Building the infrastructure to support the Industrial Revolution wasn't easy. The demand for metals, including iron, spurred industries to come up with more efficient methods for mining and transporting raw materials.
Over the course of a few decades, iron companies supplied an increasing amount of iron to factories and manufacturing companies. To produce the metal cheaply, mining companies would supply cast iron rather than its expensive counterpart -- wrought iron. In addition, people began to use metallurgy, or the deeper investigation of materials' physical properties, in industrial settings.
Mass producing iron drove the mechanization of other inventions during the Industrial Revolution and even today. Without the iron industry's assistance in the development of the railroad, locomotive transportation may have been too difficult or expensive to pursue at the time.
