Faden quartz is a descriptive term for a usually tabular group of quartz crystals with a white thread-like or string-like zone running through the interior. The term faden is a German word for thread. They are found in the Alpine region of Europe, Pakistan, Russia and Arkansas.
Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO 2). It is the most abundant mineral found at Earth's surface and its unique properties make it one of the most useful natural substances.uartz is very resistant to both chemicals and heat. It is therefore often used as a foundry sand. With a melting temperature higher than most metals it can be used for the molds and cores of common foundry work. Refractory brick are often made of quartz sand because of its high heat resistance.
