The next day, at the foot of Qingliang Mountain in the west of the city.
That's right, it's not far from Shunfengxing Racecourse.
His Royal Highness Prince Chun's porcelain kiln is located here.
The place is not big, there are only two kilns in total.
The prepared soil embryos are drying on rows of racks in the yard, waiting to be fired in the kiln.
The craftsmen and workers were coming and going at work, making it a lively scene.
"Brother Lu, your business here is quite prosperous."
His Highness Prince Chun smiled slightly, but did not say that the products from this porcelain kiln were exclusively for the royal family. He just casually took out a teacup from the finished product shelf next to him: "Sir, please see, this quality should be good for making wine bottles."
Bar."
Yang Xuan picked it up and looked at it carefully. It was indeed quite exquisite. As long as he designed a unique shape, it could be used as a wine pot. However, he also wanted to study whether it could be made of glass.
Even if you can't make glass of the same quality as later generations, it's good to be able to make something similar. As long as you find the right direction, the rest can be left to the craftsmen.
Yang Xuan didn't know how to make glass, but he still knew the general direction: "What raw materials are used to make this thing?"
His Highness King Chun didn't understand either, so he called a craftsman casually: "Can you explain to him what raw materials are used to make porcelain?"
Although the craftsman didn't know the two of them, he saw that they were dressed luxuriously, so he briefly explained the production process, which was nothing more than clay training, embryo making, carving, glazing, and firing.
"Master, can I burn colored glaze?"
The craftsman looked at Yang Xuan with a strange look, bowed his hands and said: "I still have things to do, please help yourself."
After the craftsman walked away, His Highness Prince Chun looked at Yang Xuan with a strange expression.
"What? You don't believe that colored glaze is made by firing?"
"The colored glaze is created by heaven and earth. It is said that the colored glaze is collected from around the volcano. How could it be fired?"
Yang Xuan showed a mysterious smile: "You also said that it was picked near the volcano. How do you know that this glass was not fired in the volcano?"
"Even if it is fired, it is fired by earth fire. How can we mortals do it?"
"I think this earth fire is just a flame with a higher temperature. It is essentially the same as the fire we usually use for cooking."
"Why is the temperature higher?"
"It means a more intense fire." Yang Xuan said: "This porcelain kiln cannot produce colored glaze. Is it possible that the firing temperature is not enough?"
"Do you know how to make colored glaze?"
Yang Xuan shook his head: "I just think it's possible. If the fire is more intense, maybe glaze can be made?"
His Highness Prince Chun didn't understand this. Although he thought Yang Xuan was a little whimsical, Yang Xuan had always been truthful in his words, so he still found the person in charge of the porcelain kiln.
The person in charge of this porcelain kiln is also a slave from his hometown, just like the shopkeeper of the carriage and horse shop. When he saw His Highness Prince Chun, he immediately saluted and addressed himself as his boss.
"This is Shopkeeper Qian of this porcelain kiln. He has more than 40 years of experience in making porcelain. Sir, you can discuss the matter of colored glaze with Shopkeeper Qian."
Yang Xuan organized his words a little and asked: "Shopkeeper Qian, when firing in this porcelain kiln, do you need to control the heat?"
Shopkeeper Qian first cupped his hands and then said: "Yes, it doesn't matter if the time is too long or too short, it needs to be just right."
"Then Shopkeeper Qian, is there any way to shorten the firing time, such as making the flames more intense?"
"Shortening the time won't work, but there are ways to burn the flames more intensely."
When he heard that there was a way, Yang Xuan was slightly excited: "What method is it?"
"Sometimes the leftover coal becomes coke. This coke cannot be used to make porcelain. The fire is too strong and the temperature is difficult to control."
"Yes, yes, it's coke with a stronger fire." Yang Xuan excitedly grabbed Shopkeeper Qian's arm and said, "I want to bake something special, and I need to use coke. Shopkeeper Qian, do you have any here?"
Coke?"
"There are quite a few. I just use them for making fires and cooking."
"Let's take a look." In fact, Yang Xuan didn't understand anything about coke, but he heard that there were a lot of them, so he wanted to take a look immediately.
It's said to be quite a lot, but in reality it's not much. It's about as much as a small mound of dirt about the height of a person.
But since there is coke, the matter is basically half done. Yang Xuan pulled His Royal Highness Prince Chun aside: "Brother Lu, is this money shopkeeper reliable?"
"Sir, don't worry, this person is absolutely reliable."
Although His Highness King Chun said so, Yang Xuan couldn't help but ask: "If he can bake colored glaze, can he keep the secret strictly?"
His Royal Highness Prince Chun once again assured: "Sir, you can rest assured that I won't let him say anything. Even if I move my head, he won't say a word about it."
Just as he finished speaking, he suddenly realized something: "Do you really know how to make colored glaze?"
"I'm just guessing, but there is a certain possibility." Yang Xuan said this is still a bit conservative. Since there is a direction, it will be researched sooner or later.
"Then you might as well give it a try."
The price of colored glaze is comparable to that of jade. Although His Highness Prince Chun has no shortage of good jade, this thing is really not cheap. If it could be fired, it would be a cornucopia.
Yang Xuan called Shopkeeper Qian over again and said seriously: "I have a method that can make colored glaze. Would Shopkeeper Qian want to try it?"
Shopkeeper Qian looked at Yang Xuan with the same look as the previous craftsman, but for the sake of His Highness Prince Chun, he still said honestly: "My dear, glass is a natural thing, how can it be fired?
?”
His Royal Highness Prince Chun on the side said: "Since Sir asked you to try it, you should try it."
"Since my boss said so, let's try it."
Yang Xuan glanced at His Royal Highness Prince Chun with dissatisfaction: "This is not an attempt, but an in-depth study. Just like when you are making porcelain, you need to devote your efforts to success."
Seeing that Yang Xuan spoke so solemnly, Shopkeeper Qian looked at His Highness Prince Chun again.
His Royal Highness King Chun nodded and said, "Sir, what you said is exactly what I said."
"Yes, the villain will go all out."
After getting the attitude he wanted, Yang Xuan talked about the ingredients.
It’s nothing more than quartz stone, limestone, and soda ash. These raw materials are all available in Dasheng.
Of course, these things alone may not be enough, but Yang Xuan didn't know about other things. He only knew that chemical raw materials such as potassium, calcium, and sodium should be added to it, so he named a few more raw materials that he could try.
Such as mineral salt, plant ash and the like.
There is also a need to build a new firing kiln. It is not as big as a porcelain kiln for the time being. However, Yang Xuan also warned that the fire should be made as fierce as possible. The fiercer the better. As for how to make the fire more fierce, there is still
It depends on shopkeeper Qian to research it.
On the way back, His Royal Highness Prince Chun asked in disbelief: "Can you make colored glaze with just the things you mentioned? You must know that those things are very cheap."
"Natural things are so magical. Let's wait and see. I don't know when it will be done. I only know that this direction must be right."
Returning to the hot pot restaurant, I ran into shopkeeper Zhou. At this time, he was looking anxious. As soon as he saw the two of them, he hurriedly grabbed Yang Xuan's arm: "Something happened, something happened."
