Iron Making

The tough, malleable wrought iron needed for plow moldboards, nails, and horseshoes had to be obtained through an indirect process not in place at Hopewell. The molten iron was cast into pig iron bars shipped elsewhere for refining. At the finery forge, the iron was remelted and much of its carbon was oxidized, raising the melting point.
