Quartz vs. Fused Silica: What’s the Difference? - Swift Glass

Sep 08, 2015  Fused Silica is an entirely synthetic material, and is technically the purest glass. It has the highest temperature characteristics of any glass, and it often begins as pure silicon gas. Because of the way fused silica is made, it has superior ultraviolet performance to natural quartz and is ideal for applications such as UV transmitting optics.
