What He Shuangyou took out and put on the table was a small piece, with a five- or six-centimeter-long, three-dimensional round carving.

The carving is a crouched cat, and on top of the cat, there is also a butterfly.

Cat butterfly, take the homonym "耄耋", meaning longevity and wealth.

The jade material is Hetian white jade, slightly shiny blue gray, but the texture is very thick and oily. As far as Hetian jade is concerned, the material that flashes blue or gray often has better density and oiliness, and the whiter the material, the less likely it is to have such a good texture.

That's why sheep fat jade is precious. Because mutton fat jade is not only white, but also top-notch in density and oiliness. At the same time, the white of mutton fat jade is not simply high white, but belongs to the warm white tone.

Nowadays, many merchants will take Qinghai materials or Russian materials with high whiteness and shout mutton fat jade. However, Qinghai materials are generally more "water", the meaning of water is not only transparent, sometimes high-end Qinghai materials are not transparent, but the sense of richness is still the same thing. As for the Russian material, it looks like the density is not small, but it is often relatively "raw", even if it is a high-end Russian material, it looks good at the oiliness, but after playing for a few years, it is difficult to play.

And this "elderly" jade piece is obviously the character of Hetian seed material. Of course, there are also a lot of junk goods in Hetian seeds, but good Hetian seeds can be seen at a glance.

At the same time, the butterfly on the cat's body seems to be skillfully carved with skin color, red and yellow with black spots, bright and beautiful.

"There are so many people who have disputes, how can I eat accurately?" Wu Duoying said, "However, when I see good things, I open my eyes and thank Mr. He first." ”

He Shuangyou smiled lightly and raised his chin slightly, "Let's get started." ”

Wu Duo nodded, picked it up, and first went to see the skin color of the skillfully carved butterfly.

However, upon closer inspection, it turned out that it did not look like a natural skin color.

Looking at the genuine leather and fake leather of Hetian jade, there are two most important points, one is the color root, and the other is the transition color.

The real skin color is colored root. Because the skin color of Hetian seed material is not jade, it is formed by colliding, precipitating and infecting in the river water and riverbed for tens of millions of years.

Transitional colors are better understood, and what has been formed naturally over a long period of time cannot be without layers.

At the same time, the skin color must be formed in the loosest part of the jade, many light white seeds, no skin color, because the jade is very dense, it is difficult to infect the skin color.

And this "butterfly" is more floating, like a skin color.

Wu Duo doesn't need to listen to this, just based on his Hetian jade background, he can roughly judge it.

"Mr. He, looking at this carving style, it should be something from the Ming Dynasty. ”

"That's right. He Shuangyou nodded.

"But this skin color······ Moreover, the jade pieces of the Ming Dynasty rarely have skin. Wu Duo said again.

The skin color of Hetian seed material is now very important to players, but on the ancient jade, there are really not many skins, because the skin color is generally regarded as "impurities", and if you play jade, you must remove the "impurities".

It was not until after the Qianlong Dynasty that there were gradually more things to be carved with skin, but it was also carved according to the needs of the characteristic skin color.

Now, no matter whether the skin looks good or not, as long as it can be kept, I will try to keep it. Because the skin color is the evidence of the seed material, the skin color can be sold at a good price. At the same time, fake skin colors are becoming more and more common.

"It's certainly not a leather color. I can see that, too. He Shuangyou said, "The question is whether it is new or old. ”

Wu Duo was slightly stunned, and then looked at the "butterfly" further, and finally understood that this is oil extraction!

The controversial question is whether it is "old oil".

Lifting oil is a more elegant saying, and many players are commonly known as "fried ghosts".

The method of extracting oil is generally to infiltrate the jade with dyes, and then fry or burn it to make the desired color appear on the jade.

Among them, there is an old oil extraction, also called the ancient method of oil extraction, which roughly began to appear in the Song Dynasty, natural dyes, clever techniques, and good colors do not affect the feel.

To put it bluntly, the old oil and engraving are almost synchronized. What period was an ancient jade carved, and the old oil was made in what period.

Therefore, although the old extract oil is not naturally formed, it is also a way of jade processing in ancient times, and it will not affect the value of a piece of jade.

For example, this "elder" jade carving handle, if it is an old oil in the Ming Dynasty, then it will not affect the value. But if it is a jade carving in the Ming Dynasty, a "new oil" in the Republic of China in the Qing Dynasty or even a fake skin color made in modern times, the value will be greatly discounted.

Wu Duo secretly sighed that his eyesight for the process of oil extraction was not enough, and he quickly listened.

As a result, this is indeed a jade piece of oil from the Ming Dynasty, and there is no problem.

"How is it?" He Shuangyou also asked at this time.

"I think it's the old oil of the Ming Dynasty, no problem. Wu Duo looked at He Shuangyou, "What Teacher He said is controversial, what is it exactly?"

He Shuangyou responded, "I didn't say that modern coloring, the controversy mainly appeared, some people said it was the old oil, some people said it was the new oil in the middle of the Qing Dynasty, because I felt that the color was still relatively floating." ”

"Whether the color floats or not has nothing to do with the dye and the process, and it has nothing to do with the vintage. If it is a new oil extraction in the Qing Dynasty, then the pulp of this 'butterfly' should not be so consistent with that of 'cat'. "Wu Duo is still very good at jade, and knowing that it is an old oil, it is much easier to explain.

"How can you accurately distinguish such subtle differences?"

"Absolutely. The old oil was lost in the late Ming and early Qing dynasties, and then the new oil extraction appeared in the middle of the Qing Dynasty, which was more jerky, even if it was more difficult to identify after the formation of the slurry, but it was not the same, especially the light sense of the slurry, as long as it was carefully compared······ Wu Duo explained further.

After all, He Shuangyou is a person who understands antiques, although he is not skilled in jade, but as soon as Wu Duo said this, he groaned slightly, and then agreed to accept it.

"Admire, admire!" He Shuangyou sighed, "No wonder you are so young that you can be so valued by Mr. Hu!"

"Teacher He's eyesight on agarwood, that's admirable!" Wu Duo hurriedly responded.

"Xiao Wu, don't you know, my lover is in the agarwood business. ”

"Teacher He also doesn't know that I originally studied gems and jade. ”

The two of them couldn't help but laugh at the same time.

After laughing, the distance felt much closer.

"By the way, Mr. He, I just heard you sigh that 'people who don't understand Buddha nature worship Buddha', so you must have studied Buddhism very deeply, right?" Wu Duo suddenly remembered this.

"It's not deep. However, there are many antiques related to religion, and Buddha statues are a big hit in collections, so they have indeed been studied. ”

"Then in our Qizhou, as far as you know, are there any people in the antique shop who are dedicated to Buddha?"
