Pig iron is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%,

Wrought iron is an iron alloy with a very low carbon content in contrast to that of cast iron, or 0.25% for low-carbon "mild" steel. Wrought iron is manufactured by heating and melting high-carbon cas

…molten iron. The temperatures are considerably higher: more than 1,538 °C (2,800 °F), which is the melting temperature of iron. Smelting and producing wrought iron were known in ancient Europe and the Middle East, but it was produced in bloomeries by direct reduction. Small prills of pig iron dispersed in slag are…
