In this paper, the surface weathering, type, decoration, color and content of each chemical component of glass artifacts were studied and analyzed, and a K-means clustering model was established, using Spearman correlation analysis, chi-square test, and. It was solved to classify the glass types and analyze the change pattern of chemical composition of glass artifacts, and a better fitting effect was obtained. This paper characterized the problem as a prediction class, firstly, assigned values to four categorical variables: surface weathering, type, decoration and color of glass artifacts, and then used spss to perform Spearman correlation and chi-square test analysis to pre-process the data and eliminate invalid data. Then, it used descriptive statistical analysis to find that most of the chemical components of high potassium glass showed a decreasing trend after weathering, and most of the chemical components of lead-barium glass showed an increasing trend after weathering; finally, used Matlab matrix to derive a linear mapping relationship based on the changes of chemical components before and after weathering, and finally predicted the chemical components of glass artifacts before weathering.
