  6. Cool Facts about Quartz • Roman naturalist Pliny the Elder believed quartz to be water ice, permanently frozen after great lengths of time. (The word "crystal" comes from the Greek word for purity.) He supported this idea by saying that quartz is found near glaciers in the Alps, but not on volcanic mountains, and that large quartz crystals were fashioned into spheres to cool the hands. He also knew of the ability of quartz to split light into a spectrum. This idea persisted until at least the 1600s.

  7. Uses of Quartz • Jewelry; watches • laboratory tubes and crucibles • radio, television, and radar • Quartz makes up almost all of two very important building stones. Sandstone is a rock made up of quartz sand held together by a natural cement. • Many more….
