University of Minnesota's Mineral Pages: Quartz

Since it is composed of quartz, the shells are harder than the apatite and calcite minerals that make up our teeth. When you polish your teeth, you actually are grinding the surface down with a very fine abrasive, often the shells of long dead plankton. One of the more interesting properties of some pure quartz crystals is that.
