How to verify the authenticity of silver, and how to distinguish the authenticity of silver

Look at the color, check the hardness, weigh the weight, and listen to the rhyme.

1. Look at the color.

The higher the purity, the whiter the silver, and the surface of the jewelry looks 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.

2. Check the hardness.

**The hardness is lower than copper, and larger than lead and tin, and can be tested in an inconspicuous place where the pin is scratched, if the needle is slippery, 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.

3. Weigh the weight.

**Slightly denser than common metals, generally speaking: "light aluminum, heavy silver, not light and not heavy copper." 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.

4. Listen to the rhyme.

Sterling silver jewelry has a sound on the ground, 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.

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.

1.Look at the color.

Buy silver jewelry. You can observe their color before tasting them. Generally speaking, the color of silver jewelry is silvery, and the higher its purity, the whiter the silver will be. Moreover, under the premise of silver white, the surface of silver jewelry will appear very uniform and not rough.

2.See**.

**of** is about 5 yuan per gram more, this does not add procurement costs, process costs, etc., if ** low outrageously, it must be pure enough or fake.

3.Weigh the weight.

Generally speaking, ** is different from the density of other similar metals, and the density of silver is relatively large in comparison. The density is slightly greater than that of common metals, gram cubic centimeters.

Therefore, the weight can make a preliminary judgment on whether it is **.

4.Look at the logo.

According to national regulations, the silver content of silver jewelry must be accurately marked if your silverware. There is no mark on it, then the item may also be sterling silver itself, simply because it is produced by a country that does not require a mark of purity.

5.Check the hardness.

**The hardness is low, and the silver jewelry is lightly folded by hand, and it is easy to bend and not easy to break. You can prepare a pin, the pin can leave marks on the surface of the silver, but this trace is not obvious, other metals, otherwise there will be no traces, or the traces will be very deep, which can also be used as a basis for identification, but can not be the main basis.

6.Test with acid.

If the acid drips elsewhere, it can affect the luster of the silverware. If you're using a black slate, then a slate. on that imprint - drips acid.

There is also a silver acid detection tool, which is suitable for inspecting sterling silver or alloys, but if you doubt you. If the object is silver-plated, make a mark in the right place to find out what the metal is inside.

1. Throwing method: Throw the silver jewelry from top to bottom on the plate, the bounce is not high, the sound is stable for the silver jewelry with high fineness, and the silver jewelry with high jump and loud sound on the table is fake or low fineness.

2. Distinguish the authenticity of silver by color: the surface of sterling silver looks uniform and shiny with polish. The higher the purity, the whiter the silver.

3. The hardness can also be used to distinguish the authenticity of silver: the hardness is lower than that of copper, and larger than that of lead and tin. It can be tested with a pin-drawn silverware, and it is true if there are traces but not too conspicuous.

4. Weighing is also one of the ways to judge the authenticity: **The density is slightly larger than that of common metals, and the aluminum is light, the silver is heavy, and the copper is not light and heavy.

The identification of silver jewelry mainly includes the following points:

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.

There's also an easy way:

Use hard-boiled eggs to remove the yellow bag silver to blanch the rheumatism, so that if the silver turns black, it is true, and you can also soak it in salt water.

The authenticity of silver can be identified by looking at the color, the silver with high fineness is white, bright and uniform, and the silver with poor color is blue and gray, and the luster is poor.

In addition, silver can also be authenticated by listening to the sound, and the silver with high fineness will make a dull and unrhymed sound, and the silver with a different color will make a crisp sound.

According to the experience of the ancients, there is a good way to identify it, which is to point arsenic trioxide (commonly known as arsenic), and then dissolve the arsenic, and then put the silver in it to see if it will turn black, I think it is a good method! Hey.
