Hearing what Xiao Yun said, the stall owner's face fell instantly, and he said displeasedly: "Young man, what you said is not very kind. Didn't you hire a jade appraiser? Didn't I

'Rogue window', can he not see it?"

Xiao Dahai raised his head proudly and said, "Yes, I just looked at it. The window opened by this stone must be fine."

The "rogue window" as many people call it is a cheating method commonly used by some businesses, and it is generally divided into many types.

The first is to open the window without polishing and do frosting treatment, that is, to open a large window. However, the jade meat is not directly polished flat, but is artificially polished with a drill to create various textures, making the surface of the jade meat appear uneven, like

Fish scales, like the texture of natural stone.

This kind of window is generally called a fish scale window. Its advantage is that it can hide floc cracks and a part of the cotton. After lighting, it will cause a visual error due to the different refraction angles.

Businessmen usually also apply oil on the windows. Applying oil can improve the gloss of the windows and make people feel like they are made of old stone.

However, the fish scale window is only an entry-level rogue window. If this was the case, Xiao Dahai would have noticed it long ago. Would it be Xiao Yun's turn to remind him?

The second type is to open multiple small concentrated windows with multiple windows. This kind of window is also called a leprosy window.

In fact, if you think about it carefully, you can notice something is wrong.

After all, a good window can be cut open with a single knife, but why do merchants have to spend so much effort to open it to make it look like a toad?

In fact, it’s just to hide the cotton and dirt at the incision!

Those sunken areas are usually due to removal of cotton and dirt, which are difficult to detect with the naked eye, and lighting is even more deceptive.

There is another type called spider window. There are two types of spider windows, one is like a spider web and the other is like a spider's legs.

This kind of window is mainly used to hide cracks. Generally, there is no opening between the windows. Ninety-nine percent of them have cracks, no doubt!

However, none of these three common rogue window conditions appeared on this rough stone. Xiao Dahai was very sure, after all, he had observed it carefully just now.

When Xiao Yun said this, wasn't he trying to undermine him and go against him?

"Mr. Xiao, don't just learn how to look at stones and just give random advice here. There is definitely no problem with this piece of jadeite material with a window opening. The meat is already visible at the window opening. No matter what happens later, it can be done.

Something!”

Xiao Dahai's tone at this time was already somewhat tit for tat.

However, window opening material is also a kind of jade gambling stone. Whenever the word "gambling" is involved, you must be rational, you must restrain yourself, you must not make impulsive purchases, and you must accumulate your relevant knowledge to a certain degree.

Only when you are ready can you start.

Xiao Yun glanced at him lightly and said: "Although the materials with windows open seem to be more reliable than those without windows, if you want to see the quality of jade through the window, you must not only have rich experience, but also need

Some luck."

"If nothing else, if a piece of material has a window and performs very well, then why doesn't the boss just cut it and sell it to you so that you can make money?"

Upon hearing this, several people's faces were slightly startled.

Yes, the boss is not stupid!

If he liked this piece of material, would he sell it to them?
