Why does silver turn black: body signals
It happens that your favorite silver jewelry suddenly begins to turn black. As a rule, there is no particular visible reason for this, but silver still turns black. Moreover, this happens regardless of how long ago the jewelry was purchased. The Land of Soviets decided to figure out why does silver blacken on a human body.
Humanity has known about the various properties of silver for a long time. Everyone knows that silver ions contribute to the death of bacteria, that is why silver cutlery is very valuable, and it is silver things that are used in religious rituals.
To the question of why silver turns black, folk wisdom has found a completely explainable answer - spoilage. Like, your ring has darkened, it means you are wearing a crown of celibacy, earrings are a strong evil eye, and if your pectoral cross has darkened, you don't even want to think about it.
Of course, you can believe this interpretation, but there is a more scientific, and accordingly more serious an explanation of why silver turns black.
The fact is that the silver jewelry that we used to wear contain copper. Copper oxidizes under the influence of humid air, sweat and other external factors. Silver itself belongs to the noble metals. Under the influence of the same external factors (water, humid air) plaque forms on the surface of the silver item silver sulfide, gradually it thickens, and the silver jewelry darkens.
The rate at which plaque forms on silver items can be associated with both external reasons, which include climate change, increased air humidity, frequent contact with water, contact with certain substances on the product, and with internal processes organism. Especially if you wear silver jewelry all the time.
If not all the silver jewelry that you wear darkens, but only some, then it’s not a matter of external factors, but of your body. There can be many reasons why the silver chain around the neck darkens, but don't sound the alarm right away. Listen to your physical condition and notice which jewelry has darkened.
Most of the sebaceous glands in a person are located on the chest. That's why first of all, chains and pectoral crosses turn black. And this is due to increased sweating, and not with the evil eye and spoilage. Darkening of the jewelry on the chest most likely indicates hormonal changes in the body. For example, during pregnancy. In this case, the chain can darken very quickly, in just a few days.
In addition, the reason may be severe stress, emotional stress or worries. All this also affects the work of the sebaceous glands, and, accordingly, increases sweating, which makes silver and darkens. Perhaps the silver has darkened due to taking any medicinal product, which contains sulfur compounds.
There is a version that darkening of silver indicates malfunctioning of the kidneys or liver. The lightening of silver can also indicate this, since in this case, substances containing nitrogen are released with sweat, and it gives the silver a shine. In addition, a discoloration of silver may indicate a problem with the nervous system. And the darkening of silver items on certain parts of the body can tell about local failures in the work of the endocrine system.
There is a more prosaic explanation, why does silver darken on the human body: physical activity, heat, contact with certain chemical compounds.
Try to do not play sports, do not go to the bathhouse and do not swim in silver jewelry. This will help keep them from darkening. And if in this case the silver still turns black, you should pay attention to your health.
