The story of the introduction and growth of the technology of metals in the North American colonial period entails significant developments beyond the transfer of the technology from the Old World to the New. In the struggle to create an indigenous industry, in the efforts to encourage and support the work of metals craftsmen, in the defiance of British attempts to regulate manufacturing of metals, the colonial society developed a metals technology that became the basis for future industrial growth. The author traces colonial industrial development from the sixteenth through the eighteenth centuries in nine chapters: “Before Jamestown,” “Metals in the Early Colonies,” “Copper in the Colonies,” “Colonial Iron: The Birth of an Industry,” “Metals Manufacture in the Colonial Period,” “Colonial Iron: Regulation and Rebellion,” “Metals and the Revolution,” “The Critical Years,” and “Reflections on the End of an Era.”
