Meng Zitao smiled and said, "This classmate said it well. Have you ever researched bronze tablets before?"
Wu Feng shook his head and said, "No, I just saw it in a book by chance."
"It seems that this classmate has an outstanding memory."
Meng Zitao laughed, and then said to everyone: "Are there any students who know more about bronze tablets?"
Seeing that no one responded, Meng Zitao didn't care, so he explained to everyone: "In fact, the bronze tablet I brought today is actually an antique work from the Ming Dynasty. Antique artifacts based on pre-Qin bronzes first appeared in the Song Dynasty, and were accompanied by With the continuous deepening of collection and appreciation, the famous copper-making masters at that time combined the styles of Shang and Zhou bronzes with the new copper-making technology of this period, and produced a batch of bronze works that are both antique and characteristic of the times."
¡°In the Ming Dynasty, with the literati¡¯s admiration for antiquity, the market for antiquities flourished, forming a trend of pursuing, admiring, and loving antiquity. The appreciation of ancient artifacts gave rise to an appreciation of the ancient and the new, which also drove the direction of artistic creation. This This piece combines the ancient with the new, not only inheriting the style of antiquity, but also using green particles to further enhance the ancient decorative effect of the pattern on the basis of the gold and silver craftsmanship of the Spring and Autumn Period. This also proves that it is an antique bronze ware of the Ming Dynasty. evidence of."
"Now, please take a look at the bronze tablets displayed on the curtain. These are works from the Zhou Dynasty and the Spring and Autumn Period and the Warring States Period. You can compare it with the table to see what is different"
Next, Meng Zitao introduced the pre-Qin bronzes in a simple and easy-to-understand way, and used the bronze tablets he brought to explain the characteristics of antique bronzes in each period.
Meng Zitao set the time and finished the main lesson with about ten minutes left.
¡°Okay, that¡¯s it for today¡¯s class. If you have any questions, you can ask them.¡±
Han Yimao immediately asked: "I often hear that the rust color is required to identify bronzes. How do you look at this rust color?"
Han Yimao's expression was a little careless when he spoke. Meng Zitao was quite unhappy and said: "Common patina colors include green rust, red rust, blue rust, black rust, purple rust, etc. The specific situation, we will definitely talk about it in this class. It¡¯s not over, I don¡¯t want to be blamed for wasting everyone¡¯s time, we can talk about it after I bring the real thing to the next class.¡±
Han Yimao was a little angry. Meng Zitao's simple words were clearly to deal with him.
"Who else has questions?"
¡°Teacher, what¡¯s going on with the bronze gasket?¡±
It was Wu Feng who asked the question. Of course, Meng Zitao would not hesitate to answer those who were polite.
"In fact, the formation of gaskets is related to technology. The casting process of ancient bronzes mostly used the mold casting method, that is, using clay to make molds on pottery molds. Generally, solid bronzes such as swords, clusters, etc. can only be made using external molds. There is no need for spacers; and those hollow bronzes such as pots, fou, gui and some thin-walled containers, etc., need to be assembled with inner and outer molds before they can be cast."
"The gap between the inner and outer molds is the wall thickness of the object. The error in the gap between the inner and outer molds should be controlled using some methods or technical measures. Otherwise, it will directly affect the uniformity of the wall thickness of the object, and even become a Waste product. In order to ensure the quality of the utensil, it is necessary to ensure that the gap between the inner and outer molds is even, and the inner and outer molds are fixed before pouring so that they cannot move freely."
"Using red copper sheets with different alloy compositions and the same wall thickness as the objects being cast, they are called gaskets. Craftsmen regularly place the gaskets on the surface of the outer mold. Most of the gaskets are square and shuttle. Shape, or sheet red copper. During the casting process, when the bronze solution of about a thousand degrees is poured into the mold cavity, these gaskets will be melted away, some will be displaced by impact, and some will be enveloped by the copper liquid. live, and some are exposed on the surface of the utensils.¡±
¡°Generally speaking, the traces of gaskets on the surface of bronze vessels unearthed from water pits are clearer and more obvious, and it is not difficult to find them if you look carefully. The traces of gaskets on the surface of bronze vessels unearthed from dry pits are more vague. Although they are rusted to the same color, you can easily identify them if you look carefully. Even if there are marks around the gasket, you can still find them"
Meng Zitao's detailed explanation made Han Yimao very angry. His questions were perfunctory, but Wu Feng's questions were so detailed. This was clearly a public revenge!
Meng Zitao didn't bother to pay attention to him and continued to let everyone ask questions. There were all kinds of questions, and the one that everyone was most interested in was undoubtedly the missing antique. However, Meng Zitao did not talk too much about this aspect, so as not to mislead the students. If it was because of himself that any of these students failed to pick up the slack, it would be his own fault.
"Do you have any questions?"
"Teacher, do you have a girlfriend?" The person who asked the question was Yue Hui.Does Master still collect antiques? "
Teacher Lu shook his head: "Hey, since something happened in high school, I won't touch this thing."
It turned out that one Sunday in his second year of high school, he went shopping with his grandfather and happened to see three men carrying a black handbag coming to the intersection and openly selling "antiques", claiming that they had just been dug out of the ground. , passers-by gradually gathered over, and some began to bargain.
Out of curiosity, Teacher Lu also went over to take a look and found that the handbags of the three men selling "antiques" contained a "jade". The jade was carved with an auspicious animal and had some yellow mud on it.
"They treat this thing like a treasure. They put it away immediately after looking at it, and squeeze the handbag tightly." Teacher Lu said: "One person first offered two thousand yuan, and then gathered together Several people said they didn't have that much money with them, and after some 'bargaining,' the two parties finally determined that the transaction price was 800 yuan."
"Then several people started to collect money. At that time, I didn't know whether they were really collecting money or fake it. However, because I had seen similar scams, I casually questioned on the spot, 'It can't be fake, right?' Who knows about selling 'antiques' The man immediately and viciously replied to me, "It's none of your business, mind your own business." I was young and energetic at the time, so I started scolding me on the spot, and then I even used my hands to hurt my grandfather's head. "
Meng Zitao said: "Why are you so arrogant?"
"That's right!" Teacher Lu gritted his teeth and said, "Those people didn't do anything serious. After my grandfather was cured later, he still had headaches every time it rained on cloudy days. He died within two years. It should be related to this incident. It¡¯s not irrelevant. Because of this incident, I feel very guilty. Every time I see antiques, I can think of this incident, so I just ignore it.¡±
Meng Zitao nodded, he could also understand Teacher Lu's approach.
After a moment of silence, Teacher Lu smiled slightly: "Teacher Meng, I'm really sorry for talking about such unhappy things."
Meng Zitao waved his hand and said it didn't matter.
Teacher Lu toasted Meng Zitao with tea instead of wine to express his apology: "Speaking of it, it has been more than ten years. I have never taken out the things I bought before. I don't even know what they are now. Are they true or false? When I get back during the winter vacation, I will bring them over and ask you to help me identify them. Is that okay?"
"No problem at all¡¡"
Because he was going to Xiangjiang, after dinner, Meng Zitao thought of something, so he went to the antique shop again and explained the matter to Hu Yuanliang.
As soon as he finished speaking, Meng Zitao saw Lao Niu running in shouting: "Sir, I have something to ask you."
"What the hell?" Meng Zitao asked with a smile.
"That's it. It's said to be made of rhinoceros." Lao Niu took out a carved object.
Meng Zitao laughed: "Old Niu, do you know what Bixi is?"
Lao Niu nodded and said: "I know, it is recorded in ancient books that the bones of rhinoceros are as strong as rhinoceros when it came out of Western Tibet. Its color is like light jasper, slightly yellow, its texture is like horns and bamboo, and the sound of buckling is clear as jade. It can be scratched and smelled. Incense, which does not stink when burned, can reduce swelling and poisons, and can identify poisons. It is also called green rhinoceros, which is the most expensive!"
The bone rhinoceros is also known as snake horn. Snake horns do exist in the history of our country and are recorded in historical records from the Jin Dynasty to the Qing Dynasty. "Compendium of Materia Medica" also records that it can relieve various poisonous poisons. However, because most of these historical data are rough and not detailed enough to describe the true appearance of snake horns, and snake horns disappeared before the Qing Dynasty, there has never been a scientific definition of the basic concept of snake horns.
In other words, what exactly are snake horns? From ancient times to the present, no one can really say it clearly. In modern times, the name of snake horns has become even less well known. In addition, there have been no records of physical utensils being released. Currently, there is almost no relevant research in China.
Meng Zitao smiled and said: "Whether it is Bixi, you can tell if you scrape it off a little and smell it?" (Remember the website address: www.hlnovel.com
