In this pap, that discriminant function is established for the coarse classification of the known glass, and the sub-classification result of the high-potassium glass is as follows: the K2O-Na2O-SiO2 glass, the K2O-CaO-SiO2 glass, the K2O-CuO-SiO2 glass, the sub-classification result of lead-barium glass are PbO-BaO-Na2O-SiO2 glass, the PbO-BaO-Al2O3-SiO2 glass, the PbO-BaO-SrO-SiO2 glass, the PbO-BaO-CaO-SiO2 glass, The subtaxonomic results correspond to the color and ornamentation, which indicates the rationality of subtaxonomic results. Sensitivity analysis showed that the sensitivity was small and the model was robust. It provides a reference for the subsequent study of the weathering and composition of ancient silicate glass.
