For electroplated silver jewelry is that The inner layer is silver, the surface is processed with electric current treating; generally, electroplating consists of gold plating and platinum plating;
the method for differentiation is that, surface luster of silver is bright, like a mirror surface, with good reflective effect, and is inactive to oxidation. Method for simple treatment of electroplated silver jewelry is as follows:
① Buy a packet of alum from the nearest pharmacy of traditional Chinese medicine or drug store.
② Then boil silver jewelry in < 10 parts of water: 1 part of alum > solution (Boiled water).
③ Take out silver jewelry, put it into cold water, clean with soft brush (E.g. toothbrush) dipping toothpaste, laundry lotion or salad removing agent.
④ Dry with hair dryer, then wipe with chamois leather to restore brightness as new one.
For non-electroplated silver jewelry: Loss of luster due to vulcanization (Airborne sulfur dioxide and silver are chemically reactive to produce a layer of silver sulfide on silver jewelry, the same principle as blackening of cut apple). Method for simple treatment of non-electroplated silver jewelry is as follows:
① Bake silver jewelry on fire, to destroy tissue structure of silver surface, duration of baking depends on the size and thickness of silver jewelry, which is called firing).
② Cool down, then put it into alum water for cooking, then take it out after boiling, put it into cold water, and clean with soft brush (E.g. toothbrush) dipping toothpaste, laundry lotion or salad removing agent.
③ Dry with hair dryer, finally, clean with silver cleaning cloth or silver powder to restore silver color (Remark: This method is not applicable to following silver jewelry: a. silver jewelry set with plastic and the like/b. vulcanized silver jewelry (Vulcanization: That is, in buying silver jewelry, the black part includes totem pattern or black inscribed letters).
Another tip to brighten silver jewelry is recommended for your reference: If you want to brighten your newly bought silver jewelry, and to avoid its blackening, apply a thin layer of clear nail polish on the surface, afterward, apply once for every ten days; if you want to remove the nail polish, soak silver jewelry in lacquer thinner and then clean with water.
Electroplating is a method to put a metal coating onto an object, in our case a piece of jewellery, by placing it in a solution containing the metal to be plated and passing an electrical current through the piece and the solution. It is possible to electroplate coatings of most pure metals and even some alloys.
Electroplating is a comparatively quick and easy process to carry out and does not require major investment in costly equipment. It can be done successfully with very simple, basic equipment.
Silver-plated jewelry has a thin layer of silver over a non-precious metal base. Because the silver-plating is so thin, you need a very gentle cleaning method:
1. In a large bowl, fully dilute a few drops of mild dish soap in warm water. (Undiluted dish detergent will leave dark spots on the silver.)
2. Submerge your item in the soap water and gently rub it with your fingertips to release the tarnish.
3. Rinse the piece under warm water to remove any soap reside.
4. Dry the jewelry with a soft lint-free cloth.
5. Gently buff the jewelry’s surface with a polishing cloth to bring out its luster and shine.
