Samuel Johnson's Dictionary

  1. COPPERnoun

    One of the six primitive metals.

    Etymology: koper, Dut. cuprum, Latin.

    Copper is the most ductile and malleable metal, after gold and silver. Of a mixture of copper and lapis calaminaris is formed brass; a composition of copper and tin makes bell-metal; and copper and brass, melted in equal quantities, produces what the French call bronze, used for figures and statues. Ephraim Chambers.

    Copper is heavier than iron or tin; but lighter than silver, lead, and gold. It is not unfrequently found native in a malleable state, but in small quantities. In the state of ore it makes, according to its various admixtures, many very different appearances. The richer copper ores are found in many parts of Germany and Sweden; and we have some in England little inferior to the finest Swedish. John Hill, on Fossils.

    Two vessels of fine copper, precious as gold. Ezra, viii. 27.

  2. Coppernoun

    A vessel made of copper; commonly used for a boiler larger than a moveable pot.

    They boiled it in a copper to the half; then they poured it into earthen vessels. Francis Bacon, Natural History, №. 848.

Freebase

  1. Copper

    Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The metal and its alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium, later shortened to сuprum. Its compounds are commonly encountered as copper salts, which often impart blue or green colors to minerals such as azurite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris. Decorative art prominently features copper, both by itself and as part of pigments. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustacea copper is a constituent of the blood pigment hemocyanin, which is replaced by the iron-complexed hemoglobin in fish and other vertebrates. The main areas where copper is found in humans are liver, muscle and bone. Copper compounds are used as bacteriostatic substances, fungicides, and wood preservatives.
