Which person said that it is easy to make glass after crossing, the pit is dead, there is only coke and raw materials, there is no process, and the glass cannot be made.

Ceramic kiln and glass kiln seem to be similar, in fact, there is a big difference, the full inverted flame kiln is the highest temperature in all ceramic kilns, the chimney goes deep into the bottom of the kiln, all the hot gas that rises up is evenly led to the bottom of the kiln, forming a comprehensive inverted flame, but glass firing is much more difficult than ceramic firing, the temperature is enough to consider the process, in short, industrialization is really not a person can play, now the two knives of Zhixiu are a little blind.

But no matter what, he is also better than the Saga gang who have no clue at all, and in order to make friends with Saga Qunying, he can't do it without showing some real materials, and don't think about changing the world just by relying on "Wanhachi" (bragging), so he can only fight Taiping boxing and paddling.

Naohide and Saga represent Hamuro Heinoyoshi, Shiba Sadenta, and Motoshima Totoo in three chapters: first, Naohide does not guarantee that it will be able to make glass; Second, in the process of glass production, Zhixiu must have decision-making power, that is, a one-vote veto system, and do not interfere with people who mess around; Thirdly, Naohide will make a plan, how long it will take and what should be done in each stage, and then Saga will estimate the cost, and then report it to the feudal office, and Naohide needs an official document from the feudal office to agree to the terms and exempt Naohide from relevant responsibilities - if it fails, you can't find Naohide's small account.

Saga everyone looked at each other, in fact, they had the attitude of having dates and not hitting a shot, if they became the best, they didn't want to spend too much money and energy.

Naohide didn't care what they thought, he directly picked up people, asked them to go back and think about coming back tomorrow, and then summoned the two students and the guest general Murata Yongmin to make a plan.

One of the reasons Naohide makes glass in Saga is that there are plenty of raw materials. Nagasaki's Unzen ware, Mikawauchi ceramics, and Hasaami ceramics are famous, and Saga's ceramics are also domestically produced, and the glaze for ceramics includes feldspar, quartz, talc, kaolin, and more.

The glass formula used for Naoxiu preparation is high-quality quartz sand, limestone, feldspar, and potassium carbonate. The first three are available, and the remaining potassium carbonate can be prepared by plant ash: crush the plant ash, then pour it into a wooden basin and stir it with water to make it fully dissolved, remove the foam after clarification, pour the supernatant into the pot, and boil until crystallization, you can get "ice alkali", that is, potassium carbonate.

With raw materials, glass kilns, fuel, and blowers are also needed.

Glass kilns require red bricks, fireproof bricks, and cement. The raw material of red bricks is only clay ore, fireproof bricks can be made of dolomite, and simple cement is also easy to do.

In 1756, a lighthouse in the English Channel suddenly caught fire and was destroyed, and the engineer J. Smitton was ordered to repair it within the time limit, but the logistics department of the pit father brought a batch of limestone that did not meet the quality, and Smitton had no choice but to use this batch of limestone to burn quicklime, but he did not expect that the quality of the fired quicklime was excellent. After a demerit investigation, he discovered that there was clay in this batch of limestone, and from then on Europa appeared the original cement formula.

In 1813, the Flannish civil engineer Picas discovered that cement made by mixing lime and clay in a three-to-one manner performed best.

In 1824, the English engineer Joseph Asputin used limestone and clay as the main raw materials, then added cinder and slag to mix in a certain proportion, calcined the mature material in a vertical kiln similar to burnt lime, and then grinded it to make cement. Thus, modern cement appeared.

Saga does not have a large amount of cinder or slag, but there is volcanic ash on Kyushu Island, and it is the same when volcanic ash is added.

With red bricks, fireproof bricks and cement, you can build a glass kiln - an ordinary ceramic kiln can be burned down at high temperatures, and there are all kinds of disadvantages if you dig a cave to make a kiln.

With a windmill, you can use a mechanical bellows to blow air, and Fuso's iron-making bellows at this time are pedaled, and the power does not meet the requirements.

The coke has been successfully copied by Saga's Honjima Fuji Taifu, so all the preconditions for making glass have been met, so Naohide dared to make a plan, even so, he first asked Saga to issue a letter of exemption, it is really not easy to fire glass at this time.

The four of them straightened out the entire plan according to the process and issued various explanations. During this period, Mr. Ito Genpo came to talk to Naohide, and Mr. Genpo was quite helpless, Saga wanted to make a fortune by making glass, so he set his sights on himself as a student, but if he failed or there were twists and turns in the middle, it was not a good thing. More things are better than less things, if Saga suddenly turns his face, Naohide is just a low-level shogun, and the matter is involved in the Nagasaki Commission, Naohide will definitely have no good fruit to eat. Even if it succeeds, not to mention the dirty things of grabbing credit, if it spreads, there will definitely be people who will focus on the high income of glass manufacturing, and then Naoxiu will not be good.

In the end, Mr. Xuan Pu is well-informed, and Naoxiu forgot the requirement for confidentiality, but fortunately someone reminded him.

The next day, Naohide met again with Hamuro Heinoyun, Shiba Zuo Chuan Tai and Motoshima Totai in Lan Xueliao, and carefully explained the plan, originally Hamuro Heinoyun and the three went back to discuss it and felt that Naohide's request was too much and was ready to refuse, but when I heard it today, I could still get the manufacturing method of red bricks and cement, and it seemed that the cost of red brick and cement manufacturing was not big and more credible, and the three of them hesitated again.

"There are two more conditions below."

There are also conditions, and the three of them are a little numb.

"First, regardless of success or failure, please keep it strictly confidential, and this point must be written on the oath paper; Second, after the deed is completed, I want a civilian boat, it doesn't need to be too big, except for the boatman, it can carry ten people", there are more lice and don't bite, Naohide put forward all the conditions.

The eyes of Saga everyone focused on Too Motoshima, who was a famous forger in Saga and had the most judgment on whether glass could be made, and Motojima listened to the plan the most carefully, he picked up the explanatory document and plan and read it carefully, and then nodded.

"Glass making has not been made in Fuso, I asked Naoxiujun to guide, it was difficult for a strong man, but fortunately, Naoxiujun was generous. It's just a little bit, the whole plan costs a lot, in case of twists and turns, I'm afraid we can only cut my stomach, and I ask Naohide-kun to take care of me" Hamuro Heiyuki Yun said solemnly.

"Don't cheat your father, if you cut your stomach, I can still get out of Saga", Naoxiu scolded his belly, but the sedan chair carried people, he couldn't say "Okay, you cut the stomach, I will sweep your grave every year", if he dares to say this, he will not be able to get out of this door today.

"Before you think about winning, you will lose first, and there is no doubt that the glass will be made of my self-confidence, but there are unforeseen circumstances, and Naoxiu does not dare to be too big, causing a few people to be so embarrassed, and Naoxiu is deeply uneasy. If it's so embarrassing, don't mention this matter again", who wouldn't retreat as advance, who would you scare with belly scare, can't I do it if I don't do it?

"The little fox is slippery, and it is pushed clean", Hamuro Heiyuyun scolded in his heart, but Naohide can pick and choose, Saga can't, I heard that he can make glass, and the main man Nabeshima Qizheng called the three of them, and his words were earnest, in a word, "If there is a difficulty, there is no difficulty, and there is no difficulty to make difficulties."

Yu Mu was MMP in his heart, with a smile on his lips, he turned his head to stare at Mr. Xuan Pu and did not speak, "Your apprentice, you can do it."

Mr. Xuan Pu has a lot of care for Naoxiu, Naoxiu hurriedly spoke, how can he not embarrass Mr., "Naoxiu has three hundred taels of Mitsui Zajin, and I am willing to use this mortgage to show sincerity."

In the end, it was practiced, and Yu Mu said "How can this be", and waved his hand again and again. But Naohide just took out the golden ticket that was placed on the tatami mat and disappeared in a blink of an eye.

The three of them got up and said goodbye, saying that they would make a decision on the music domain, and the third brother ran away with Naoxiu's money.

Three days later, Hamuro Heinoyun and his gang returned to Lan Xueliao with the official documents of the domain, and Naohide checked the official documents and agreed to all his requests, so the glass manufacturing began vigorously.

Naohide did not shy away from suspicion, and transferred all seventeen people from the windmill group to help, and asked Totao Motojima to be the director, and he was the guide - the head snake still has to be used, otherwise the coordination of light will not move, and Totao Motojima will be the No. 1 ironwork technician and weapon manufacturing expert in Fuso in the future, and the Saga reverberatory furnace was built by him, and the level is very large.

According to the plan, Zhixiu divided the people into four groups, one group collected raw materials and carried out preliminary processing; The second group is responsible for the construction work, and the brick kiln, glass kiln and bellows driven by the windmill can be prepared; The third group of people was formed by Totao Motoshima, and the kiln in the later period needed to be skilled, so hurry up and order the people first, and don't rush when you need it, and people can't come; The fourth group is accounting and logistics, he invited Shiba Zuo Chuan to be in charge, first according to the budget to get the money, no money to make a wool, in addition to showing sincerity, "The money is in the hands of your own people in Saga, and I am innocent."

Because Zhixiu's plan was broken down very carefully, and small nodes were set, the results came out quickly.

Twenty days later, on the 21st of May (May), the cement was successfully fired, and on the 27th of the month, the first batch of green bricks was successfully fired.

At this time, lime was used in large quantities, so cement firing was the fastest to complete, the main difficulty was the collection and transportation of volcanic ash, followed by the grinding of raw materials and clinker.

The bricks were not very technical, and the quality of the green bricks was quite good, using several larger ceramic kilns and adding cinders to the clay – the cinders were a by-product of the coke made by Fujitaio Motojima.

Because the performance of green bricks in anti-oxidation, waterproof, anti-atmospheric erosion and other aspects is significantly better than that of red bricks, Zhixiu thought about it, and it is not troublesome to water and cool down red bricks, or go directly to the green bricks, but there is no mechanical brick embryo pressing is not ideal, Zhixiu designed a pressing tool similar to a long seesaw to solve this problem - this year can only make do everywhere.

After the successful firing of the green bricks, the firing of dolomite fireproof bricks was put on the agenda - fortunately, the glass kiln that Naohide was going to build was not large, otherwise the grinding of raw materials alone would exhaust the individual.

The cost of bricks and cement is not small, but it seems that the future is not large, because of the Fuso earthquake, so the roof is mostly made of wood, and it is not necessary to build a house with bricks and cement. But the Saga clan likes these two things very much, because they can be used to build forts - the Fukuoka Kuroda family and the Saga Nabeshima family are Nagasaki Goban who assisted the shogunate in guarding Nagasaki, in order to defend against foreign ships, Saga continued to build forts in the coastal territory, the boulder fort is good, but the cost is too high, all the stones can't be repaired, and some of them can be bricks and cement, and the effect is not bad.

Since the production of cement, red bricks, green bricks, and fireproof bricks, the confidence of the whole team has increased greatly, and the three of them, Hamuro Heinoyuno, Shiba Zuo Chuan Tai and Motoshima Fuji Taio, have not put on a bad face all day long, and the phased results have come out, and they finally have an explanation for the feudal office. One day, Hamuro Heinoyun also sent back the three hundred taels of golden tickets, and apologized to Naohide vigorously, saying that he was busy and forgot, Naohide had to pretend to be confused, it was difficult to raise fish in clear water, and everyone had to compromise with each other if they wanted to do things.

With green bricks, fireproof bricks and cement, glass kilns were quickly built, potassium carbonate and various raw materials were ready, and glass firing officially began.

Naoxiu is also mixed with the society, he first found a small ceramic kiln to do an experiment, put the raw materials of firing glass into the firing pool made of fireproof bricks, put more potassium carbonate, after ignition, the pedal windmill blew violently, After a long time to open it, it can indeed be made into glass, but there are a little more impurities in it. After this success, everyone's confidence has increased a lot, and this experiment at least shows that glass can be manufactured, and how to improve the process in the later stage.

Naohide deliberately waited for more than ten days, if you want to grab the credit, this time is the best, the materials are complete and polished, the glass kiln has been tested and burned, and it can also be used, and the process has been discussed in detail with Tofu Motojima, normally, this must not come out of one or two relatives of the feudal lord to jump out and grab the credit, Naohide is an outsider, with small arms and legs, who will he rob if he doesn't rob?

As a result, Naohide and the others were impatient, and the didn't happen, so they had to inform Totao Motoshima to start firing glass.

Now don't talk about natural gas, not even gas, after thinking about it, the glass kiln built can only be a horseshoe flame pond kiln, which is a little smaller, but in order to ensure that the temperature reaches the standard, it can only be it. It is said that the earliest large-scale glass production in England was a crucible kiln, but Naoxiu did not understand the structure of the crucible kiln, so there was no choice.

In the future, in 1867, F. Siemens built the first continuous melting glass pond kiln, so Naohide built an intermittent horseshoe flame pond kiln, but there should be everything, glass melting, heat source supply, waste heat recovery and exhaust gas supply four parts are a lot, and the regenerator was also built, I don't know if Totao Motojima can remember to use it when he builds a reverberatory furnace in the future.

God bless, the ancestors are virtuous, on the 27th of June (June), the first kiln of liquid glass was successfully produced, a success, everyone cheered, and Naoxiu was also very proud, after all, this is the first time he has left traces of industrialization in this world, and how can he have his own stroke in the history of Fuso in the future.

Murata Yongmin's eyes widened on the side, and he muttered in his mouth, "I signed the secretary of Bao, I lost it, I lost a lot", Naohide was angry after hearing it, MMP, I forgot to sign a secretary with Saga, I can't say that I am involved in this matter, I still raised it myself in the middle of nowhere, who to reason with.

The glass was successfully manufactured, and Naohide left detailed technical instructions for the island, including safety regulations such as masks, the role of each raw material in the formula, the quality that mixing and annealing can provide, etc., and he couldn't help with the subsequent improvements, so he relied on the team led by Totao Motojima to slowly try to improve. However, what Naohide didn't expect was that after this incident, many Lan scholars in Motoshima and Saga strengthened their ideas of borrowing and sharing technology, which added a lot of changes to the future history, which can only be said to be the aftermath of the butterfly effect - a small step at that time, and a big change in the future.
