Quartz glass is a one-component glass (SiO2). It is one of the most valuable materials for both science and industry. There is a distinction between synthetic and natural quartz glass. Synthetic quartz glass is made from pure silicon tetrachloride (SiCl4) following the Flammpyrolyse-method. The raw material of quartz glass is a natural crystal mined from the earth as rock crystal or pegmatite quartz. The raw material is pulverized to a fine-particle granulate and melted to quartz glass in an oxy-hydrogen flame.
