Furthermore, the presence of phosphorus (without carbon) produces a ductile iron suitable for wire drawing, for piano wire.Wrought iron has been used for many centuries, and is the “iron” that is referred to throughout western history.Pig iron and cast iron have high carbon content which make them very brittle, but they have a lower melting point than iron or steel.Cast and especially pig iron have excess slag which must be at least partially removed to produce quality wrought iron.Air was blown in through a tuyere to heat the bloomery to a temperature somewhat below the melting point of iron.In the course of the smelt, slag would melt and run out, and carbon monoxide from the charcoal would reduce the ore to iron, which formed a spongy mass. If the bloomery was allowed to become hot enough to melt the iron, carbon would dissolve into it and form pig or cast iron, but that was not the intention.

It is nearly pure but contains some slag in the form of filaments.These too are now obsolete, and wrought iron is no longer manufactured commercially.Wrought iron was originally produced by a variety of smelting processes, all described today as bloomeries.After smelting was complete, the bloom was removed, and the process could then be started again.It was thus a batch process, rather than a continuous one such as a blast furnace.

Wrought iron is tough, malleable, ductile and easily welded.
