What is difference between oxidized silver and sterling silver?
Dengan baik, oxidized silver is a misnomer. It sounds that you purposely oxidized silver to make oxidized silver. The truth is that pure silver or 99.9 percent pure silver is a very reactive metal. It reacts with atmospheric oxygen to form silver oxide which forms a black layer on pure silver. This gives the proof of its purity and the black color leads people to call it oxidized silver. Pure silver due to its reactivity is not suitable for cutlery or jewelry because it gets tarnished easily by exposure to air.
Perak sterling adalah paduan dari 92.5% silver and rest copper. This alloy does not get oxidized easily that is why it is used for jewelry and cutlery.
