The silver bracelet is discolored and healthy. Handstring is a common ornament, and many people like to wear it. There are many styles of bracelets. Common styles include blessing bracelets, safe bracelets, princess bracelets, bracelets of beautiful women from south workers, handcuffs from north workers and so on. Wearing bracelets is good for your health. Let's share the discoloration and health of silver bracelets.
Is the discoloration of silver bracelet related to health? Is the blackening of silver bracelet related to health?
It has nothing to do with the body, but the silver is oxidized.
The blackening of silver bracelets has little to do with health.
Although silver is an inactive element, it easily reacts with many substances in nature. The most common chemical reactions occur in:
1, and react with hydrogen sulfide in the air;
2, reacting with elemental sulfur;
Third, it reacts with some toxic gases.
Therefore, after a long time, there will always be some black substances on the surface of silverware whether it is worn on the body or not.
The silver bracelet is mainly worn on the wrist, which is very loose in contact with the skin. If you want to blacken the silver bracelet, there must be a lot of toxins in your body, and with such a big toxin, people would have died long ago.
It can be seen that the blackening of silver bracelets has little to do with health.
Discoloration of silver bracelets and health II. There is no direct relationship between the blackening of silver jewelry and health.
1 is determined by the nature of silver itself.
The chemical properties of silver are more active. If you encounter hydrogen sulfide gas or sulfur ions in the air, it is easy to generate a substance that is difficult to dissolve-silver salt, and chemical reactions can also occur when you encounter little hydrogen sulfide gas or sulfur ions.
Over time, silver salt will form a silver sulfide film on the surface of the silver ornaments we wear, and this silver sulfide film is gray-black, so the silver ornaments we usually see lose their original luster and gradually become gray-black.
2. Human factors will also affect the color of silver jewelry.
Everyone's endocrine structure is very different. Human sweat contains sulfur, so if the acidity of human sweat is related, if the sweat is acidic, the silver ornaments will turn black faster.
Because people sweat during exercise, a small amount of hydrogen sulfide will be produced in the body, and these trace sulfur compounds will react with the silver ornaments with sweat, which will lead to the blackening of silver ornaments, but this does not directly indicate that the blackening of silver ornaments is directly related to health.
3, hydrogen sulfide and other substances contained in the air.
The air will contain hydrogen sulfide, nitric oxide and other substances, which will oxidize the surface of silver ornaments, and then turn black and lose luster.
4. It is related to the silver content of silver ornaments.
There are many kinds of silver ornaments, among which snowflake silver is the best. Silver ornaments with high silver content and good material generally do not turn black.
Uncover the secret of ancient silver needle drug identification
In ancient times, the so-called poison identification mostly referred to arsenic, but the extraction technology was not perfect at that time. The method of extracting arsenic is to crush minerals, discard larger stones, and calcine with charcoal in a closed container to obtain white powder, so the extracted arsenic is not pure enough and will be mixed with a small amount of sulfur.
In short, wearing silver jewelry has many benefits, so you don't have to care too much about whether the diet you wear is black. The blackening of silver ornaments is a normal chemical reaction, which has nothing to do with your health, but with the pH of your sweat, your environment and so on.
Discoloration and health of silver bracelets III. The discoloration of silver ornaments only reacts with sulfur in the air and has nothing to do with health.
The chemical properties of silver make it easy to react with sulfur and hydrogen sulfide to produce black silver sulfide. The ancient silver needle antiquities are toxic because ancient arsenic is often used to poison. The main component of arsenic contains a small amount of sulfide, so the contact between sulfide and silver will produce a chemical reaction, which will make the silver ornaments black.
Silver can also react with oxygen in the air to produce brown-black silver oxide. At high temperature, the oxidation reaction rate is faster, and at room temperature, the oxidation rate is slower.
Secondly, if there are many compounds in the environment, such as silver jewelry, acid gas, hydrogen sulfide, nitric oxide and so on. Silver jewelry will react with these gases, causing silver jewelry to turn black. If silver jewelry comes into contact with a sweaty body or sulfide that is often released from egg products, it will turn black, giving people the illusion of helping themselves to detoxify, so this statement is incorrect.
Treatment method:
1, try to wipe the surface of silver with rubber, there will be slight black oxide after wiping.
2. Apply a little toothpaste on the silver surface, then wipe it with warm water, and then dry it with woolen cloth.
3. When the surface of silver jewelry is slightly corroded, gently wipe it with detergent or hot medium soap first, then clean it with soft cloth, and then dry it with flannel. At this time, the silver jewelry will show its original light.
4. Rinse with warm water, or rinse with solution, wet the surface with phosphoric acid solution, and then wipe with flannel to make the silverware cleaner brighter.
When silver is oxidized, it is light brown. You can wipe a little silver oil with Softbank cloth or soak it in silver water or wipe it directly with silver cloth.
Discoloration of Silver Bracelet and Health 4 What is the principle of ancient people using silver needles to detect poison?
One of the criteria for the ancients to identify whether food is poisonous is to see if it will turn black when touched with a silver needle. Because many poisons in ancient times contained sulfur, silver and sulfur would react chemically in the process of contact to produce silver sulfide. As an unstable salt compound, silver sulfide is grayish black.
So the silver needle turns black, which means that the food contains sulfur, and it also means that there may be poison.
Silver needles can't detect all poisons.
The silver needle poison test is only aimed at a small amount of sulfur-containing poison, but there are too many poisonous things in Daguan World, so the silver needle poison test is unreliable, so it mostly exists in unofficial history's novels, and there are few official records.
Does the blackening of the silver bracelet really mean that you are unhealthy?
Some people wear silver bracelets, the brighter they get, and some people turn black after wearing them for a few days. Looking at the blackened bracelet, I not only felt uncomfortable, but also suspected that my body was poisoned, so I was worried and tossed and turned, feeling guilty for failing this beautiful silver bracelet.
In this regard, experts said that whether the silver bracelet turns bright or black is not necessarily related to health. Some friends wear silverware brighter and brighter because there is no sulfur in sweat, while other skin secretions protect silverware instead;
And some friends wear silverware, which will make their skin black, just because there is more sulfur in sweat, which will react with silverware and turn black, which does not mean unhealthy.
How to solve the problem of silverware blackening
Because silver sulfide is a very unstable salt compound, it is not difficult to remove it. The common practice is to wipe the silverware with paper dipped in toothpaste, destroy this compound and restore it to its original state, and the silverware will naturally brighten.
Based on the above analysis, we can know that the blackening of silver bracelets is only related to personal physique, but not necessarily related to physical health.
