Quartz Crystal SiO2
Description
Quartz is mined naturally, but more commonly produced synthetically in large, longfaceted crystals. Quartz is positive birefringent. Be careful not to confuse terminology in this material, as "Fused Quartz" is often used to denote the glassy non-crystalline form better known as Silica. Normal Quartz is Alpha Quartz and normally RH rotating. LH rotating is available on special order. At temperatures >490°C, Crystal Quartz starts to revert to glassy state, a process which is complete by 530°C.
