There are many kinds of silverware, including 999 silver, 925 silver, Miaoyin, Tibetan silver, Thai silver and so on. Usually, sterling silver is often referred to as 999 silver, while 925 silver is also sterling silver. 925 silver refers to silver jewelry containing more than 92.5% of silver, while in China, the amount of silver is not less than 99% is called "foot silver." It is also sterling silver.
So, will sterling silver turn black? Older generations have experience, silver jewelry will be black! Especially the 99 silver jewelry is more likely to black.
Why is sterling silver black? The human body's sweat contains sulfur, ammonia and other compounds, and some air also contains hydrogen sulfide, nitrogen monoxide and other substances, which will cause the surface of the silver jewelry to be oxidized, and then discolored and tarnished. But some people will say that some people wear silver jewelry not only will not turn black, but sometimes it will become more luminous. This is because the skin is often in contact with the skin or rubbed against the clothes, and the silver scale on the surface of the silver jewelry is rubbed off. Therefore, silver jewelry should be worn frequently. When not wearing, it is best to wrap it with closed articles to avoid oxidation with air.
But this kind of silver jewelry is not black, don't worry, just use a silver cloth to rub it again and shine as new, or use toothpaste to clean it and restore the brightness. Or cleaning and processing in jewelry stores around the world.
925 silver is less susceptible to oxidation than 999 silver, because 925 silver has been added with other elements in the production process, making 925 silver more resistant to oxidation and easier to make beautiful styles. Most of the silver jewelry brands currently on the market use 925 silver. Craftsmanship.
However, there are many miscellaneous brands on the market, and there are many inferior ornaments. These types of sterling silver are actually very low in silver content. They even use alloys to impersonate sterling silver jewelry. These jewelry will not be used for a long time and will turn yellow and black. How to clean it is useless. Therefore, real silver is not afraid to wash! Good things are not afraid to use!
