Abstract
Ancient glass chemical composition is diverse, and because of the environmental impact of weathering, the proportion of its composition will change, affecting the judgment of the glass category. Therefore, according to the relevant data, this paper queries a large number of literature, through reasonable statistical analysis to find the classification basis, and studies all kinds of glass relics before and after weathering, in order to play an important role in the composition analysis and identification of ancient glass products.To define the standard of correlation, so as to better explain the correlation degree of the respective chemical composition of the two types of glass; then, to compare the difference between the two types of glass in the above correlation relationship. The comparison model of individual differences was then established, and the gap between the two individual correlation coefficient was calculated from the absolute value distance, and compared with the defined evaluation criteria, which concluded that the glass of the two categories had significant individual differences in each pair of content of chemical composition. For example, both potassium oxide and calcium oxide are chemical components, with the absolute value distance of 1.319, and the difference level is very significant.
