bar iron
method, process, technology
Wrought or rolled iron in the form of a bar.
Johann Conrad Fischer distinguished between conventional wrought or bar iron and smelted, pure bar iron (‘Fischer’s bar iron’), which was more difficult to produce. He was proud of his ability to smelt in his furnaces and crucibles “pure bar iron without any admixture […] while preserving its ductility and its property of not toughening as a result of annealing and quenching in water.” (Journal 1825–1827, p. 43). The transfer of this knowledge seems to have been the purpose of the partnership with John Martineau. His son Johann Conrad Fischer the Younger is thought to have produced pure bar iron for Martineau in the 1820s.
It is sometimes, though rarely, referred to as profile iron.
