It was developed in England during the 1780s. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment to burn the carbon, resulting in wrought iron.www.wikiwand.com/en/articles/Puddling_(metallurgy)

In this paper we examine quantitatively, using modern thermodynamics and kinetics, this ‘wet puddling’ process, aiming to highlight its originality and importance.
- As soon as the metal has ‘cleared,’ the puddler brings on the boil by adding some mill scale. To keep the phos-phorus from reverting to the metal, he initially maintains a smoky, reducing atmosphere by keeping the damper low. The bath is hard to stir, but after about 10 minutes of strenuous stirring, the bath becomes more fl uid. Carbon in the pig ...
