Paragraph starter

The selection and application of glass in design are critically dependent on an understanding of its fundamental science. Processes such as glass formation, crystallization, and phase separation, influenced by composition and thermal history, directly dictate the material's physical, optical, electrical, chemical, and mechanical properties. Therefore, for effective design, it is essential to consider how these intrinsic behaviors can be leveraged or mitigated to achieve desired product performance and durability.
