Gold \Gold\ (g[=o]ld), n. [AS. gold; akin to D. goud, OS. & G.
   gold, Icel. gull, Sw. & Dan. guld, Goth. gul[thorn], Russ. &
   OSlav. zlato; prob. akin to E. yellow. [root]49, 234. See
   {Yellow}, and cf. {Gild}, v. t.]
   1. (Chem.) A metallic element, constituting the most precious
      metal used as a common commercial medium of exchange. It
      has a characteristic yellow color, is one of the heaviest
      substances known (specific gravity 19.32), is soft, and
      very malleable and ductile. It is quite unalterable by
      heat, moisture, and most corrosive agents, and therefore
      well suited for its use in coin and jewelry. Symbol Au
      (Aurum). Atomic weight 196.7.

   Note: Native gold contains usually eight to ten per cent of
         silver, but often much more. As the amount of silver
         increases, the color becomes whiter and the specific
         gravity lower. Gold is very widely disseminated, as in
         the sands of many rivers, but in very small quantity.
         It usually occurs in quartz veins (gold quartz), in
         slate and metamorphic rocks, or in sand and alluvial
         soil, resulting from the disintegration of such rocks.
         It also occurs associated with other metallic
         substances, as in auriferous pyrites, and is combined
         with tellurium in the minerals petzite, calaverite,
         sylvanite, etc. Pure gold is too soft for ordinary use,
         and is hardened by alloying with silver and copper, the
         latter giving a characteristic reddish tinge. [See
         {Carat}.] Gold also finds use in gold foil, in the
         pigment purple of Cassius, and in the chloride, which
         is used as a toning agent in photography.

   2. Money; riches; wealth.

            For me, the gold of France did not seduce. --Shak.

   3. A yellow color, like that of the metal; as, a flower
      tipped with gold.

   4. Figuratively, something precious or pure; as, hearts of
      gold. --Shak.
