White Bronze
White bronze is a white-coloured alloy. Examples of various alloys composed of copper, tin and zinc or composed of zinc, copper, aluminum and magnesium.Christopher H. Bierbaum''Alloy.''US-Patent NoUS778398./ref> A modern composition contains 55% copper, 30% tin and 15% zinc. A 1904 patent for "white bronze" is composed of 86% zinc, 9.9% copper, 4% aluminum and 0.1% magnesium. History Use in monuments In the United States, starting in the 1870s, white bronze was a material used in monuments, particularly gravestones. White bronze gravestones are most common in East Coast cemeteries, but can be found throughout the country. White bronze was also commonly used in Civil War memorials. White bronze monuments could be mass produced, providing a more affordable alternative to more traditional materials like bronze, marble, and granite. Northern manufacturers, like the Monumental Bronze Company in Bridgeport, Connecticut, and the National Fine Art Foundry in New York City, often produced ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

United States Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davi ...

Monumental Bronze Company
The Monumental Bronze Company of Bridgeport, Connecticut was a monumental mason firm specializing in the production of white bronze (zinc) monumental masonry, active between 1875 and 1912 with subsidiaries throughout the United States (Des Moines, Iowa, Detroit, Michigan, Chicago, Illinois), and Canada. There were a number of American companies in the 1880s that through their catalogs sold zinc ornaments nationwide, such as “urns, eagles, civic ornaments, architectural details, and even cigar store Indians.” Mullins of Salem, Ohio was the most prominent but only Monumental Bronze purveyed it in grave markers. A popular white bronze model was the "Infantryman" that was used in the 1880s by many American towns, to commemorate those who served in the Civil War. In the late 1800s, the company sold two versions of a Civil War soldier memorial, with nearly identical designs. The Union model had "U.S." (United States) on the belt buckle, while the Confederate model had "C.S." (Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridgeport, Connecticut
Bridgeport is the most populous city and a major port in the U.S. state of Connecticut. With a population of 148,654 in 2020, it is also the fifth-most populous in New England. Located in eastern Fairfield County at the mouth of the Pequonnock River on Long Island Sound, it is from Manhattan and from The Bronx. It is bordered by the towns of Trumbull to the north, Fairfield to the west, and Stratford to the east. Bridgeport and other towns in Fairfield County make up the Bridgeport-Stamford-Norwalk-Danbury metropolitan statistical area, the second largest metropolitan area in Connecticut. The Bridgeport-Stamford-Norwalk-Danbury metropolis forms part of the New York metropolitan area. Inhabited by the Pauguseett Native American tribe until English settlement in the 1600s, Bridgeport was incorporated in 1821 as a town, and as a city in 1836. Showman P. T. Barnum was a resident of the city and served as the town's mayor (1871). Barnum built four houses in Bridgepor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Alloys
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term ''copper alloy'' tends to be substituted, especially by museums. Composition The similarity in external appearance of the various alloys, along with the different combinations of elements used when making each alloy, can lead to confusion when categorizing the different compositions. There are as many as 400 different copper and copper alloy compositions loosely grouped into the categories: copper, high copper alloy, brasses, bronzes, copper nickels, copper–nickel–zinc (nickel silver), leaded copper, and special alloys. The following table lists the principal alloying element for four of the more common types used in mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
