View of two workers constructing sand molds for pig iron, an intermediate product of smelting iron ore produced from a blast furnace, at an unknown manufacturing plant. Used to form pig iron ingots, such molds are traditionally formed in sand and feature a branching structure meant to resemble a litter of piglets being suckled by a sow. This photograph is one of a set of fourteen stereographs detailing the production of iron and steel by various processes.
