Quartz glass is produced by compressing and heating quartz. Fused silica glass is produced by heating quartz until its melting point before cooling it rapidly. In the end, quartz glass has a higher density and greater compressive strength and fused silica is more translucent and homogeneous.

Because quartz glass is created by melting and heating quartz, it is extremely good chemical and thermal stability. However fused silica glass exhibits more uniform physical properties due to the fact that it is created by melting quartz, then cooling it rapidly. Quartz glass fused has better thermal shock resistance as well as better corrosion resistance.

Due to the superior chemical and thermal stability that quartz glass has, it’s frequently used in high-temperature and high-pressure chemically corrosive environments like optical instruments, chemical laboratories and semiconductor manufacturing. However due to the fact that fused quartz glass is more transparent and has better transparency and has a better resistance to corrosion typically, it is employed to light up glassware, lighting and decorative purposes.

In the end, while the quartz glass as well as fused glass are made from quartz, they are made with different ways of making them and different physical characteristics. Based on the different requirements for each application choosing the proper material can enhance the performance and durability for the products.
