A pencil, containing a solid pigment core within a protective casing, is a common writing implement or art medium. Having a case keeps the pigment from breaking as well as from marking the user's hand. Pencils differ from pens because they leave marks by physical abrasion rather than staining the paper. The pigment leaves behind a trail of material that adheres to the sheet of paper or other writing surface. Cores are usually made of graphite mixed with clay to bind it. Graphite is durable...

Graphite (named by Abraham Gottlob Werner in 1789, from the Greek γραφειν: "to draw/write", for its use in pencils) is one of the allotropes of carbon. Unlike diamond, graphite is a conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. Occurrence Associated minerals include: quartz, calcite, micas, iron meteorites and tourmalines. Notable occurrences include New York and Texas in the USA, Russia, Mexico, Greenland,...

postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
