5 thoughts on “Why does the gold be darkened over a long time? (The answer must be detailed)”

First of all, we have to formally "fade" in gold. The reason why gold is preserved is because it is "bad". The real gold that we usually encounter is "oxidation" because it encounters a certain liquid phenomenon that will fade and be gloss. In the first case, gold will fade in the face of the human body. In addition to water, the human sweat is also salty. It will produce a subtle chemical reaction when it encounters a gold bracelet. After a period of time, it will fade. The second point is that girls often use some cosmetics, and the substances contained in these cosmetics can also cause gold to fade. The chemicals contained in the third dishwasher will change the gloss of the gold, so try not to wash the dishes as much as possible when wearing a gold bracelet.
The material in life will cause the jewelry to fade in this situation. Let's teach you two tricks. The gold bracelets can be easily lightened without spending money. The first trick is toothpaste. Do not underestimate the existence of toothpaste in ordinary life. Toothpaste not only has a good cleaning of teeth on weekdays, but also has good effects in other places. We use a container, put some water, put an appropriate amount of toothpaste, and stir. Remember who do not put too much, then wipe the gold bracelet with a clean cloth. Doing this in daily life can be as bright as new.
The second trick is to use thick rice soup. Wipe your gold bracelet with this natural clean power will make the bracelets colorful. And when this thing is usually washing the dishes at home, Tao Yiti rice is left, leaving part of it to wipe your gold bracelet or other accessories. It will be more shiny! The following is more common sense. The first small point of gold is actually relatively soft. When wearing it, avoid excessive force when wearing, and it is not good to excessively pull. When the second little point is usually used, you should avoid some occasions, such as not wearing when swimming in the sea. It is better to produce chemical changes in the surface layer. The third little point is that when you do n’t wear it, you should use a velvet to avoid friction.
The turning black or fading of gold jewelry is closely related to the human sweat. 99%of human sweats are water, and about 1%are waste and harmful substances in the human body, such as chlorine substitutes, lactic acid, urea ammonia, etc. After the silver and copper in gold jewelry are in contact with, chemical reactions will be generated, silver chloride and copper sulfide, and dark black chemical salt. This kind of chemical salt is often dropped from gold jewelry to pollute the skin of the wearer, leaving a very obvious black stain on the skin. There are many types and brands of cosmetics nowadays. Many cosmetics or hair dyes contain trace lead elements. Gold encounters lead and it is easy to turn black. Therefore, it is best not to wear gold jewelry when using cosmetics or hair dyeing. In addition, the connection between some gold necklace ring and ring is easy to turn black. This is because the ring -to -phase link of the necklace needs to be welded, and welding is required during welding. Some welding medicines are not high, so that after a period of use of the necklace, it is easy to turn black after sweating in the summer.
There is golden elements in gold jewelry. When gold encounters mercury, it will become "golden mercury with gold" color and become our common white. There is absolutely no mercury in our own body, and these mercury is hidden in the cosmetics we usually use. Most of the cosmetics have trace mercury, and when the gold jewelry wearing accidentally contacts when it is touched, it will become white. In addition to becoming white and black, gold jewelry will also turn black. The hair dye we usually use contains a small amount of lead elements. When the metallic attribute encounters lead elements, the jewelry will turn black. If due to cosmetics and hair dyes, it can be black and white, and gasoline for processing jewelry can be used for heating treatment. The melting point of lead and mercury is relatively low.
Because gold jewelry contains gold, when gold encounters mercury (mercury), it will reflect each other to generate a "gold -mercury agent", that is, it becomes "gold -mercury alloy". The color of this alloy is white. There are many types and brands of cosmetics nowadays. Some cosmetics contain trace mercury. It contains trace lead in using cosmetics or hair dyes. For the above two gold jewelry that has become white and black, it can be eliminated with gasoline spray guns for jewelry processing. Because the melting point of mercury and lead is very low, it will volatilize during the heating of the spray gun, so that the gold jewelry will restore the original face. Of course, it is best to wear gold jewelry when using cosmetics or hair dyeing to avoid posterior trouble.
