The reason why silver jewelry turns black over time is that silver is an unstable element that easily reacts chemically with sulfur, leading to blackening.Silver sulfide forms. Human sweat contains a lot of sulfur, and when it comes into contact with silver jewelry, it will react.Moreover, if a person is in some polluted environments where there are many acidic gases, sulfur dioxide, nitric oxide, and other compounds in the air, it can also cause silver jewelry to tarnish.Even under normal circumstances, if silver jewelry is worn for about half a year, the surface will oxidize and the color will become dull and lose its luster. It is normal for silver jewelry to turn black due to the sulfur and oxides in air and other natural media that corrode silver. After wearing it for a while, small spots (silver sulfide film) will appear, which will eventually spread into patches or even turn black over time.Therefore, currently some silver jewelry exhibits discoloration due to oxidation.Here are some suggestions: Maintenance knowledge: Most consumers know that silver can turn black, but they don't know how to prevent it from turning black or what to do if it does - this is the root cause why some consumers are reluctant to buy silver jewelry.Therefore, teaching how to maintain and remove oxidation from silver jewelry surfaces and restore its luster is what builds consumer confidence in purchasing.The main points to be achieved are as follows: ① When wearing silver jewelry, avoid wearing other precious metal jewelry at the same time to prevent collision, deformation, or scratches.② Avoid contact with water vapor and chemicals, and avoid swimming while wearing it, especially in the sea. ③After wearing it every day, wipe it clean with cotton cloth and store it in a jewelry box or bag for safekeeping. ④ It has oxidized and turned black; you can use a soft-bristle brush dipped in toothpaste to clean it, or you can scrub it with soap or detergent by hand.If it's really dirty, use silver cleaning water to scrub it. After cleaning, always dry it with a cotton cloth. Shengxing Silver Jewelry is a professional manufacturer of pure silver jewelry, with pure silver 99 and 999 purity.
