Coal, Steam, and Iron

Coal, Steam, and Iron Ingredients for an Industrial Revolution Coal The Iron Age started 3000BCE

Iron was first made from iron ore and charcoal. The process used huge amounts of wood for fuel and helped deplete forests

near populated areas. It took until the 18th century to make iron with coal Now iron could be made in larger amounts Iron was used to produce machines that

replaced human labor Increased demand for iron meant increased demand for coal But, back at the coal mine

Greater demand for coal to make more iron meant mining to new depths Problemhow to keep mines from flooding

Solution to flooded mines The Newcomen pump used a wood fire to power a large piston that pumped water from the mines.

Later, coal was used to fuel the fire The ability to pump water from mines increased coal production.

Needed more coal to run the pumps More coal meant more iron could be produced Sixty years later, James Watt made changes that lead to the steam engine

Watts adapted his steam pump for other uses The steam engine was used to mine more and more coal Rising demand for coal to make more iron

Rising demand for iron to make more engines and other machinery Lead to. a Transportation Bottleneck

Wooden railways The first railways in Great Britain were built in the early 17th century, mainly for transporting coal from the mine to the water where it could be loaded on to a boat. These had wooden rails. However, the rails wore out and had to be replaced often. In 1768,

the Coalbrookdale Company laid cast iron plates on such wooden rails to provide a more durable surface. The wooden trains were pulled by horses. With modifications from others, Watts steam engine began a new era in transportation The Bottleneck was opened.

The opening of the Liverpool and Manchester Railway in September 1830 was one of the key events of 19th century England. It was the first railway, which used steam locomotives, and the first to link two major cities The steam engine railroad was an

instant success and the age of railroad building began Coal Iron

Railroads The demand for each depended on availability of the others.

All three were necessary for industrialization
