Why Silver Turns Black On The Body? - Steemit

Silver jewelry is loved by many. Each holder of notes that over time, silver turns black on the body. Why is this happening? What is the reason? Some attribute this to the properties of the metal itself. Others are convinced that darkened silver indicates a serious illness in humans. Who is right?

 Properties of metal

The composition of silver containing copper, which is entering into cooperation with the salt then gives the person the oxidation reaction. The result of the collapse in the course of this oxidation is a darkening of the metal. In fact, the salty sweat - it is pure hydrogen sulfide, which speeds up a chemical reaction. That is, no matter where you wear silver jewelery, it certainly will darken over time. The exception, perhaps, ears, where sweat can occur in very rare cases. As a result, silver earrings, located on the ears, virtually do not darken.

Many owners of the silver mark, and the second important property of the silver - after the darkening automatically returns to its original color. For certain researchers do not yet know why this is happening. Maybe it's some kind of mystic?

However, it is noted that the higher the silver sample, the less it darkens the skin. Thus, silver jewelry 999 practically does not change its color over the years. Silver is 875 samples can dramatically darken after a few days wear on the body. The higher the proportion of copper impurities in the composition, the earlier decoration will change color. In addition a dark shade it can be reddish or rusty.

Usually it is easy to fix by simply brushing decoration. For example, in the home with this copes regular toothpaste with menthol. If the decoration strongly darkened, it can simply be soaked in a soda solution at night.

And why silver turns black on the body of the first day? All of this may be due to the peculiarities of the human body.

Health and silver

Any disease in humans causes a temperature rise or decline. Even minimal change in these rates may have an impact on the composition of the blood. This in turn distorts and the sweat. Hydrogen sulfide begins to stand out even more, the reaction proceeds faster. As a result - the silver darkens instantly.

In addition, some people on the nature of the modified Ph-skin due to chronic diseases. Silver, as the metal complex from the composition, the skin quickly responds. Using a new lotion or body cream it may also be noted that silver begins to darken. New soap or shower gel, too, can give such a result.

Sometimes darkening Silver jewelry is associated with kidney or liver disease. Again due to the fact that the blood in the human body is modified. In cases where hormonal changes, ornaments are also starting to get dark. During pregnancy, women often marked by dramatic darkening of the chains, crosses, pendants made of silver. Breast sebaceous glands secrete the most abundant hydrogen sulfide. May affect the browning and taking certain medications that contain hormonal substances.

It was also observed that the external environment influences. So, if the soil in the area where you live, contains large amounts of hydrogen sulfide, the decorations will darken quickly. Including earrings.

Visiting a sunbed or the pool, be ready that silver jewelry will change color very quickly. Influence of ultraviolet rays does not affect properties of silver in any way, but force a human body to emit notorious sweat. Water contains a large amount of chlorine and impurity which cause darkening of jewelry in the pool.
