Iron and Industrial Revolution in Britain. Early iron smelting used charcoal as both the heat source and the reducing agent. By the 18th century, the availability of wood for making charcoal had limited the expansion of iron production, so England became increasingly dependent on Sweden (from the mid17th century) and then from about 1725 on Russia for the iron required for industry.
