Greenwood Furnace State Park

Before the age of railroads, the basic ingredients of iron production needed to be nearby. That explains why furnaces were built in rural settings surrounded by the necessary raw materials.
A source of iron ore was essential.
As the furnace fires burned, limestone separated impurities from the molten iron. Huge forests supplied wood for charcoal, a fuel that burned with intense heat.
A stream or creek provided water power to operate machinery designed to fan the charcoal fire, raising its temperature to nearly 3,000 F.
(Inscription under the image in the lower left) Mule drawn wagons loaded ore, limestone, charcoal and pig iron.
(Inscription above the image in the upper right) Some iron ore was found near the surface while other deposits required miners to descend into tunnels as long as 200 yards.
(Inscription under the image in the lower center) Colliers built conical mounds of wood, then set them afire.
(Inscription under the image in the lower right) A controlled slow-burning fire changed wood into charcoal.
