Cornwall Iron Furnace

Location: Lebanon, PA, USA
Date: 1742
Creator(s): Grubb, Peter
When erected by Peter Grubb to smelt the rich iron ore of the nearby Cornwall ore banks, this stone-built blast furnace was typical for its time, producing about 20 tons of pig-iron and cast-iron products a week. A major reconstruction in 1856 to 1857 produced important changes: the furnace itself was enlarged; the blast-air bellows were replaced by a pair of wooden cylinder "blowing tubs"; the waterwheel that had powered them was replaced by a 20-horsepower steam engine; and a pair of waste-heat boilers to supply the engine was built into the open stack of the furnace. Cornwall is one of hundreds of nineteenth-century charcoal-fueled blast furnaces in the United States to survive fully intact
