Weight: **Slightly denser than common metals, generally speaking: "light aluminum, heavy silver, not light and not heavy copper."
Therefore, the weight can be preliminarily judged whether it is **. If the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry belongs to other metals.
Check the hardness: **The hardness is lower than copper, and larger than lead and tin, you can use a pin to scratch the inconspicuous place of the jewelry for testing, if the needle is slippery, it is difficult to leave traces on the surface, it can be judged to be copper jewelry; If it is lead and tin texture, the traces are obvious and prominent; If there are traces of the physical object and it is not obvious, it can be preliminarily judged to be ** jewelry.
Listen to the sound rhyme: Sterling silver jewelry has a sound on the ground, no elasticity, and the sound is "Porphyry". The lower the color, the lower the sound, and the sharper and higher the voice, the higher and rhyme; If it is copper, its voice is higher and sharper, and the rhyme is rapid and short; If it is made of lead or tin, the sound of throwing the ground is dull, short, and has no elasticity.

How to identify silver or silverware???
First of all, make a statement: only use the ordinary methods around you to test the silver, only one can be detected, if you want to identify accurately, you still need to go to a professional quality inspection center for identification. There are a few small ways to do this.
1. Put a drop of bleach on the silverware. Take a closer look at the changes that occur on the surface of the silverware. If the silverware immediately darkens or turns black, then the silverware is of higher purity.
Because silver is highly oxidizing, silverware can immediately become dull as soon as it comes into contact with an oxidizing agent like bleach.
2. Use coins to do a sound test. Silverware makes a pleasant bell-like sound when it is collided with other metals, especially when it collides with other metals. If you want to do this test, you must first find a coin issued during the Ming and Qing dynasties, because most of the coins issued during that period were silver, and in New China, the coins were mostly nickel.
Silver coins have a crisp sound when struck, while nickel coins have a dull sound when struck.
Be gentle with your hands and feet, especially with coins, as it is easy to leave a mark on the silverware. If the silverware makes a crisp sound, it means that it is **; If it is a dull sound, then it is likely that the silverware is mixed with many other metals.
I hope this helps, thank you for your interest!
