Glass weathering chemical composition prediction model

Abstract

This paper analyzes the relationship between glass surface weathering and glass type, decoration, and color, and predicts the chemical composition content of weathered glass before weathering. In this paper, firstly, the glass type and surface weathering were subjected to a chi-square test, and then the relationship between glass color, decoration and surface weathering was statistically analyzed using the control variable method: controlling for constant glass type. It is concluded that when the glass is high potassium glass, it tends to be non-weathered glass, while lead-barium glass tends to be weathered glass. High potassium glass with A ornamentation corresponds to all weathered glass, while B or C ornamentation corresponds to all unweathered glass, and the colors are dark blue, light blue, and dark green, corresponding to all weathered glass. The color of lead barium glass is black, blue-green, decorated with A; the color is light blue, decorated with C, all weathered glass. When the color is dark blue, the conclusion of the pattern is A. Then the average content changes of each chemical composition before and after the weathering of the two types of glass were counted separately, and the chemical composition content of the two types of weathered glass before weathering was calculated according to equation (3), respectively, and the specific results are shown in Table. 4.
