Gold jewelry is not necessarily because of the purchase of fakes.
After wearing gold jewelry for a period of time, people found discoloration or fading. Many people thought that this was a lack of color in gold jewelry. So the store negotiated or went to the Consumer Association to complain, but it was told that the jewel of gold jewelry was not the color of gold jewelry. Insufficient, but other reasons, then, what are the reasons? In the end, gold jewelry and anything will fade?
Gold jewelry and anything will fade? Xiao Bian feels that the phenomenon of discoloration or fading of gold jewelry does not mean that the color of gold jewelry is insufficient, but it is closely related to the sweat of the human body.
Gold jewelry and something will fade
(1) Do not touch with substances containing acid or alkali, otherwise the gold jewelry will be discolored and dim.
(2) Do not touch with oily daily necessities, cosmetics containing mercury or lead, or daily necessities, otherwise the gold jewelry will be dim or white.
(3) Do not touch or rub with metal substances such as platinum, palladium, silver, lead, aluminum, tin, mercury (mercury), or the contact point will become white.
Beware of the damage of sweat and cosmetics to gold ornaments
It is well known that some of the sweat is a waste and harmful substances in the human body. When these materials come into contact with silver and copper in gold jewelry, they will chemically react to produce silver chloride and copper sulfide, which will cause discoloration or fading of the jewelry.
When silver and copper in gold jewellery come into contact, a chemical reaction occurs, producing silver chloride and copper sulphide, and exhibiting a deep black chemical salt. This chemical salt often falls from the gold jewelry, contaminating the wearer's skin, leaving a very noticeable black stain on the skin.
At present, cosmetics have become one of the "characters" indispensable to people's lives. If it is applied to the skin of the gold jewelry wearing part, then it will undoubtedly provide opportunities for cosmetics containing chemical substances and gold jewelry that is most afraid of chemical attack, and the result can be imagined.
Some cosmetics also contain some fine hard particles, which can form another type of dirt, thus consuming gold jewelry. Regional environmental factors may also cause gold jewelry to lose its bright color. For example, in a dry area, the air contains more original fine dust, which will form a kind of “human body sandpaper†when it is contaminated with the human body. It can rub the gold jewelry into extremely fine debris and appear partial black stains. It is worth mentioning that the talcum powder or moisturizer also contains similar particles, which will also eclipse the gold jewelry as mentioned above.
