Copper is a chemical element with the symbol Cu (from Latin: cuprum) 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.

- Revelation 1:15 and his feet were like fine copper when glowing in a furnace; and his voice was as the sound of many waters.
- Copper deficiencies are thought to be linked to living in, and eating foods grown in, areas where the soil has been depleted of this mineral.
- Trace amounts of copper are essential for the human body. Since copper is not manufactured in the body it must be taken in through the diet. Copper is involved in the function of the nervous system. As with all toxic minerals, excess amounts of copper in the body can be toxic.
- Phyllis A. Balch in: "Prescription for Nutritional Healing", p. 340.
- He was only about as tall as Dorothy herself, and his body was round as a ball and made out of burnished copper. Also his head and limbs were copper, and these were jointed or hinged to his body in a peculiar way, with metal caps over the joints, like the armor worn by the knights in days of old. He stood perfectly still, and when the light struck upon his form it glittered as if made of pure gold.
- Chemical signs ought to be letters, for the greater facility of writing, and not to disfigure a printed book … I shall take therefore for the chemical sign, the initial letter of the Latin name of each elementary substance: but as several have the same initial letter, I shall distinguish them in the following manner:— 1. In the class which I shall call metalloids, I shall employ the initial letter only, even when this letter is common to the metalloid and to some metal. 2. In the class of metals, I shall distinguish those that have the same initials with another metal, or a metalloid, by writing the first two letters of the word. 3. If the first two letters be common to two metals, I shall, in that case, add to the initial letter the first consonant which they have not in common: for example, S = sulphur, Si = silicium, St = stibium (antimony), Sn = stannum (tin), C = carbonicum, Co = colbaltum (colbalt), Cu = cuprum (copper), O = oxygen, Os = osmium, &c

- Then I separated twelve of the chief of the priests, Sherebiah, Hashabiah, and ten of their brethren with them,
And weighed unto them the silver, and the gold, and the vessels, even the offering of the house of our God, which the king, and his counsellors, and his lords, and all Israel there present, had offered:
I even weighed unto their hand six hundred and fifty talents of silver, and silver vessels an hundred talents, and of gold an hundred talents;
Also twenty basons of gold, of a thousand drams; and two vessels of fine copper, precious as gold.
- Consider the eighth category, which deals with stones. Wilkins divides them into the following classifications: ordinary (flint, gravel, slate); intermediate (marble, amber, coral); precious (pearl, opal); transparent (amethyst, sapphire); and insoluble (coal, clay, and arsenic). The ninth category is almost as alarming as the eighth. It reveals that metals can be imperfect (vermilion, quicksilver); artificial (bronze, brass); recremental (filings, rust); and natural (gold, tin, copper)...

- Ayurveda recommends storing water in Copper Vessels. Ancient Egyptians used Copper Vessels to keep water fresh. Even today, management of Shiva temple at Rameswaram uses large sized Copper vessels to store water brought from river Ganges to offer to lord Shiva. Water, stored thus, stays fresh for years together. According to scientists, copper vessel can be the answer to kill the `E-Coli' bacteria which causes food poisoning. British scientists are carrying out research on copper and concluded that copper ions kill these harmful bacteria, a capability not found in any other metals including gold.

Sometimes you can go much farther by sitting in your own home and reading a book of history, than by getting onto a ship or an airplane and traveling a thousand miles. When you go to Mexico City through space, you find it a sort of cross between modern Madrid and modern Chicago, with additions of its own; but if you go to Mexico City through history, back only 500 years, you will find it as distant as though it were on another planet: inhabited by cultivated barbarians, sensitive and cruel, highly organized and still in the Copper Age, a collection of startling, of unbelievable contrasts.

- Shakudō (red copper) is Japanese copper which consists about 95% copper, 1 percent silver and 1-5 percent gold. Before a suitable treatment of its surface, it has a dark copper colour, but when completely pickled it acquires a rich black surface with a violet sheen. It can be treated to form an indigo/black patina resembling lacquer. Unpatinated shakudō visually resembles bronze; the dark color is induced by applying and heating rokushō, a special patination formula.

- In the last four days I have got the spectrum given by Tantalum, Chromium, Manganese, Iron, Nickel, Cobalt, and Copper and part of the Silver spectrum. The chief result is that all the elements give the same kind of spectrum, the result for any metal being quite easy to guess from the results for the others. This shows that the insides of all the atoms are very much alike, and from these results it will be possible to find out something of what the insides are made up of.

- While reading in a textbook of chemistry, … I came across the statement, 'nitric acid acts upon copper. I was getting tired of reading such absurd stuff and I determined to see what this meant. Copper was more or less familiar to me, for copper cents were then in use. I had seen a bottle marked 'nitric acid' on a table in the doctor's office where I was then 'doing time.' I did not know its peculiarities, but I was getting on and likely to learn. The spirit of adventure was upon me. Having nitric acid and copper, I had only to learn what the words 'act upon' meant... I put one of them [cent] on the w:Table:table, opened the bottle marked 'nitric acid'; poured some of the liquid on the copper; and prepared to make an observation. But what was this wonderful thing which I beheld? The cent was already changed, and it was no small change either. A greenish blue liquid foamed and fumed over the cent and over the table. The air in the neighborhood of the performance became colored dark red. A great colored cloud arose. This was disagreeable and suffocating—how should I stop this? I tried to get rid of the objectionable mess by picking it up and throwing it out of the window, which I had meanwhile opened. I learned another fact—nitric acid not only acts upon copper but it acts upon fingers. The pain led to another unpremeditated experiment. I drew my fingers across my trousers and another fact was discovered. Nitric acid acts upon trousers. Taking everything into consideration, that was the most impressive experiment, and, relatively, probably the most costly experiment I have ever performed.

- It is necessary to deprive matter of its qualities in order to draw out its soul. ...Copper is like a man; it has a soul and a body; ...the soul is the most subtile part, ...that is to say, the tinctorial spirit. The body is the ponderable, material, terrestrial thing, endowed with a shadow. ...After a series of suitable treatments copper becomes without shadow and better than gold. ...The elements ...grow and are transmuted, because it is their qualities, not their substances, which are contrary.

- As copper can be difficult to cast but easy to shape by hammering, it has been used since very early times to make items of beaten sheet metal...Copper [also] takes fire gilding better than its alloys, and many examples of the deliberate use of copper, rather than the more usual bronze or brass, for objects to be fire gilded are known. Copper has a pleasing and distinctive colour and has always been widely used for inlays into other metals, notably silver or the more golden bronze or brass.

- Copper had already been known for thousands of years by the time Otzi forged his axe. Archaeologists, found humankinds earliest use of element in the modern-day Turkey, Iran, and Iraq, the same spots that spawned civilization. A copper pendant found in northern Iraq dates to 8,700 years before Christ, plenty old enough to engender myth. The Greek island Cyprus took its name from Copper’s Latin cupras and the plentiful stores of green rocks that made it the go-to-source for the copper seeking civilizations of Greece, Rome, Phoenicia and Ionia in the three thousand years pre-dating Jesus. Venus was copper’s goddess, wearing an Egyptian ankh, emerging from the waves near her island protectorate to confirm her charms in a mirror made from the polished pink metal. The Greeks knew copper as an antiseptic and mixed glittery flakes with honey as a dressing for wounds.

- A person cannot live in a modern manner without copper. Electricity flipped the switch. While the pre-modern world’s use of copper depended on hardened alloys with other metals, the industrialized world’s dependence relies on alloyed copper, purged of impurities, to conduct electricity. Today an average American home is laced with 439 pounds of copper wiring and plumbing, with another hundred pounds embedded in household appliances like water heaters, air conditioners, and refrigerators. The average American car is strung with more than 600,000 feet of the stuff. In the United States alone, 130 million cellphones are retired very year, containing 2,100 metric tons of copper – enough to build twenty-six new copper-sheathed Statues of Liberty.

Metals And Mining: In the Bible
- Six metals are mentioned in the Bible and in many passages they are listed in the same order: gold, silver, copper, iron, tin, and lead... The Bible speaks of the high qualifications necessary for the specialized metalwork of the Tabernacle: "I have endowed him with a divine spirit of skill, ability, and knowledge...to make designs for work, in gold, silver, and copper... Solomon was forced to bring the craftsman Hiram from Tyre to work in copper.
- The copper referred to in the Bible is not pure copper but an alloy of copper and tin. This alloy – bronze – was the most useful and important metal from the beginning of the third millennium BC to the 13th century BC when it began to be replaced by iron. Copper mines in the ancient Near East were located in Cyprus (from which the name copper is apparently derived), Sinai, and Egypt. It was the main metal extracted in Ereẓ Israel in antiquity and is the only one mined there today. Copper is usually extracted from sulfide minerals, and partly from silicates, and carbonates; very small amounts of native copper are also found.
- Copper was even exported from the Arabah by Solomon, and also that the protracted wars between Judah and Edom during the period of the Kingdom of Judah were over control of the copper mines in the Arabah
- Much copper was used in manufacturing vessels for the Temple and especially for the Tabernacle: clasps, sockets, rings, posts of the enclosure, lavers, etc. The biblical description of copper weapons indicates a highly developed military culture, e.g., the description of Goliath: "He had a helmet of bronze on his head, and he was armed with a coat of mail, and the weight of the coat was 5,000 shekels of bronze”. Copper was fashioned into a symbol for the Israelites in the desert in the form of a serpent of copper made by Moses.
- In its use in vessels for the Tabernacle and Temple and for weapons, copper symbolized strength and rigidity – The skies above your head shall be copper. It also denoted drought – "I will make your skies like iron and your earth like copper". The word for chains (neḥushtayim) is also derived from copper. Not only the heaven and earth but also the Israelites are compared with rigid copper: "your forehead copper”.
