How to identify silver??? Urgent, thank you!

It's not that it's white, but that there's no other variegated color after it's red.

Let's introduce you to a few simple methods.

1. Color identification method: Observe with your eyes, look white, shiny, fine workmanship, and print the store number on the jewelry, which is silver jewelry with high fineness; Poor color, poor color and luster, and dull are mostly fake silver jewelry.

2. Bending method: fold silver jewelry lightly by hand, easy to bend and not easy to break; stiff, barely folded with lower fineness; After bending or cracking with a hammer, it will crack for silver-clad jewelry; Those that can't stand light folding, and are easy to break, are fakes.

3. Throwing method: throw the silver jewelry on the table from top to bottom, and the silver jewelry with high color and low bounce and stable sound is high; Thrown on the table and jumping higher, loud, fake or low-quality silver jewelry.

4. Nitric acid identification method: use a glass rod to drop nitric acid on the file of silver jewelry, which is brown beige and slightly green. It is dark green and has a low color of black. "Plain silver, Thai silver, Tibetan silver" noun answer Thai silver, also known as "black silver", is to melt a mixture of silver and sulfur on silver jewelry and form a covering layer in a vitreous state.

The black silver overlay is loose and jet black, which contrasts sharply with the smooth silver white of **, producing a special visual effect. Due to the special anti-aging treatment, the black silver jewelry not only does not change color for a long time, but also greatly enhances the surface hardness. The unique texture and color make this jewelry rugged and quaint.

1) Imprints. Silver jewellery should generally be marked with the abbreviation "S" or "sterling" for silver. The mark of standard silver is S925. The seal of pure silver is S990. However, there are many countries that do not have a mark on silver jewelry.

2) Color. Silver jewelry is mostly silvery-white with a slight yellowish tinge, with a soft metallic luster. Because it is easy to oxidize, the color will turn dark yellowish-white over time.

3) Weighting. The density of silver is grams of cubic centimeters. Smaller than platinum, **, no drop feel with your hand. The steel needle can be scratched and bent. In this way, it can be distinguished from German silver jewelry with platinum main, karat white gold or imitation silver.

4) Acid test. Silver can change color and even dissolve when exposed to any acid. If a drop of concentrated hydrochloric acid is placed on the inside of the silver jewelry, a white moss-like silver chloride precipitate is immediately formed. This is not the case with other ***.

5) Phonology. Standard silver jewelry has a dull sound after it lands, does not bounce, does not roll.

925 silver (plain silver) silver + copper alloy, is an internationally recognized standard of pure silver, usually plated with white gold (rhodium) to prevent yellowing and blackening due to oxidation or vulcanization, and 925 silver without platinum plating is called "plain silver". (In order to distinguish it from the inlay category, the electroplated platinum is also placed in the plain silver category) Tibetan silver generally does not contain silver, is the elegant name of white copper (copper-nickel alloy), the traditional Tibetan silver is 30% silver + 70% copper, because the silver content is too low, so now it is no longer seen on the market, has been replaced by white copper.

Buy a bottle of pesticide and see if it will turn black.

I think everyone is familiar with it. In ancient China, we used silver as currency. When it comes to **, the first thing that comes to mind is silver jewelry.

Silver jewelry is common in life, including earrings, rings, necklaces, etc. With ** being sought after by the public, there is a huge amount of dazzling silver jewelry on the market. **Although it is not valuable, it can be true and fake.

How to identify ** is particularly important. **There are three types of identification: marking, color, and weight.

Silver jewelry is usually marked with the English abbreviation of silver. As a modern modern student, the English abbreviation should be familiar, which is "S" or "Sterling". Standard silver seal S925, full silver seal S990.

The English abbreviation of silver, will be hit into silver jewelry. As far as bracelets are concerned, when buying silver bracelets, you can look to see if the inside of the bracelet is engraved with the full abbreviation of small s or silver. If there is, then it should be true.

But there are many fakes in real life, and there will be marks on the inside of the bracelet, so this method cannot be used as a reference. And now many countries don't print banknotes on silver jewelry, so we don't have to worry so much about that. However, there will generally be an appraisal certificate, and silver jewelry will be carried with you when you buy it.

Second, look at the color. Silver and gold are different. Slightly yellowish, i.e. silvery-white, with a softer metallic sheen overall.

But now there are a lot of counterfeit and shoddy products with silver powder paint on the market, and many people will be deceived just by looking at their appearance. In addition, silver is susceptible to oxidation. Over time, its soft silvery-white metallic luster will gradually turn dull yellowish-white.

Then there are two ways to judge, one is the combustion method. If it's true, the color won't change after being roasted over fire. However, if it is fake silver or other inferior products, it will turn black after being roasted by fire.

If you really want to distinguish the authenticity of **, you can try this method, but many people may feel distressed. Finally, there is the weight. The density of silver is grams per cubic centimeter, which is smaller than platinum and gold.

If you weigh it with your hands, it doesn't feel like it's falling. You can use a silver needle to make a mark on the silver and bend it. If you really want to judge by weight, you can keep a small scale at home.

In addition, there are many types of silver now, and the weight of different silver is not the same, so if you want to buy silver jewelry, you must see clearly the density and weight of this silver.

Simple methods for identifying silver include markings, magnetic tests, chemical tests, bending tests, and reflective tests.

1. Look at the mark.

The real one will be engraved with the "925" or "S925" logo on the surface, which is also an important sign to distinguish the real and fake silver loss.

2. Magnetic test.

Silver is a non-magnetic metal, so a magnetic test can be used to determine the authenticity of silver jewelry. Place the silver jewelry on the magnet, and if the silver jewelry is not attracted to the magnet, then it can be considered to be real silver.

3. Chemical testing.

Silver jewelry can be tested for its composition by performing a chemical test. A small amount of nitric acid is dropped on the silver jewelry, if the silver jewelry turns white, then the pin is real silver, if there is no reaction or turns black, then the core can only be fake silver.

4. Bending test.

Silver is relatively soft, so the authenticity of silver jewelry can be judged by a bend test. Real silver jewelry can not break easily in the case of constant bending, whereas fake silver jewelry is prone to breaking.

5. Reflective test.

Real silver jewelry has a strong reflection, you can observe the reflection of silver jewelry in the sun, if the reflection is strong, then it is likely to be real silver.

The identification method of silver is as follows:

1. Look at the logo and color: each silver jewelry will have a purity logo and manufacturer logo, such as S925 is a sterling silver platinum, the color is brighter than the plain silver of S990, and the color of S990 sterling silver is slightly lower in gloss, and the color is white and yellowish.

2. Sound judgment: you can throw the silver jewelry gently, watch its bounce and listen to its sound. Sterling silver jewelry will not bounce, the sound is low, if it is silver-plated white copper, the sound is very sharp and loud, it can be judged as fake silver jewelry.

3. Color judgment: after the fire barbecue, if it is true, the silver will not change; If it is fake**, or the color is inferior, it will turn black after grilling. Another method is to use nitric acid to drop on the surface of silver jewelry, after wiping nitric acid, the surface of the jewelry is still silvery-white, which indicates that the silver content is quite high, if the silver content is low, it will be gray-black.

4. Bending method: bend with both hands, high fineness, easy to bend and not easy to break, quality bending is harder, or barely folded, some can not even be bent with fingers, the silver-clad will crack after bending or knocking with a hammer a few times, and the fake one can not withstand bending, easy to break.

5. Check the hardness: **The hardness is lower than copper, and larger than lead and tin, you can use a pin to scratch the inconspicuous place of the jewelry for testing, if the needle is slippery, it is difficult to leave traces, it can be judged as copper jewelry.

There are several ways to identify silver: visual inspection: silver has a silvery-white luster, and it is relatively soft, you can use your fingernails to gently scrape it to shout Yuyu, if there is silver shavings falling, it is likely to be silver.

Magnetic test method: silver is a non-magnetic rolling material, which can be dismantled and adsorbed with a magnet, if there is no adsorption, it is likely to be a silver product. Density test method:

Silver has a density of and can be tested with a density meter, and if the density is close, it is most likely silver. Chemical test method: It can be tested with nitric acid, a small amount of nitric acid is dropped on a silver product, if white gas appears, it is likely to be a silver product.

It should be noted that the above methods are only preliminary identification methods, if more accurate identification is required, you need to use professional testing instruments and equipment, or ask professionals to identify.

The easiest way to identify silver: look at the color, look at the hardness, burn, look at the specific weight, look at the marking.

1. Look at the color.

The higher the fineness of the silver, the surface presents a bright white metallic luster, which looks like a kind of polish and is not easy to fade, while the surface of the fake silver is darker and has no luster, which looks dull and stiff.

2. Hardness. The higher the silver content, the softer the texture and easy to deform, so it is easy to avoid contact with hard objects in ordinary times, and it is easy to have obvious marks when biting with teeth, while fake silver has low fineness, high hardness, and is not easy to deform.

3. Fire. Sterling silver will generally turn white after being burned by fire, and will not turn black, if it is burned black, it means that it is not sterling silver. Burning silver with a lighter may turn the silver black, but a brush of toothpaste can turn white again. As long as the cavity can be burned black, it is basically not sterling silver.

4. Specific gravity. Generally speaking, the density of real silver is high, the proportion is heavy, and it has an obvious pressure feeling when it is placed in the number of yards in the hand, while the silver content of fake silver is not high, the density is low, the specific gravity is small, and the pressure feel is not obvious when it is placed in the hand.

5. Marking. According to the relevant international regulations, the general ** silver jewelry will be marked with imprints, such as S925, AG925, S990, AG990, and fake silver jewelry is usually not, so that it can be better distinguished.

1. Look at the color.

There is a mantra called "seven greens, eight blacks, nine five whites". The higher the purity, the whiter the silver, and the surface of the jewelry should look evenly 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.

Silver jewelry is mostly silvery-white with a slight yellowish tinge, with a soft metallic luster. Because silver is easy to oxidize, over time, the color will turn dark yellowish-white. In short, silver jewelry that looks white, shiny, finely made and has the store number printed on the jewelry is a high-quality silver jewelry; It looks yellowish in color, has rough workmanship, and is a silver jewelry with low fineness; The color is poor and the matte is mostly fake silver jewelry.

2. Weigh the weight.

**The density is slightly larger than that of common metals, but it is smaller than that of white gold and **, so that there is no heavy feeling of falling hands with your hands. Generally speaking, "aluminum is light, silver is heavy, copper is not light and not heavy", so the weight can be made 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 can be tested in inconspicuous places where the pin scratches the jewelry, 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. Steel needles can be scratched on silverware and can also be bent. Bend silver jewelry by hand, which is easy to bend and not easy to break; stiff, or barely folded, and some even unable to fold with their fingers; After bending or cracking with a hammer, it will crack for silver-clad jewelry; It is not easy to bend, and it is easy to break, it is a fake.

In this way, it is possible to distinguish jewelry in platinum, white gold or imitation silver.

4. Listen to the rhyme.

Silver jewelry that is thrown from top to bottom on the table, does not bounce high, and has a "porphyry" sound is real or high-quality silver jewelry. Sterling silver jewelry is loud and non-elastic; Silver jewelry that jumps high on the table and has a high-pitched voice is a fake or low-quality silver jewelry. The lower the color, the sharper, higher and higher the voice; 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. Test acidity.

Silver can change color and even dissolve when exposed to any acid. If a drop of concentrated hydrochloric acid is dropped on the inside of silver jewelry, a white moss-like silver chloride precipitate will be immediately generated, while other *** do not. Use a glass rod to drop nitric acid on the file of silver jewelry, which is brown rice, stable green or Hui green with higher fineness; It is dark green or even black, and the color is lower without foam or foam at the file.

The silver jewelry is ground out of the silver road on the touchstone, and the silver medicine (the silver medicine is a soft body formed by the mixture of more than 95% of the color of the ** surface and mercury) on the silver road.
