These small, chemically treated pieces of material are designed to mitigate the oxidation of sterling and fine silver. Placed alongside stored silverware or jewelry, they work by absorbing airborne pollutants, primarily sulfur compounds, that cause the discoloration known as tarnish. For example, a strip placed inside a silverware chest or jewelry box will help keep items bright and shiny for extended periods.
Their significance lies in preserving the aesthetic and monetary value of precious items. By inhibiting the tarnishing process, they reduce the need for frequent and often abrasive cleaning, which can gradually damage delicate surfaces. Historically, preventing silver tarnish was a labor-intensive process involving polishing with specialized cloths and creams; these strips offer a simpler, more passive solution.
