Puddling process

Definition

The puddling process is a method of converting pig iron into wrought iron by heating it in a reverberatory furnace and stirring it to oxidize impurities. This innovative technique significantly improved the quality and malleability of iron, playing a crucial role during the Industrial Revolution as it allowed for the production of stronger and more versatile materials essential for machinery and infrastructure.
