The Quartz Page: Physical Properties

Silica glass (quartz glass a.k.a. fused quartz) has a thermal expansion coefficient about 1/18th of that of ordinary glass; a red hot silica glass rod can be dipped into water without cracking. Lenses made of silica glass and fixed in a rigid apparatus do not get distorted by changes in temperature.
