Teach you how to distinguish B and C grade jadeite

I have summarized three ways to identify whether jade has been processed with the naked eye, and now I will teach you.

The first sign that can be used to identify with the naked eye whether the jade has been processed is this: we have mentioned before that B-grade jade is bleached and injected with glue, so the jade that has been bleached and injected with glue contains glue.

So there will be a phenomenon that when you hold the jade in your hand and look at it, you will find that its surface is full of waxy luster.

Untreated natural jade has a glassy luster. If it is treated with glue injection, it will emit a foggy waxy luster. This is a point of knowledge for identification.

The second way to identify with the naked eye is this. As I just said, our B-grade goods will be bleached and dyed, so there is a process of immersing them in strong acid.

To destroy the original structure of jade and make it looser. So when you have undergone the destructive treatment, we take any jade product in our hands and look at the surface of the jade through reflected light at a 45-degree angle.

When you look at this layer of the epidermis, you will find a lot of bumpy spots caused by strong acid treatment. When we look at the surface through reflected light, we can see there are many spots.

Some students may ask, Teacher Zhang, what exactly does this point look like? I have no idea what it means.

Let me tell you the simplest concept. I think everyone has eaten oranges, right? So the surface of oranges is actually called orange peel texture.

This pattern is the same as the dots you see when the surface of processed jade reflects light. It is very dense and has many small potholes. This is also a point of identification.

These two methods of identification by naked eye are both from when we discovered problems and loopholes in the process of counterfeiting B-goods. We use these two (methods) to identify with the naked eye.

The third method of identification is what we call C goods, because C goods are dyed. The dyeing process is done on the jade. I have told you before that there are several ways of dyeing.

One way is to immerse the entire jade in the pigment, and the result will be full color. However, because of the waxy texture I just mentioned, the surface (orange peel texture) can be used to judge.

If you get the kind that is not completely soaked, but is painted on the jade with a brush, piece by piece and thread by thread of green, there is actually an identification point that you can discover.

First, these colors float on the surface of jade. Why? He had no way of letting its color penetrate deeply into the interior of the jade.

Secondly, you cannot see the color roots in these colors. What is the concept of color roots?

When we look at natural jade, its green color will be like this, radiating out like a root and then slowly spreading out. There will be a very dense, relatively dense, and thin line, which we commonly call a color root.

But think about it, will color roots appear when dyeing? It will not appear either. So these are the three types I just talked about.

One is a waxy luster, one is orange peel texture, and the third is that the color floats on the surface with no color roots. These three methods can be used to identify counterfeit jadeite as long as you practice more and observe more.

Finally, let me make a brief summary. The key point of practical and applied jade studies is that when we study all aspects of jade, we are not like traditional training institutions. We will extract experiences that are truly useful in the market, and they are summarized after practical experience.
