View of a line of furnaces in an open hearth mill at an unknown manufacturing plant. During the conversion of iron into steel, raw materials such as molten iron are "charged" or deposited into the interior of a furnace, which burns out excess carbon and other impurities to form steel. This photograph is one of a set of fourteen stereographs detailing the production of iron and steel by various processes.
