How to distinguish the real from the fake, and how to distinguish the true from the fake

Methods for distinguishing silver from real silver:1The higher the purity of the color, the whiter the color, and the surface of the jewelry will look uniform and shiny, with a polishing effect.

If it contains lead, the jewelry will have a blue-gray color; If copper is present, the surface of the jewelry will appear rough and the color will not feel moisturized. And if it's real silver, the color of the silver won't change after burning. If it is fake silver or silver of too low purity, the color will turn black when burned.

2.Weighing silver is slightly denser than common metals. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy."

Therefore, weighing can preliminarily determine whether it is silver. 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 Silver is less harder than copper but greater than lead and tin. This can be done by marking the jewelry in an inconspicuous place with a pin. If the needle is slipped, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead or tin, the mark is clearly prominent; If there are traces in the physical object but it is not obvious, it can be preliminarily judged to be silver jewelry.

4.Listen to the sound. The authenticity of ** can also be judged by the sound.

Standard silver jewelry sounds bland when it lands. Silver is generally softer. If it falls on some hard objects, it will make some faint sounds.

If it's other metal, it makes a lot of noise. 5.Look at this mark, generally silver jewelry should be stamped with the English abbreviation of silver ("S" or "AG").

The standard silver stamp is S925. The stamp of pure silver is S990.

How to distinguish the real from the fake in silver:

1. Fire burning method.

Real silver will not change its silver color after being grilled over fire, but if it is fake silver, it will turn black after grilling.

2. Nitric acid test method.

Drop a few drops of nitric acid on the surface of silver jewelry, wipe it off after a while, if the surface of the jewelry is still silvery-white, it means that the silver content is quite high, it is real silver; If it is a jewelry with a low silver content, it will be grayish-black, so it is fake silver.

3. Sound judgment method.

Silver is softer, and when you throw silver jewelry on a hard object, the sound it makes is weak, the sound is dull, it doesn't bounce, it doesn't roll. If it is a fake silver jewelry, it will make a crisp sound and the bounce will be relatively high.

4. Bending method.

Bend silver jewelry with both hands, if it is real silver jewelry, it is easy to bend and not easy to break. If it is a fake silver jewelry, it will feel hard when bent, or it can only be barely folded, and some can not even be folded. Generally, real silver jewelry will crack when bent or knocked with a hammer a few times, and fake ones cannot withstand bending and are easy to break.

5. Magnet attraction method.

Magnets are magnetic substances, substances containing iron can be attracted, if it is a real jewelry can not be attracted by magnetic substances, if it can be attracted by magnets silverware generally contains impurity metals, low purity, is a fake silver jewelry.

You can distinguish the authenticity of silver by checking the hardness, looking at the stubble, wiping the silver medicine, bending method, and throwing method.

1. Check the hardness: the higher the color of the silverware, the softer the texture, and the more white and smooth the surface. Taking about 60 grams of silverware as an example, if it is opened by hand, there is no hidden power of bullet burial, and its fineness is about 95%.

If it is a little elastic, the fineness is about 80%-90%. If the elasticity is large, the fineness is under 70% of the curved trousers.

2. Look at the stubble: cut or fold the silverware to see the color of the stubble. If the jewelry is soft, the stubble is thick and soft, slightly reddish, and the color of the trembling finch is about 95%.

If it is bent hard by hand, the stubble is white and gray, or slightly reddish, and the color is about 90%. If the hardness is large, the stubble is light red, yellow-white or gray, and the color is about 80%. If it is bent and hard, the stubble is reddish, yellowish, earthy yellow and other colors, and the color is about 70%.

If the stubble lipstick is black in the middle, or yellow in the black, the color is below 60%.

3. Silver medicine wipe test: grind the silver on the touchstone, smear the silver on the silver road with the silver kettan early medicine, hang the silver medicine more into the letter and the color is high, the silver medicine is less The color is low, and the silver medicine is not fake.

4. Bending method: pinch the bending with your fingers, the silver jewelry with high fineness is soft and flexible, easy to bend and not easy to break. The quality is hard, or barely bent, and some cannot even be bent with fingers.

Silver-clad will crack when bent or struck with a hammer. The fake one can't withstand bending and is easy to break.

5. Throwing method: The silver jewelry with high color of pure eggplant is heavy, and the bounce is not high on the plate, and there is a popping sound. Fake or low-quality ones are light, and they bounce very high on the table, and the sound is relatively crisp.

To distinguish the authenticity of silver, you can start from the following aspects:1Chemical Properties:

Silver is a kind of ***, its chemical properties are more stable than the rise and slow, and it is not easy to be oxidized or corroded, so its purity can be tested with carbonic anhydride or sulfuric acid. Real silver will produce a white precipitate under the action of carbonic anhydride or sulfuric acid, while fake silver will not. 2.

Magnetism: Silver is a very weak magnetic material, and testing with a magnet can see some subtle magnetic reactions. Fake silver, on the other hand, does not have this reaction.

3.Scale: Real silver has a relatively high hardness and can be scratched on silver with a knife or other sharp tool.

If it is difficult to make a visible mark, then it can be determined that it is real silver. Fake silver is the opposite. 4.

Color: Sterling silver appears pure white, while fake silver may appear gray or black. 5.

Density: Silver is denser than most common metals, and the density of silver can be measured with a hydrometer. The density of real silver is around 10-11 grams, while fake silver will vary.

6.Gloss: The gloss of real silver is relatively high, you can use a magnifying glass or a microscope to observe the details of the surface of the silver, the surface of the real silver will show a very bright luster after polishing, and the fake silver will have a little rough or uneven surface.
