puddling process

Method of converting pig iron into wrought iron by subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances (see oxidation-reduction).

Invented by Henry Cort in 1784 (superseding the finery process), it was the first method that allowed wrought iron to be produced on a large scale.
