The Oxford Iron Furnace - Built 1741 - Oxford, NJ

The Oxford Iron Furnace

Represents the early development of the iron industry in the United States during the 18th and 19th centuries. The furnace was built in 1741 and was in operation until 1884, producing iron for various purposes such as weapons, tools, and machinery. The furnace is notable for its use of charcoal as a fuel source, which was the primary fuel used in iron production during the colonial period. The furnace also utilized a blast mechanism, which was a significant technological advancement at the time, that increased the efficiency of the iron production process.

The Oxford Iron Furnace also played a crucial role in the American Revolutionary War, as it supplied iron for weapons and ammunition used by the Continental Army. Additionally, the furnace was operated by skilled ironworkers, many of whom were enslaved Africans, highlighting the important role that enslaved labor played in the early American economy.

Located in Scranton, Pennsylvania, the furnace was one of the largest and most productive iron furnaces in the country during its period of operation. The Scranton Iron Furnace played a crucial role in the growth of the iron and steel industry in the region, providing the raw materials needed for the construction of infrastructure, such as bridges and railroads, that helped to spur economic growth and industrialization.

The Scranton Iron Furnace also represents an important period in the history of American labor, as it was one of the first sites to employ a large number of immigrant workers from Ireland and other countries. These workers faced difficult working conditions and low wages, but their efforts helped to lay the foundation for the growth of the American middle class. The Scranton Iron Furnace is now a historic site, preserved as a monument to the country's industrial heritage, and serves as a reminder of the sacrifices and contributions of the workers who helped to build the United States into the industrial powerhouse it is today.
