Iron Extraction and Purification / Steel | ChemKey

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.
