How did the silver bracelet turn black, what is the reason why the silver bracelet turned black

There is such a sentence "wearing gold is not as good as wearing silver" Many people prefer to wear silver jewelry, silver jewelry ** is more close to the people, and there are many styles, so it has been loved by young people, but silver jewelry will become black after wearing it for a long time, so what causes silver jewelry to turn black? In fact, silver and gold are the same, both are a kind of historical ***, archaeologists from the unearthed Spring and Autumn period bronzes found inlaid on the surface of the gold wire and silver wire woven "gold and silver wrong".

In the process of silver jewelry processing, people usually add copper or other metals in order to improve the hardness and obtain the best molding effect, so this kind of silver jewelry is called standard silver in the world, in which the silver content is, which is why it is called 925 sterling silver, and there is also a high purity, that is, 990 sterling silver, so as the name suggests, the silver content is as high as 99%. The reason why silver jewelry will turn black after wearing it for a long time is because silver jewelry will react with hydrogen sulfide in the air when exposed to the air for a long time to produce black silver sulfide, which is the main reason for the blackening of silver jewelry.

So is it that the silver jewelry has become black and can only be put aside? In fact, pay attention to the maintenance of silver jewelry, silver jewelry can also shine as new, the following teach you a few tricks to restore the original brightness of silver jewelry, so that your beloved silver jewelry back to its original appearance.

1. Wipe with toothpaste, wipe the toothpaste directly on the silver jewelry, then add a little water, rub out the foam, and scrub the seamed area with a toothbrush to avoid the foam from entering the seam, so that the silver jewelry becomes extraordinarily clean.

2. Wipe it with cotton dipped in white vinegar, and the black silver sulfide will be dissolved in ester acid, or soaked in overnight tea, so that the silver jewelry can show luster again.

3. There is another method that you may not know, that is, use the correction liquid, apply the correction liquid to the silver jewelry, and then wipe the silver jewelry with a cloth before the correction liquid is dry, which is absolutely effective and very practical.

Summary. Hello dear, I am happy to answer for you, there are reasons why the silver bracelet turns black: 1. Due to the continuous metabolism of the human body, the toxins are also eliminated, and if the body toxin elimination encounters the silver bracelet, the silver bracelet will turn black.

2. When people are in some polluted environments, there are more acidic gases, hydrogen sulfide, nitric oxide and other compounds in the air, which will also cause silver jewelry to turn black. 3. If the silver bracelet is not worn often, it doesn't matter if you take it off, just put it away, and the silver jewelry will also combine with the sulfur dioxide in the air to undergo a natural oxidation reaction and turn black.

3. If the silver bracelet is not worn often, it doesn't matter if you take it off, just put it away, and the silver jewelry will also combine with the sulfur dioxide in the air to undergo a natural oxidation reaction and turn black.

Kissing and maintaining silver bracelets mainly include sealed preservation, avoiding chemicals, less touching water, cleaning, avoiding oil stains, etc., as follows: 1. Sealed preservation, when not worn, it should be sealed and stored to isolate the air to prevent oxidation. 2. Avoid chemicals, avoid contact with detergents, shower gels and other chemicals, so as not to accelerate oxidation and cause blackening.

The first reason is that silver bracelets come into contact with sulfur-containing things, such as the soap we use to wash our hands, the dish soap we use to wash dishes, and even some women's cosmetics. Silver bracelets will slowly turn black if they are exposed to it for a long time, which is a normal chemical reaction.

The second reason: in the summer, some people sweat very easily, while some people have a higher sulfur content in their sweat. Then the silver bracelet worn on the hand is exposed to sweat every day, and it will slowly turn black in no summer.

The main reason is that the silver in the bracelet reacts with the sulfur in the sweat and then turns black. The third reason may be related to the working environment, because some people work in chemical factories and wear silver bracelets that are exposed to the air, because the air in chemical factories will contain chemicals, so the bracelets worn will slowly turn black over time. Is there any way to brighten a blackened bracelet?

When we find that the silver bracelet we wear on our hand is black, there are two small ways to make the bracelet brighten again. The first small method is to use a soft-bristled toothbrush to dip a little toothpaste on the surface of the silver bracelet.

This little method is very practical. Basically, the blackened silver bracelet will gradually brighten after brushing it with toothpaste a few times. The second small method is:

You can buy professional silver cloth, which can be bought online. It is also very convenient to use, just put the cloth on the bracelet and wipe it from side to side. Don't rub it back and forth, because the friction back and forth will rub the pattern of the bracelet, so the bracelet will turn from black to light after wiping it with silver paper.

Daily maintenance of silver bracelets If we take off the bracelet as much as possible when washing dishes, avoid contact with chemicals, and keep the silver bracelet dry, then we should take off the silver bracelet and wipe it with a soft cloth or a professional silver cloth. When it's cold, take off the silver bracelet when you soak in the hot springs, because the water in the hot springs has a high sulfur content.

Summary. Hello dear, silver bracelets will turn black, generally due to oxidation reactions in the air. For example, when a silver bracelet is worn, the acids in the air can form a black oxide product at the contact point with the silver, causing the silver bracelet to turn black.

In addition, the same change may also occur when a person places the bracelet in the chemical environment where hydrogen sulfide is present, and then it turns black.

Can you elaborate on that a little bit more?

In addition, the hand cream and other cosmetics you wear on a daily basis will also have an impact on your bracelets. If you want to restore the silver bracelet, you can use toothpaste and toothbrush to clean it, or you can use tin foil + edible salt + boiling water, soak it in a container, and wash it (if you don't have tin foil, you can use the tin foil shell of the used tablets), I hope mine is helpful to you. 

Summary. 1.Oxidation:

The reaction of silver with oxygen in the air forms an oxide layer, which turns the surface of the silver bracelet black. 2.Dirt on the surface of the bracelet:

Silver bracelets are stained with dust, grease, or other stains that can remain on the surface for a long time, causing the bracelet to darken in color. 3.Chemistry:

If you use cosmetics or perfumes that contain chemicals such as sulfur and nitrogen, it may cause a chemical reaction and cause the bracelet to turn black. 4.Water Quality Issues:

In some areas with hard water, the water contains more calcium and magnesium ions, which will cause scale to appear on the surface of the silver bracelet and form a black substance. 5.The material of the bracelet itself:

Some silver bracelets may contain other materials, such as copper, zinc, etc., which may react with the air and cause the bracelet to turn black.

1.Oxidation Ensemble: Silver reacts with oxygen in the air to form an oxide layer, which turns the surface of the silver bracelet black.

2.Dirt on the surface of the bracelet: Dust, grease, or other stains on silver bracelets can remain on the surface for a long time, causing the bracelet to darken in color.

3.Chemical reactions: If you use cosmetics or perfumes containing chemicals such as sulfur and nitrogen, you may cause a chemical reaction and cause the bracelet to turn black.

4.Water quality problems: In some areas where the water quality is harder, the water contains more calcium, magnesium and other ions, which will cause scale to appear on the surface of the silver bracelet and form a black substance.

5.Problems with the material of the bracelet itself: Some silver bracelets may contain other materials, such as copper, zinc, etc., which may react with the air and make the bracelet darker.

1.Use a professional silver cleaner and operate according to the instructions of the letter change; 2.Soak the silver bracelet in warm water and a small amount of laundry detergent, and gently wipe it with a soft toothbrush or soft cloth; 3.

Apply white vinegar or alcohol to the surface of the silver bracelet and wipe it with a soft finch cloth; 4.Squeeze out a little toothpaste, gently scrub the surface of the silver bracelet with a toothbrush, and rinse it off with water.

Summary. Silver bracelets are easily oxidized. When we come into contact with the air in our daily life, or the cosmetics, skin care products, perfumes and other substances used by women, they will have a corrosive effect on the silver bracelet, and the surface of the silver bracelet will turn black after a long time.

There is also more acid in the sweat of our human body, and the sulfur content in the sweat of some people is relatively high, and the sulfur in the sweat reacts with the silver bracelet, and the silver bracelet is also easy to turn black.

There is also more acid in the sweat of our human body, and the sulfur content in the sweat of some people is relatively high, and the sulfur in the sweat reacts with the silver bracelet, and the silver bracelet is also easy to turn black.

Can you add, I don't quite understand it.

One of the easiest ways to turn a silver bracelet black is to clean it with toothpaste. First, dip the silver bracelet in water, then use a toothbrush with fine and soft bristles, squeeze a little toothpaste (be careful not to use toothpaste with frost particles), gently scrub the surface of the silver jewelry, and dry it with a soft cloth after washing.

There are three reasons why silver bracelets turn black: 1Silver bracelets are easily oxidized when in contact with sulfur substances. In our daily contact with the air, or in the cosmetics, skin care products, perfumes and other substances used by women, there will be some chemicals that have a corrosive effect on silver bracelets.

Over time, the surface of the silver bracelet will turn black. 2.Sweating moreOur sweat contains some sulfur components, especially in summer, the weather is hot, Jingheng will inevitably sweat, after the silver bracelet comes into contact with sweat, silver and sulfur undergo a chemical reaction to generate silver sulfide.

This can also cause the silver bracelet to turn black. 3.The texture of silver bracelets is not pureGenerally speaking, the silver jewelry on the market reaches 999, even if the bracelet is black, it can be cleaned Bi Xiao.

However, if it is a silver bracelet with an impure texture, it will be difficult to clean after the silverware itself is blackened, so there is also a reason for the blackening of the silver bracelet may be the impure texture of the silver bracelet, the silver plating on the surface of the silver bracelet is worn off, and the internal metal is oxidized.
