What is coe90 glass?
A Coefficient of Expansion (COE) is simply a measurement of the rate that glass will expand and contract when it is heated and cooled. To fuse multiple pieces of glass together, it’s important to use glass that is compatible. The two main COEs for fusible glass are 90 and 96.
Can you use any glass for fusing?
You can always use fusing glass in a regular stained glass project, but you do not want to use regular stained glass in your fusing projects. If you also choose to try fusing glass with other COE numbers, you will need to keep that glass separated from the 96 COE glass. Clear glass is used in many fusing projects.
How do you find the COE of a glass?
Two methods to determine the COE compatibility: Simply fuse a small piece of glass and then examine it by sandwiching it between two strips of polarized film. Compatibility testing can also allow you to identify more glass colors and textures from a stack of unidentified glass.
