Glass - Opalescent Green - COE 90

Use for fusing glass elements and art. Measures 2" x 3". COE 90 glass.What is COE and why is it important?

COE stands for "coefficient of expansion". To put it simply, as glass heats up, it expands and when it cools it contracts. The COE number tells us the rate at which a particular glass expands and contracts. If you try to fuse glass with mismatched COE numbers, the glass will crack as it cools. So, it's critical to the success of your projects that you use the same COE number for all the glass you are fusing in a project. But don't worry; we've made it easy on you! All of our glass products are 90 COE so they combine safely.
