The silver bracelet turns black and you are sweating. Sweat contains a lot of sulfur, which does not matter, but the sulfur content in sweat varies from person to person. There are also some external factors, such as smoking all the year round, being used to spraying heavy makeup, often using sulfur soap, and enjoying hot springs. How to make silver bracelets brighter and brighter?
If the wearer has the habit of small gestures, it is possible to make the silver bracelet brighter and brighter. For example, you always wipe. "Radioactive" gold attaches importance to the radioactivity of gold and silver jewelry, but it is not the gold itself but its isotope that is radioactive. All elements have isotopes, and gold is no exception, but it usually takes about a year for gold to stabilize.
However, gold ores and silver ores usually contain radioactive elements such as cobalt, polonium and radium. In the process of mining, smelting and making jewelry, a small amount of radioactive substances may remain on jewelry, which is harmful to human body. Even so, qualified gold and silver processing plants are still processing to reduce radioactivity.
Pure gold and sterling silver jewelry have fewer allergic symptoms, while alloy jewelry has more allergic symptoms. First of all, the surface of alloy jewelry is usually plated with pure gold or pure silver, but after long-term friction with the skin, nickel, chromium, lead and other components in the jewelry will be exposed, thus irritating the skin. Secondly, the sweat discharged by the human body is acidic, which will decompose the coating on the surface of jewelry, thus causing harm to the skin. When wearing silver jewelry, don't wear other precious metal jewelry at the same time to avoid collision, deformation or scratch. Avoid contact with water vapor and chemicals, and avoid swimming, especially going out to sea.
