   Note: The term was originally applied to the mineral pyrite,
         or iron pyrites, in allusion to its giving sparks when
         struck with steel.

   {Arsenical pyrites}, arsenopyrite.

   {Auriferous pyrites}. See under {Auriferous}.

   {Capillary pyrites}, millerite.

   {Common pyrites}, isometric iron disulphide; pyrite.

   {Hair pyrites}, millerite.

   {Iron pyrites}. See {Pyrite}.

   {Magnetic pyrites}, pyrrhotite.

   {Tin pyrites}, stannite.

   {White iron pyrites}, orthorhombic iron disulphide;
      marcasite. This includes cockscomb pyrites (a variety of
      marcasite, named in allusion to its form), spear pyrites,
      etc.

   {Yellow}, or {Copper}, {pyrites}, the sulphide of copper and

Copper \Cop"per\, n. [OE. coper (cf. D. koper, Sw. koppar, Dan.
   kobber, G. kupfer), LL. cuper, fr. L. cuprum for earlier
   Cyprium, Cyprium aes, i.e., Cyprian brass, fr. Gr. ? of
   Cyprus (Gr. ?), anciently renowned for its copper mines. Cf.
   {Cypreous}.]
   1. A common metal of a reddish color, both ductile and
      malleable, and very tenacious. It is one of the best
      conductors of heat and electricity. Symbol Cu. Atomic
      weight 63.3. It is one of the most useful metals in
      itself, and also in its alloys, brass and bronze.

   Note: Copper is the only metal which occurs native abundantly
         in large masses; it is found also in various ores, of
         which the most important are chalcopyrite, chalcocite,
         cuprite, and malachite. Copper mixed with tin forms
         bell metal; with a smaller proportion, bronze; and with
         zinc, it forms brass, pinchbeck, and other alloys.

   2. A coin made of copper; a penny, cent, or other minor coin
      of copper. [Colloq.]

            My friends filled my pockets with coppers.
                                                  --Franklin.

   3. A vessel, especially a large boiler, made of copper.

   4. pl. Specifically (Naut.), the boilers in the galley for
      cooking; as, a ship's coppers.

   Note: Copper is often used adjectively, commonly in the sense
         of made or consisting of copper, or resembling copper;
         as, a copper boiler, tube, etc.

               All in a hot and copper sky.       --Coleridge.

   Note: It is sometimes written in combination; as,
         copperplate, coppersmith, copper-colored.

   {Copper finch}. (Zo["o]l.) See {Chaffinch}.

   {Copper glance}, or {Vitreous copper}. (Min.) See
      {Chalcocite}.

   {Indigo copper}. (Min.) See {Covelline}.

Copper \Cop"per\, v. t. [imp. & p. p. {Coppered}; p. pr. & vb.
