Mining, smelting, and casting of copper ore were preceded by elaborate ceremonies to ensure that the endeavors were safe and fruitful. Copper also plays a role today in many New Age beliefs. In some modern religions, it is seen as having healing powers, both spiritually and physically. Some people wear copper to help alleviate the symptoms of arthritis.
The people of the Indian subcontinent have been using copper and its alloys as long as anyone. Bronze casting was extensive in ancient times and bronze was used for religious statues and artwork. This practice also spread to Southeast Asia where copper and its alloys are used extensively even today in Buddhist artwork. Copper was first used in China around BC. The Chinese quickly began using bronze as well, and used different percentages of tin in bronze for different purposes.
They used copper and bronze extensively for coinage. During the flourishing economic activity and expanded foreign trade in the Sung dynasty, circa to AD, the use of cash—round copper coins with a square hole in the middle—exploded. Copper production was now reaching almost industrial proportions in some civilizations, though probably nowhere more than in ancient Rome. Although iron and lead were in use by the era of the ancient Romans, copper, bronze, and brass an alloy of copper and zinc were used by the Romans for coins, aspects of architecture such as doors, and some parts of their extensive plumbing system although pipes were made of lead.
They also developed pipe organs made with copper pipes. The Romans controlled extensive copper deposits throughout their empire. Scientists analyzing copper isotopes and trace metals present in Roman copper coins have determined that Rio Tinto, Spain still a working copper mine , Cyprus, and to a lesser extent Tuscany, Sicily, Britain, France, Germany and other parts of Europe and the Middle East were sources of copper for the Empire. Increased purity of Roman copper coins over time also shows that their smelting methods improved quickly.
The Romans in their heyday produced nearly 17, tons of copper annually, more than would be produced again until the Industrial Revolution in Europe. With this enormous output of copper came pollution that would be unsurpassed for almost two thousand years when the Industrial Revolution began.
Did polluted air from early copper smelting affect the health of humans living in ancient times? Early smelting methods at that time were crude and inefficient by the standards of today. Copper smelting and to a lesser degree copper mining produced ultra-fine particle dust that was carried into the atmosphere on air currents created by the intense heat from smelting operations. Most of the pollution would have fallen near the smelting sites, causing health problems and contaminating soil and water.
Scientists in the s discovered that copper contamination is present in 7,year-old layers of ice in the Greenland glacial caps. A layer of ice is deposited on glacial caps annually, allowing a year-by-year analysis of the ice composition. As copper smelting became widespread at the beginning of the Bronze Age, enough copper was released into the air to contaminate ice thousands of miles away.
Peaks in copper concentrations in ice layers correspond to the era of the Roman Empire, the height of the Sung dynasty in China c. The copper pollution of the Roman days still haunts us today. One former Roman copper mine and smelting site in Wadi Faynan, Jordan is still — two thousand years after it ceased operations — a toxic wasteland littered with slag from copper smelting.
Researchers have discovered that vegetation and livestock in Wadi Faynan today have high copper levels in their tissue. Beginning in the late s, copper smelting became a major industry in Great Britain. Copper ore from Cornwall and other areas and coal deposits throughout the country fueled the smelting of copper. The copper industry drove the economy of this town. This can be observed in the case of electric cars versus gasoline-powered cars, and more generally in the use of fossil fuels versus renewable energy sources.
It was true in the past that many ancient Egyptian treasures were accessible only in Egypt or in world museums. Complete documentation for excavating the famous tomb of Tutankhamun is also online at the Griffith Institute of the University of Oxford.
However, online and open-access resources about ancient Egyptian metallurgy are rather scarce, and there is also misleading information in popular works.

The Egyptians even possessed bronze model bags which were carried by servants at important funerals. Figure 3. Lead isotope analyses of a copper vessel found in a First Dynasty ca. This is the earliest evidence of Anatolian—Egyptian copper trade that can be accurately dated.
Ancient Egyptians may have desired the Anatolian metal because its combination of copper, arsenic and nickel gave it a unique [more whitish] colour, explains Egyptologist Martin Odler of Charles University in the Czech Republic. He expects the metal was part of the interregional trade in the late 4th and early 3rd millennia BCE.
