Look at the color:
The higher the purity, the whiter the silver, and the surface of jewelry looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist.
Weighing:
The density of silver is slightly higher than that of ordinary metals. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is silver by weighing. If the jewelry is large and light, it can be preliminarily judged that the jewelry belongs to other metals.
The extended information includes electroplating pure silver ornaments, that is, the inner layer is pure silver, and the surface is being treated with current; Electroplating is generally divided into electrogold and platinum; The way to identify electroplating is that its surface is brighter than pure silver, just like a mirror, which has good reflective effect and is not easy to oxidize (the oxidation time depends on the thickness of electroplating).
Electroplated silver jewelry is easy to lose its luster due to vulcanization (sulfur dioxide in the air reacts with silver to form a layer of silver sulfide on the silver jewelry, just like an apple will slowly turn black after being cut).
