Human acquaintance with silver consists of millennium: noble metal mined and used in states that existed before N. NS. And today, silver is widely used in industry, medicine, for the manufacture of jewelry. Products made of silver metal look elegantly and exquisitely. Unfortunately, They can be covered with an ugly yellow raid.
Main reasons
Silver belongs to the group of noble metals, which are known for the fact that they practically do not react with other elements of the Mendeleev table. However, this is the most unstable metal of precious. Interacting with the environment, in contact with the human body and various objects, Silver is exposed to individual chemical elements and, as a result, darkens. This process is slow, which is somewhat accelerated in conditions of high humidity, at high temperatures, under the influence of light.
Without reacting to hydrogen, nitrogen, carbon, metal is quite sensitive to volatile sulfur compounds, for example, to hydrogen sulfide.
In the conditions of perfectly clean air with silver would not have happened. But in reality in the air there are always many compounds and substances. Sulfur is no exception.
One of its sources is human activity. For example, sulfur dioxide is formed when coal burning, in the process of industrial enterprises. The element is widely used as part of fertilizers, in medical preparations. In addition, it is present in many food products, in animals and vegetable organisms, in the household item around us. And this means that a small concentration of the element connections is always present, and we cannot exclude the interaction of substances. As a result, silver turns yellow.
It is difficult to overestimate the value of the sulfur for the vital activity of the human body . Especially it is a lot of muscle tissue, in the skin. And it is also known that there are a lot of sweat glands on the human body, allocations through which constantly occur. Among other products, along with then sulfur compounds are displayed. Therefore, it is not to be surprised that after a long wearing on the finger, the ring has become copper color, and the decorations that come into contact with the body (chains, earrings, pendants, bracelets) begin to yellow. The process is accelerating if there is a contact of jewelry with aggressive to silver means of household chemicals and cosmetics.
Silver yellow and under the influence of bromine or iodine. These elements are also present in many products, medical preparations. Bromine is used in the production of dyes for fabrics. There is another unpleasant reason, due to which the products can ship: you have acquired a fake from cheap metals, outwardly similar to silver.

In this case, yellowish spots will appear on the decoration.
