Question: what is the difference between cast iron and pig iron?
Answer: Pig Iron (also known as forged iron) is made into products (such as pots and pans) by forming a sheet of iron in a press, or by hammering. Cast Iron is made into products by pouring the molten iron into a mould. Cast Iron is thicker, heavier and brittle so it can break if dropped, whereas pig iron isn't brittle.
