cal symbol, Cu; atomic weight, 63.3. A metal 
distinguished from all others by its peculiar red 
color. Its crystalline form is that of the cube or regular 
octahedron (isometric). Its specific gravity is nearly nine 
times that of water (8.838 native copper, 8.958 electrotype 
copper). Among the metals in common use, it stands next 
to gold and silver in malleability and ductility, and next 
to iron and steel in tenacity. Its melting-point is a little 
below that of gold and considerably above that of silver. 
Copper is one of the most widely diffused metals, and 
occurs in the native state, as well as in a great variety of 
sulphureted and oxidized combinations. Native copper 
is not unfrequently met with in the superficial portions 
of cupriferous lodes, but usually only in small amount. 
In two regions, however, this metal is mined exclusively in 
the native state : namely, the south shore of Lake Superior, 
and Corocoro in Bolivia ; but of the two the former is by 
far the more important, and produces about one sixth 
of the total yield of the world. In the Lake Superior re- 
gion the copper occurs in regular flssure-veins, and also 
in a conglomerate of volcanic origin, forming the cement by 
which tlie pebbles are held together. In the fissure-veins 
large masses of native copper have frequently been found, 
one such mass weighing over three hundred tons. Most 
of the copper of the world, previous to the opening of this 
region, was produced from ores consisting of combinations 
of the metal with certain mineralizers, such as sulphur 
and oxygen, and especially sulphur. The most abundant 
ore is the so-called " yellow copper ore " or copper pyrites, 
the chalcopyrite of the mineralogist, which is composed 
of copper, iron, and sulphur, and contains, when chemi- 
cally pure, 34.6 per cent, of copper. The total copper-pro- 
duction of the world for the year 1886 may be estimated at 
215,000 tons, of which the United States produced about 
one third ; it had increased rapidly within the preceding 
twenty-five years. The copper of the United States comes 
chiefly from Lake Superior, Arizona, and Montana. Spain, 
Chili, Prussia, and Australia are other large producers of 
this metal. Copper has been known from the remotest ages, 
and was mined extensively on Lake Superior before the 
advent of Europeans. Its uses are manifold. The most 
important of them was, before the very general use of iron 
in ship-building, as a sheathing metal, first by itself, and 
later as a part of the alloy called yedou' metal, a variety 
of brass. On account of its electric conductivity, copper 
is largely used for induction-coils and all kinds of electri- 
cal apparatus, and for the cores of telegraph-cables. For 
these uses very pure copper is required ; a slight admix- 
ture of iron greatly increases its electrical resistance. For 
domestic purposes copper is made up in a great variety of 
forms, either by itself, or tinned in order to prevent corro- 
sion by acid liquids. The electrotyping process depends 
on the deposition by the galvanic current of pure copper 
from a solution of one of its salts, the metal deposited 
, 
forming an exact reproduction in copper of an object sus- 
pended for that purpose in the bath. The alloys of copper 
are of great importance, and one of them, bronze, is of high 
, , , 
antiquity. The salts of copper are also numerous, and are 
invaluable in the arts. Copper sulphate, or blue vitriol, 
is largely used in calico-printing, in electro-metallurgy, 
and in the preparation of the copper pigments Scbeele'a 
green, Schweinfurt green, find Puris green, the latter be- 
ing much used as an insecticide, principally for the Colo- 
rado potato-beetle. See brass, bronze, and yellow metal 
(under metal). 
2. A vessel made of copper, particularly a large 
boiler ; specifically, in the plural, the large ket- 
tles or boilers in a ship's galley for boiling food 
for the ship's company. These lx lilers were formerly 
of copper, but are now usually of iron. The boilers used 
in various manufacturing operations, though frequently 
of other metals, still often retain the name copper.
