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.
3. Check the hardness: the hardness of silver is lower than that of copper, but higher than that of lead and tin. You can use a pin to mark the jewelry in an inconspicuous place to test it. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry.
