Revealing the authenticity identification methods of jadeite passed down by merchants, which are either outdated or invalid

The topic we are going to talk about today is probably a cliché in the eyes of many jade lovers.

It is precisely this method of identifying the authenticity of jade that many people are talking about on the Internet, but there is still an endless stream of people being deceived by it.

It's very simple. The counterfeiting technology is constantly improving. Many of the original identification methods have been eliminated early on, or some identification methods are simply wrong.

Unfortunately, there are still many jade lovers who are still using these methods, so there is definitely no way to identify the authenticity of jade.

Today, I will talk to you about those invalid jade authenticity identification methods that we should no longer use.

1. Water drop identification method: When water is dropped onto jadeite, real jadeite will be in the shape of round water drops, while fake jadeite will not.

This identification method is rarely used. Only when newcomers go to the counter to buy jadeite, the merchant may see that you are a newbie, so he will use this method to fool you.

Although this method is no longer useful now, it was effective a long time ago.

This identification method utilizes the tension phenomenon that exists on the smooth surface of jadeite. In other words, this phenomenon will occur on any sufficiently smooth curved surface.

Therefore, this is a one-sided identification method, because in the early days, the production technology of B-grade jade was very backward. There would be net patterns and pits formed by acid etching on the surface, and water drops would not form round beads.

This has led jade lovers to have a wrong understanding that jade that cannot form water droplets is fake, but they ignore the fact that jade that has water droplets is not necessarily authentic.

Especially today, the counterfeiting technology of jade has become very advanced. The finished fakes must also be polished and waxed. There is no difference between the surface and the real ones, and water drops on them are exactly the same.

This method of identification has long been invalid.

2. Identification method by scratching glass: Jadeite that can scratch glass is fake jade.

This method of identification is pure nonsense.

This is an identification method used by merchants to deceive jade lovers into buying low-grade jade. In fact, it is the same method as the kitchen knives sold today that can slice large bones.

Jade is indeed very hard, and scratching glass hard will indeed leave marks. In fact, not to mention jade, many stones can leave marks on glass.

Of course, there is a prerequisite, you have to use all your strength and be willing to damage your jade.

The essence of glass is quartz, and its hardness is close to 7. Although the hardness of jade is slightly greater than that of glass, the most seriously injured thing when scratching glass is not the glass, but the jade.

Because glass has undergone chemical treatment, its hardness is uniform everywhere, while the hardness of each part of natural jade is different. Some places are harder than glass, while some are not as hard as glass.

3. Identification method by feeling: Jade feels cool to the touch.

Some merchants claim that jade that feels cooler is real jade, which is another nonsense identification method.

The temperature of most natural jade is affected by the external temperature. As long as it is lower than the temperature of the human body, it will feel cool.

Put the jade in a high temperature place in summer for a while, then touch it to see whether it is cool or hot.

This statement has no scientific basis.

4. Identification method by knocking: Jadeite has a crisp sound .

This method has been mentioned many times. It is also very unreliable. There are many things that make crisp sounds when knocked, not just jade.

There is nothing wrong with jade making a crisp sound when you knock on it, provided that the jade has no cracks. If there are cracks, the sound will still be dull.

What's more, today's fake jade has undergone chemical processing, and the sound you make when knocked is no worse than natural jade.

The principle will not be explained in detail.

5. Burning method: Wrap your hair around jade and burn it with fire. If it breaks, it is fake.

You can just try this method yourself, it's pure nonsense.

The merchant tells you that jade has good thermal conductivity, so it will not burn your hair. This makes no sense.

Even primary school students know that fire is divided into inner flame and outer flame, and the temperature is lower inside and higher outside.

Try burning it with an external flame. Unless it is steel wire, not hair, you will know for yourself if you try it.

The current methods of jade counterfeiting are very advanced. The most reliable way is to go to a specialized appraisal agency for appraisal.

Or just find a reliable and reputable merchant to buy it from. Don't be greedy for bargains. Many stores have similar prices. Suddenly, you find a store with products that look similar but are much cheaper. It's best not to think about getting a bargain. If you buy something, you'll probably be cheated.
