in the mid-19th century.
Hopewell Furnace operated as part of a complex network of furnaces (turning iron ore into iron and producing cast iron products), forges (refining cast iron into wrought iron products), mines, and markets in southeastern Pennsylvania and beyond. This map shows some of the mines and ironworks wholly or partly owned by the same men who owned Hopewell Furnace in the 1830s.
1. Locate Hopewell Furnace and Philadelphia on Maps 1 and 2.
2. The map key on Map 2 identifies other categories of iron-related sites. How many can you locate that are within 10 miles of Hopewell? Why were there so many furnaces and forges in this region?
3. Early 19th-century iron-making required easily mined iron ore, a dependable water supply to provide the blast for the furnace, extensive hardwood forests for charcoal, and limestone to remove the impurities from the ore. Which of these are easily identified on Map 2?
4. Success in iron making required markets where products could be sold and transportation to get them there. Using Map 2, identify cities that might have served as markets. Use the map key to calculate how far these cities were from Hopewell Furnace. What means of transportation to carry iron products to these markets can you identify on Map 2?
