There are varieties of stone defects that can arise from glass production.The use of polarized light microscopy can initially determine the type of glass stones,but the sample processing is inefficient and the composition of the stones cannot be specifically analyzed by this method.The siliceous crystalline nodules,aluminum refractory nodules and zirconium refractory nodules are taken as examples for analysis using scanning electron microscopy and energy dispersive spectrometer,which can quickly identify the type and determine the composition of glass stone,then infer its formation causes.So this method can adjust production timely and accurately and solve the glass product problem.
