Donald B. Wagner provides a comprehensive historical account of the production and use of iron and steel in China in their political and economic context. An initial chapter on the traditional Chinese iron industry introduces the important technical concepts and the ways in which technology, geography, and economics interact and influence political phenomena. Recent archaeological work indicates that the earliest production of iron in China was in the Northwest, and that the technology was introduced from the West via Central Asia. It was, however, the invention in South China of large-scale technologies which put China on a very different developmental path from that of the West. Further chapters deal with developments from the Han to the Tang, the technical evolution and economic revolution of the Song period, and economic expansion under the Ming. A final chapter investigates the debt of the modern steel industry to Chinese developments.
