Silver is a metal used widely in the jewellery industry because of its versatility and beauty. However, silver is a metal susceptible to tarnish. Below is one method for getting your silver gleaming once again.
What you need:
500ml hot water (but not hot enough to burn)
1 tablespoon of salt.
Some (preferably recycled) aluminium foil.
1. Pour the hot water into the bowl.
2. Stir in 1 tablespoon of salt.
3. Tear off some strips of aluminium foil and add it to the bowl.
4. Submerge the jewellery in the solution and leave for 5 minutes. If the silver is heavily tarnished the process may need to be repeated a few times.
How it works:
Silver tarnishes when the surface of the silver combines with sulphur in the air. The black substance created is called silver sulphide. When placed in a saline solution, in the this case the hot salt water, a chemical reaction occurs between the aluminium and silver sulphide, removing the silver sulphide from the silver surface.
