There was no fundamental change in the technology of iron production in Europe for many centuries. European metal workers continued to produce iron in bloomeries. However, the Medieval period brought two developments—the use of water power in the bloomery process in various places (outlined above), and the first European production in cast iron.
Only the output of iron diminished less in relation to the other base and precious metals until the 8th century. This fact, correlated with the dramatic decrease in copper production, may indicate a possible displacement of copper and bronze artifacts by iron ones (Forbes 1957, 64; Bayley et al. 2008, 50).
Iron production continued to increase; the Weald in the South-East began to make increased use of water-power, and overtook the Forest of Dean in the 15th century as England's main iron-producing region. [27] The first blast furnace in England, a major technical step forward in metal smelting, was created in 1496 in Newbridge in the Weald. [28]

Iron treated this way is said to be wrought (worked), and the resulting iron, with reduced amounts of slag, is called wrought iron or bar iron. Because of the creation process, individual blooms can often have differing carbon contents between the original top and bottom surfaces, differences that will also be somewhat blended together through ...
The kappe was a Swedish weight used for osmond which occurs in a commercial treaty in Novgorod in 1203, and this implies the production of osmond iron. [3] Osmond iron was made by melting pig iron in a hearth that is narrower and deeper than a typical finery in an English finery forge. The hearth had a charcoal fire blown with bellows through a ...
Sustainable charcoal production for a post-medieval blast furnace required the timber production from a 3 miles (4.8 km) radius of a furnace in a landscape that was a quarter to a third wooded. Forging and finishing of the iron from bloomeries and blast furnaces also required large quantities of charcoal and was usually carried out at a ...
The earliest known activity on the site was a medieval mill race which supplied water to power the corn mill at Kirkstall Abbey. Iron production took place at the forge from the 1580s onwards. Kirkstall Abbey, a daughter abbey of Fountains was founded in 1152 by Abbot Alexander. [1] By the time of the Reformation the site covered 800 acres. [2]
