The basis for charcoal-fueled iron production in southern New Jersey was limonite, better known as bog iron. This form of iron was created in a chemical reaction between the tannin-rich waters of the Pine Barrens and underlying iron rich sands and marls. The bog iron ore would rise up to the various creeks, rivers, and lakes of southern New Jersey.
