When I bought a silver cup when traveling, how to identify whether the cup is pure silver?

Introduction: It's the annual summer vacation again, and children and parents are very happy to travel. There will also be a variety of special goods that attract attention during the tour, among which silver cups are very common and the price is not very high.

Everyone is curious about whether it is real sterling silver, and let's tell you how to identify whether the cup is sterling silver.

1. The magnet identification method tells you that real sterling silver is not magnetic, so if you want to know whether the silver cup you bought during the trip is pure silver, you can take a magnet and put it on the inner wall of the cup. If this magnet is attached, then this cup is a fake, and if the magnet immediately slides to the bottom of the cup, then this cup is sterling silver. Let me tell you again, most of the fake silver cups are made of electroplating of other metals, which are magnetic.

Second, the thermal conductivity method to identify sterling silver is very good, so you can pour a little boiling water into the bottom of the cup, and then touch the mouth of the cup with the palm of your hand. If it feels very hot, it means that the cup has a high silver content, and it may also be pure silver. It is not a silver-plated product, which takes advantage of the rapid thermal conductivity of silver.

The inner liner of a real sterling silver cup has a bit of a frosted feeling, because even after a lot of polishing and polishing, it has a certain roughness.

Target. On the contrary, the surface of the electroplated silver product is very smooth, you can touch the inner wall of the silver cup with your hands, if it is very smooth, it is a fake. Finally, whisper that silver-plated cups are very harmful to the human body, so you must identify them well.

3. Experimental identification of bleachIt is known from professionals that silver is the most reactive of all metals and most easily reacts with oxygen in the air to turn black or brown. Oxidation of bleach in life.

It is so strong that we can put a small drop of bleach on the inner wall of the silver cup and then carefully observe the changes in the surface of the inner wall. If the inner wall immediately darkens or blackens, it means that the purity of this silver cup is very high, and it may also be a sterling silver cup.

Real silver is still very soft, you can see if you can bite it, and the imprinted cup means that it is pure silver.

To see if the silver cup will rust, to see how the plasticity of the silver cup is to see the hardness of the silver cup, if you can't identify, you can also take this cup to the place where the silver jewelry is sold, let the teller help you identify.

You can go to the relevant place to identify, or you can identify it through small methods or tricks, and you can use the gloss. Color. and thickness to measure.

Summary. 1. Thermal conductivity: Because the thermal conductivity of silver is very strong, we can pour a little boiling water at the bottom of the silver cup, and then touch the silver part of the cup with our hands, if you immediately feel hot, you can be sure that the purity of the silver content of this cup is at least 80 or more, and it will not be a silver-plated product.

2. Bleach experiment method: the bleach is extremely oxidative, drop a drop of bleach on the inner tank of the silver cup. Carefully observe the changes on the surface of the silver liner.

If the silver liner is immediately darkened or darkened, the purity of the silverware is higher. 3. Magnet identification method: only a magnet needs to be placed on the inner wall of the silver cup, and the feeling of magnetism is fake, and the non-magnetic is real!

Because real sterling silver does not form a magnetic field. On the contrary, most of the fake cups are made of stainless steel + electroplating, so they are magnetic! 4. Listen to the sound:

Take a one-dollar coin and put it in the cup, and listen to the sound: if the sound is low, humming, and not loud, it can basically be judged to be pure silver; On the contrary, if it is clear and green, it is a silver-plated cup that is loud.

Hello dear, I am happy to answer this question for you, the easiest way to identify the silver cup: put fresh orange juice, soup or milk in the cup, place it for 1 2 days, the real silver cup in the Pai Yun Hui tea soup or quietly take milk and other drinks will not deteriorate, because the silver cup has a sterilizing effect, and the water and milk can be put for a long time without attacking mold, fermentation, and smelling.

Fake silver cups are generally silver-plated with white copper. The Yin Yun real sterling silver cup Mu Jianzi's Xun Xiang Chong inner tank looks smooth, like a bowl, while the fake cup will leave a circle of lines on the inner tank because of the silver plating, like a steel wool ball rubbing.

There are also real sterling silver cups that will be marked with S999 or AG999 on the cup rock sparrow, which represents a thousand feet of silver, and the withered and silver-plated will only mark a silver.

The thermal conductivity of boiling water test silver is far better than that of stainless steel, so drinking water at the thread of the cup mouth with a sterling silver cup will be hotter than cups of other materials, while silver-plated cups and stainless steel cups will not have a difference!

There are also the following ways to identify!

1. Thermal conductivity: Because the thermal conductivity of silver is very strong, we can pour a little boiling water at the bottom of the silver cup, and then touch the silver part of the cup with our hands, if you immediately feel hot, you can be sure that the purity of the silver content of this cup is at least 80 or more, and it will not be a silver-plated product. 2. Bleach experimental method:

The bleach is extremely oxidizing, so put a drop of bleach on the inner liner of the silver cup. Carefully observe the changes on the surface of the silver liner. If the silver liner is immediately darkened or darkened, the purity of the silverware is higher.

3. Magnet identification method: only need a slippery block magnet to be placed on the inner wall of the silver cup, and the feeling of magnetism is fake, and the non-magnetic is real! Because the sterling silver of Zhenxin Pei Tong is not a magnetic field.

On the contrary, most of the fake cups are made of stainless steel + electroplating, so they are magnetic! 4. Listen to the sound: Take a one-yuan coin and put it in the cup and listen to the sound

If the sound is low, humming, and not loud, it can be judged to be pure silver; On the contrary, if it is clear and green, it is a silver-plated cup that is loud.

The benefits of drinking water from a silver cup are that it can help wound healing, prevent infection, purify water and preserve water, etc. The disadvantage is that it is easy to produce heavy metal poisoning. Silver is an inert metal that holds food, preserves freshness, and prevents bacteria from growing.

Traditional Chinese medicine believes that psoriasis has"Settle the five treasures, calm the mind, stop palpitations, and get rid of evil spirits"role. Injecting silver nitrate solution with a concentration of 1% into the eye of neonates can effectively prevent neonatal conjunctivitis and reduce the blindness rate of neonatal conjunctivitis. Moreover, silver has a killing effect on microorganisms.

The silver thermos flask is indeed a very beautiful one, my mother has a silver thermos flask, the silver thermos flask, it has a health care function, it can remove the moisture of the human body, this is a health care effect, in addition, his bad thing is that it is not easy to clean, useful, can detoxify and nourish the skin, it is best to drink water with a silver cup. Silver is said to be good for detoxification and beauty, whether it is wearing silver jewelry or drinking water from a silver cup, it is good for the body. The silver cup is high-end and high-grade, so that others feel very dazzling when they see it.

When receiving important customers or VIPs, it is an attentive machine that makes customers feel that you are more attentive.

Purifying water quality is one of the important benefits of people drinking water with silver cups, because the silver ions in silver cups can destroy various bacteria and harmful substances in the water, can prevent them from breeding and multiplying in the water, and play an important role in purification, people will be safe after drinking water, and it is also very good for healthy health. If the silver dissolves or reacts with the liquid in the cup, it will cause heavy metal poisoning and affect health. In daily life, it is not necessary to pursue a silver cup to drink water.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

First of all, when buying a sterling silver cup, you must first pay attention to the workmanship of the cup, the material of the cup, the purity and weight of the sterling silver liner, and the volume of the cup, so the most important thing is whether the inner liner of the silver cup is a sterling silver liner, so the method of judging the sterling silver liner is as follows:

1. Real sterling silver cups will be marked with S999 or AG999 on the body of the cup, which represents a thousand feet of silver, while silver plating will only mark one silver.

2. The inner liner of a real sterling silver cup looks smooth, like a bowl, while the fake cup will leave a circle of lines on the inner cup because of the silver plating, like a steel wool ball rubbing over.

3. The real sterling silver cup has a preservation function, pour a glass of milk, it will not swish for two days, and the inner wall will not rust, while the silver-plated cup is really good opposite.

4. Let's see if the certificate of the silver cup can be checked on the official website of the country.

One is to pour a little boiling water at the bottom of the cup, and then touch the top of the silver liner with your hands, if you can quickly feel hot, then the silver cup contains at least 90 or more purity, because the thermal conductivity of silver is too high, which can distinguish whether the liner is silver-plated.

The second is to experiment with magnets, magnets do not absorb pure silver, if they are made of other metals or doped with other metals, they will be attracted to magnets.

The third is the nitric acid identification method: use a glass rod to drop nitric acid on the surface of the sterling silver health care cup, the color is beige, slightly green, it proves that the purity of the silver is higher, and the dark green and black prove that the purity of the silver is low.

Fourth, the identification certificate identification method: the sterling silver health cup belongs to the best products, and the sales of regular manufacturers or regular merchants will be matched with the gold and silver identification certificate issued by the qualification agency. You can ask the merchant at the time of purchase.

There are many benefits of drinking water with a silver cup, the first is disinfection and sterilization, when the silver cup is filled with water, a trace amount of silver ions will dissolve into the water and kill bacteria; The second is to purify water quality, and silver ions have the effect of improving water quality; The third is detoxification and beauty, silver ions can accelerate the speed of blood travel and promote the body's metabolism.

Drinking water from a silver cup can effectively destroy the bacteria in it, enhance immunity, promote the digestion and absorption of gastrointestinal peristalsis, and silver can accelerate wound healing and prevent wound infection. Silver and gold are inert metals, and they will not react when they are released with water, but be careful that metal powder falls into it, and metal powder will cause heavy metal damage to the human body, so be careful.

The benefits of drinking water from a silver cup can help wound healing, and the silver ions in it will be released, which can play a role in sterilization, inhibit the reproduction of bacteria, and purify water quality.
