Sterling Silver Identification:1Look at the color: 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 it contains copper, the surface of the jewelry will appear rough and the color will not be moisturized.

2.Weight: **Density is slightly greater than that of common metals, generally speaking:

Aluminium is light, silver is heavy, and copper is not light and not heavy. Therefore, the weight can be weighed to make a preliminary judgment on 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.

3.Check the hardness: **The hardness is lower than copper, and larger than lead and tin, and you can use a pin to scratch the inconspicuous place of the jewelry for testing, such as the needle is slippery, and 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.

4.Listen to the sound: sterling silver jewelry is loud, 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.

5.Hydrochloric acid method: file a small gap in the silverware with a knife, and point the hydrochloric acid on the notch to observe its changes. More than 95% of sterling silver, white remains unchanged, 80%-95% of silver becomes black, 50%-75% of silver becomes green, and the darker the green, the lower the content.

The density of silver is different from that of other metals, and the density of real silver is that it can be detected by weighing. 2.Tested for the solubility of silver, real silver can be dissolved by nitric acid, while fake silver generally cannot be dissolved.

3.See if there is a "925" silver mark. 925 sterling silver, also known as sterling silver, is made up of silver and other alloys (usually copper).

4.The appearance of silver bars and silver coins is carefully distinguished, and the color of real silver is elegant, soft, and has a pearlescent effect; The color of the fake silver is too smooth and shiny to be easily seen. 5.

The hardness of silver is very small, when the surface of the ** product is scraped with a silver needle, if it cannot be scratched, it can be judged as pure silver. However, please note that different surface treatments such as silver jewelry, silver bars, and silver coins, as well as different silver contents, will also have different effects on the identification, so comprehensive identification should be carried out according to the specific situation. Hope it helps.

The purification of tap water often contains bleaching powder or chlorine, which has a serious erosive effect, and the eroded ** loses its luster and produces white silver chloride. Therefore, it is not advisable to wear ** in the bath. 6.
