Henry Cort (c. 1740 – 23 May 1800) was an English ironware producer who was formerly a Navy pay agent. During the Industrial Revolution in England, Cort began refining iron from pig iron to wrought iron (or bar iron) using innovative production systems.
In 1750, the UK imported 31,200 tons of bar iron and either refined from cast iron or directly produced 18,800 tons of bar iron using charcoal and 100 tons using coke. In 1796, the UK was making 125,000 tons of bar iron with coke and 6,400 tons with charcoal; imports were 38,000 tons and exports were 24,600 tons.
During the Industrial Revolution, new methods of producing bar iron by substituting coke for charcoal emerged, and these were later applied to produce steel, ushering in a new era of greatly increased use of iron and steel that some contemporaries described as a new "Iron Age".
The process of converting pig iron into wrought iron (also known as bar iron) was at that time carried out in a finery forge, which was fuelled by charcoal. Charcoal was a limited resource, but coal, more widely available, could not be used because the sulphur in coal would adversely affect the quality of the wrought iron. [1] Reverbatory furnace
An iron plantation in the Hopewell Furnace National Historic Site a living history museum in Elverson, Pennsylvania. Iron plantations were rural localities emergent in the late-18th century and predominant in the early-19th century that specialized in the production of pig iron and bar iron from crude iron ore. [1]
It was founded in 1857 by Lord Ward, who later became, in 1860, The 1st Earl of Dudley, as an outlet for pig iron made in the nearby blast furnaces. During the Industrial Revolution, the majority of iron-making in the world was carried out within 32 kilometres of Round Oak. For the first decades of operation, the works produced wrought iron.
The Barrow Hematite Steel Company Limited was a major iron and steel producer based in Barrow-in-Furness, Lancashire (now Cumbria), England, between 1859 and 1963. At the turn of the 20th century and the Technological Revolution it operated the largest steel mill in the world. [1]
