quartz glass, quartz, vitreous silica, lechatelierite, crystal(noun)
colorless glass made of almost pure silica
a hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities
The most abundant mineral on the earth's surface, of chemical composition silicon dioxide, SiO. It occurs in a variety of forms, both crystalline and amorphous. Found in every environment.
Origin: Quarz, from twarc, probably from a West Slavic language (compare Czech tvrdý, Polish twardy, Russian твёрдый), from тврьдъ, from tvьrdъ.
a form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colorless and transparent, but sometimes also yellow, brown, purple, green, and of other colors; also in cryptocrystalline massive forms varying in color and degree of transparency, being sometimes opaque
Origin: [G. quarz.]
Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings. The word "quartz" is derived from the German word "Quarz" and its Middle High German ancestor "twarc", which probably originated in Slavic.

U.S. National Library of Medicine
Quartz (SiO2). A glassy or crystalline form of silicon dioxide. Many colored varieties are semiprecious stones. (From Grant & Hackh's Chemical Dictionary, 5th ed)
The Standard Electrical Dictionary
A mineral, silica, SiO2. It has recently been used by C. V. Boys and since by others in the making of filaments for torsion suspensions. The mineral is melted, while attached to an arrow or other projectile. It is touched to another piece of quartz or some substance to which it adheres and the arrow is fired off from the bow. A very fine filament of surpassingly good qualities for galvanometer suspension filaments is produced. As a dielectric it is remarkable in possessing but one-ninth the residual capacity of glass.
