Tarnished silver. Tarnished (bottom) and untarnished (top) silver forks. Silver tarnishes slowly as sulphur compounds in the atmosphere react with the surface to form black silver sulphide (Ag2S). Certain foods with high sulphur contents,such as eggs,can cause silver cutlery to tarnish more rapidly | |
