Silver jewelry is now available everywhere in the market. Its price is not expensive. All kinds of silver jewelry are favored by female friends. However, silver jewelry has long been blackened. Why is this? Today, Xiaobian compiled some information, for some of the small knowledge of popular science jewelry, don't miss it!
Silver, is a very special metal, very soft and inclusive, can be set with any jewelry. Like its silver white can match clothes of various colors.
"Compendium of Materia Medica" claims that silver has the effect of "an five internal organs, a calming heart, a cure for convulsions, a strong bone, a heart, and a clear eye." Since ancient times, China has favored silver jewelry and silver products. It can be seen that people are wearing silver jewelry. It is not only a simple and beautiful jewelry, but also can bring some benefits to the body.
Why does silver turn black?
First, because each person's endocrine and physical condition are different, some people's sweat contains more acid, some people are less, and some people have higher sulfur content in body fluids, these are substances that cause the surface of the silverware to become black, so Everyone wearing silver jewelry will produce different results, and some people will be as bright as new for half a year.
Second, sulfur, nitric acid and oxides in air and other substances (such as eggs and cosmetics) have a certain corrosive effect on silver. Silver jewellery is worn for a long time. When sulphur and silver are combined, a black silver sulfide film is formed on the surface of the silver jewellery. It begins to appear as tiny spots, which then diffuse into pieces, forming what is commonly called silver scale. It becomes black and affects the surface gloss of silver jewelry. People often mistake it for color.
Because of these natural characteristics of silver, silver has a good health care function, and often wears toxic substances that can neutralize the human body. Silver ions have a strong bactericidal effect, can eliminate 650 kinds of pathogens, can be used as a test tool, which is very beneficial to the human body. It can also accelerate wound healing, prevent infection, and have the effect of purifying water and preserving and keeping fresh. The ancients said: wearing silver, healthy and wealthy will accompany you, and the five internal organs, calm the mind, stop the horror, in addition to evil. In medicine, it is much more effective than other precious metals for human health.
Blackened solution
If the silver jewelry turns black, don't rush to wash it with silver. Because silver water is a chemical, it also has a certain corrosive effect on the jewelry. Silver cloth is your first choice. There are also many small recipes, such as putting a silver jewelry in a cola for a night, or brushing it with a soft brush. But after washing, remember to dry the water with a cotton cloth.
Silverware cleaning and maintenance method
Many people like silver, but they don't know much about the maintenance of silver. Some people think that silver is difficult to maintain. This is not the case. After learning why silverware is getting dark, we only need to spend a little time in our daily life, so that the silverware we wear can last forever.
1. When the silverware is not worn, it should be cleaned and then collected. It is best to use a closed pocket to prevent oxidation and blackening. If the wearer has more sweat, he can wipe the surface with a soft cloth every day to maintain the luster and remove dirt. It is best to use a special silver cloth for the silver plating of the surface, and the silver cloth can be purchased at the silver brand store. Note: The silver cloth contains maintenance ingredients and cannot be washed.
2, silver plating without electroplating, daily cleaning can be done by yourself, such as squeezed toothpaste, add some water, wash with a soft cloth, the gap can be brushed with a soft soft toothbrush, then rinse with water. (Gemstones with gemstones should not be stained with water to prevent the water from affecting the firmness of the glue. It is best to be cleaned by specialists in the store)
3, the variety of silver crafts, maintenance methods are also different, can not be generalized, many online maintenance methods can only be used as a reference, it is best to ask the store professionals, in order to avoid their own improper operation, resulting in the beloved silver jewelry damage.
4, with exquisite and three-dimensional sculpture made of silver, to avoid deliberately wiping the light. If you find signs of yellowing in the silver, you should first clean the cracks of the silver jewelry with a small brush, then wipe the surface with a silver cloth to restore the original silver and light. I suggest you: If you can use silver cloth to restore about 80% of the silver condition, you don't need to use silver milk and silver washing water. Because these products are corrosive, silver products will become more and more after using these products. Easy to turn yellow. The silver cloth contains silver maintenance ingredients and cannot be washed.
5. If the silverware is not processed and stored after being worn, it is very likely that the silverware will be blackened. At this time, you should use a small jewelry brush to clean the fine seams of the jewelry, then drop a silver drop of the silver cream on the paper, wipe off the black oxide on the silver surface, and then use the silver cloth to restore the original brightness of the jewelry. After that, remember to do the daily general maintenance, to avoid the silverware blackening again, the silver ornaments are difficult to whiten after many times of blackening.
Benefits of wearing silver jewelry:
Benefit one: sterilization
The silver ions contained in the silver jewelry have a strong bactericidal effect and can kill 650 kinds of bacteria. It is to be understood that the general antibiotics only act on the pathogens of the six bacteria, thereby showing how strong the bactericidal effect of the silver jewelry is.
Benefit 2: Drug abuse
Many people will wonder why silver jewelry will slowly turn black after wearing it for a long time. In fact, this is because silver reacts with many toxins to make the silver jewelry black. We have all seen the use of silver chopsticks to measure poison on TV. The principle is the same. While helping to absorb human toxins, it is also possible to judge the health of the human body based on this.
Benefit three: heat transfer
Silver has excellent thermal conductivity. It wears silver jewelry for a long time, and it can dissipate excess heat in blood vessels, which is a miracle to prevent various diseases.
