With the development of society, diamond jewelry is increasingly sought after by young people, but its price is relatively expensive, which makes many people turn their attention to the silver jewelry that has been cherished by people since ancient times. Silver can be blackened during the wearing process. Why does the silverware turn black? So what are the reasons for the blackening of silver? Let's take a look at it below!
Blackening of silver is a natural phenomenon. Because of the corrosive effects of sulfur and oxides in air and other natural media, some tiny spots (silver sulfide film) appear after wearing for a while. It will spread into pieces and even become black for a long time. Therefore, at present, silver ornaments have some discoloration due to oxidation.
Since silver is chemically active, it easily reacts with elements such as sulfur to become sulfides. After a long time, the compound forms a black silver sulfide film on the surface of the silver finish. Of course, at the beginning, it will appear as some subtle mottled, then slowly disperse into pieces, and finally affect the luster of the appearance color.
The human body's sweat contains compounds such as sulfur, and some air is also rich in hydrogen sulfide and other substances, so that the appearance of silver ornaments will be oxidized, causing blackening.
The process of oxidizing silverware is unavoidable. Some glossy silver faces will touch the skin when worn, so in this situation, not only will it not turn black, but sometimes it will become brighter and brighter. Of course, the silver pattern with complicated patterns can not be cleaned up in the gap, so it is better to say that the simple style is oxidized.
Chemicals and other things can cause damage to silver jewelry, so whether you are taking a bath, washing clothes, or swimming, try to get silver jewelry. To slow down the process of being oxidized.
Silver is closely related to people's lives and becomes an inseparable part. In ancient times, it was not only used to create silver, but also became a currency. But with the development of society, it has become a medical necessity. Therefore, its preciousness cannot be measured by other things. However, it is also necessary to prevent the blackening of the silverware. Here, this article focuses on the reasons why the silverware turns black. I hope that you can master these reasons so that you can better care for your jewelry.
