    Pieces of cast iron were placed on afinery hearth, on whichcharcoal was being burned with a plentiful supply of air,so that carbon in the iron was removed by oxidation, leaving semisolid malleable iron behind. From the 15th century on, this two-stage process gradually replaced direct iron making, which nevertheless survived into the 19th century
