How to distinguish true and false silver is very simple.

The simple methods to identify the authenticity of silver are color, hardness, temperature, specific gravity and mark.

1, color:

The higher the fineness of silver, the bright white metallic luster appears on the surface, which looks like polishing and is not easy to fade, while the surface color of fake silver is dark and dull, which looks dull and stiff.

2. Hardness:

The higher the silver content, the softer the texture and the easier it is to deform, so avoid touching hard objects at ordinary times. If you bite with your teeth, it is easy to have obvious marks, while fake silver has low color, high hardness and is not easy to deform.

3. Fire:

Pure silver will generally turn white after burning, but it will not turn black. If it turns black, it means it is not pure silver. Burning silver with a lighter may blacken the silver. At this time, brushing teeth with toothpaste can turn white again. As long as it can burn black, it is basically not pure silver.

4. Specific gravity:

Generally speaking, true silver has high density and high specific gravity. If you weigh it carefully in your hand, there is obvious oppression, while fake silver has low silver content, low density and small specific gravity. It's not obvious to hold it in your hand.

5. Mark:

According to the relevant international regulations, real silver ornaments are generally marked, such as S925, AG925, S990 and AG990, while fake silver ornaments are usually not, so that they can be better distinguished.

The use of silver

1, jewelry making:

Silver is a very popular jewelry material, which is widely used to make all kinds of jewelry, such as necklaces, bracelets, rings, earrings and so on. Silver has excellent processability and can be used to make various exquisite jewelry styles.

2, industrial manufacturing:

Silver is also widely used in industrial manufacturing, such as electrical, electronic, aerospace, medical and other fields. Silver has good electrical and thermal conductivity and can be used to manufacture various electronic components and equipment. In addition, silver can also be used to make various high-performance alloys and materials.

3. Investment and collection:

As a precious metal, silver is also widely used for investment and collection. Silver bars, silver coins and silver ornaments can all be used as investment and collection objects.
