What causes silver bracelets to turn yellow, and what is the reason for silver bracelets to turn yel

1.Human endocrine and physique: Sweat contains a lot of acid, and some people sweat with high sulfur content.

This substance can easily turn the surface of silver bracelets yellow. So the yellowing of the silver bracelet may be caused by excessive sweating. Generally, silver bracelets turn yellow easily in the hot summer.

2.Touching other substances: Substances such as skin care products, skin care products, and eau de toilettes used by women are silver bracelets with etching effects.

Over time, the surface of the silver bracelet turns yellow and black. Therefore, it is important to note that when wearing a silver bracelet, there is no need to touch anything that contains compounds to prevent damage to the surface of the bracelet. 3.

Poor storage: Some people find that the surface of their silver bracelets that they don't wear often is yellow, which is caused by poor storage. Therefore, if you do not wear silver jewelry, you should pay attention to the independent sealing of the jewelry packaging bag, which is isolated from the gas and is not easy to be oxidized.

In daily life, silver bracelets should avoid contact with water.

Silver is an unstable element, easy to chemically react with sulfur, human sweat contains a lot of sulfur, and silver jewelry contact, it will be used, silver ions and sulfur ions have a great affinity, easy to produce chemical reactions, the result of the reaction is that silver sulfide is produced on the surface of silver, because silver sulfide is gray and black, so with the increase of silver sulfide, the surface color will gradually change from white to yellow to gray and finally black. This chemical change can occur in very small amounts, and silver can occur when it encounters a few trillions to tens of trillions of parts per trillion of hydrogen sulfide or sulfur ions in the air. Moreover, if people are in some polluted environments, when there are more acidic gases, hydrogen sulfide, nitric oxide and other compounds in the air, they will also change color.

What is the real reason why silver bracelets turn black and yellow? Insiders tell you the truth.

Silver bracelets are yellowed for the following reasons:

1. The silver ions contained in silverware have a bactericidal effect, but the silver jewelry worn outside the body does not have such a great effect on the human body. Silver is an unstable element that is susceptible to chemical reactions with sulfur, resulting in discoloration.

2. Human sweat contains a lot of sulfur, which will work when it comes into contact with silver. Moreover, if people are in some polluted environments, when there are more acidic gases, hydrogen sulfide, nitric oxide and other compounds in the air, it will also cause silver jewelry to turn black.

3. The silver bracelet turns yellow, or it may be that the silver jewelry contains antimony or arsenic, which will turn brick red when it reacts with sulfur, which indicates that the composition of the silver jewelry is seriously impure.

Main Effects:

Silver has an attractive white luster, high chemical stability and collection and ornamental value, and is favored by people (especially women), so it is known as a woman's metal, and is widely used as jewelry, ornaments, silverware, tableware, congratulatory gifts, medals and commemorative coins. Silver jewellery has a vast market in developing countries, and silver food is popular with families.

Silver commemorative coins are beautifully designed, have a small mintage, and have the function of maintaining and increasing value, which is highly sought after by coin collectors and coin investors. In the 90s of the 20th century, the silver used for coinage alone remained around 1000 1500 tons per year.

Answer: The reason why silver bracelets turn yellow is usually caused by oxidation. Therefore, in daily life, try to minimize the contact between sterling silver bracelets and water. Yellowed silver bracelets can be obtained, and jewelry stores use silver washing water to clean them.

You can also simply use toothpaste at home to clean the yellowing of the sterling silver bracelet.

It may be that the environment is very polluted, and the air contains something corrosive to silver, you can use toothpaste to rub it on the bracelet with a soft cloth for a while, and the light will be restored.

It's going to be like that! You boil a pot of boiling water! Put a layer of tin and platinum foil in it! If you put the silver jewelry in and cook it for a few seconds before you take it out, you will be amazed.

It should be the reason why the place is polluted and the air is not good, or it may be that you are not accustomed to the water and soil during that time, and it is natural to return home.

You can squeeze some toothpaste and find a soft brush to clean it.

1. The reason why the silver bracelet turns yellow: because the silver bracelet contains silver elements, but silver is an unstable element and is prone to chemical reaction with sulfur. Human sweat contains a lot of sulfur, and when it comes into contact with silver, a chemical reaction will occur.

2. Professional silver polishing cloth: It is a special professional cloth, and then there will be silver powder on it, so that it can be wiped clean.

3. Silver washing water: For silver washing water, you can use the soaking method (except for the old process) or the wiping method (except for the platinum plating process and inlay process), put the silver jewelry into the silver washing water for about three minutes (the oxidation is particularly serious can be put for a long time), take it out and rub it repeatedly, wash it with a large amount of water, put it into alkaline sleep (such as washing powder water) and wash it, and finally rinse it with water.

4. Toothpaste: Use toothpaste to wipe the toothpaste directly on the silver, add a little water to frustrate the foam, and brush it with a toothbrush if there is a seam to avoid the foam from entering the seam.

The silver bracelet turns yellow because the silver has oxidized, which is why it turns yellow. Silver jewelry is very susceptible to oxidation, and the oxidation reaction of sterling silver bracelets under chemical action will make sterling silver bracelets yellow or black. However, these are actually the conditions on the surface of the sterling silver bracelet, and the inside of the sterling silver bracelet is still the same as the original, and there is not much oxidation reaction.

What is the reason for the yellowing of the silver bracelet, this yellowing may be dirty, you can take that toothpaste and wash it.

What causes silver bracelets to turn yellow? The yellowing of the silver bracelet is oxidized.
