Why Does Metal Jewelry Tarnish Over Time?
Metal jewelry tarnishes over time mainly due to a chemical reaction with environmental factors. This reaction typically involves exposure to moisture, air, and certain substances in the environment.
The American Gem Society, a reputable organization in the jewelry and gemstone field, defines tarnish as a surface discoloration that affects metal. This discoloration occurs when metal reacts with sulfur, oxygen, or salts in the air and moisture.
The underlying causes of tarnishing include oxidation and sulfur exposure. Oxidation occurs when metal reacts with oxygen, resulting in a layer of oxides forming on the surface. Sulfur compounds, which are often found in pollution or even common household items, can cause a reaction with metals like silver, leading to the formation of silver sulfide, the black tarnish we see.
Oxidation is a natural process that affects many metals. For example, when copper is exposed to oxygen, it develops a green patina, known as verdigris. Silver, on the other hand, reacts more readily with sulfur, creating tarnishing that can appear as various shades of black or brown.
Specific conditions that contribute to tarnishing include high humidity, exposure to sweat, and contact with certain products such as lotions, perfumes, or even cleaning agents. For example, wearing silver jewelry while swimming in chlorinated water can accelerate tarnishing due to chlorine’s chemical properties. Enclosed storage in damp environments can also increase humidity, further promoting tarnish formation.
In summary, metal jewelry tarnishes over time due to chemical reactions with environmental factors, particularly sulfur and oxygen. Specific conditions or actions, like exposure to moisture and certain substances, can exacerbate this issue, affecting the jewelry’s appearance.
