Tarnish is a term used to describe the process of dulling or discoloring the surface of a metal, typically due to exposure to air or certain substances. It refers to the formation of a thin layer of corrosion or oxidation on the surface of the metal, often giving it a dark or dull appearance. Tarnishing results from chemical reactions between the metal and oxygen, sulfur, or other compounds present in the environment.
Usually, metals like silver, brass, copper, or aluminum are more prone to tarnishing than others. This can occur over time as the metal is exposed to moisture, pollutants, or acidic substances. Tarnish can also be accelerated by factors such as humidity, high temperatures, or contact with certain chemicals or materials.
The tarnishing process can be visually recognized by the appearance of a layer or film on the metal's surface, which alters its original shine or luster. Tarnish is typically removed through the use of cleaning agents or techniques specifically designed to eliminate the corrosion or oxidation buildup. These methods help restore the metal's original appearance and prevent further deterioration.
In a broader sense, the term "tarnish" can also be used metaphorically, referring to the damage or deterioration of a person's reputation, character, or image due to specific actions, associations, or events.
To diminish the lustre or purity of; to sully; to stain; to soil; to become dull or dim.
