5 thoughts on “How to test the silver is true or false?”
Lester
There are four methods to distinguish between true and false silver: 1. Different from color. The higher the purity, the more white, the more bright and bright on the surface. The leading silver will show blue and gray. The copper -containing silver, the surface will appear rough, and the color is not moist. 2, discern from the sound. This silver is thrown on the ground with no elasticity. The lower the silver, the lower the sound, but the higher the tone, the higher the pointed, and the rhyme. If it is copper, its sound is higher and sharp, and the rhyme is short and short. If it is a lead and tin texture, the sound is dull, short, and non -elastic. 3, identify from hardness. The silver hardness is lower than the hardness of copper, higher than lead and tin hardness. It can be tested with the inconspicuous places of jewelry. If the needle is slipped, it is difficult to leave traces on the surface, and it can be judged as copper. If it is a lead and tin texture, the traces are obvious and prominent. This left with traces without obvious, and it can be preliminarily determined as silver jewelry. 4, identify from weight. The silver density is larger than many metals, so the weight can make a preliminary judgment on whether it is silver. If the jewelry is large and weighs lighter, it can be preliminarily determined that the jewelry is other metals. The expansion information: The silver jewelry sold on the market mainly includes three types: "925", "990" and "999". The highest purity is "999", called thousands of foot silver, with a silver content of 99.9%, but it is easy to oxidize and turn black. You need to wear it carefully. The second purity is "990", called foot silver, with a silver content of 90%. "999" and "990" are suitable for making silver jewelry due to high silver content. The most common on the market is "925" silver, also known as international standard silver, which is the minimum standard for sterling silver in the world. "925" silver added 7.5%of copper alloy ingredients, which increased hardness and more suitable for flower jewelry.

1. Color method: Observe with the eyes, it looks white, shiny, and finely worked, is a high -colored silver jewelry; poor color, mostly downed for fake silver jewelry. 2. Bending method: lightly folded silver jewelry with your hands, easy to bend and not easy to break; stiff and barely folding color is low; Baoyin jewelry; it can't stand the light folding, and it is easy to be fake. 3. Nitric acid identification method: Use glass rod to drip nitric acid at the mouth of the silver jewelry, which is brown rice and slightly green. 4. Throwing method: Throw the silver jewelry from top to bottom on the table. The bouncing is not high, and the sound is stable as a high -colored silver jewelry; , Fake or low -colored silver jewelry.
Only by destroying silver jewelry to use chemical methods can the true and false and disadvantages of silver jewelry be detected. Is there any relevant certificates, certificates, and certificates for silver jewelry. Only the silver jewelry detected by the testing agency can buy it with confidence. In addition, the silver content of silver jewelry must be accurately indicated that consumers should check whether there are "925" on the jewelry when purchasing. "925" is a symbol of sterling silver.
