Anonymous users2024-02-11How to check sterling silver at home:
1. Identification method of burning silver: first put silver bars and silver bars.
Put it on the gas stove and burn it red, and then put the red-hot silver bars and silver nuggets into cold water, the sterling silver is white, and the impure silver will turn black, this method can only identify whether the purity of the silver reaches 99%, and can identify small pieces such as real and fake bracelets. The melting point of sterling silver is 960 degrees, so you can burn it boldly with confidence, and the fire of the gas stove cannot melt the silver nuggets.
2. Observation.
Look at the color of the silver: the higher the purity, the whiter the silver, and the surface of the jewelry looks even shiny and polished. If it contains lead, the jewelry will take on a blue-gray color. If copper is contained, the surface of the jewelry will appear rough and the color will not have a sense of moisture.
3. Weighing method, silver jewelry.
Weight: **Slightly denser than common metals, generally speaking: "Light aluminum, heavy silver, not light and not heavy.
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.
4. Specific hardness, check hardness: **The hardness is lower than copper, and larger than lead and tin, and can be tested in an inconspicuous place with a pin, if the needle is slippery, it is difficult to leave traces on the surface, it can be judged as 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.
5. Listen to the sound and rhyme: the 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.

Anonymous users2024-02-07To test whether it is sterling silver at home, you can first distinguish it from the color, which looks white and shiny, and the workmanship is fine, indicating that the purity is also higher. It can also be distinguished by weight, because silver has a higher density and is heavier than ordinary metals. You can also burn it with a lighter, after burning to 5 10 seconds, if the flame of the lighter turns green, it means that the thing is fake, and if the flame is still the primary color, it means that it is real.
