The correct answer is: C. White forge pig
Pig iron is a type of iron that is cast into ingots, or pigs, before being further processed. It is produced by smelting iron ore in a blast furnace. The type of pig iron used for the manufacture of wrought iron is white forge pig. White forge pig is a high-quality pig iron that is free of slag and has a low sulfur content. It is ideal for use in the manufacture of wrought iron because it produces a strong and ductile product.
Bessemer pig is a type of pig iron that is produced by the Bessemer process. The Bessemer process is a steelmaking process that uses a blast of air to oxidize the impurities in pig iron. Bessemer pig is a low-quality pig iron that is high in carbon and sulfur. It is not suitable for use in the manufacture of wrought iron.
Grey or foundry pig is a type of pig iron that is produced by the blast furnace process. The blast furnace process is a steelmaking process that uses coke, iron ore, and limestone to produce pig iron. Grey or foundry pig is a low-quality pig iron that is high in carbon and silicon. It is not suitable for use in the manufacture of wrought iron.
Mottled pig is a type of pig iron that is produced by the blast furnace process. Mottled pig is a medium-quality pig iron that is high in carbon and silicon. It is not suitable for use in the manufacture of wrought iron.
