The silver ornament has a beautiful and gorgeous appearance and is deeply loved by the public. But it's easy to get black after a long time. Do you know why? Is it really to absorb the toxins in the body? Follow Xiaobian to learn about it.
Some people think that the reason why silver ornaments turn black is that silver ornaments will absorb the toxins released by human detoxification, and the worse the body constitution, the darker the silver ornaments will become. Is this true? Why do silver ornaments turn black slowly after wearing silver ornaments for a long time?
First of all, let's explore the truth of the statement that the blackening of silver jewelry is due to the absorption of toxins from the human body, and the worse the body constitution, the blacker the silver jewelry. Some studies have shown that silver jewelry is difficult to absorb toxins secreted by human body because of its oxidation resistance and durability of luster. Therefore, there is not much relationship between the blackening of silver ornaments and the wearer's physique, let alone the saying that people with good health will wear silver ornaments more brightly, while people with poor health will wear pure silver jewelry.
So what's the reason for the blackening of silver ornaments?
In fact, blackening of silver ornaments is a normal natural phenomenon, because sulfur and oxides in air and other natural media have certain corrosive effect on silver. After wearing for a period of time, there will be some small spots (silver sulfide film), which will spread into pieces or even become black in a long time. Therefore, there are some discoloration phenomena of silver ornaments due to oxidation at present. In addition, the silver material will also affect the degree of blackening. There are many kinds of silver, such as Miao silver, Thai silver, Tibetan silver, snow silver, etc., of which the better one is snow silver. Different silver jewelry has different silver content. Bracelets with high silver content and good material are generally not blackened when wearing them. Pay attention to the general and special circumstances.
Therefore, when you wear silver jewelry, you should avoid touching water vapor and chemicals, and avoid swimming, especially going to the sea. After wearing it every day, wipe it with cotton cloth and put it into jewelry box or bag for sealing.
If the silver ornament has been oxidized and blackened, it can be washed with a soft brush dipped in toothpaste, or it can be washed by hand rubbing soap or detergent. In a word, the reason why silver jewelry turns black is that pure silver jewelry can react with sulfide in the air. There is no saying that silver jewelry turns black is related to human body constitution. Therefore, it is suggested that you should take good care of the silver ornaments when you wear them at ordinary times, so as to reduce the possibility of oxidation reaction and blackening of the silver ornaments.
