Ancient glass preserved in a burial environment for a long time will weather, which in turn leads to changes in its chemical composition and proportion. In this paper, we analyzed the relationship between surface weathering and glass type, ornamentation and color, and used the statistical principles related to statistics to draw statistical graphs to find out the statistical pattern of the presence or absence of chemical composition content on the surface of the artifact samples; established a regression prediction model and used MATLAB software to calculate and predict the chemical composition content of this batch of ancient glass before weathering; solved the problem of dividing the subclasses of two glass types, high potassium glass, and lead-barium glass, and used K-mean clustering method and spectral clustering method for cluster analysis, determined the chemical composition indexes for the division, and the approximate range of values for the division, derived specific division methods and results, and finally analyzed the reasonableness and sensitivity of the results.
