Information about Puddled Iron
Puddle iron is a type of wrought iron. Its production process was invented at the end the eighteenth century, following an increase in the need for wrought iron. It is produced in a puddling furnace. The process results with an iron that contains a slightly increased carbon content compared to wrought iron. This provides it with a higher tensile strength. The puddling furnace also allows a better control of the chemical composition of the iron. The Eiffel Tower was built with puddle iron for a large part of its structure. Other standing structures such as bridges also used puddle iron. This is a very pure form of iron, used mainly in construction.
Wrought iron is commercially pure iron, having a very small carbon content (not more than 0.15 percent), but usually containing some slag. It is tough, malleable and ductile and is easily welded. However, it is too soft for blades.

Puddling was an Industrial Revolution means of making iron and steel. In the original puddling technique, molten iron in a reverberatory furnace was stirred with rods, which were consumed in the process.
