Classification and analysis of glass artifacts based on feature filtering

Abstract

Glass is an important physical evidence of the early trade between China and the West. In the early days, the glass introduced into China was mainly pearl shaped ornaments from Western Asia and Egypt. Later, China learned its glass manufacturing technology and used local materials to make glass. Therefore, although the appearance of local glass products is similar to that of foreign glass products, their chemical compositions are not the same. According to the data, the classification rules of high potassium glass and lead barium glass are analyzed; For each category, this paper choose appropriate chemical components to classify them into subclasses, give specific classification methods and results, and analyze the rationality and sensitivity of the classification results.
