What will happen if the silver bracelet doesn't change color after buying it? As one of the most important jewels in China traditional culture, bracelets can be used for decoration or as gifts. Bracelets contain beautiful moral and symbolic meanings, so let's see what happens when silver bracelets don't change color when bought.

What happened when I bought the silver bracelet? 1 Reasons for discoloration of silver bracelet.

The important factor is the chemical reaction between silver ions and sulfur ions, and the result of the reaction is the formation of silver sulfide on the surface of silver. Because silver sulfide is grayish black, with the increase of silver sulfide, the color of silver surface gradually changes from white to yellow, then to gray, and finally to black.

This chemical change can occur in a very small amount, as long as silver meets hydrogen sulfide gas or sulfur ions in the air in the range of trillions to hundreds of trillions, this chemical reaction will occur.

Human sweat also contains sulfur, and contact with silver products will make silver discolor, especially the hydrogen sulfide produced by sewage and garbage discharge in urban air is even more amazing, so it is not surprising that silver discolors. Just wash with toothpaste, especially fluoride toothpaste.

Rules for wearing silver jewelry

Identification of silver ornaments

Look at this mark.

Silver ornaments are generally stamped with the English abbreviation of silver ("S" or "Sterling"). The mark of standard silver is S925 or 9.25 or 925. The imprint of foot silver is S990. But there are also many countries that don't print paper money on silver ornaments. Or 9.25925 marks. There are also thousands of silver labels or S999.

Check the color

Silver ornaments are mostly yellowish silvery white with a soft metallic luster. Due to easy oxidation, the color will turn dark yellow and white after a long time.

consider

The density of silver is10.53g/cm3. Smaller than platinum and gold, it won't fall off by hand. Steel needles can be marked or bent. In this way, it can be distinguished from German platinum, K gold or imitation silver jewelry.

Check hardness

The hardness of silver is lower than that of copper, but higher than that of lead and tin, so it can be tested by marking jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry.

Listen to this poem

Sterling silver jewelry fell to the ground and was not elastic. The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of falling to the ground is dull, short and inelastic.

Maintenance of silver ornaments

1, wash clothes and take a bath, and take off the silver ornaments for rough work.

2. Keep the silver ornaments tightly when not in use, and avoid putting them together with hair gel, perfume and skin care products.

3, silver jewelry contact with hot spring water or sulfide, easy to change the surface, so should avoid wearing in hot spring areas.

4. Silver is light brown after oxidation, and can also be directly wiped with a silver cloth.

5, the best way to maintain silver jewelry is to wear it every day, because human body oil can make silverware produce a natural and moist luster, which is the so-called "human body support."

6. Pay special attention to the silver ornaments inlaid with stones, and try not to get wet, because there will be gaps in the mosaic joint, and the stones will easily fall off when they meet water.

Please don't worry if the oxidation turns black. It can be wiped with silver cloth or washed with silver washing water. Note: please rinse with plenty of water after cleaning, and finally rub with a little alkaline water (such as soapy water or washing powder water) for a while, then rinse with clear water and dry with a soft cloth. Finally, the reason why washing powder is used again is to neutralize the weak acidity of silver washing water, so as to really play the role of silver washing water.

What will happen if the silver bracelet doesn't change color after buying it? The reason why the silver bracelet turns black but does not change color is mainly because the surface is easily oxidized with air, thus forming a layer of oxide on the surface, which leads to the surface turning black. At this time, you can scrub it with toothpaste, or soak it in cola, and then rinse it with water.

The silver bracelet has no reason why it will turn black.

Silver bracelet is one of the decorations that many people like to wear. The reason why the silver bracelet will turn black if it is not worn for a long time is mainly because the surface of the silver bracelet is easily oxidized with air under the condition of preservation, and a layer of oxide will be formed on the surface, which will affect the quality and color of the silver bracelet.

When the silver bracelet turns black, it can be scrubbed with toothpaste at this time. The alkaline substances in the toothpaste can neutralize the blackened substances, remove the blackened oxides, and then wash it with water, but not with disinfectant to avoid corrosion.

Or put some white vinegar on a clean rag, or remove the blackened substance, or soak it in coke or strong tea overnight. After the bracelet is restored to its original state, wash it with clear water. If it can't be removed, it can be sent to specialty store for cleaning.

What happened when I bought the silver bracelet? 3 1. Silver naturally oxidizes in air to form silver oxide, which is brown or grayish black. In other words, if the air quality in our environment is not good, it will contain some acidic gases such as hydrogen sulfide, and silver will react with sulfur in the air to produce silver sulfide.

2. Human sweat contains sulfur, but everyone's physical condition is different, so the result of wearing silver ornaments will be different for everyone. Some people's body fluids contain high acidity and sulfur content, which will lead to the blackening of the surface of silver ornaments. People with weak acid constitution do not raise silver, and silver tends to turn black.

3. If the items you usually contact contain high acidity and sulfur, it will also lead to black and silver jewelry. For example, smoking all the year round, wearing perfume, wearing heavy make-up, often using sulfur soap and soaking in hot springs will all affect the color of silver jewelry.

4. Silver and gold cannot be worn together, which will cause silver to turn yellow and lose its luster.

5. The silver jewelry purchased is insufficient in silver content and contains more other metal elements. These oxidizable metals are easily oxidized by air, making them black.

I think there are two kinds of people who think it is relevant and irrelevant, about 50% each. Don't jump to conclusions yet. Let's look at the report of biological research first. A new study published in the journal lmmunity illustrates how immune cells manage themselves, and its source is unexpected hydrogen sulfide, which is what we usually call rotten egg-flavored gas. Hydrogen sulfide is produced by muscle cells and is closely related to diseases such as immune regulation, cancer and hypertension.

When our body is carrying out immune response, muscles will produce more hydrogen sulfide gas. When we are sick, our immune system will have many immune reactions to protect the body, producing more hydrogen sulfide gas, which will obviously blacken the silver ornaments.

Therefore, people who are often sick, silver ornaments may be more likely to turn black. But the blackening of silver ornaments has nothing to do with getting sick. Quote the attending physician of internal medicine of Jiangxi Provincial Hospital of Traditional Chinese Medicine: "Wearing silver jewelry is black, which is mostly related to personal physique, but not absolutely related to health."

Under normal circumstances, the surface of silver jewelry will naturally oxidize after being worn for about half a year, and the color will become dull and lose luster, which is inevitable for almost all silver jewelry. Therefore, you can't judge your physical condition according to whether wearing silver jewelry turns black or not. The best way is to go to the hospital for examination.

Second, why are some people getting smarter?

1, the first is less sweating and less acid and sulfur secreted by the human body.

2. Then, in the daily wearing process, silver ornaments often have unconscious friction with the human body. Shaking jewelry is equivalent to polishing silver jewelry in disguised form, which will gradually eliminate the black oxide film on the surface.
