During the eighteenth-century, Britain was the hub of the international market in iron. Although the British Isles could boast a well-established domestic iron industry, native ironmasters were unable to meet the rapidly growing demand for iron in the major metalworking districts of the Midlands and the north. As a result, large quantities of bar iron had to be imported from the Baltic to meet the shortfall. Much of this iron, destined for the West Midlands, was shipped through Bristol. In this article, Chris Evans looks at Bristol’s iron trade through the business records of Graffin Prankard, a Bristol merchant who played an important role in this commerce in the first half of the eighteenth century.
