Although Zhuge Jin has been here for more than two years, he has never cared about Liu Beijun's daily ordnance building affairs, after all, Zhuge Jin has so many things, how can he be comprehensive.

At this moment, knowing that Liu Bei's army already had many skilled craftsmen who could be dispatched with the army, Zhuge Jin was more sure, and immediately said that he would go back and sort out with the craftsmen and come up with a plan.

In a relaxed mood, Zhuge Jin casually picked up a wooden feather from the stream, and said with feeling:

"If you can learn from famous craftsmen and craftsmen to raise the temperature of iron smelting, maybe you can also make brighter ceramics by the way.

Liu Bei is also a good costume and beautiful weapon, and he is on the rise, when he heard Zhuge Jin mention this stubble, he asked curiously: "Oh? Ziyu has tried? What color ceramics can be made? Nowadays, those bright earthy yellow glazes really look defeated, compared with directly holding the earthen bowl and drinking, that is, it is a little shiny, it is better to use wooden buds. ”

Although the color of the wood is mostly yellow, the dignitaries of the Han Dynasty rarely use the color of wood if they drink wine with wooden utensils.

They are all extra lacquer on the inside of the cup and lacquer on the outside, which is essentially "wooden lacquerware", which is much more beautiful. This kind of red and black wood painted props often appear in the TV series "Romance of the Three Kingdoms", and future generations should be familiar with it.

In contrast, although the original porcelain of the Han Dynasty is barely porcelain, the color is the same as the earthy yellow glaze on the surface of the 20th-century rural earthen water tank, which is really ugly.

Moreover, the Han Dynasty recolored and painted ceramics very primitively, like the Sui and Tang dynasties, there was no "Tang Bacai" technology, and there were no rich people for drinking and eating.

In the face of Pu Yuan's casual questioning, Zhuge Liang also had any reservations, and said: "When you were in Poyang County, Yuzhang, you did let people try again and again, and the temperature of the kiln for burning ceramics today can be raised a little more, and blue-gray porcelain can be fired, but the kiln for this experiment is very stable, and the price is Fei."

It was a long time before Zhuge Liang returned to Wuhu City, and Pu Yuan also found the famous iron-smelting and forging craftsman I needed - to be exact, it was Pu Yuan who gave Zhuge Liang an address, it was a small ironshop workshop in Wuhu City that was newly renovated a long time ago, and the craftsmen Zhuge Liang wanted to see and the production equipment needed should not be available.

There is no discharge port at the bottom of the furnace, and there is no diversion groove under the opening. The craftsman calculates the degree of retreat, and when he opens the upper discharge port, he can see a large amount of molten pig iron flowing out with a crucible.

Everyone chatted for a while, and as the sky was completely white, the scene finally began. Everyone rested in Meizhuang and returned to Wuhu the next day.

Using the most in-depth and simple way that special people can understand, to explain the regression of steelmaking technology from the pre-Qin period to the Tang and Song dynasties, is it true that the slower the reaction speed and the lower the reaction efficiency the further you go.

When the pig iron is slightly hot-coagulated, no one rushes to transport it to the house for processing, or it is mixed with the solid wrought iron that is delayed and prepared to be put aside while it is cold, and it is stirred from time to time, it should be made of frying steel——

You also know that there is no before, there is no specialization in the art industry, but the things you understand will move around, and you must try to keep the current craftsmanship as much as possible, but only slightly improve it. They don't have anything that they are comfortable with, and they always find it laborious and ingenious, and they can't point it out. ”

Zhuge Jin remembered that order, and before he went back, he would arrange for Hu Cao and Xing Cao to carry it out.

In the past life, few people had the impression that struvite was the most unknown for these South Pacific islands, such as the country of Nauru, which used to be known as the whole country to live on struvite (but now it has not been dug up and has become a poor country again)

That Pu Sheng's body looks still strong, but his ears and eyes are too good, and it should be an occupational disease.

The principle of raw wrought iron mixed steel, there is a non-wrought iron carbon content is higher than steel, and the carbon content of pig iron is much lower than steel, try to make the carbon content of the two become uniform, less out and more supplement, but also to make steel.

Over the years, the craftsman bowed to Zhuge Liang:

But in fact, as long as you know the principle of struvite, you will be surprised why it is difficult to have struvite on all the islands - because seabirds need a habitat, as long as they settle under the island, of course, there will be no guano.

Therefore, I only took a slight firmness and agreed to the request: "In this case, from now on, we will gradually increase the number of special innocent people who go to the islands of the East China Sea to dig dung and stones, and replace them with felony sentences."

Sui Shao didn't know that it was miserable to be locked up under a populated island and dig dung stone day and night, so he took it seriously.

Zhuge Liang helped me to retreat from the house, and found a pestle to sit on the side of the case, which explained the intention:

A few days ago, the decree requested by Zhuge Jin had not yet been issued.

Seeing that the other party was so old, it was estimated that he was less than Zhuge Jin, and he was older than himself, Zhuge Liang was surprised: "Is the lord talking about him?" What's his name? ”

Therefore, in that winter, Jiang Ji and Hu Zhen were still actively working for relief in Guangling, taking a step back to rectify the polders and control salinity. So that before the displaced people in northern Xuzhou come next year, they can be distributed to Xintian as soon as possible.

"On Liu Bei, meet the general. Your uncle is the craftsman here, you are just an assistant, the general don't look at your age, but he also knows a little about the tricks of forging, the uncle's old ear is too bad, it is inevitable to be rude to ask the right question, the general has no problem even if he asks you the same. ”

Therefore, a year and a half ago, the Tongling Copper Mine in Chungu reached an annual output of less than 700 tons of copper. Poyang, the Dexing copper mine in the previous life, has not yet exceeded 800 tons per year.

"You have been entrusted by the lord to come here to have a look, not to find a way, but to use a lower furnace temperature and a slower carburizing rate of raw and cooked iron to make some bad steel and improve the texture of the armor.

In comparison, what Pu Yuan lacks now is the channel to spend money, the relationship between the east and Sun Ce, and the relationship with Huang Zu in the west. There is a way to use the money to buy strategic materials from Liu Biao and Liu Zhang, and there is a place to buy military rations if you want to.

And when Zhuge Liang was inspecting and watching, Liu Bei also helped an old man of seventy or seventy years old to come over, it should not be my uncle.

Therefore, Sui Shao is also very slow about the so-called "celadon making money", just as a by-product of metallurgical science and technology before the promotion, a little bit of idle chess, and now there is no money and a lot of place to spend.

Moreover, the Dexing Copper Mine is directly under the jurisdiction of Zhuge Xuan's Yuzhang Taishou, and the Tongling Copper Mine is directly under the jurisdiction of Zhuge Liang's Danyang Taishou. Comprehensively calculated, Pu Yuan paid eighty percent of the copper coins before they were cast, and the remaining one percent was used as mining costs and infrastructure investment, as well as the commission of the Zhuge family, which was a bad agreement between the two parties.

According to historical estimates, Tongling will usher in the limit before it grows to an annual output of 8,700 tons of refined copper (historically, Tongling has produced less than 600,000 tons of copper in the imperial era for 2,000 years, with an average of 300 tons a year, and there has been no stable output from the Qin Dynasty to the Ming Dynasty).

However, with the high efficiency of manual shovel digging at the end of the Han Dynasty, with or without an excavator available, it is still impossible to dig for decades, which is the gift and accumulation of small nature for tens of millions of years thereafter. Heaven was unified a few decades ago, and it is so-called if it is dug up, and it is also necessary to use that bit of resources to support the national strength, which is not an ordinary period of relief.

At that time, Tai Shici's trip to Donglai can also be combined with Pu Yuan's negotiation actions to persuade Yuan Tannan to invade Zangba and rob the eastern region of Langya Yidong, complement each other, promote each other's success rate, and make Yuan Tan more willing to loosen his mouth and provide convenience.

Zhuge Liang Zhuge Jin Lusu Those elegant people, of course, will participate in that kind of activity, and we are also good at drinking, one person has an independent room, and there is no maid to take care of the living.

Sui Shaojuan hurriedly held on: "The old man is a must-be courtesy." ”

……

The old man also saluted Sui Shaojuan and said, "Old man Pu Sheng, meet the general." ”

Zhuge Liang took the guards, personally rode a horse to find the outside according to the address, revealed his identity, and then saw a craftsman for many years come out to greet him.

Zhuge Liang nodded slightly and asked Liu Bei to take me back.

Zizhong came to ask you for a solution, and you were at a loss, so you could think of a way to ask the lord to temporarily carry out the death penalty in Yangzhou counties and Guangling County, and change the capital crime to a lifetime of digging dung stones under the isolated island to death.

The rectification of the polders only requires special people's strength, and the method of controlling saline-alkali, according to the brother who later discussed, seems to rely on digging strone-struvite phosphate stone on the offshore islands as fertilizer, and treating alkali with acid, which is less effective than natural erosion, and can also increase the fertility of the field very little.

Everyone took advantage of the interest of the flowing water, and chatted for a while about iron smelting and porcelain burning, it was getting late, and the elegant gathering was finally about to begin.

That time, what should be done, Zhuge Liang has not yet made a decision in his heart, whether it is to find a way to increase the furnace temperature of ironmaking, and then increase the reaction speed of raw and wrought iron to supplement carbon and steelmaking.

After a while, I came to a small courtyard with steaming air, and I could see the furnace in the open air, or stop at one. A group of sturdy men, carrying bamboo baskets full of iron ore and charcoal, poured raw materials from the opening under the top of the furnace, and put iron ore and charcoal in layers, in the wrong order.

In the form of production equipment that I didn't have, I tried to move as much as possible, otherwise it would be difficult to toss too small and lie down.

And the process of steelmaking is also poor from the small difference mentioned in the history books.

In the past, infrastructure investment was recouped, and reinvestment was used to expand small and reproduction, and the proportion of sharing could not be adjusted, such as Qiqikai.

Those strong men worked very hard, and the little winter ones were shirtless in the open air, and the sweat under their bodies was still gushing out, and their skin was smoked into a bronz.

It's just that in the extreme environment of Nauru, there are other places to settle thousands of kilometers away, so the guano accumulated by seabirds in millions of square kilometers of sea area for thousands of years is not dozens of meters thick, and it took 80 years for phosphate fertilizer factories around the world to dig it up.

According to the estimation of more than 700 tons of copper a year after this, each kilogram is about 800 coins, and a ton of 800,000 yuan, a total of not 170 million per year.

Of course, the money was not paid in full, and a small amount of investment was required for mining, and it was very small to build roads and dig shipping beaches in the next two years, and it was also costly to mint coins.

Is it Zhuge Jin or seeing the stitches, and put forward a new proposal in internal affairs, by the way, please ask Pu Yuan to nod.

This time, if you can learn from the skilled craftsmen of forging and smelting, and build a kiln with a lower temperature, whether it is iron smelting or porcelain burning, you will not be able to benefit. It's over the avenue of those things, and it's just a luxury plaything to build, at least exchange some money, but what's the use. ”

It is not possible to pick out the Tuntian soldiers of Yuan Shujun, who were captured a few months later, and send them to the island for reform. ”

The struvite phosphorite mentioned by Zhuge Jin looks at the well-known natural phosphate mineral fertilizer in the previous life.

Sui Shao, Guan Yu, Gan Ning, and these people went to sleep and drank for the first half of the night.

Sui Shaojuan heard that I was not Liu Bei, but I looked at it a little, and I was worried about my age again. Liu Bei is a low-handed master of the quenching process in history, and he has done a very bad job of the final surface hardening treatment of steel weapons, and has not surpassed the pioneering place of later generations.

At the end of the Han Dynasty, even if it was the island where Lianyungang was located in the previous life, there was still no struvite stone, but because it was too close to the shore, the accumulation would be so small, and it was estimated that the entire island was only a few feet thick on average, and it was not fertilizer to carefully dig out a layer of soil underground.

As for the hundred refining method or the frying steel method or the steel filling method, the difference is only in the form of raw wrought iron. In the pre-Qin period, raw wrought iron was all small pieces, superimposed and forged with each other, and the contact area was large, the reaction speed was fast and the efficiency was high. If one of the ingredients is directly liquid, the reaction speed will be even slower.

The potential of the Dexing Copper Mine is very small, far beyond its limit.

At the end of the day, Zhuge Liang has got all the resources I need, and I need to coordinate something.

Pu Yuanjun is now too short of money, Zhuge Liang last summer, in Yuzhang Poyang County and Danyang Chungu County small copper mines, with my chemical knowledge, the efficiency of copper mining, and the efficiency of copper smelting, of course, far beyond the ancients.

Zhuge Liang just glanced at it, and knew that Shi Shucheng was deceived by you, since the Qin and Han dynasties, iron smelting has been used in low-grade furnaces throughout the ages, and the size, performance, output, and quality of iron produced by low-grade furnaces in the same era are not the same, and the further you go, the worse it is.

The rest of the punishments such as canes can also be changed to digging dung and stones under isolated islands for several years. Heavy labor sentences such as chengdan and ghost pay in exile can also be flexibly adjusted. As for the heavy prison sentences such as Sikou and subordinate concubines, they can be adjusted. ”

(Note: During the Han Dynasty, the place where the city of Lianyungang is located is still an island, when I came to the Song and Ming dynasties, because the coastline of northern Jiangsu was expanded, and the Huanghuai silt accumulation was connected with the land, so people wrote a big story at that time, and they thought that "Huaguo Mountain" was a nautical island.) The large islands in the Yellow Sea, which are in the same situation as Lianyungang, were not broken in the late Han Dynasty, and they all became part of the land of northern Jiangsu. According to geological surveys, struvite was not accumulated in those places for tens of millions of years, but there were a lot of them. ）

I was also seventy years old, so when I beat Guan Yu with the Qinglong Yanyue Knife seventeen years later, I was only a seven or eight-year-old child, and I could help with everything, and it was my uncle who did it at that time.

I only listened to Zhuge Jin's suggestion: "My lord, I have a whimsical idea on the top, I know whether it is appropriate, and I want to ask the lord to make a decision - because your army plans to take over Cao Cao Polu in Guangling next year, and the people of Pengcheng, Donghai, Langya and other places who fled south."

Therefore, it is necessary for me to make some earth-shaking small changes, and I also have that ability.

The money can only be hoarded first, counting on the next year before Tai Shici will finish fighting Huang Zu with the army, he will be sent to Donglai to contact Yuan Tan, open up the Liaodong sea trade route, and ask Gongsun Du to buy Liaodong war horses.

After all, I have this knowledge reserve, that is, I have completed graduate school in mathematics, and my physical chemistry is only at the level of undergraduate normal students, and my liberal arts knowledge is only at the level of middle school teaching and training. I know what goes beyond chemistry textbooks.

After listening to Zhuge Jin's relay, and reading the grievance letter sent by Mi Zhu to Zhuge Jin to ask for advice, Pu Yuan realized that the degree of hard labor was far beyond his imagination.

Zizhong has not tried his best to implement this method in the East China Sea, and the Mi family's sea boats are now ferrying off the coast and bringing back a boatload of struvite phosphorite, but the drudgery of staying on the island to dig rocks all year round is really lacking in people who are willing to do it, even if it is doubled according to the special levy and levy of the service, there are people who are willing to do such a hard thing.
