Since the silver cross is often used as a wearable, the most frequent are the biological reactions that occur on the surface of the product when it comes into contact with the body. The presence of sulfur and copper atoms in the silver molecule contributes to the oxidation of the metal, which occurs when it interacts with water vapor and oxygen atoms.
The speed of the oxidative reaction depends on external environmental factors, the sweat composition of the human body, the frequency of contact of the product with various cosmetics.
Regular visits to the pool with chlorinated water also contribute to the rapid darkening of the cross.
