- Here is a copy of the historic timeline found on the American Foundry website.
I removed anything after 1776.
9000 B.C.-Earliest metal objects of wrought native copper are produced in the Near East.
3000-2500 B.C.-Small objects are cast via lost wax (investment casting) process in the Near East.
3200 B.C.-The oldest casting in existence, a copper frog, is cast in Mesopotamia.
3000 B.C.-Early foundrymen cast bronze tools and weapons in permanent stone molds.
1500 B.C.-Wrought iron is discovered in the Near East.
600 B.C.-The first cast iron object, a 600-lb tripod, is cast by the Chinese.
233 B.C-Iron plowshares are cast.
200 B.C.-Oldest iron castings still in existence are produced during the Han Dynasty.
500-Cast crucible steel is produced in India.
1200s-Loam or sweep molding is used by European foundrymen to cast bells for cathedrals.
1252-The colossal statute, the Great Buddha at Kamakura, Japan, is cast in high-lead tin bronze. The project began in the
700s and its head alone weighed 140 tons.
1313-The first cannon is cast in bronze by a monk in the city of Ghent.
1400s-During the siege of Constantinople, heavy guns are cast from bronze "on the spot," virtually under the walls of the besieged city Movable, cast lead type for printing presses revolutionizes the world's methods of communication.
1480-Vannoccio Biringuccio (1480-1539), the first true foundryman and the "father of the foundry industry," is born. The founder of the Vatican, his De La Pirotechnia is the first written account of proper foundry practice.
1500s-Sand is introduced as a molding material in France.
1612-Mined from under the sea, seacoal is mentioned for the first time by German foundryman and inventor, Simon Sturtevant.
1619-North America's first iron furnace is built at Falling Creek, VA, a branch of the James River, 60 miles from Jamestown colony. Three years later, Native Americans destroy it during a raid.
1645-Earliest recorded use of term "foundry" appears in the Oxford English Dictionary in its variant "founderie."
1646-America's first iron foundry (and second industrial plant), Saugus Iron Works, near Boston, pours the first American casting, the Saugus pot. The Saugus River site was selected by Richard Leader and was built to produce iron products for Massachusetts and England.
1661-First U.S. copper deposits are discovered by Gov. Winthrop in Middletown, CT.
1709-Two developments by Abraham Darby, Coalbrookdale, England, improve casting methods. He developed the first true foundry flask to modernize molding practices (which had been carried out in pits on the floor by use of pattern boards tied together or in crude box frames). He would later initiate the use of coke as a furnace fuel for iron production.
1722-A.F. de Reamur, recognized as the world's first metallurgical chemist, develops first malleable iron, known today as European Whiteheart malleable.
1750-Benjamin Huntsman reinvents the cast crucible steel process in England, a process that disappeared after first being developed in India The English parliament prohibits the refining of pig iron or the casting of iron in the American colonies, contributing to the American Revolution.
1756-Coalbrookdale's Richard Reynolds oversees the invention of cast iron tram-road rails, replacing wooden rails.
1775-Revolutionary patriot < a href="http://en.wikipedia.org/wiki/Paul_Revere" target="_new">Paul Revere, who operated a belland-fittings foundry in Boston, rides from Boston to Lexington warning colonists of the British invasion.
1776-Foundrymen Charles Carroll, James Smith, George Taylor, James Wilson, George Ross, Philip Livingston and Stephen Hopkins sign the American Declaration of Independence.
