View of an apparatus for applying a coat of lime onto molds filled with pig iron, an intermediate product of smelting iron ore produced from a blast furnace, at an unknown manufacturing plant. When processing iron ore into steel, lime forms a highly basic slag, a stony waste matter that is separated in order to refine or purify the iron ore. This photograph is one of a set of fourteen stereographs detailing the production of iron and steel by various processes.</div>
