   What is the difference between borosilicate glass and quartz?

Question 

What is the difference between borosilicate glass and quartz?

Answer 

There are many differences between borosilicate glass and quartz, either pure- or synthetic-fused silica types. The main differences are the percentage of compounds and the percentage of silica or SiO2 in the glass. Borosilicate is usually in the 80% range, while quartz is over 99%. Quartz is also capable of handling much higher temperatures up to 1,100° C. Quartz is typically used for high temperature applications, or where optical quality or dielectric properties are critical. Impurities in borosilicate glass are measured in percent; impurities in quartz are measured in PPM.
