Guo Nuer brought eight soldiers to help, and five kilnmakers built a stove with burning stones and earth overnight. The next morning, he invited Han Qian and the others to see these craftsmen burning lime with their ancestral craftsmanship.

Chen Yang used the existing villages in Taowuji to add more than a dozen porridge farms overnight to evacuate 30,000 to 40,000 hungry people to these porridge farms for relief, and then sorted out the military registration. The scene was not as chaotic as yesterday.

In the early morning, Han Qian and the others went out and saw that the family soldiers and children who were temporarily transferred to Chen Yang by Fan Dahei and Lin Haizheng were taking some of the hungry people to clear the road. It can be seen that Chen Yang's efficiency in doing things is higher than they imagined.

Feng Yi and Kong Xirong stayed in the villa, not as scared as before, so they were not busy going back to the city, followed Han Qian to see the burning lime as a pastime. They also specially sent people to Linjiang Marquis' Mansion to say that they were in the military mansion in the past two days, thinking that they could escape the hard training of riding and shooting for two days.

The third prince Yang Yuanpu has always been very diligent and wants to gain recognition from others. He rides and shoots for an hour every morning and evening, and is called Feng Yi and Kong Xirong, who is accompanied by miserable pain.

After watching the chaos on the lake beach overnight, Han Qian changed. He thought that after they returned to the villa last night, Chen Yang might not have been asleep for a long time, and he didn't know how this little old man could hold on.

On the craftsman's side, the burning earth stove has been built, which is only as tall as the thigh, which is even simpler than the stovetop you usually see. Even the stove door and air outlet are not left. It can be said that it is just a circle of low walls to make the stove. However, a layer of rice and wheat poles and dead branches are directly laid in the stove, and then a layer of blue and white stones the size of a fist is knocked into fist. After igniting it, the top of the stove is sealed with yellow mud to keep the small mouth breathable, which is said to be burned for a day and night.

The whole process is to calcinate, which makes the blue and white stone thermally decompose to form quicklime.

The dreamer Zhai Xinping was very poor in chemistry. He returned all the chemistry knowledge he learned in middle school to the teacher, but he could still know the basic concept. This is also called Han Qian, and he felt that the so-called ancestral craftsmanship of these kiln-fired artists was really rough and very primitive.

The burning of stone and earth stove did not even leave the stove door, so naturally there was no such thing as a furnace.

Without a furnace or air outlet, there is no way to control the fire. If the burning soil stove is built larger and fill it with more limestone at once, how much lime can be produced and what quality of lime will be produced will be completely out of control.

To build a large stove, the key is that the stove must have a furnace or air outlet that can be controlled and observe the fire.

The question is how to build such a furnace and what refractory materials are used. It is not afraid of fire, but it also needs to leave enough holes for ventilation. It also needs to support thousands of kilograms of limestone and firewood charcoal to prevent the furnace from collapse during the burning process?

Han Qian thought that the earth stove burning the stones did not even leave the air outlet, and he used wheat straw as firewood, so the flame temperature of the stones should not be too high, so he asked Guo Nuer to insert a long iron drill used for quarry into the stove from the top of the stove.

After a long time, I inserted the long iron rod out. It seemed that the iron rod was just burned red. It seemed that the fire temperature of the forged limestone was far from enough to melt the iron rod out.

Since cast iron can be used to build a furnace, Han Qian does not think it is difficult to renovate a large stove.

"Build a large stove, leave a furnace for ventilation and fire protection at the bottom. Iron bamboo strips are placed on the top of the stove, and a layer of charcoal is laid on the upper layer to ensure that the stone powder does not leak. Then layer by layer and layer by layer, green and white stones and firewood, burn for a few more days to see the effect!" Han Qian called Fan Xicheng over, drew the planned case handling paper and pen, explained it to him, and asked him to find a few tenants to come over and help Guo Nuer and several kilnmakers try to build a large stove.

"Sir, if this fails, thousands of kilograms of green white stone and dozens of loads of firewood will be destroyed in an instant." A kiln maker felt that Han Qian was a little erratic, and he mustered up for a long time to come and advise him with kindness.

Only when an ordinary craftsman works hard in a year can he get five or six thousand yuan.

Two or three thousand kilograms of Qingbaishi were destroyed. For these kilnmakers, it was equivalent to working for three or five months. They really didn't dare to try the new method easily, but if Han Qian couldn't even bear to waste this little bit, what else would he want to do?

Han Qian smiled slightly. He didn't want to explain too much at this time. After all, these kiln makers don't know a single word, their ideas are outdated and stubborn. No matter how much he tried to explain, it would be better to direct them to see the results directly.

"How can you do this?" Feng Yi pulled Kong Xirong to watch the fun. Seeing that Han Qian had never had such a cheap career before, he heard these craftsmen say it last night that he had seen the earth stove built by others early today, and he had to directly renovate the large stove. He didn't think it was reliable.

"If I could make some tricks, how much money would you lose to me?" Han Qian asked Feng Yi with a smile.

Although in the middle and late period of the previous dynasty, the separatist ruled the vassal states and the influence of the imperial examinations just started was relatively limited, so scholars were not so noble, and the noble families were relatively pragmatic, but no one would engage in these low-key careers, let alone have a dedicated person to study them.

This makes it possible to improve every traditional craft in the world that needs to be accumulated by generations or even dozens of generations of craftsmen, and the whole process is naturally extremely slow.

Although Han Qian had no fantasy that he could become the shocking industrial system in his dream out of thin air, he could not make a certain degree of improvement in such a simple craftsmanship that was in his time. He really felt ashamed of the thinking and knowledge that dreams brought him beyond this era.

Of course, Han Qian didn't expect to build a large kiln that could produce tens of thousands of kilograms of quicklime at once. He decided to first transform it based on the civil method and try it step by step. Then he asked Fan Xicheng and others to organize their own hands to specialize in quarrying operations and conduct division of labor and cooperation. He believed that the output of the stone-burning kiln he built was beyond the reach of others.

"A gold-making money." Although Feng Yi didn't believe that Han Qian could do everything, he learned his lesson and would not jump into his pit casually.

Han Qian rolled his eyes to Feng Yi, and he was too lazy to pay attention to him only with a bet of gold.

Before, although Fan Xicheng was responsible for building houses and courtyard walls in the villa, he hired nearby bricklayers to do things. He just took other soldiers as supervisors to stare at them.

At this time, he was asked to come on stage in person and work with the tenant who didn't understand anything. Han Qian just drew a brief picture with paper and pen, and said it in a slight way. He seemed to understand, but he was a little confused when he actually started to do it.

The earth stoves built by those stonemasons used their experience, and the stove walls were not as high as the thighs. The more important thing was that firewood, charcoal and gravel were piled directly on the ground. The earth stove did not bear much weight, so it didn't matter if it was built crookedly.

The large stove that is to be renovated now has a double diameter circumference, and a stove chamber is left below. It is also planned to stack six to seven layers of limestone and firewood, which should be almost one person tall. The stove chamber must be suspended in the air with a heavy pressure of five or six thousand kilograms of gravel and firewood, which is much more difficult than imagined.

The stove wall is a little tilted, and the big stove may collapse before the lime is burned out.

However, Fan Xicheng didn't want to show his fear in front of the young master Han Qian. He led people to pick up bricks and mud in the house, so he started to do it first.

It was said that it was a big stove, but it was only two steps away. Han Qian, Feng Yi and Kong Xirong returned to the villa for breakfast. After watching the sun climb up to the treetops, he then took Qingyun, Zhao Ting, Zhao Tinger, Zhao Wuji and others back to the craftsman's workshop. He saw that the stove wall had been built to a height of half a person, and the speed was not slow.

But no matter how you look at the stove wall, it is all crooked.

"Do I send someone to the Shaofu to find a master craftsman to help you? Otherwise, the stove wall will be overturned and you will lose one gold piece of money." Feng Yi asked gloatingly.

The truly skilled craftsmanship near Jinling has almost been recruited into Shaofu.

Whether it is the construction of imperial palaces, the firing of utensils used by the royal family, the weaving of silk robes, or the casting of ships and weapons by the guards, or the casting of coins, they are all the most exquisite creations in the world, or at least the Jianghuai region.

The excellent craftsmanship that specializes in his work is mainly concentrated in Shaofu.

Fan Xicheng, who was standing aside, had a red face, but he felt that Han Qian was trying to assign him to do this, so it was a bit difficult for him to send someone to invite an old master to come now.

Fan Xicheng is also a capable person, but it is obvious that there is still a big gap with the kind of ability that Han Qian expects. He sighed and said to Zhao Tinger: "Tinger, tell Mr. Fan how do you think about whether the stove wall is straight or not straight!"

"Your servant is worth a master?" Feng Yi asked with a smile.

"If Zhao Tinger can command these craftsmen and build a big stove, how much will you lose to me?" Han Qian just happened to teach Zhao Tinger how to measure the level and how to compare vertically in the past few days. He smiled at Feng Yi and asked.

"Zhao Ting'er can use these craftsmen to build a big stove. I'll give her this Hepu Pearl!" Feng Yi took out a Hepu Pearl with a big long eye from his arms and glanced at Zhao Ting'er.

A longan-shaped Hepu pearl is worth about 100,000 yuan, which is definitely a rare thing in Jinling. Seeing that Feng Yi actually made a bet and did not forget to seduce Zhao Ting'er, Han Qian spat in his heart and said to Fan Xicheng: "You find more than ten people to go into the mountain to pick green white stones, which may come in handy at night."

Fan Xicheng knew that the young master Han Qian had always had a lot of opinions about him. At this time, he saw the young master Han Qian sending people to the mountain to quarry and handing over the construction of the stove to the half-grown little girl, and he felt so resentful.

However, before Han Qian came over again, Shen Yang also sent someone to ask when the lime kiln would be completed. Fan Xicheng dared not delay this matter. No matter how resentful he was in his heart, he could only choose what he could do.

Zhao Tinger and Zhao Wuji's father, Laogong, were just in time for the slack season, and were also pulled by Fan Xicheng to help build a stove. At this time, he went to the corner and quietly pulled his daughter's sleeves, advising her not to show off.

Old Man Zhao thought to himself that if this girl caused the young master to lose such a big bead, she would not be able to pay for it even if she sold it.

Besides, how can a girl interfere in such a big thing as building a big stove? Isn’t this a bad thing?

Zhao Ting'er was eager to try and ignored her father's dissuasion.

The stone-burning masons were unwilling to do so, but they didn't dare to say anything in front of Han Qian. They just looked at Zhao Tinger, regardless of the mudiness in the field after the snow melted, found a small piece of wooden board, tied a copper coin to the small board with silk thread, and made the simplest thread hammer.

Press the thread to the stove wall that is half a person tall, so that the copper coins will hang straight down. Once you compare it, the crooked stove wall will become more obvious.

"Do you see clearly? Make a few more pieces of such a thread hammer, and make two or three layers of bricks straight, and the whole body will not be crooked upwards." Han Qian always forgets to beat Fan Xicheng and other family soldiers when he has the opportunity.

Fan Xicheng was ashamed and didn't know how to speak.

The stove wall does not involve woodwork, and it is the key to building it straight. Seeing that Zhao Tinger used such a simple method, he grabbed the key points directly. Feng Yi was also a little stunned and couldn't help but clap his hands and praised: "This method is wonderful. It turns out that the wall is straight or not, it's so simple," he asked Han Qian with great urgency, "Why do I get ten Hepu Zhushes and give me such a smart servant?"

"That's you guys," Han Qian ignored Feng Yi. Seeing those craftsmen, the tenant even thought Zhao Ting'er was a girl and scolded him, "Train the stove wall and rebuilt it! Also, carry a few bags of lime and trip into the mud to build the wall!"

The villa has prepared a batch of lime emergency first. Han Qian thought that it would be more firm to build the stove wall with lime.
Chapter completed!
