A COE compatibility test is a test in which two types of glass are fused together, and the compatibility is verified by observing the distortion at the interface using a polarizing filter.
Since glass with mismatched coefficients of thermal expansion or viscosities causes stress at the interface, it is possible to determine before firing whether the glasses can be mixed.
