Why do my silver jewelry turn black?

After a long time, it will be oxidized, and it will turn black after oxidation

Remember.

Because everyone's endocrine structure is different, some people's sweat contains more acid, some people have less, and some people's ammonia content is higher, so wearing silver jewelry produces different results, the acid is easy to black, the non-acid is not easy to black, and even some people with strong oil secretion will bring their silver jewelry to shine. Most of the silver jewelry is plated (except for a small part of the silver jewelry), so please do not use the silver cloth easily, but even if there is plating, you need to take good care, so please try not to wear silver plated jewelry when you sweat a lot. Silver blackening is a normal natural phenomenon, because the sulfur and oxides in the air and other natural media have a certain corrosive effect on silver, after wearing for a period of time, there will be some tiny spots (silver sulfide film), over time will spread into a piece, or even turn black.

Therefore, at present, silver jewelry has some discoloration due to oxidation. "It is normal for silver jewelry to turn black, but if you pay attention to daily maintenance, it is completely possible to make silver jewelry last for a long time".Another point is that you must bring it every day so that it is not easy to get dark.

If it is oxidized, it will be restored when you wash it in a silver jewelry store, and if it is the kind of silver jewelry that is plated with a layer of white gold, it will not be washed out!

The silver oxidizes and turns black, so you try to wash it with that dish soap or buy a silver cloth.

This is normal and is pure silver.

Some silver jewelry will be red after wearing it for a period of time, not because of whether its silver content is sufficient, but because the silver is oxidized, the protective coating on the surface of the silver jewelry has been gone, and the silver is directly exposed to the air, and there will naturally be the possibility of blackening, yellowing, and reddening when the silver is directly exposed to the air.

Solution: If you have just found that you can use a silver cloth to restore the brightness of the discoloration period, you can also use toothpaste or lipstick to temporarily solve it, so that the silver can be restored to its original brightness, but the time can not be kept for a long time.

Silverware itself is easily oxidized and has no necessary relationship with the physical condition, but it will be affected by the surrounding environment, so it is necessary to pay attention to less contact with cosmetics, perfumes, acids and alkalis, and vulcanized items as much as possible.

Apply a layer to the jewelryNail polishIt can prevent fading, but nail polish has a certain toxicity, and nail polish is not recommended for intimate jewelry.

The role of jewelry in life is the most important thing, but because some jewelry is very easy to oxidize, especially silver jewelry, so applying a layer of transparent nail polish can still slow down the oxidation reaction.

It can play a certain anti-discoloration effect.
