The material Mr. Wang said was a piece of bloodstone the size of a basketball, which was resting at his feet, and it seemed that it had just been picked out and was being carefully studied.

Wu Chen walked in and saw that there was a palm-sized piece of chicken blood on it, which was extremely red and annoying, and it looked like it was worth a lot!

"Not bad." He casually perfunctory, squatted down, and stroked it with his hand, it was cold, and it felt good.

"Hehe, I suspect this might be fake." Mr. Wang was direct, and after squatting down, he said in Wu Chen's ear, his voice was like a mosquito, but his tone was a little affirmative.

"Won't it?" Wu Chen was taken aback by Mr. Wang's words, in this world, there must be fakes in bloodstone, especially in the hawker stalls on the street, those low-priced bloodstone seals are almost all fakes.

Counterfeiting and identification have always complemented each other, and it can be said that without falsification, there is no identification.

Although bloodstone is used as a "queen of seals", the time when it began to become popular on a large scale is much shorter than the time when Guigu will appear, therefore, there is no such record in the early Guigu Society, and in the continuous expansion of later generations, because it is a small item, it is relatively little contained in the "Treasure Road", but because Liu Lao's own preferences for seals, especially for Tian Huang and Ji Xue, the emperor and queen, are studied very thoroughly, so when Wu Chen studied with him, he was about the forgery and identification of bloodstone. It's also an important point.

Bloodstone, regardless of the texture, "blood" is the main object of counterfeiting, so dyeing the stone is the sect that never leaves its sect in the counterfeiting of bloodstone.

The most common method is to select some places on the surface of the stone, dig small pits of different depths, and then embed them with red mercury sulfide paint, let them dry naturally, and then polish and wax.

This so-called "embedding method" is the most untechnical, simple and crude, but the effect is not bad, fooling ordinary people, there is no problem at all, mainly because mercury sulfide is the same thing as cinnabar, and now it is just "artificially added".

It can be said that most of the so-called "bloodstones" on the market, especially in the streets and alleys, which cost hundreds or thousands of yuan and look red, come from this way.

However, there is a problem with this method, that is, there is no layer, like wall paint, it looks too flat and stiff. For people who are often exposed to bloodstone, it is not too difficult to identify.

The more complicated practice in the industry is to apply mercury sulfide to the stone, dry it in the shade, and then dry it in the shade...... This process is like brushing N times more when brushing, which makes it appear slightly layered, and where the paint is in contact with the stone, there will be a phenomenon of "dipping", and this degree of fusion will really cause the difficulty of identification.

After this, the whole stone is soaked in transparent resin, picked up and dried, and then polished with fine water and sand. This method is made, after carving, and placed in various "counters" in a grand manner, and sold as a mid-range material, which can already deceive ordinary industry insiders.

Fake bloodstone made in this way relies on the resin on the outside to "cover" the bright "blood" inside, but because the resin is easy to age, after being placed for a long time, the epidermis will show signs of yellowing and become less "transparent", which will lead to the degradation of the "blood color" and look incongruous. In addition, because the pores of the resin epidermis are thick, if you look closely with a magnifying glass, there are a few small potholes on the surface.

In addition, there are also slices directly attached to the bloodstone seal. There are also mercury sulfide added to real bloodstone, and a very thin layer of resin is covered with the surface of the added part.

All of this, to name a few, there are both completely fake, there are also true and false, false and true, if it is a few hundred yuan, everyone knows that it is a fake, then it doesn't matter. But if it is high-end, it can be complicated to identify.

But the stone in front of him, if you want to say that it is fake, Wu Chen really didn't see it at a glance.

After he took the strong flashlight and magnifying glass handed by Mr. Wang, he leaned on the stone, his eyes were almost attached to the magnifying glass, in the eyes of outsiders, this action was decent, that is, he was using the magnifying glass to observe the direction of the chicken blood lines on the stone.

In fact, Wu Chen directly spread the cheat, his eyes passed through the magnifying glass, and penetrated into the interior of the stone, and for a while, it seemed that there were not too many traces of fraud.

He looked at it from the palm-sized piece of chicken blood, and when his eyes first came into contact with the piece of chicken blood, he had a familiar feeling, not much different from the "blood" he had just seen, at least this small piece of chicken blood was real. It's just that the extent of this piece of "blood" is not deep, less than a finger, and inside, it is some ordinary stone meat.

Such a stone should be decomposed out, and the bloody part will be "dug out" as a seal or small ornament, with this palm-sized piece of blood, the blood color is not pure enough, there are broken lines, and the texture is average, and it is only about 100,000.

However, if it was said to be a fraud, Wu Chen didn't see anything wrong. Wu Chen turned off the strong flashlight, returned it to Mr. Wang, and shook his head slightly, indicating that he didn't see it well.

Mr. Wang's expression was obviously relaxed, he was consciously testing this new "Jade King" who was rumored to be mysterious, and now it seems that his skills on bloodstone are only average.

As an old businessman who has been rooted in this line for a long time, he knows that this industry has always been not afraid of money, nor is he afraid of technology, he is afraid of both money and technology.

"Are you looking here......" Mr. Wang used the iron edge of the magnifying glass to gently tap the side of the bloodstone, on this side, there are a few finger-thick blood lines, it seems, far brighter than the slap just now, because of the squatting down, Wu Chen didn't notice it just now.

Wu Chen moved, and at first glance, he felt that the value of this color was much higher than that one just now, and the shape was a bit like chrysanthemum petals, and the rhythm of flowering in the middle, judging from the change in thickness, was easily reminiscent of the thickness of its penetration under the stone.

Could it be that this side is the real value of this stone?

The moment Wu Chen's eyes penetrated, that feeling was a little wrong, there was a layer of oil on the epidermis, but based on this alone, it was impossible to conclude that it was a fraud, after all, many people now polish and wax for the sake of the good looks of the stone, which is a bit like a car after waxing, it will be more glamorous, in essence, this kind of practice that does not change the physical structure or chemical structure inside, but only makes the appearance more beautiful, is not considered a fraud.

At best, there is still an essential difference between putting on light makeup, following a knife, an injection, or filling in silicone.

However, as his eyes went deeper, his heart was full of horror, this piece of material was really passive!
