The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesn't shrink much when it solidifies. It is therefore ideal for making castings – hence its name. However, it is very impure, containing about 4% by weight of carbon. This carbon makes it very hard, but also very brittle.

Carbon appears significant role in affecting the brittleness and hardness balance in Iron. To further reduce the Carbon content of pig iron, the pig Iron is melted again with scraps of Iron and Coke. This kind of Iron is called Cast Iron and has a lower Carbon content of 2-3 %. Cast Iron is harder than pig iron. Part 2:
