Look at the color:
The higher the purity, the whiter the silver appears. The surface of the jewelry looks uniformly shiny and has a luster. If it contains lead, the jewelry will appear bluish-gray; if it contains copper, the surface will look rough and lack luster.
Weigh it:
Silver has a slightly higher density than commonly found metals. Generally speaking: 'Aluminum is light, silver is heavy, and copper is neither light nor heavy.' Therefore, weighing can provide a preliminary judgment on whether it is silver. If the piece is large but lightweight, it can be preliminarily judged to be made of other metals.
Check hardness:
Silver has lower hardness than copper but higher than lead and tin. You can test inconspicuous areas of the jewelry with a pin; if the pin slides easily and leaves little trace on the surface, it can be determined to be made of copper; if it's lead or tin, traces will be obvious and prominent; if there are traces left that are not very obvious, it can be preliminarily judged to be silver.
Listen to the sound:
Pure silver jewelry makes a clear sound when dropped, with no elasticity, producing a sound like 'pada pada'. The lower the purity, the lower the sound; if it's copper, the sound is high-pitched and sharp with a quick and short resonance; if it's lead or tin, then the sound when dropped is dull and short with no elasticity.

Prevent silverware from turning black: Hydrogen sulfide and sulfides cause silverware to tarnish. Due to the presence of sulfur in the air, certain foods (such as vegetables, eggs, etc.) contain hydrogen sulfide. It is essential to clean silverware as soon as possible after use to avoid sulfide formation (commonly known as oxidation).
