Silver is one of the richest on mysticalmetal values. It is used both for decorations and in ceremonial acts in Christianity. Also used by his followers of all kinds of occult sciences. It is believed that this metal is clean, can protect its owner from the effects of evil spirits, slander and evil eyes. It is with this that almost all the sorcerers explain why the silver cross turns black on some people. Say, they jinxed them, so the metal reacts.

Another common opinion is whyThe silver cross is blackened; it is a link between silver and diseases of the body. It is believed that the darkening of these ornaments signals of diseases of the liver and kidneys. However, there is no scientifically confirmed data on this subject. One thing is definitely known - the reason why the silver chain turns black, the cross and other decorations, is a chemical reaction. Yes, yes, it all comes down to conventional chemistry. The fact is that any silver products contain copper, which is highly oxidized. And the main oxidizer for it is the usual human sweat, or rather the amino acids contained in it, which include sulfur compounds. They cause the reaction.

Then the question immediately becomes ripe:"Why does not the silver cross blacken at all and not always?" To answer it, one should also recall the lessons of anatomy. Each of us has a different composition of sweat. It is defined as a hormonal background, and the general state of the body and metabolism. It happens so that when hormonal storms occur in the human body, when metabolism accelerates or simply when physical exertion increases, lifestyle changes, diet or place of residence change, the composition of sweat begins to change. Accordingly, the level of amino acids also changes or, as it sounds familiar, the level of acidity of sweat changes. With an increase in this level, silver oxidation processes begin to occur more actively.
