    History of the iron and steel industry in the United States

    In the late 1700s the iron furnaces moved away from the bog iron ore of the coastal swamps, to larger iron ore deposits further inland. Inland locations also allowed the furnaces to be closer to sources of limestone, which was used as a flux in iron smelting. The proximity to larger ore deposits favored larger, more permanent iron smelters.
