This furnace was the focal point of a pre-Industrial Revolution industry town, one of hundreds of furnaces that thrived and failed in the 19th century. The Maryland Iron Company (incorporated 1828) built this furnace along the Nassawango Creek roughly four miles northwest of the Pocomoke River to produce pig iron by the cold-blast process. In 1836-37 the furnace changed ownership several times, until Thomas Spence of Worcester County purchased it and began producing pig iron at a rate of 700 tons a year. Spence is credited with the installation of the hot-blast stove.
