| quartz | <chemical> A form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colourless and transparent, but sometimes also yellow, brown, purple, green, and of other colours; also in cryptocrystalline massive forms varying in colour and degree of transparency, being sometimes opaque. The crystalline varieties include: amethyst, violet; citrine and false topaz, pale yellow; rock crystal, transparent and colourless or nearly so; rose quartz, rosecoloured; smoky quartz, smoky brown. The chief crypto-crystalline varieties are: agate, a chalcedony in layers or clouded with different colours, including the onyx and sardonyx; carnelian and sard, red or flesh-coloured chalcedony; chalcedony, nearly white, and waxy in luster; chrysoprase, an apple-green chalcedony; flint, hornstone, basanite, or touchstone, brown to black in colour and compact in texture; heliotrope, green dotted with red; jasper, opaque, red yellow, or brown, coloured by iron or ferruginous clay; prase, translucent and dull leek-green. Quartz is an essential constituent of granite, and abounds in rocks of all ages. It forms the rocks quartzite (quartz rock) and sandstone, and makes most of the sand of the seashore. Origin: G. Quarz. Source: Websters Dictionary (01 Mar 1998) |

| quartz wedge | <microscopy> A compensator consisting of a gradual wedge of quartz of such orientation and dimensions as to show at least several orders of retardation colours as illustrated by the Michel Levy scale of retardation colours and birefringence vs. Thickness of specimen. The Babinet compensator employs two opposing quartz wedges, calibrated in terms of retardation. (05 Aug 1998) |

| quartz |
Quartz is the second most abundant mineral in the Earth's crust. It has a hexagonal crystal structure made of trigonal crystallized silica (silicon dioxide, SiO2), with a hardness of 7 on the Mohs scale. Density is 2.6 g/cm³. The typical shape is a six-sided prism that ends in six-sided pyramids, although these are often distorted, or so massive that only part of the shape is apparent from a mined specimen. ...
