Physical and chemical properties of silicon glass. Silicon glass has a low coefficient of thermal expansion. It means that it is resistant to thermal shock. When heated to very high temperatures (as high as 1100°C), it will not crack even if suddenly cooled in water. Other significant utility advantages of quartz glass are: perfect transparency;
