I bought a pure silver bracelet and put it in the box for half a month without it, why did I have da

I opened a silver shop, and the silver bracelet will only be black if you don't wear it for a long time, and if it is really oxidized, then the silver cloth will be bright. Pure silver is easy to oxidize, and it will turn black after wearing it for a while, even if it is placed in a box. But the more silver jewelry there is, the more spirituality it is.

It is recommended that the cuties wear it often, which can detoxify.

Copper added to silver. This alloy containing silver and copper is internationally known as standard silver. Also known as sterling in the UK.

In addition, there are pure silver jewelry with a silver content of 99 on the market. 925 silver is the international standard silver for making silver jewelry. It is different from silver because the purity of silver is relatively high, and it is very soft and difficult to make complex and diverse jewelry, while 925 silver can do it.

925 silver jewelry is not actually 100% silver, that is because the alloy added to the sterling silver has improved the luster, brightness and hardness of the silver. Silver can change color and even dissolve when exposed to any acid. If a drop of concentrated hydrochloric acid is placed on the inside of the silver jewelry, a white moss-like silver chloride precipitate is immediately formed.

This is not the case with other ***.

After the silver encounters sweat, it will oxidize and turn black for a period of time, just take a cloth dipped in some toothpaste and wipe it, and wipe it off next time you take it off and then put it up.

The surface of the silver is oxidized, and the oxidized silver is black. It is recommended to keep it in a dry place.

If it is oxidized, it can be wiped with a silver cloth.

Or wash it off with some toothpaste!

Silver is like that, as long as you carry it for a while, it will shine again.

If silver jewelry is not sealed or regularly maintained, it will quickly darken in color. The best way to keep your silver jewelry is to wear it every day.

Reasons why silver jewelry turns black:

1. Silver jewelry may form a layer of black silver sulfide on the surface of silver jewelry after wearing it for a long time. Sweat contains more sulfur, so with the intensification of the reaction, the silver sulfide increases and thickens, and the surface color gradually changes from white to yellow to gray and finally to black.

2. Silver can also react with oxygen in the air to form brown-black silver oxide. Under high temperature conditions, the oxidation reaction rate is faster, and the oxidation rate at room temperature is slower.

3. If there are many acidic gases, hydrogen sulfide, nitric oxide and other compounds in the environment, silver jewelry will react with these gases, causing silver jewelry to turn black.

4. Under normal circumstances, the surface of the silver will be oxidized, and the color will become dull and shiny.

The surface is oxidized, go to the jewelry store and wash it.

The surface is oxidized, just buy a silver cloth to wipe it.

1. Blackening due to oxidation. When there are many compounds such as acid gas, hydrogen sulfide, and nitric oxide in the air, it will cause the silver to turn black.

Second, everyone is in a different environment, so it is normal for the luster of silver jewelry to be different. Some people have more acid in their sweat, others have less, and these are the substances that cause the surface of silver jewelry to darken.

3. Everyone is exposed to different corrosive substances, such as sulfur, nitric acid and oxides (in eggs and cosmetics) have a certain corrosive effect on silver. The combination of silver jewelry and sulfur will form a black silver sulfide film on the surface of silver jewelry, which will affect the surface luster of silver jewelry, and people usually mistakenly think that it is fading.

Silver bracelets are not oxidized because they are worn, and silver bracelets do not turn black because they are not stored properly, in a strong oxidizing environment, or contaminated with strong oxides, they will cause oxidation on the surface of silver bracelets, which is the reason why silver bracelets turn black. Therefore, it is best to put it away when not wearing it, and it is best to pack it in a closed pocket to prevent the surface of the silver jewelry from oxidizing and blackening in contact with the air. This blackening is a normal oxidation phenomenon, and the bracelet should be cleaned correctly, generally by wiping it with a silver cloth, or sending it to a professional silver jewelry store for treatment.

Silver bracelets can be blackened by toothpaste cleaning, silver washing liquid cleaning to remove black spots, toothpaste is a good helper for silverware blackening. Toothpaste is rich in fine calcium carbonate particles that rub against the surface to wipe away silver oxides. Find a toothbrush, dip a little toothpaste and rub it patiently and vigorously for a while, then wash it with water.

There are silver cloths and silver washing liquids on the market, which can quickly erase or wash off the black surface of silver bracelets. When I went to a silver bracelet shop and asked someone to help me scrub it, I mostly used these two things. Silver bracelets should not be scrubbed with these things as they are corrosive and can cause silver bracelets to turn black more easily.

It may be that the oxidation has come into contact with sulfur-containing substances, silver oxides and sulfides are black, and if you go to the store where you bought it, you can use toothpaste or stain removal powder to remove it.

Silver jewelry, the higher the purity, the more likely it is to produce oxidation reactions, improper storage, such as humid environments, especially in southern cities, is more likely to oxidize and blacken, although it will be much slower than normal wear.

If you can guarantee that it is sterling silver, then it is oxidized (oxidized and blackened). If this is not guaranteed, it is due to oxidation of silver and lead.

It's okay if it's oxidized, just bring more belts.

In this case, it should be oxidized, you can just rub it with a cloth and a little ointment.

Summary. Hello dear ! It's not fake, it's a normal phenomenon to buy a special silver cloth, a few dollars is enough, you can also wipe it with toothpaste, this is a relatively simple way Toothpaste The easiest way is to use toothpaste to squeeze on the silver jewelry, wipe it, and after a while, the silver jewelry will be as natural as new [Silver Jewelry Maintenance Tips] Silver jewelry is easy to blacken after wearing it for a long time, which is a normal phenomenon, you can soak it in ammonia and baking soda or wipe it with toothpaste, and then wash it with water and wipe it dry to restore its luster.

But when I bought it back, I wore it yellow halfway, and the yellow one was wiped off, and the black spot couldn't be wiped off, and more than 200 yuan was bought in Dewu.

Just like this, the color inside the circle that can't be photographed is like copper.

Hello dear ! If the bracelet is impure silver, it may contain other metals or impurities that may cause black spots to appear on the surface of the bracelet. In this situation, it is necessary to buy regular brand silver products.

In general, if you buy a silver bracelet with black spots on the surface, you need to first determine the cause of these black spots and then take the corresponding cleaning method. If you can't determine the cause of the black spots, it's best to find a merchant.

Good hook up. If you really don't feel at ease, you can go to the place where you buy the silver to supervise, if it is fake, you can ask the merchant to exchange it for the real one.

Hello, I am helping you to inquire about the relevant case and will reply to you immediately.

I just bought it back, and after a day, there are black spots, is it fake.

It should be true.

Because silver when exposed to air will have a pro oxidation reaction.

will turn black. The real thing will be black, so it won't be fake.

It's dark, wipe it with a wet towel and see if it works.

Look at it. Is it true.

I can't see it.

Your color, it looks real.

Hmmm, okay. Have a great day.

Summary. The reason why some silver bracelets will be black and some will not mainly depend on the following factors:1

Purity of silver: Silver bracelets with higher purity are usually less susceptible to oxidation and blackening. Generally speaking, the higher the purity of silver jewelry, the less likely it is to turn black.

2.Airborne Chemicals: Silver reacts with sulfides, oxides, and chemicals in the air, causing the surface to gradually darken.

Different regions have different air quality and chemical environments, which can also cause different degrees of black variation on the surface of silver bracelets. 3.Personal physique and living habits:

Factors such as an individual's pH value, perspiration and daily contact with objects can also affect the blackening of silver bracelets. For example, some people with a higher pH level in the body are more likely to make silver jewelry black after oxidation. 4.

Storage and maintenance: Proper storage and care are important for the maintenance of silver bracelets. Keeping silver jewelry dry and avoiding exposure to chemicals and moisture can slow down the rate at which silver jewelry turns black.

It is important to note that in some cases, the blackening of silver bracelets may be due to the formation of a layer of silver sulfide on the surface, in which case only a professional cleaner is needed to restore the luster of the silver jewelry.

Fellow, I really didn't understand, I can be more specific.

The blackening of a silver bracelet depends on several factors: the purity of the silver, the chemicals in the air, the individual's constitution and lifestyle habits, as well as the way they are stored and maintained. High-purity silver bracelets are generally less prone to blackening.

The air quality and chemical environment in different regions can also cause different degrees of darkening. The pH value, perspiration and daily contact with objects will also affect the degree of blackening. Proper storage and balancing can slow down the rate of darkening.

If it is a darkening caused by silver sulfide, you can use a professional cleaner to restore the shine.
