .

If in doubt of the compatibility, do a compatibility testing , or purchase glass that has been tested compatible .

Pick a particular COE of glass to use in your fusing projects and stick with that COE.

Everyone has their own opinion on what glass is best.

You can’t mix different brands of glass, so if you do purchase other COE’s keep the different types separate in your studio.

Be sure to mark the glass with the COE so that you don't accidentally mix the pieces.
