Coal in the Industrial Revolution
Coal and Iron . Darby was the first person to use coke – a form of processed coal – to smelt iron in 1709. This advance spread slowly, largely due to the cost of coal. Other developments in iron followed, and these also used coal. As the prices of this material fell, so iron became the major coal user, increasing demand for the substance ...
