Silver shines in its splendor without any effort
Silver cutlery, jewelry or other antiques from silver will get a black layer after some time. Also known as silver sulfide. Previously they needed house staff to let the objects shine again in their glamor. Today, several simple means are used to aid the polish by a chemical action.
Required materials for cleaning with aluminum foil
- 1 pot
- 1 liter of water
- Six tablespoons of cooking salt
- One piece of aluminum foil (slightly larger than the pan)
How is the silver cutlery cleaned with aluminum foil?
- The cup is first filled with 1 liter of water, and six tablespoons of cooking salt (sodium chloride) are added. This solution is heated until it boils.
- Now put the not too tightly pressed aluminum foil in one piece into the water.
- Then the silver cutlery, on which silver sulfide has spread on the surface, is put into the pot or laid. In the case of the cleaning, it is of particular importance that the object gets in contact with the aluminum foil. Within a short span of time, the black layer disappears, and the silver cutlery returns to its original luster.
The sulfur compounds produced during the purification are characterized by an unpleasant smell (rotten eggs or garlic). The aluminum foil turns black and becomes black. This is probably because there is no decomposition with metals alloyed with aluminum.
