The standard of living has improved, people have begun to enjoy, and some accessories that were once difficult to see have become very common. For example, silver jewelry is a favorite ornament for many people, because people believe that silver jewelry has the effect of exorcizing evil spirits. And because of the TV series, many people think that the color of silver items is exposed to toxic substances.
Therefore, many friends in their lives think that the reason why silver jewelry is discolored is because the toxins in the body are washed out. but it is not the truth. A variety of silver jewelry appears discolored after being worn, not because the toxins inside the body are sucked out, but because of the oxidation of the air.
1. Can silver jewelry be used for drugs?
Many people may not believe that the silver element does not have the effect of adsorbing toxins. In various novels, dramas, and film and television works, it is misunderstood that silver is black and toxic. If you want the method of blackening silver, it is very simple, just use the element of "sulfur", which is widely contained in cooked eggs and kiwi. Some sulphur-free foods won't turn black even if they come into contact with silver jewelry.
Usually, the sulfur-containing articles, the food and the silver material are in contact with each other to cause a redox reaction, so that a black "silver sulfide" is formed on the surface of the silver article. In the case of boiled eggs, cut the cooked eggs in half. If there are silver earrings placed in the eggs, the earrings will turn black in a few minutes. We saw the silver needle in the TV series. This is a principle like this. This is actually a misunderstanding and needs everyone to pay attention.
Second, why the silver jewelry turned black
So many people have such doubts. Why do we wear silver jewelry that will change its surface to a color in a period of time, from the previous silvery white to black, is it because we are poisoned?
In fact, this is not the case. There is no relationship between poisoning and poisoning. The premise of poisoning is that silver jewelry should be in contact with substances containing sulfur, which causes it to turn black.
So what is the cause of blackening silver jewelry? At this time we have to consider a problem, that is, the oxidation of air.
As a kind of metal substance, the activity of silver is not iron active. Generally speaking, iron articles in the air for a long time, there will be rust and corrosion, while silver articles are rare, but the oxidation reaction is still not possible. Avoided.
When we wear silver jewelry, there will be sweating. There is too much sulfur and ammonia in the sweat, and there are many gases in the air that we can't see, such as carbon monoxide and sulfur monoxide.
These substances will oxidize and react with silver jewelry unconsciously, causing the surface of the silver jewelry to be oxidized, causing the color of the silver jewelry to change and lose its luster.
In addition, in the research, the speed of blackening of silver jewelry is very much related to the pH of people's sweat. The more sweat, the more obvious the acidity of the silver jewelry, the faster the silver jewelry will change.
At the same time, some silverware will cause it to react with the air because it will not be used too much. It will cause blackening of varying degrees. It is also common to lose luster.
Third, how to do silver jewelry black
Then, in the case where the silver jewelry worn in life is blackened, what should I do?
1, wipe with a cloth
Cleaning silver jewelry is something that many people will do. In fact, it is not obvious that silver jewelry appears to be black. At this time, the cloth is wiped, and the brightness of the silver jewelry can be restored during the wiping process.
When choosing a cloth, do not use a strong cloth. There is a silver cloth on the market for rubbing silver jewelry. Such items are helpful for protecting silver jewelry.
2, with silver wash water
Silver-washed water is an item that many people like to use in recent years. The use of silver-washed water can wash away the black mark on silver jewelry. However, such items should not be used when it is absolutely necessary. This is because the silver-washed water has Two-sidedness.
On the one hand, it can effectively wash away the imprint on the silver jewelry, on the other hand it will corrode the silver jewelry, causing the silver jewelry to lose its luster, which is undoubtedly something that many people do not want to see.
Fourth, the benefits of wearing silver jewelry
So what are the benefits of wearing silver jewelry in life? Silver jewelry can not only make people look beautiful, proper wearing silver jewelry is also very helpful for sterilization and anti-inflammatory.
Silver jewelry is an inactive metal. It does not chemically react with the skin at normal temperature. It has a certain effect on sterilization and disinfection. It may be appropriate to wear some.
Through the above simple description about the blackening of the surface of silver jewelry, I believe that everyone has a better understanding of the reasons for the blackening of silver jewelry. At the same time, it has made a description of the misunderstanding of silver jewelry blackening, and hopes to help everyone. In life, the scientific wearing of silver jewelry has unexpected benefits for health care.
