This happens not only during long-term storage, but also when worn. Many are interested in the question of why this happens and whether this is a consequence of health problems, which is confirmed by superstition. In this article, we will examine a scientific explanation for this process and explain why silver can change color.
Signs and superstitions
Since ancient times, people believed in all sorts of signs and superstitions. It was believed that if the silver pectoral cross began to lose its shade, it means that the person was spoiled or he was jinxed. If the decoration began to lighten, then the negative impact on the person became less. When the product returned to its original form, then the damage has lost its strength. According to legend, silverware is able to protect from evil eyes, evil spirits, so they were used in various rites. The blackening on the jewelry was explained in different ways.
Here, it was taken into account on which part of the body the jewelry was located, and the type of accessory, and even the age of the person.
- It was believed that if the ring blackens, then the girl has a vow of celibacy, and the matchmakers are unlikely to knock on her.
- In the event that the chain on the neck or earrings is getting dark, then the evil eye is on the girl.
- If the cross located on the body changed color, then it was believed that the curse is very strong.
- When the color of the cross on the neck of a young child changed, the jewelry should be taken to church and consecrated again to protect the baby.
- If the dishes made of silver became darker, they said that the house has negative energy, which indicates the presence of evil spirits.
There is a belief that silver absorbs all the bad energy. If such jewelry or dishes changed color, it means that this person was in danger and could avoid it, because silver attracted the danger.
Scientific explanation
It used to be that products began to blacken, if a person is sick. This is partly true. With hormonal, endocrine and other disorders, a person begins to sweat harder, which leads to a stronger interaction of the sebaceous glands with sweat. The interaction of sulfur-containing compounds leads to a change in the shade of the products. Silver oxidation occurs during the reaction of a metal with hydrogen sulfide and oxygen.
In its pure form, silver is practically not used for making jewelry, because this metal is quite soft. It is usually customary to mix harder metals, such as copper. Often, silver begins to darken if a person often sweats. With the interaction of copper, which is part of the jewelry, and sulfur contained in the sweat, a chemical reaction begins to occur, as a result of which the products begin to become covered with a patina, that is, get dark.
In that case, if a person has no health problems, then the amount of sweat released is normal, and an oxidative reaction does not occur. But if sweat begins to be released more intensely, then the product located on the body began to change its hue. These situations can enhance oxidation.
- Stress.
- Physical exercise. With active sports, sweating intensifies, which leads to an increase in sulfate concentration. This leads to a faster darkening of the jewelry.
- High humidity. Then the evaporation of sweat slows down, therefore, the concentration of sulfur salts increases. Based on this, oxidation begins to occur, which leads to a change in the color of the product.
- The presence in the products of a large number of various impurities. Sample of silver also plays a significant role. Sample 925 products are usually less susceptible to oxidation. The higher the sample product, the less it will be susceptible to corrosion. From the content of impurities depends on how long the product will be worn without changing color.
Silver, having a low sample, begins to darken faster, while oxidation begins to occur even when in contact with food or when sulfur compounds are in the air.
It is interesting that the interaction of sweat with silver leads not only to its darkening, but also to lightening.
In addition to sulfates, sweat contains nitric acid salts. When interacting with nitrates, silver sulfide begins to break down, and the product quickly changes its dark color to light.
