Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content typically 3.54.5 which makes it very brittle and not useful directly as a material except for limited applications
