- Puddled iron is a material produced through the process of converting pig iron to bar (wrought) iron1. In this process, molten pig iron is stirred in a reverberatory furnace in an oxidizing environment to burn the carbon, resulting in wrought iron1. Puddled iron behaves differently from modern steel and was used in the construction of the Eiffel Tower2.Learn more:✕This summary was generated using AI based on multiple online sources.
