Copper definitions

Webster's 1828 Dictionary

COPPER, n. [L., G., supposed to be so called from Cyprus, an isle in the Mediterranean. This opinion is probable, as the Greeks called it Cyprian brass, brass of Cyprus. In this case copper was originally an adjective.] A metal, of a pale red color, tinged with yellow. Next to gold, silver and platina, it is the most ductile and malleable of the metals, and it is more elastic than any metal, except steel, and the most sonorous of all the metals. It is found native in lamins or fibers, in a gangue almost always quartzous; it is also found crystalized, and in grains or superficial lamins on stones or iron. It is not altered by water, but is tarnished by exposure to the air, and is at last covered with a green carbonated oxyd. Copper in sheets is much used for covering the bottoms of ships, for boilers and other utensils; mixed with tin and zink, it is used in enamel-painting, dyeing, etc. : mixed with tin, it forms bell-metal; with a smaller proportion, bronze; and with zink, it forms brass, pinchbeck, etc. When taken into the body ti operates as a violent emetic, and all its preparations are violent poisons.
COPPER, a. Consisting of copper.
COPPER,n.
1. A vessel made of copper, particularly a large boiler.
2 Formerly, a small copper coin.
My friend filled my pocket with coppers.
COPPER, v.t. To cover or sheathe with sheets of copper; as, to copper a ship.

Britannica Concise

Metallic chemical element, one of the transition elements, chemical symbol Cu, atomic number 29. Sometimes found in the free state in nature, it is a reddish metal, very ductile and an unusually good conductor of electricity and heat. Most copper is used by the electrical industries; the remainder is combined with other metals, incl. brass, bronze, nickel, and silver, to form alloys. Copper is part of nearly all coinage metals. In compounds copper usually has valence 1 (cuprous) or 2 (cupric). Cuprous compounds include cuprous oxide, a red pigment and a fungicide; cuprous chloride, a catalyst for certain organic reactions; and cuprous sulfide, with a variety of uses. Cupric compounds include cupric oxide, a pigment, decolorizing agent, and catalyst; cupric chloride, a catalyst, wood preservative, mordant, disinfectant, feed additive, and pigment; and cupric sulfate, a pesticide, germicide, feed additive, and soil additive. Copper is a necessary trace element in the diet and essential to plant growth; in blue-blooded mollusks and crustaceans it plays the same role in hemocyanin as iron does in hemoglobin. Any member of the butterfly subfamily Lycaeninae (family Lycaenidae). Coppers are common and widely distributed. Adults, sometimes known as gossamer-winged butterflies, are delicate, with a wingspan of 0.75-1.5 in. (18-38 mm). They are rapid fliers, usually with iridescent wings. Coppers typically range from orange-red to brown, usually with a copper tinge and dark markings. Copper larvae feed on clover, dock, or sorrel.

Easton's Bible Dictionary

derived from the Greek kupros (the island of Cyprus), called "Cyprian brass," occurs only in the Authorized Version in Ezra 8:27. Elsewhere the Hebrew word (nehosheth) is improperly rendered "brass," and sometimes "steel" (2 Sam. 22:35; Jer. 15:12). The "bow of steel" (Job 20:24; Ps. 18:34) should have been "bow of copper" (or "brass," as in the R.V.). The vessels of "fine copper" of Ezra 8:27 were probably similar to those of "bright brass" mentioned in 1 Kings 7:45; Dan. 10:6.

Tubal-cain was the first artificer in brass and iron (Gen. 4:22). Hiram was noted as a worker in brass (1 Kings 7:14). Copper abounded in Palestine (Deut. 8:9; Isa. 60:17; 1 Chr. 22:3, 14). All sorts of vessels in the tabernacle and the temple were made of it (Lev. 6:28; Num. 16:39; 2 Chr. 4:16; Ezra 8:27); also weapons of war (1 Sam. 17:5, 6, 38; 2 Sam. 21:16). Iron is mentioned only four times (Gen. 4:22; Lev. 26:19; Num. 31:22; 35:16) in the first four books of Moses, while copper (rendered "brass") is mentioned forty times. (See BRASS.)

We find mention of Alexander (q.v.), a "coppersmith" of Ephesus (2 Tim. 4:14).

International Standard Bible Encyclopedia

kop'-er (nechosheth): The word is translated "copper" in only one passage (Ezr 8:27 the King James Version). In the American Standard Revised Version of this passage, "brass" has been substituted. Neither describes the actual alloy according to present definitions so well as the word "bronze." Copper was one of the earliest metals to be known and utilized in alloy, but copper, as a single metal, was probably little used. The remains of spears, balances, arms, vases, mirrors, statues, cooking utensils, implements of all kinds, etc., from Bible times are principally of an alloy of copper hardened with tin known today as bronze (see BRASS). In such passages as De 8:9, where reference is made to the native metal or ores, "copper" should be substituted for "brass" as in the American Standard Revised Version (compare Job 40:18). This is true also of coins as chalkos, in Mt 10:9.

Our modern English word "copper" is derived from an old name pertaining to the island of Cyprus. Copper was known to the ancients as Cyprian brass, probably because that island was one of the chief sources for this metal. The Sinai peninsula and the mountains of northern Syria also contributed to the ancient world's supply (see Tell el-Amarna Letters). No evidences of copper ore in any quantity are found in Palestine proper.

See METAL; MINE.

James A. Patch.

COPPERSmith

kop'-er-smith (chalkeus): The word is found in New Testament once only, in 2Ti 4:14: "Alexander the coppersmith did (margin "showed") me much evil." As the Bible word rendered "copper" (see Ezr 8:27 the King James Version) is translated "brass" by the Revised Version (British and American), so the word here rendered "c." should be rendered "brazier," or "worker in brass."

See COPPER.
