A few days later, in the middle of the night, near the exit, under the moonlight, there were some shadowy figures, three of them leading horses, the first group of people to go to Henan, and the rest were people who sent each other.

Li Yuhong led the horse and walked beside the Huang family. Huang whispered to him that he should be cautious in his words and deeds after going out, and not to cause trouble; Listen to Brother Zhang's words, there are cotton clothes in the baggage, pay attention to adding clothes, Li Yuhong should respond one by one.

Since the last incident, the relationship between the two has come naturally, and some neighbors with long ears have also heard about it, but there are no rumors about chewing their tongues, after all, there has just been such a thing as Zhang Caier.

After Aunt Li heard about this, she couldn't wait to shake her mouth a few times. I'm busy helping people talk about matchmaking every day, but this dare is taken away by the eagle? Why are you so clumsy, I didn't see Huang's thoughts.

Tiger Head was ignorant, and felt that his mother and uncle seemed to be closer, but he thought that this was the most normal. The three of them have gone through hardships, lived and died together, and they have long been a united and common whole, and they can no longer be separated.

Zhang Cuihu was leading the horse while holding his lame old lady, and on the other side was his sister Cuifeng. Aunt Wang told him: "Since Mr. Abu has entrusted you with such an important task, you must not let down Mr. Wang, and if you can't complete the task, don't come back." ”

"Yes, A-Niang."

Abu over there hurriedly took over: "It doesn't matter, auntie, I explained to them in advance, don't treat this matter as a burden, just go out and see the world." If you don't invite someone, you can get a drawing. If it really doesn't work, then let's do it slowly by ourselves, and there is no hurdle that we can't pass. ”

He knew that Cuihu was a very filial young man, and before the journey of thousands of miles, Aunt Wang was afraid that she would become a burden, so she asked Cuihu to take her sister Cuifeng away. Cuihu begged bitterly, but Aunt Wang just shouldn't; Cuihu knelt on the ground, let the old lady beat and scolded, saying that if his mother didn't go, he would always kneel on the ground. In the end, Aunt Wang couldn't resist him, so he half-carried and half-carried him, and went on the road together.

Later, his legs and feet were red and swollen, and the wounds had been ulcerated for a long time, so he really had no choice, so he asked his sister to find two long logs, make a simple stretcher, beg his father and fellow villagers, take the handle and carry the old lady down, and he crawled behind with a roll. Everyone was touched by his filial piety, helped each other in the midst of suffering, and finally came to the end of happiness.

In the rest of your life, no matter who has something to help, you can see Cuihu rushing to the forefront. In addition, he is steady and takes the overall situation into account, and he is quite prestigious among the younger generation.

In the group of people behind, Bai Boda helped his son lead the horse with an iron head, without speaking, and his wife Xu next to him told his son carefully. When he was about to reach the cave at the exit, Bai Boda said to his son, "Do you know what you are going to do? ”

"Yes, go find a plumber."

Bai Boda patted his son on the head: "I know a fart, it's to find our lifeline." Mr. said, if the hydraulic blower is made, iron can be turned into water, and we don't have to hammer every day, do you understand? ”

"Yes."

Bai Boda slapped the iron head again: "Understand a fart." Go out to listen to your big brother Cuihu, don't make trouble. You know? ”

"Got it. Take care! Mother, take care! Tietou knelt down, kowtowed to his parents three times, and got up to chase the green tiger in front.

Xu wiped his tears with the placket of his clothes, and he couldn't wipe them dry.

Bai Boda patted his wife's shoulder and took the opportunity to wipe the corners of his eyes.

Alas, there won't be anyone's head to shoot in the future!

When it was time to get out of the cave, Abu said: "I thought that we could make some of our own products first, and let you take them with you, first, to explore the market, and second, to exchange for some coils." But now that the weather is getting colder, time is not permitting, and there are still some key issues that have not been solved, so let's talk about it later.

Bring your map with you, and mark it if there is a new location, or if you find a new product, mineral, etc.

The coil is enough for you to use, don't be too economical, but don't be extravagant. When you go out, you must be kind to others, don't cause trouble, and don't be afraid of things, justice is in the hearts of the people. I wish you all a speedy and smooth return, and we look forward to hearing from you at home. ”

The three of them said goodbye, slowly walked out of the hole, and walked away until they were gone. At this time, the moonlight is shining, full of thoughts.

A few days later, Abu and Li Yuanlu were standing together beside a glass furnace about one person high, next to the crucible and glass that had been melted together. Li Baotian, who was in charge of the firing of the glaze, explained to them on the side: "Sir, you have also seen that the problem now is that the temperature is not up to the requirements when it is heated with charcoal; With coke, the sand grains cannot be completely melted, but the crucible is already deformed. Firing glaze in the same way as porcelain does not work. ”

Li Baotian looks like he is in his forties, with a chubby face, and he looks like a rich man if he doesn't look carefully. When he was in his hometown in Shanxi before, he would burn some porcelain bowls and pots to subsidize his livelihood during the slack season, and he had a good reputation in Shili and Eight Townships. So Abu put him in charge of teaching everyone how to fire porcelain, and at the same time took charge of firing the glass.

"It seems that our urgent task now is to get to work on this problem."

The three of them sat down on a rock, and Abu explained that we had to try to make some soda ash, which can be used as a flux for glass firing to lower the melting point. Seeing that Li Baotian looked a little confused, Abu smiled and said Brother Li has to study hard, you can see what it means when you look at my second brother Liu. Li Baotian smiled awkwardly, and Liu Yuanlu answered: "Old Li, I liked alchemy before, but it was all based on some experience and pill formulas, and I experimented indiscriminately. Since the third brother told me some chemical principles, I feel that I understand a lot of principles at once, and all the tests can be carried out according to precise standards and temperatures. But the specific principles and steps, let's talk about the third brother, hehe. ”

"Then I go on to say, if we take the temperature of the water when it freezes at zero degrees under normal conditions, and the temperature when the water boils at 100 degrees. Then the flame temperature of charcoal is generally 600 to 700 degrees, the temperature of coke burning can reach about 1,300 degrees, if you use a large blower, it can reach about 16 to 1,700 degrees, if the wind is stronger, to the point of the so-called perfect fire, the temperature can reach about 2,000 degrees.

In the process of firing the glaze, the temperature of at least 1,700 degrees is required to simply melt these sand stones, that is, quartz, and we can't do it at present, so we need soda ash to help melt, and after adding soda ash, the quartz will melt at about 1,300 degrees. With what we have, we can do it. ”

Li Baotian rubbed his hands and said excitedly: "That's great, if you can melt all the quartz, it will be easy to do." But as you saw just now, the mold couldn't resist the high temperature, and it was melted into a lump. ”

"Brother Li, did you make the mold you fired before directly with clay, and use it directly after heating and firing?"

"yes, how else would it burn?" Li Baotian is still very confident in this aspect.

"Hehe, the little brother will teach you a way, you make the clay into thin sheets, it doesn't need to be too thin, just the palm is thick, and it is fired first. Find another sledgehammer and break them all into pellets, no larger than the thumb cap, and collect a piece.

You ask Second Brother Liu for some saltpeter, add water, let it be boiling for a long time, and then take this water to stir the broken particles, make embryos, and re-fire, such a mold can at least resist the high temperature of about 1,350. ”

"That's fine?" Li Baotian stood up excitedly and spun around a few times, but he was skeptical of Abu's words.

"That's fine, to be honest, it's a matter of firing it one more time, at most adding some nitrite solution in the middle. In addition, you need to fire more raw material particles, I will give you the drawings next time, we need to make more such refractories. ”

"Okay, as long as you know how to do it, I'll find someone to do it now." Li Baotian happily went.
