In the 18th century, in the iron industry of Britain there was growth.
This growth we can understand through following points:
1. In 1709 AD, Abraham Derby innovated ‘Blast Furnace’, in this furnace coke was utilized. This eased the the process of melting iron elements and the work of cleaning.
2. By this process iron was melted from pig iron to wrought iron that was less brittle.
3. Henry Court invented Alloden Fumance and Cylindrical Mill, steam power was utilised in this for making refined metal.
4. Henry Bessemer discovered a method to make steel in which purer steel was made more cheaply and quickly.
5. Between 1800 to 1830 AD Britain raised the steel production four times.
