Zhang Dai said the three words "Master Zhao" almost word for word.
After hearing this, Liu San was convinced that the information was correct. The news of Zhang Dai's southward journey had already reached Lingao, but because Zhang Dai's itinerary did not take the sea route, but the land route along the coast of Fujian, the people he handed over along the way were all related to Fushe, so there was no doubt about when Zhang Dai would go. The intelligence department cannot control the situation in Guangzhou or Lingao in real time. Furthermore, although Zhang Dai has a certain status in history and a certain status in Jiangnan Shilin, his intelligence value is relatively not very high, so Lingao just sent a common situation notice to supervisors in various places, saying that such a thing happened , just pay attention when you encounter it. It doesn’t matter if you don’t notice it. With this series of premises, Zhang Dai arrived in Guangzhou during the Chinese New Year. Lingao was busy preparing for war, while Guangzhou was busy celebrating the New Year, so he was ignored.
"Just for sightseeing?"
Zhang Dai is a little annoyed now - maybe I still need to lie to you! However, he has always been known for his elegance, and naturally he would not show his displeasure easily. He nodded slightly and said: "The student is just an idler. He can't stand idle anymore, so he walks around."
"Now is the time of war and chaos, and Guangdong is in the middle of a war again. Sir, this idler has arrived at this time, so we have to be careful about his purpose..." Liu San smiled slightly as he said this, his face full of ulterior motives. smell.
Although Zhang Dai has the arrogance of a scholar, he also knows that "military law is ruthless" during the war. He pondered for a moment and said: "The students came to Guangzhou on a whim, and when the students came, Guangzhou was still under the rule of the Ming Dynasty. The current situation is not what the students expected." Can be expected..."
"I personally believe that Mr. Zhang has no ill intentions in coming to Guangzhou, but it is not easy to travel far away these days. Mr. Zhang will definitely not go to this far south place on a whim."
These words had the flavor of a cross-examination. Zhang Dai knew that this person was here to inquire about his true identity. If the answer did not satisfy him, let alone go sightseeing in Lingao, he might not be able to save his life.
Although he is not a person who is greedy for life and afraid of death, he is unwilling to die so inexplicably. He thought for a while and said: "The purpose of the student's coming here has already been stated before. It is to go sightseeing in Lingao and see this legendary paradise. Apart from the hundreds of craftsmanship, there is no other purpose. The student is just a scholar. He is neither a minister of the imperial court nor a veteran general in the army, and if he asks to see the master of Runshi Hall, he is just looking for someone to take care of him in a foreign land."
"Mr. Zhang is a county magistrate and a literary leader in the south of the Yangtze River. If you are willing to visit us, we welcome you. In fact, when you arrive in Guangzhou, you can contact us directly and we can arrange for you to go to Hainan Island at that time. ." Liu San tried to express sincerity and indifference at the same time, and by the way, he also accused Zhang Dai of not believing in the Senate. Zhang Dai remained silent, and Liu San continued: "But this is just a quick tour, and a deep understanding is also a look. What exactly does Mr. Zhang want to see when he comes to Da Song?"
Just as Wu Mu expected, Zhang Dai simply let go now: there was no fear for his life, and the elder Liu Yuan opposite him was dealing with him cautiously, so why should he be depressed?
"I have always known that the land, water and scenery of this place are unique. The scenery of Australia and Song Dynasty has changed. I heard that the mainland of Australia and Song Dynasty is far away from the waves. I am afraid that I can't go there. I can only go to Hainan to see the customs and customs of Australia and Song Dynasty. ." Speaking of this, Zhang Dai felt that if he only mentioned these things, it seemed that he would be able to see it if he stayed in Guangzhou, so he had to go into more detail. "When I was in Hangzhou, I saw a lot of Australian things. They were all exquisite. What's even rarer is that the shapes are the same in millions. I'm very curious about this. What I'm most interested in is the porcelain from the secret cellar in Australia..." Zhang Dai expressed in detail his interest in the "all-over glazing" technology of Australian and Song Dynasty craft ceramics and his love for secret cellar bone china, and made a request to see it.
This surprised Liu San: Wu Mu’s psychological sketch and behavioral speculation of Zhang Dai suggested that although Zhang Dai was likely to come to Gao to see our social conditions and people’s livelihood, this would not be the main thing. Lingao’s combination of Chinese and Western elements would be mixed with modern Style paintings, music, works, as well as various entertainment methods that have developed maturely in another time and space, and even the indescribable services of Ziming Tower, may be Zhang Dai's purpose of coming to Gao to "take a look". But Zhang Dai now said in front of Liu San that he was interested in large-scale production and ceramic craftsmanship, which surprised Liu San.
The bamboo cup that Zhang Dai was talking about was very familiar to Liu San, because it was a product made by the veterans of the porcelain factory when they took the naturalized craftsmen for the first time to master the high and low temperature processing technology. Several unexpected products from the cellar were kept by the elders for collection. The best ones were given to a few familiar elders, and the rest were packaged as high-end gifts and sold out. As a master of medicine, Liu San naturally has many business contacts with the ceramic industry, so he also received a gift. Liu San definitely didn't know what the specific process was, but he did understand the principle. So Liu San decided to start chatting with Zhang Daiduo from here - anyway, his main job is to chat with Zhang Daiduo, and the recording content will be handed over to the professionals at Wumu for analysis.
"The principle of applying glaze all over the body is not difficult." Liu San replied with a smile.
"Oh? Please don't hesitate to teach me!" Zhang Dai read "Kun Shu" more and knew that Australians do not hide things like principles, but they often avoid talking about specific methods. At that time, a book called "A Preliminary Theory of Optics" only talked about the principles but not the craftsmanship, but it made several members of the society so hungry that they finally had to send someone to Guangli to buy the various mirrors mentioned in the book, but there was no news yet. , I went south, and I don’t know if they got what they wanted. However, from what I have seen on the market during this period, they probably don’t exist in Guangli. If you really want to buy one, I’m afraid you’ll have to go to Lingao.
"The so-called clay is actually the last bits of stone." Liu San felt very tired as soon as he opened his mouth: When he told Zhang Dai about the chemical composition of clay, it must be the sermon of the original Tianzun, one of whom spoke from heaven and the other listened to heaven's book.
"Put it in the cellar to burn it, that is, to burn it and re-condensate it into shape. The same is true for glaze. It is itself some colored stones. Of course, it will undergo some changes in a high-temperature environment, usually a reduction reaction - oh, this is yours Don’t worry, it’s just that the physical properties have changed anyway – so the original color of the glaze and the color after firing are mostly different.”
Zhang Dai was very helpless after hearing this: He also knew that the physical properties must have changed, so the key was the reaction. However, Liu Yuanlao was unwilling to say more. This kind of reluctance is not the kind of reluctance that is afraid of leaking secrets, but an impatient reluctance, just like someone at a cultural meeting raised some questions that should be mastered in elementary school, and others are too lazy to answer them. . Zhang Dai was rarely classified as an ignorant person, so he felt unhappy. He nodded slightly in agreement and continued to listen to Liu San's words.
"But different glazes have different melting temperatures." When Liu San said this, he remembered that Zhang Dai might not have the concept of temperature, so he explained: "If the freezing temperature of water is set as 0 degrees, the water will boil The temperature is set at 100 degrees, so some glazes may take seven to eight hundred degrees to melt, and some may take thousands of degrees to melt."
"When the water boils, won't the temperature rise again?" Zhang Dai suddenly asked.
Liu San was stunned by the question - it was common sense to him that the water temperature reached the boiling point and began to vaporize, and the temperature would no longer rise, but how to prove it? It seems that I have never seen any book that explains it in a simple and in-depth way. In ancient times, there were no thermometers, and temperatures could only be divided into high and low temperatures. It’s hard to quantify exactly, let alone explain. But he couldn't just explain it face to face. Liu San responded tactfully and immediately: "It's true that it doesn't rise anymore, but it takes time to explain the principle. Let's talk about the glaze. Different substances have different melting points, which is not the case in daily life." If you don’t see it, Mr. Zhang can ask a coppersmith and silversmith at random and he will know: if tin, copper, and iron are burned in the same crucible, tin must melt first, then copper, and finally iron.”
Tin melts before copper, Zhang Dai knew that, nodded and stopped interrupting.
"The same goes for glazes. I also know the cup you are talking about. It has two colors inside and outside! There must be one high-temperature glaze and one low-temperature glaze. The high-temperature one is burned first, and then the low-temperature one. Naturally, there is no need to leave a glaze. Yes." Liu San revealed the answer to the mystery in one breath.
After hearing this, Zhang Dai thought carefully: First, burn one color, and the area without paint will be the support point. Then, burn the "low-temperature glaze", and the burned glaze will be the support point. Sure enough, there is no need for mangoes or support nails! It just has to be burned twice and the cost is much higher. His discontinued project was only burned once, and the yield was so low. If it had been burned twice, it would have been stopped by the family long ago. Moreover, Liu Yuanlao's theory is clear enough, but it is still as useless as "Optics Preliminary": after the first cellar is burned, how to control the temperature? What are the "melting points" of different glazes? If I ask carefully, let alone whether this Australian Xinglin master understands it, even if he does, he won't bother to explain it to himself, but I'm afraid he won't understand it very well.
"The utensils are exquisite, the ones from Australia and Song Dynasty are indeed very good!" Zhang Dai complimented.
Finally waited for this sentence! Liu San was overjoyed and immediately asked deliberately: "Sir, do you think this is just a grotesque trick that is of no use to the people?" Finally, he could bring in the rhythm he had prepared!
Zhang Dai was stunned by this slightly incriminating question, but if he thought about it carefully, apart from making some luxuries, such techniques seemed to be of no benefit to people's livelihood! Is there anything else to say? Zhang Dai is actually interested!
"I have no intention of doing so, but... I would like to hear the details!"
