Meng Zitao gave this jade carving to He Wanyi who was standing next to him, and then said: "The author of this jade carving is of a very high level, I guess he is at the level of a master."
"Ah, is it that high?" Lao Bian was startled.
After He Wanyi had seen it, Song Xiaofeng also appreciated it, nodded and said: "The level is indeed very high, but it's a pity that this is a Dushan jade carving. If the Khotan jade is used, it can cost tens of thousands, and the seed material will be even more It¡¯s hard to say.¡±
The old man smacked his lips. He thought this jade was quite good before, but because of the material, he never took it seriously. He didn't expect the author to be of such a high standard and of such great value.
Seeing Lao Bian¡¯s slightly regretful expression, Meng Zitao smiled and said, ¡°Boss Bian, I still like this jade, but there¡¯s no need to give it to me. Just give it to me for a thousand yuan, how about it?¡±
The old man quickly waved his hand and said no, he is also a face-seeking person, and he still needs money for the things he gives away, and he can't get along without talking about face.
However, Meng Zitao still took out a thousand yuan and handed it to Lao Bian.
Song Xiaofeng took the cheerful old Bian out to pay with his card. After a while, he walked in with a young man who looked somewhat similar to him.
Song Xiaofeng introduced: "Teacher Meng, this is my son Song Jianliang. Now he has opened a small museum, which mainly collects various types of porcelain. I hope you can give him some guidance at your convenience in the future."
"I will ask Teacher Meng for your advice in the future." Song Jianliang smiled and handed his business card to Meng Zitao with both hands. To be honest, when he first saw Meng Zitao, he was a little surprised at how young he was, but when he saw his father's attitude, he was relieved.
"You're welcome, let's learn from each other." Meng Zitao exchanged business cards.
After chatting for a while, Song Jianliang put the brocade box he was holding on the table and opened it, only to see a piece of blue and white porcelain inside.
Song Xiaofeng made a gesture of invitation: "Teacher Meng, please taste it."
Meng Zitao nodded, picked up the porcelain piece and looked at it carefully. In fact, as soon as the thing came into his hands, he felt that something was not right, and he roughly found the problem, but he took the thing all the way. , it¡¯s hard to just dismiss people casually, and from this piece of porcelain, he can also see some of the latest imitation Yuan blue and white craftsmanship.
About twenty minutes later, Meng Zitao raised his head and said, "Teacher Song, don't be surprised if I made a mistake."
"No, no, just say it." Song Xiaofeng waved his hand, and he already had a bad feeling in his heart.
"I think this piece of porcelain is not old enough. Why do you say that? Let's take a look at the photos on the phone first."
While talking, Meng Zitao took out his smartphone and called up a photo of Yuan blue and white flowers: "This photo is a partial photo of a Yuan blue and white flower collected by my master. Take a look and see if there is anything wrong with it."
The photo is very clear. After seeing it, Song Xiaofeng and his son felt that there was nothing wrong with it. It was a genuine Yuan blue and white standard instrument.
Next, Meng Zitao enlarged the photo on his phone, selected an area, and began to explain: "We can clearly see these black spots with strong characteristics of the times. Pay attention to the black spot characteristics in this area. , they are distributed in a point-like manner along the direction of the pen movement."
"This is consistent with the fact that small particles that are not finely ground are carried by the craftsman's brush, leaving traces of distribution along the direction of the brush. If you know something about the craftsmanship of porcelain, you should know that the cause of these black spots is that coarse particles are insoluble in in the glaze, leaving behind the original metal oxide.¡±
Meng Zitao paused and looked at the father and son. Both father and son said there was no problem.
Meng Zitao put down his mobile phone, used a magnifying glass to enlarge part of the porcelain piece, and said: "If you look here again, you can clearly see the difference. Why is this? In fact, the reason is very simple. This is the refining and refining of raw materials by modern industrial technology. Traces of the times brought about by purification technology.¡±
"Because the pigments are very fine, the particles are evenly distributed, and they dissolve in the glaze at high temperatures. These dark colors are iron oxides formed by the iron ions absorbing oxygen and oxidizing during the original process. Therefore, they can not be distributed along the direction of the brush stroke, which is why There will be this cross or even perpendicular distribution of the writing directions.¡±
Meng Zitao continued to explain: "Of course, the reason alone is a bit weak. Let's look at the color contrast and the thickness of the color material. From the color of the cobalt blue background and black spots or patches in the photo, In terms of contrast, it is clear and contrasting, the cobalt blue is bright and stable and quiet, and the black or dark blue spots and patches are clearly layered and contrasting with the background cobalt blue.¡±
"removeIn addition, the thickness of the blue and white pigments is also clearly contrasted. The black rust spots indicate that the firing time is sufficient. During the reduction period, the iron ions have sufficient time to be enriched and reduced to iron oxide. The dark spots indicate the coarse particles of the pigments. Not dissolved in glaze. "
"But looking at the color of the porcelain tiles, the contrast of several colors is not obvious, the layers are not clear, and there is no big difference in the thickness of the pigments. This means that the firing time is not enough to enrich the iron ions, so it is restored directly. It turns into iron oxide, and there are no coarse particles of colorants scattered and distributed.¡±
Meng Zitao put down the porcelain piece in his hand: "But then again, we can only observe these characteristics after showing the details with a magnifying glass, and without comparison with the real thing, it is difficult to see these problems because the details are very different. So, it¡¯s okay for experienced people, but for ordinary porcelain lovers, this kind of high imitation is simply a killer.¡±
At the end, Meng Zitao couldn't help but lamented that the current high-end simulation of Yuan blue and white is "changing with each passing day". Today you are still saying that black spots and rust spots are the identity card of Sumali Qing. Tomorrow you will use a heavy pen to thicken the green material. Imitations that imitate the characteristics of dark spots have already been produced; the day after tomorrow, when you point out the artificiality of thickening with joy, the day after tomorrow, imitators will directly switch to using green materials with the same chemical composition, and fire the imitations. Su Qing's characteristics are clearly visible, and they are guaranteed to be fake.
It can be said that the struggle between antique appraisal and high imitation has been wandering between "the road is higher" and "the magic is higher". If you don't study high imitation technology for a period of time, you will be completely behind the times. Just wait and see. .
"Listening to you is better than ten years of reading!" Song Xiaofeng exclaimed. Although he had problems with his stuff, it was still worthwhile to hear Meng Zitao's wonderful explanation. For him now, knowledge is the most important thing. , money has been placed in a relatively low position.
Song Jianliang also nodded in agreement. After listening to this explanation, he was convinced by Meng Zitao. Thinking that at Meng Zitao's age, he was still thinking about how to pick up girls, and Meng Zitao was already a well-known expert in the country. He was somewhat ashamed.
Meng Zitao said a few polite words, and then said: "Teacher Song, I would like to ask, could you please tell me the origin of this porcelain piece?"
"sure."
Song Xiaofeng said: "I actually got this porcelain piece by chance when I was traveling to Xiangjiang. The price was not expensive at the time. After calculation, it only cost more than 600 yuan."
While talking, Song Xiaofeng took a piece of paper and pen and wrote down the place where he bought the porcelain tiles.
"Thank you." Meng Zitao took the paper. The things were purchased in Xiangjiang, so the source is complicated.
We chatted for a while and heard someone knocking on the door. Then several men came in from outside the door. The leader was Lao Bian who left just now.
Song Xiaofeng asked: "Old Bian, what are you doing?"
The old man said embarrassedly: "My friends also want to ask Meng Zitao to help me take a look at something. I don't know if it's convenient."
Meng Zitao smiled and said: "It's not inconvenient. It can also give me more experience."
"Teacher Meng, you are too humble." Seeing Meng Zitao agreeing, everyone was happy and said a few nice words one after another.
Meng Zitao smiled and said: "Please take out the things you want to identify."
Everyone immediately gathered around. Song Xiaofeng next to him frowned and said, "It's okay if you want to ask Teacher Meng for an appraisal, but there must be order. What's going on when you swarm us?"
???????????????????Everyone nodded awkwardly and looked at each other, and the oldest old man was at the front.
The old man took out a feather fan and said, "Teacher Meng, my fan is made of tortoise shell. Please help me with the next generation."
"OK."
Meng Zitao lowered his head and saw that this fan was foldable and had black and gold feathers on it. It was gorgeous and elegant. Judging from the style, it looked like it was used by Western royal families. But when I looked at the material, I discovered a problem.
"Old sir, this fan is not bad, but it's probably not made of tortoise shell."
"Ah, how could it not be made of tortoiseshell?" The old man found it difficult to accept Meng Zitao's statement.
Meng Zitao said: "Listen to me, the appearance of a real tortoiseshell is a nearly round, triangular or polygonal plate, 10 to 20 centimeters long, 1.5 to 3 millimeters thick, with thinner edges, slightly thicker center, and dark surface. Brown translucent body with dark brown and creamy yellow patterns, smooth and shiny; the inner surface is densely covered with white stripes or spots, and has criss-crossing grooves; the texture is tough, the cross-section is horny, and it is not easy to break."
"And your fan bone is actually made from the carapace scutes of ordinary turtles. This scute is rectangular, fan-shaped or irregular in appearance, with different sizes, 8 to 35 cm long and 9 to 19 cm wide. Larger and thinner, with no bevels or parallel layers on the edges; the surface is creamy yellow, with tan or black spots, slightly radially arranged, generally lighter and more transparent than tortoiseshell. Look carefully, is this what I said?"
The old man combined Meng Zitao's story and carefully observed his feather fan, and he found that it was different from the tortoise shell. It was just because the maker handled it well and it was covered by feathers that he didn't notice it.
"Teacher Meng, thank you for your advice." The old man forced a smile on his face, expressed his gratitude to Meng Zitao, and then turned around and walked out the door with his things.
