View of molds being removed from steel ingots after they have solidified at an unknown manufacturing plant. During the production of metals, such as iron and steel, molds are typically used to form ingots, pieces of relatively pure material cast into shapes suitable for further processing. This photograph is one of a set of fourteen stereographs detailing the production of iron and steel by various processes.</div>
