Why does silver rub the body black, and what happens when the silver scrapes the body skin and turns

That's because the silver oxidizes and turns black.

The secretions produced by the body contain sulfur, which causes a reaction with silver, which turns ** black.

The secretion of the human body has a maintenance effect on silver jewelry, most of them are worn more and more brightly, only a few people, because of personal physique, the more they wear the darker, not necessarily not in good health. When silver hits sulfur, it turns black, which can be proved by rubbing silver products with boiled egg yolks with more sulfur content. Some people have more sulfur in their sweat, and silverware is easy to turn black, so it is not suitable to wear silverware with this kind of physique.

Blackened silverware can be wiped off with toothpaste applied to a cloth.

It will turn black when it encounters sulfides, sulfur oxides, chlorides, nitrogen dioxide, and oxygen in the air.

Silver jewelry blackening is a normal natural phenomenon, because the air and other natural media in the sulfur and oxides have a certain corrosive effect on silver, after wearing for a period of time, there will be some tiny spots (silver sulfide film), over time will spread into a piece, or even turn black. Therefore, at present, silver jewelry has some discoloration due to oxidation. Here are a few suggestions:

First of all, we should strengthen the knowledge of maintenance: Most consumers know that silver will turn black, but they don't know how to prevent it from turning black or what to do This is the root knot of some consumers' reluctance to buy silver jewelry. Therefore, teaching how to maintain and remove oxides on the surface of silver jewelry and restore the luster of silver jewelry is a guarantee of consumer confidence.

The main ones are to do the following:

Do not wear other *** jewelry at the same time when wearing silver jewelry to avoid collision deformation or abrasion.

Avoid contact with water vapor and chemicals, and avoid swimming while wearing them, especially when going out into the sea.

After wearing it every day, wipe it clean with a cotton cloth and put it in a jewelry box or bag to seal and store.

It has been oxidized and blackened, and it can be cleaned with a soft-bristled brush dipped in toothpaste, or by hand rubbing soap or detergent. If you can't clean it, scrub it with silver water, and wipe it dry with a cotton cloth after washing.

The principle of ancient people using silver needles to check whether food is poisonous is that silver encounters sulfide will produce black silver sulfide precipitates, and most of the ancient poisons contain sulfur, so silver needles can be detected.

Take stock of the reasons why silver turns black.

1. When the silver is left for a long time, the metallic silver on the surface of the silver is in contact with the oxygen in the air and slowly oxidizes to silver oxide, so it turns black.

2. When the silver touches the acid, alkali or salt, it accelerates the oxidation to become silver oxide.

3. Silver jewelry generally worn on the hand, because of the effect of salt in sweat, accelerates oxidation and blackening.

Benefits of wearing silver:

Silver ions have a strong bactericidal effect.

Silver contains silver ions, which have a strong bactericidal effect and are very beneficial to the human body. In addition, the thermal conductivity of silver is the most prominent of all metals, and it can quickly dissipate heat from blood vessels.

This distinct heat conduction property quickly reduces the heat of the blood vessels, and has excellent efficacy in preventing various diseases.

Silver also has the function of absorbing toxicity.

Silver also has the function of absorbing toxicity, which is one of the reasons for its discoloration, so it has excellent disinfection properties, and this discoloration is only a surface reaction, which can be eliminated with toothpaste or medicine.

Silver has a good health care effect.

Regular wearing of silver jewelry can not only neutralize toxic substances in the human body, but also accelerate wound healing, prevent and treat infections, and has the effect of purifying water quality and preserving freshness. Mongolian herders like to use silverware to hold fresh milk. Modern science has proved that silver contains fresh milk, and it does have scientific roots.

Oxygen in the air. It will be black. And carbon dioxide. Oxide of sulfur. It will be black.

The blackening of the silver is not a bad health.

The chemical properties of silver are relatively stable and the corrosion resistance is relatively strong, but the sulfur nitric acid and oxides in air and other natural media have a certain corrosive effect on silver. After wearing the silver head for a long time, a layer of black silver sulfide may be formed on the surface, because silver sulfide is gray-black, so with the intensification of the reaction, the vulcanization increases and thickens, and the surface color gradually changes from white to yellow to gray, and finally to black.

There may be a variety of other reasons for the blackening of silver jewelry, such as sweating, perennial smoking, the habit of spraying perfume and heavy makeup, often using sulfur soap, and liking hot springs, etc., which may cause silver to turn black. The more you wear silver, the darker it becomes, and the quality of your body has nothing to do with it, and the claim that wearing silver jewelry can absorb toxins in the body is also unscientific.

Silver bracelet cleaning tips

Silver bracelets can also be cleaned with white vinegar to brighten, dilute the white vinegar with a small amount of water, and soak the silver bracelet that needs to be cleaned directly into the white vinegar for a period of time.

Silver bracelets can also be cleaned with tea, after soaking the silver bracelet that needs to be cleaned in tea for a period of time, the oxides, dust and other dirt on the surface of the silver bracelet will gradually fall off, and finally you can rinse the bracelet with clean water and wipe off the water on the surface. Silver bracelets can be washed with tin foil, first wrap the inner wall of the container with tin foil, then add salt water to it, put the silver bracelet in the tin foil, heat it with fire, and heat it until the silver bracelet is completely bright.

Is it bad health for silver to turn black? Some people wear silver bracelets and turn black after a short time, why does this happen? Does it indicate something wrong with the body? Let's take a look.

1. Is it bad health for silver to turn black?

It is a very normal phenomenon that silver turns black and has nothing to do with the body, and the folk rumor that silver turns black because of bad health is wrong and has not been verified. As we all know, the air contains nitric oxide, hydrogen sulfide and other substances, and these oxides have a certain corrosive effect on the silver jewelry itself.

In the daily wear of silver jewelry, pay more attention to the following points to avoid the blackening of silver jewelry:

1. Avoid silver encountering water. During swimming, bathing, washing clothes, etc., silver jewelry should be removed, which can slow down the process of oxidation.

2. Avoid sweating. When wearing silver jewelry in summer, due to the high temperature of the weather, people who are outdoors are easy to sweat, and sweat is easy to cause discoloration of silver jewelry, so you can pay attention to it when wearing it.

3. Avoid beauty products. If silver jewelry collides with skin care products such as jewelry or perfume, it is also easier to cause discoloration of silver due to the complexity of chemicals.

Second, the blackening of the silver bracelet is a physical illness

Human sweat contains sulfur, ammonia, etc., and the air will also contain hydrogen sulfide, nitric oxide and other substances, which will cause the surface of silver jewelry to be oxidized, and then discolored, lose luster. "The blackening of silver jewelry is also related to the acidity and alkalinity of human sweat, sweat is acidic, and the speed of silver jewelry blackening will be faster. Secretary-General Wang said that the seams of silver jewelry are less in contact with **, clothing, etc., and are more likely to be oxidized and turn black first.

Blackened silver jewelry can be cleaned with toothpaste and cotton swabs. Go to a regular store to buy silver jewelry. Some unqualified silver jewelry lead, mercury and other harmful substances exceed the standard, and long-term wear is harmful to the human body.

It is easy to turn black when wearing silver jewelry, which is normal and has nothing to do with body poisoning.

3. The silver bracelet turns black

Silver is an active metal, easy to react with sulfur in the air, making silver black, so try not to wear it in a place where the chemical gas is thick, and it must be dried immediately after contacting sulfur soap.

Chloride in sweat also has an effect on silver. Silver and gold should not be worn at the same time, which will cause the silver to turn yellow. Of course, after a long time, whether it is plated or not, silver jewelry will still oxidize and change color.

Daily cleaning: Use a professional silver cloth.

Next, let's talk about other methods, which may not be so easy and convenient in our lives. First of all, we buy professional silver polishing paper to wipe. What is professional silver polishing paper, it is a special professional cloth, and then there will be silver powder on it, so that it can be wiped clean.

No, whether silver becomes light or black is not necessarily related to whether it is healthy or not.

The reason why silver jewelry turns black is because of the oxidation reaction, and the oxidation of silver jewelry is unavoidable. When wearing silver jewelry, human sweat contains sulfur, ammonia, etc., and the air will also contain hydrogen sulfide, nitric oxide and other substances, which will cause the surface of silver jewelry to be oxidized, and then discolored, lose its luster.

The blackening of silver jewelry is also related to the acidity and alkalinity of human sweat, sweat is acidic, and the speed of silver jewelry blackening will be faster, which has nothing to do with whether it is healthy or not.
