                                      In engineering, optics, and high-temperature industrial systems, the selection between quartz glass and regular (soda-lime) glass directly influences system stability, performance, and lifetime. Although both are transparent materials based on silica, their structure, composition, and behavior under stress are fundamentally different. This guide provides a practical engineering comparison for designers, procurement engineers, and industrial users.
