Problem description:

I often see this situation.

Some people say that it is because there are toxins in the body;

Others say it is because of oxidation.

What is the reason?

Analysis:

The blackening of silver ornaments is a normal natural phenomenon. Because sulfur and oxides in natural media such as air have a certain corrosive effect on silver, after wearing for a period of time, some tiny spots (silver sulfide film) will appear, which will spread into pieces or even turn black over time. Even if a protective film is electroplated on the surface of jewelry, it will still be oxidized if it is not paid attention for a long time. Therefore, at present, silver jewelry has some discoloration due to oxidation. However, if you pay attention to the following points, you can extend the bright period of your precious jewelry.

Avoid putting silver jewelry with hair gel, perfume, skin care products, soap, etc. , will make silver jewelry and jewelry dim or even black.

Take off all kinds of jewelry in time when washing and bathing to prevent jewelry from encountering alkaline products.

In particular, chlorine-containing bleach will react with silver after contact, which will make silver ornaments turn black quickly.

When silver ornaments and jewels are not in use, they should be thoroughly dried before storage to avoid losing their luster due to moisture.

For silver ornaments that have not been used for a long time, use a sealed bag (that is, a plastic bag with a column rail at the mouth of the bag) to squeeze out the air, then press the column rail and put it away, so as to minimize the contact between the silver ornaments and the air.
