The correlation between ZrO2 content and glass structure was investigated by performing principal component analysis on Raman and X-ray absorption fine structure (XAFS) spectra. 100 soda-lime glass samples with different ZrO2 contents were formed on a single substrate using a high-throughput micro glass melting system. Multivariate analysis of spectra obtained from multiple samples with continuously varying glass compositions revealed nonlinear changes in the network structure with the composition.
