Chemical composition correlation between high potassium glass and lead-barium glass

Abstract

The Silk Road was a channel for cultural exchange between China and the West in ancient times, of which glass was a valuable physical evidence of early trade exchanges. Early glass was often made into bead-shaped ornaments in the West Asian and Egyptian regions into our country, and our ancient glass was made locally after absorbing its technology, so it was similar in appearance to foreign glass products, but the chemical composition was not the same. As glass is highly susceptible to weathering by the burial environment, during the weathering process, a large number of internal elements are exchanged with environmental elements, resulting in a change in its composition ratio, which affects the correct judgment of its category. According to the proportion of chemical composition of glass artifacts, it was split into high potassium glass data and lead-barium glass data, and the Pearson correlation coefficient was studied by using matlab software for high potassium glass data and lead-barium glass data respectively, so as to analyze the correlation between each chemical composition.
