Any metal is exposed in the air, and a chemical reaction will be generated with the oxygen in the air. The final result is to form a layer of oxide on the metal surface. If found that wearing gold jewelry and just buying time, it is actually caused by the oxidation reaction of the long time, which is the so -called "rust". Gold rust is not obviously because gold has strong anaerobicity. From the perspective of metal activity, gold is ranked last. As a result, gold can be maintained for a long time, which is one of the reasons for people's use of gold as jewelry materials.
Gold jewelry is something that many women like to wear, but many people find that the gold will gradually become dark and darkened after the gold is worn for a long time. So what causes gold to change such a change?
The first is cosmetics. Gold will react with some substances in cosmetics, but many women will ignore this when wearing gold jewelry, so that gold is exposed to cosmetics and reacts.
It is sweat. Our skin surface will excrete a little sweat every day, especially in summer. These sweat contain some waste in our body. They will also cause gold to become black after contact with gold.
First of all, because of contact with the human body, the various types of elements contained in human sweat will have a chemical reaction with the silver and copper in gold products. Most of these generated substances are silver chloride and copper sulfide. The colors they present are black , That is, people think that gold is rusty. The second is that people often use cosmetics. If cosmetics contain the mercury components that increase the white function, white spots will occur after contact with the contact. Whether it is rust or white spots, consumers can go to the designated after -sales venue to clean or eliminate it.

There are many uncommon erythema on gold, but this is not caused by purity. On the one hand, it is due to improper preservation. On the other hand, it may also be metal or chemical residues during production. There are quality problems or insufficient quality problems.
