Document 3: Copper: Britain's first use of brass occurred around the 3rd–2nd century BC. In North America, copper mining began with marginal workings by Native Americans. Native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600. Copper metallurgy was flourishing in South America, particularly in Peru around 1000 AD; it proceeded at a much slower rate on other continents. Copper burial ornamentals from the 15th century have been uncovered, but the metal's commercial production did not start until the early 20th century.
Document 4: Alloy: Many ancient civilizations alloyed metals for purely aesthetic purposes. In ancient Egypt and Mycenae, gold was often alloyed with copper to produce red-gold, or iron to produce a bright burgundy-gold. Gold was often found alloyed with silver or other metals to produce various types of colored gold. These metals were also used to strengthen each other, for more practical purposes. Copper was often added to silver to make sterling silver, increasing its strength for use in dishes, silverware, and other practical items. Quite often, precious metals were alloyed with less valuable substances as a means to deceive buyers. Around 250 BC, Archimedes was commissioned by the king to find a way to check the purity of the gold in a crown, leading to the famous bath-house shouting of "Eureka!" upon the discovery of Archimedes' principle.
Document 5: Copper: The gates of the Temple of Jerusalem used Corinthian bronze made by depletion gilding. It was most prevalent in Alexandria, where alchemy is thought to have begun. In ancient India, copper was used in the holistic medical science Ayurveda for surgical instruments and other medical equipment. Ancient Egyptians (~2400 BC) used copper for sterilizing wounds and drinking water, and later on for headaches, burns, and itching. The Baghdad Battery, with copper cylinders soldered to lead, dates back to 248 BC to AD 226 and resembles a galvanic cell, leading people to believe this was the first battery; the claim has not been verified.
Document 6: Christopher Columbus (Vittori): Christopher Columbus is a public artwork by Italian artist Enrico Vittori and located on the grounds of the Indiana Statehouse in Indianapolis, Indiana. The sculpted bronze bust of Christopher Columbus sits atop a pedestal that has relief carvings on its front, left and right sides. The sculpture is installed in the southwest corner of the Indiana Statehouse lawn and was presented in 1920 as a gift from Italian immigrant communities in Indiana.
Document 7: Alloy: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.
Document 8: Columbus Doors: Columbus Doors (1855–1861), also known as the Rogers Doors, are a pair of massive bronze doors modeled by sculptor Randolph Rogers for the East Front of the United States Capitol in Washington, DC. They open into the Rotunda, and depict events from the life of Christopher Columbus.
Document 9: Columbus Fountain: Columbus Fountain also known as the Columbus Memorial is a public artwork by American sculptor Lorado Taft, located at Union Station in Washington, D.C., United States. A centerpiece of Columbus Circle, "Columbus Fountain" serves as a tribute to the explorer Christopher Columbus. The unveiling in 1912 was celebrated all over Washington, DC over the course of three days with parades, concerts and fireworks gathering tens of thousands of people from all over the world.
Document 10: King at Rest: King at Rest is a public artwork by American artist Lorenzo Ghiglieri (born 1931). It is located near the northwest entrance to the Indiana Convention Center, which is in downtown Indianapolis, Indiana, and is owned by the Indiana Convention Center & Lucas Oil Stadium. The realistic bronze sculpture of a lounging lion was purchased in 2001 by the Center.
Document 11: Alloy: Mercury has been smelted from cinnabar for thousands of years. Mercury dissolves many metals, such as gold, silver, and tin, to form amalgams (an alloy in a soft paste, or liquid form at ambient temperature). Amalgams have been used since 200 BC in China for plating objects with precious metals, called gilding, such as armor and mirrors. The ancient Romans often used mercury-tin amalgams for gilding their armor. The amalgam was applied as a paste and then heated until the mercury vaporized, leaving the gold, silver, or tin behind. Mercury was often used in mining, to extract precious metals like gold and silver from their ores.
Document 12: Copper: Copper compounds in liquid form are used as a wood preservative, particularly in treating original portion of structures during restoration of damage due to dry rot. Together with zinc, copper wires may be placed over non-conductive roofing materials to discourage the growth of moss.[citation needed] Textile fibers use copper to create antimicrobial protective fabrics, as do ceramic glazes, stained glass and musical instruments. Electroplating commonly uses copper as a base for other metals such as nickel.
Document 13: Benjamin Harrison (bust): Benjamin Harrison is a bust by American artist Richard Peglow, located in the north atrium on the second floor of the Indiana Statehouse, which is in Indianapolis, Indiana, United States. The bust is cast in bronze and depicts President Benjamin Harrison. The bust is placed in front of a grey and black marble shield with six stars tracing around the edge of the shape. The bust and shield are approximately wide by high and has a depth of . The artwork was cast and placed in the statehouse in 2008 in accordance with Indiana code Section 2. IC 4-20.5-6-12.
Document 14: Copper: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.
Document 15: Copper: The uses of copper in art were not limited to currency: it was used by Renaissance sculptors, in photographic technology known as the daguerreotype, and the Statue of Liberty. Copper plating and copper sheathing for ships' hulls was widespread; the ships of Christopher Columbus were among the earliest to have this feature. The Norddeutsche Affinerie in Hamburg was the first modern electroplating plant starting its production in 1876. The German scientist Gottfried Osann invented powder metallurgy in 1830 while determining the metal's atomic mass; around then it was discovered that the amount and type of alloying element (e.g., tin) to copper would affect bell tones. Flash smelting was developed by Outokumpu in Finland and first applied at Harjavalta in 1949; the energy-efficient process accounts for 50% of the world's primary copper production.
