A report from the Jewelers of America highlights that the reagents in beauty and cleaning products can react with silver, thereby promoting tarnishing.
-
Storage Conditions: Improper storage can exacerbate tarnishing. Jewelry that is stored in damp or poorly ventilated environments is likely to tarnish more quickly. The National Jeweler suggests using anti-tarnish pouches or cloths to protect jewelry during storage.
-
Human Body Chemistry: Human body chemistry can also play a role in the tarnishing of sterling silver. The oils and acids produced by the skin can react with silver, promoting tarnishing. A study from the Journal of the American Society for Horticultural Science indicates that higher acidity levels in sweat can lead to faster tarnishing rates.
These factors collectively explain why sterling silver jewelry can tarnish and highlight the importance of proper care and maintenance to prolong its luster.
How Does Tarnishing Cause Sterling Silver to Look Copper?
Tarnishing causes sterling silver to look copper due to the presence of copper in its composition. Sterling silver consists of 92.5% silver and 7.5% copper. When sterling silver exposes to air and moisture, a chemical reaction occurs. The silver reacts with sulfur compounds in the environment. This reaction forms silver sulfide, which appears as a dark tarnish on the surface.
Over time, as the tarnishing progresses, the outer layer of silver may wear away, revealing the copper beneath. This action exposes the reddish-brown color of copper. The interplay between the silver and copper during tarnishing creates the appearance of a copper hue.
In summary, tarnishing causes sterling silver to look copper by revealing the copper content beneath the silver surface.
