    How Iron Was Made - Saugus Iron Works National Historic

    May 29, 2020 Introduction. Iron making evolved over a few thousand years. Using the ancient bloomery method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the direct process.

    Puddling produced structural-grade iron at a relatively low cost. It was a means of decarburizing pig iron by slow oxidation, with iron ore as the oxygen source, as the iron was manually stirred using a long rod. Puddling was done in a reverberatory furnace, allowing coal or coke to be used as fuel.
