PROBLEM TO BE SOLVED: To provide a method for identifying a glass defect source by which the glass defect source is directly identified without using a mathematical simulation. SOLUTION: The method for identifying the glass defect source has steps of: structuring the glass melting furnace using the melt-cast refractory containing at least a tracer component of one kind selected from among Cs2O, SrO, BaO and ZnO as a lining furnace material; producing a glass product by melting the glass material in the glass melting furnace and molding the melted glass material; determining a position of the glass defect source in the glass melting furnace by extracting the glass products having the glass defect and analyzing the component composition.
