       The sand in its natural or moist state is called green sand. It is also called tempered sand. It is a mixture of sand with 20 to 30 percent clay having total amount of water from 6 to 10 percent. The mould prepared with this sand is called green sand mould which is used for small size casting of ferrous and non-ferrous metals.
