Why Does Silver Tarnish?

Silver reacts with sulfur compounds in air or sweat:

4Ag + 2H₂S + O₂ → 2Ag₂S (black)

Silver sulfide forms a black film on the surface. This isn't rust—it's natural to all silver, even ancient silver artifacts excavated today are black.

Who Tarnishes Faster?

• People with high-sulfur sweat (high meat diet, athletes)
• Hot spring / swimming pool exposure (chlorine)
• Sulfur soap, sulfur skincare products
• Humid environments (rainy season in the south)

Standard Customer Service Script

"Hello, tarnishing is a natural physical property of pure silver, not a quality issue. Silver reacts with sulfides in air to form a black silver sulfide film. Simply polish with a silver polishing cloth to restore shine. Avoid hot springs, perfume, and sweat to slow tarnishing."
