Iron Plantations: the Manufacture of Iron in the Province of Maryland

Introduction

Principio FurnaceIn the Assembly Proceedings, May 14-June 6, 1719, the Maryland Assembly was quite clear about why they thought the government should support the establishment of iron furnaces and forges: “to the Increase of our Trade and Navigation, the Peopling of this Province, and to the Advantage of his Lordship, by the Encouraging the Taking-up such remote and barren Lands as are now entirely useless and uncultivated.”  They were trying to insure the economic health and viability of the colony.  The first furnace in Maryland to go into blast was located in present-day Cecil County. In 1725, an English stock company, Principio, brought its furnace and produced its first pig iron.  Marylanders began accruing wealth from iron when the Baltimore Company, a partnership of five leading Maryland men, began producing pig iron in 1734 on the Patapsco River near Mount Clare.  As Maryland expanded westward, iron manufacturing also moved westward.  Today Maryland is dotted with the remains of iron furnaces and forges from its iron heyday.

The production of pig iron was seen as perfect fit within the mercantile system which governed the relationships of the colonies with England.  Raw materials in England were becoming depleted.  English producers of pig iron could not satisfy the demands of British manufactures of finished iron products.  To meet their needs, these companies imported pig iron from Sweden which was considered one of the premier manufactures of pig iron.  However, relations between the two countries would vacillate between strained and hostile.  Colonial sources of iron were seen as a much safer source if the quality of colonial iron was equal to that of Sweden. Maryland with its dispersed population and no local market needed a market such as Britain in order to succeed.

The distance between the market and its source, colonial manufactures needed to keep their manufacturing costs as low as possible; otherwise, they risked losing money when the pig iron finally sold in England.  For that reason, many iron works in Maryland used slave, indentured, and convict labor.  They were able to keep the cost of procuring iron ore low because many of the deposits along the western shore were close to the surface.  On the eastern shore iron formed in bogs.  With an abundance of forested land, charcoal production costs were kept to a minimum.  The bay provided lime in the form of seashells.  The rivers and Chesapeake Bay provided easy transportation of raw materials and the finished product.  Operating an iron works was a risky proposition.  The success of these ventures depended on the expertise of its founder, skillful management by its iron master, and the vagaries of an international market.
