Zhang Zesheng didn't care about Master Li's suspicions, and said to Master Li: "You first tell me the general process of your process, you can't fire the original colored glass, where is it stuck?" ”

Master Li said: "The most important thing for us is that we can't replicate the color of the original glass." As he spoke, Master Li took a glass cup from the side and said, "This is our recently fired glass cup." Master Li put it on the table, then took out another original glass cup and placed it on the side of it.

Lin Yuan looked at the two glass cups and instantly understood: the newly fired glass cups were far worse than the original cups in terms of color and transparency, so that he, a layman, could see the advantages and disadvantages of the two glass cups at a glance.

Master Li pointed to the two glass cups and said to Zhang Zesheng: "I believe that without me saying, you can also see which glass cup is better, whether you can fire the original glass cup, the most critical place is the proportion of various ingredients, there are dozens of ingredients when firing glass, and the proportion changes are more, so there are thousands of proportions that need to be tried, so we can never try it." ”

Zhang Zesheng nodded and asked, "Is there any broken glass?" ”

Master Li asked, "What do you want to do with the broken glass?" ”

Zhang Zesheng looked at Lin Yuan, Lin Yuan glanced at him, meaning: Don't reveal our secrets, so Zhang Zesheng smiled: "You can find it for me, and I will explain it to you later." ”

Master Li walked to the corner and opened a big box, which contained the glass peacock that Zhang Ziyu broke that day, Master Li held the box in front of Zhang Zesheng, and then said, "Look, the thing is here." ”

Zhang Zesheng looked through the broken glass pieces for a while, picked out a few, and then asked, "These are all the original glass, right?" What about your failed samples? I want a sample of your failures. ”

Master Li sighed helplessly when he heard this, and said, "You come with me." ”

After Master Li finished speaking, he walked out of this cave, and then walked into another cave, lit the oil lamp, and the scene inside surprised Lin Yuan and Zhang Zesheng, because it was really too big, it was three times the size of the cave just now!

Master Li picked up the nearest box and said, "What is contained here are our failures, and every time we fail, we put the glass pieces into this box." ”

As he spoke, Master Li took out another piece of paper from the box and said, "This is the process of firing this glass piece, which records the proportion of each ingredient and the heat. ”

Zhang Zesheng took the piece of paper, looked at it for a long time, and asked, "When you are recording the fire, what does this light cyan, azure and dark cyan mean?" ”

Master Li said, "We use them to represent the size of the fire. ”

Lin Yuan knew that the temperature of the fire was very critical when the glaze was fired, and the temperature may differ by more than ten degrees, and the thing would not be able to burn Shen Yun, and the ancient people did not have the concept of temperature, so they used the color of the fire to record the temperature.

Zhang Zesheng nodded and asked: "Different people must have different understandings of the same color, you look dark cyan, maybe I look at light cyan, I don't know who will record the heat when you are recording?" ”

When Master Li heard Zhang Zesheng's question, his face was solemn, and he said: "It seems that you are really an expert, I have long known about this matter, so we have always asked one person to record the fire, and that person is below." ”

Zhang Zesheng said: "Okay, let your people stop work temporarily, you burn all kinds of fires for me, I want to take a look." ”

Master Li didn't understand what Zhang Zesheng was going to do, but Lin Yuan and Zhang Ziyu had instructed that everything should be done by Zhang Zesheng, so they didn't say much, and went out to prepare, as soon as Master Li left, Lin Yuan asked, "What are you going to do?" ”

Zhang Zesheng said with a smile: "I want to convert these temperatures into the temperatures we are familiar with, I bring an infrared thermometer, and when I record these temperatures, I can start the process restoration." Master Li walked in at this time and said, "The stove is ready, are you going to go now?" ”

Zhang Zesheng nodded, Lin Yuan was just about to go out with him, Zhang Zesheng stretched out his hand to stop him, and then said, "Don't come here, stay here and do something for me." ”

Zhang Zesheng said, took out a camera-like thing from his bag, and then said to Lin Yuan: "This is a visible light spectrum analyzer. Then he took out a flashlight-like thing from his bag and said, "It's a white light source." ”

Zhang Zesheng took the white light source and said: "You use this to irradiate those glass pieces, and then use the spectrum analyzer to shoot the glass pieces, take a reflected light on the front side, and then a transmitted light on the reverse side, and the spectrum analyzer can automatically record the light wave composition of the reflected light and the transmitted light." ”

After Zhang Zesheng finished speaking, he took out the original glass piece from his arms, and then said: "After taking pictures of the fragments in this room, I will record this original one." Lin Yuan asked, "Is it any use to do this?" ”

"With this data, we were able to build a model and then calculate how much we should adjust the ratio and temperature of the various ingredients," says Zhang. ”

Lin Yuan nodded, and the two of them were busy for a day, and then they recorded all kinds of data, and when they returned to their residence, Zhang Zesheng took out a laptop, and then entered all kinds of data, thousands of sets of data, and it took nearly a night to enter them.

Lin Yuan asked, "And then?" You're not going to exhaustively enumerate all possible calculations, are you? ”

Zhang Zesheng said: "How is that possible! With so many circumstances, it can't be counted until the end of the world! Our software is like this, we input the spectral characteristics of the original glass, the software will take this data as the target, and then according to the existing data, automatically calculate and simulate which components and temperatures may be obtained under which characteristics. ”

Lin Yuan suddenly thought of a word and asked, "Is this an artificial neural network?" ”

Zhang Zesheng smiled: "That's right, this is an application of artificial neural networks, this calculation method can automatically learn based on the data we already have, and then generate the results we want." ”

At this moment, the sound of the computer's fan suddenly became louder, and Zhang Zesheng said: "It seems that the amount of calculation is a bit large, and the computer is a little overwhelmed." Zhang Zesheng casually typed in a command, a window popped up, Zhang Zesheng looked at the window, and then smiled: "Let's sleep for a while, the computer will calculate the result for four hours." ”

Lin Yuan and Zhang Zesheng slept in their clothes, and when they woke up, it was already noon, Zhang Zesheng looked at the window and said with a smile: "The calculation results are out, and a total of five groups of the most suitable results have been obtained." ”

Lin Yuan said: "Great, let's send the results to them." "Master Li was already waiting in the firing workshop, and as soon as the results came, Master Li immediately organized people to make the ingredients, and then put the ingredients into the firing furnace, and began to wait anxiously.
