Henry Cort discovered the puddling process for making wrought iron. The
puddling process converted pig iron into wrought iron by subjecting it to heat and
stirring it in a furnace, without using charcoal. It was the first method that
allowed quality wrought iron to be produced on a large scale. Cort’s invention
had tremendous impact on the iron industry and helped significantly increase England’s
production.
