Silver is often used to make jewelry and ornaments. However, a common problem with silver is surface oxidation or "tarnishing." To prevent or at least reduce this effect, various alloying elements are added to silver.
Silver is used in the manufacture of many decorative items, from jewelry to accessories, musical instruments and cutlery; Its bright color makes this metal particularly attractive for such applications. The most popular alloys typically consist of 825, 925 (Sterling), or even 935 parts per thousand of silver and copper by mass. Cu is added to increase the strength and machinability of the material.
Although silver is a precious metal, it tends to oxidize on the surface, discoloring its shiny face with a dark, dull stain. This effect, called blackening, is also seen in copper alloy silver.
What is a gold silver alloy?
An alloy is obtained by adding silver and copper to the gold used in the jewelry industry. This alloy also contains a small amount of zinc. Gold, silver and copper alloys also differ in color. The amount of gold and the ratio of silver to copper are important in the alloy that appears as yellow, red and green.
Therefore, the focus of many R&D has been to improve the tarnish resistance of silver through the addition of various elements, including precious metals such as Palladium and semi-metals such as Germanium, among others.
Does silver alloy tarnish?
Silver tarnishing occurs due to the materials used for easy processing of silver. It is a metal that is suitable for tarnishing due to its silver structure. The answer to the question of whether silver will tarnish is the tarnish caused by sulfur, sulfuric and hydrogen in the air.
Does water damage silver?
Silver oxidizes and tarnishes quickly. The reason for this is the hydrogen, sulfur and sulfuric acid in the air. In addition, perfume, cologne, etc. used with the sweat produced by the human body. chemical products cause silver jewelry to change color faster.
What is silver cleaned with?
Baking soda and vinegar water cleans silver jewelry and helps them regain their first day's shine.
