COPPER SULPHATE

Copper Sulphate (also known as blue stone) is a copper salt found naturally as chalcanthite and made by the action of sulphuric acid on copper oxide. It usually exists as blue crystals and is used in electroplating and in plant sprays, and is used as a wash to discourage mould growth in the painting and decorating trade.
