1. Reasons for Silver Jewelry Turning Black It is normal for silver jewelry to tarnish due to sulfur and oxides in the air and other natural media that have a certain corrosive effect on silver.When silver jewelry is worn for a long time, sulfur combines with silver to form a black silver sulfide film on the surface of the jewelry. This initially manifests as small spots, and as the sulfide phenomenon intensifies, it slowly spreads into patches, forming what is commonly known as silver tarnish. It turns black and affects the surface luster of the jewelry, which people often mistakenly think is discoloration. Its chemical reaction equation is: 4Ag+H2S+O2=2Ag2S+2H2O 2. How to clean silver jewelry after vulcanization? Squeeze a little toothpaste, add a little water and knead until you create a rich foam. Use a soft cloth to wipe until it shines brightly. Use a fine soft-bristle toothbrush to clean the gaps, then rinse with water.For complex components and chains, you can soak them in foam toothpaste water and gently rub them repeatedly, then rinse them with clean water.When sulfurization is severe, you can use professional silver cleaning solution.Although silver cleaning solution claims to be "non-damaging to silver," it is a chemical agent after all. It is recommended not to use it unless absolutely necessary. 3.How to maintain silver jewelry daily? The best way to maintain silver jewelry is to wear it every day because the body's oils can make the silver shine with a warm and natural luster (although there are exceptions, some people's sweat contains substances that can cause silver to tarnish).When wearing it, use a soft cloth or silver polishing cloth to wipe the surface of the silver jewelry daily to maintain its shine and dryness.When not wearing, gently wipe the surface with a soft cloth to remove moisture and dirt, and store in an airtight bag to prevent oxidation and blackening of the silver jewelry surface due to contact with air.
