Wrought iron process that drove UK success was appropriated from black metallurgists, records suggest

An innovation that propelled Britain to become the world’s leading iron exporter during the Industrial Revolution was appropriated from an 18th-century Jamaican foundry, historical records suggest.

The Cort process, which allowed wrought iron to be mass-produced from scrap iron for the first time, has long been attributed to the British financier turned ironmaster Henry Cort. It helped launch Britain as an economic superpower and transformed the face of the country with “iron palaces”, including Crystal Palace, Kew Gardens’ Temperate House and the arches at St Pancras train station.
