Gold jewelry with rich traditional Chinese style has always been a favorite jewelry for the people of the country. People who often wear gold jewelry will find that after wearing gold jewelry for a period of time, the surface of the jewelry will appear discolored or faded.
Many people think that this is because of the lack of gold color. If the quality inspection center is checked but it is not the quality of gold, then why will gold jewelry fade?
The fading of our common gold jewelry is only the appearance of white spots or whitish on the surface of gold. In fact, the main cause of these white spots is that gold reacts with mercury.
When gold encounters mercury, a chemical reaction called amalgam is produced, which produces a new chemical, gold amalgam, and the color of gold amalgam is yellow-white, which is adsorbed on the surface of gold jewelry, just like gold fades. Or it produces white spots.
Therefore, as long as you minimize the contact between gold and mercury, you can prevent this from happening.
In life, the cosmetics we often use may contain mercury. If the skin is worn on the skin of the gold jewelry, it will definitely provide a good opportunity for the most fearful gold jewelry and cosmetics containing mercury. The results can also be imagined.
And the thermometers commonly used in life also contain mercury (both mercury), so try not to expose her to mercury or phosphors when wearing gold jewelry.
If your jewelry has white spots, remember not to use a knife or other hard object to remove it directly. The correct method should be to burn the white or white spots with an alcohol lamp or a welding torch. After cleaning with a fine velvet cloth, you can restore the original golden luster of gold.
If there is no alcohol lamp in your home or you don't have enough experience, it is best to send the jewelry to the jewelry store for treatment. Try to avoid using your own lighter. Because the burning is not complete, the jewelry will turn black easily.
On the other hand, “gold is not redâ€, 100% pure gold does not exist. Although the chemical nature of gold is stable, the impurities in gold jewelry react with other chemicals in life, which may also lead to gold jewelry. The surface is discolored or discolored.
Like gold jewelry in the summer, the body's sweat is easy to get on the jewelry, 99% of the human sweat is water, and about 1% is the body's waste and harmful substances, such as chlorine, lactic acid, urea ammonia, etc. After reacting with copper, silver and other substances contained in gold, copper sulfide and silver chloride are produced, and a deep black chemical salt is present on the surface of the gold jewelry, which is why gold jewelry may wear for a long time. The reason for getting black.
Wear gold jewelry in the summer, be sure to always take off the cleaning, and do not bring gold jewelry often into places with serious chemical pollution.
