Gold dust

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.] [1913 Webster] 1. (Chem.) A metallic element of atomic number 79, 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 (melting point 1064.4[deg] C), moisture, and most corrosive agents, and therefore well suited for its use in coin and jewelry. Symbol Au ({Aurum}). Atomic weight 196.97. [1913 Webster]

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. [1913 Webster]

2. Money; riches; wealth. [1913 Webster]

For me, the gold of France did not seduce. --Shak. [1913 Webster]

3. A yellow color, like that of the metal; as, a flower tipped with gold. [1913 Webster]

4. Figuratively, something precious or pure; as, hearts of gold. --Shak. [1913 Webster]
