Rongcheng is surrounded by rivers on three sides, and one side is close to the lake. There is the South Juma River in the north, the Daqing River in the east, the Baigou River passes through the north and south from the east of Rongcheng County, the south is close to Baiyangdian, and the Ping River flows through Rongcheng County in the west. It sounds like it is quite rich in hydraulic resources, but it is indeed the same: it is just that the Nanjuma River in the north often has a flood every 20 years or so; The mouth of the black dragon in the southwest is named because of the flood when the flood was raging, and it is said that some people saw the black dragon haunting.

At present, there are several large waterwheels on the embankment of the Nanjuma River, and the river is rushing down, with the huge water wheel rotating again and again, which is a new sight from a distance. However, many people do not understand that this water wheel does not seem to be used to irrigate the fields, because when you look at the large row of stone houses on the embankment, there are no ditches leading to those fields that are at least a few hundred steps away from the embankment.

Someone asked about this, but the locals of Rongcheng raised their chins: "Let's figure it out, are you still staying here?" That was ordered by Duke Ding, understand? Today's royal pen personally gave 'white-clothed bachelors, unarmored flying generals' Ding Gongyi, and the things he figured out, can there be a difference? ”

If it is said that Ding Gong is not very easy to understand who it is, but when it comes to the royal pen himself, the questioner suddenly realizes: "Ding Rongcheng? It turned out to be such a person! It's not me, isn't this the hometown of Duke Ding? Offended, offended! Or don't know, the locals naturally have something to talk about, and they touted Ding Rujin's deeds one by one, and they all won applause.

The broken flag is in front of the Ding Mansion, and there are eight bright yellow words on it: Loyal to the country, brave champion of the three armies!

The people of Rongcheng are saying that if the Ming Mansion goes to visit the Ding family, it will become a kowtow worm: the flag in front of the house is the royal pen, worship or not? Go inside, go into the living room. What is offered on the incense case is that when Ding Rujin resigned and returned to his hometown, he wrote "a bachelor in white, a flying general without armor", worship or not? If Ding Gong is interested, he meets the magistrate, divides the host and guest to open his robe and sit, and his waist is out of the city to fight that day, and the emperor unties the jade belt for Ding Gong after he unties, worship or not?

It was said vividly, as if it were true. It's just that in fact, in the entire Rongcheng County, how many people are seeing the county master?

Did Ding Yi stand proudly on this journey and tie the jade belt given by the emperor around his waist at all times?

Who's going to take it seriously? Whether it is the county prince or Ding Gong, although they are in Rongcheng. But it is far away from the small people of Shengdou, and everyone has tea and dinner. It's just a matter of talking.

In fact. Even the stone houses on the embankment of the Nanjuma River were hardly accessible to anyone who could go in and take a look.

Otherwise, there will probably be no such topic as Ming Mansion worshipping Ding Gong, if the county prince really wants to visit Ding Yi, he will also come to the river embankment, not to the Ding Mansion in the county seat. Since the resignation of the Jingshi. Ding Yi has spent most of his time here in the past few months.

"Sandstone, soda ash, feldspar, dolomite, limestone, miscanthus salt, it should be right!" At this time, Ding Yi was in a stone house by the river embankment. Scratching his head and meditating, he patted his thigh for the last time, and asked Liu Tie on the side, "Is it proper for you to invite the porcelain kiln to watch the fire?" ”

Liu Tie's dog-legged face was so bitter that he was about to cry: "It's definitely proper!" Last night, last night......"

"What happened last night?" As soon as Ding heard this, he felt that something was wrong, he glared, and the murderous aura sharpened in the tens of thousands of Varat Iron Rides made Liu Tie only feel a chill down his spine, and only then did he realize that he had leaked his mouth.

At this time, he had to report honestly: "Last night, Xiao Yi and a few of them felt that Mr. was too good to the fire watcher, a lowly person like a dog, holding a shelf, maybe it was a problem he deliberately made...... At night, Xiao Yi and the others covered their faces and pretended to be Mr.'s enemies, so they went to clean up the fire watchman, but they found nothing. ”

Ding Yi shook his head, he didn't even have the interest to reprimand Liu Tie and Xiao Yi, he just waved his hand to let Liu Tie go down, and muttered to himself: "This is impossible!" It is impossible to burn porcelain kilns without 1,700 degrees, how can it not burn glass? What went wrong? ”

To create a seamless barrel, you have to have a drill bit, and the original machine tool with hydraulic transmission alone is not enough, and how to drill out the barrel without a high-hardness drill bit? So it involves steelmaking, but there is no thermometer, to make high-carbon steel, tool steel, even if someone remembers the method and formula of steelmaking, it is in vain, it depends entirely on luck.

Therefore, it is very important to look at the fire, in addition to the extreme YY, before the emergence of thermometers such as radiationpyrometers that do not need to directly contact the molten steel in the furnace, steelmaking is to look at the fire to determine the temperature in the furnace.

And Ding Yi didn't have the luxury of using a furnace molten steel to judge the level of the fire watcher.

So according to his thoughts, if a fire master can accurately identify the flame changes within 600 degrees, then at least it is more reliable, and according to Ding Yi's memory, it is a mercury thermometer, which can test the temperature difference between minus 30 degrees and 600 degrees.

In other words, he had to have a mercury thermometer to avoid wasting molten steel because of the poor level of the fire watcher. As for the scale of the mercury thermometer, as long as a glass of ice-water mixture and a glass of boiling water, the scales are marked after being placed separately, and the rest is a mathematical problem.

In short, you have to make glass first.

And as long as the glass is made, the grenade can be changed to the original hair pull, instead of lighting it with an open flame! Originally, the M18 wooden-handled grenade in history was a steel pipe filled with glass powder, and a haired copper wire was rolled into a ball and placed in the glass powder, one end of the copper wire was connected to the fire rope, and the other end was connected to the fuse and sulfur, and the friction between the copper wire and the glass powder was used to ignite the fuse and sulfur.

Therefore, glass has become a problem that Ding Yi urgently needs to solve now.

But now the problem is that there is no liquid glass that can be blown out!

In fact, Ding Yi has a misunderstanding of memory here, or that this is not his specialty, and many things are just taken for granted.

The firing temperature of blue and white porcelain in the Yuan Dynasty was only between 1,100 degrees and 1,150 degrees; Originally, in history, the five-color plate of the Ming Dynasty only reached 1,200 degrees; Originally, Jingdezhen, thousands of years after the modern era, was about 1,300 degrees of kiln temperature.

And the fire-watching masters that Ding Yi asked Liu Tie to find, although the kiln built by Ding Yi is also considered to be the top level of this hourly worker, it is unlikely to exceed 1,200 degrees. Therefore, glass preheating and sintering are not a problem, but it is impossible to melt, that is, to make it form a uniform, bubble-free, and liquid glass that meets the molding requirements. That's a normal temperature of 15 to 1,007.

Before Ding Yi could come up with a reason, Du Ziteng's voice sounded outside: "Senior brother, you better let the younger brother go in, it's best to let Mr. go back to the county seat to have a look...... "Du Ziteng, who can be left by Ding Yi's side, is definitely a talent, his ability to do things and the stability of his life, he is definitely many times stronger than Liu Tie's dog-legged character, and there is no way to get him, there are not many things to come to Ding Yi to go back."

Ding Yiye also threw down the charcoal pen, raised his voice and asked, "What's the matter?" Come in and say. ”

"The master and the little master quarreled." Du Ziteng reluctantly reported. The origin of this incident is that those students of Thunder Academy who live in the county town Ding Mansion, there is a child named Ding Junyue, who beat the little son of the county master's family, and the little sons of the county master also beat Ding Junyue, Xie Yucheng is the teacher on duty, and immediately led someone to snatch Ding Junyue back.

But back in Dingfu, Liu Yiyi wants to rectify the children who beat people, since ancient times, children fight and beat their own children to relieve their anger, it seems that this is what they do; But instead of letting Liu Yiyi move the child, he also brought more than a dozen nurses to find the bad luck of the county master, Du Ziteng smiled bitterly: "The little master said that 'the dog official is bullying, and the sword of the woman is not good?'" Shi Niang was very angry when she heard this, but she asked, "It seems that this house is a boxing gym opened by Rukai." Senior Brother Shichang persuaded there, but the disciple really couldn't, so he had to come to find Mr. ......, "Senior Brother Shichang is Wang Yue Wang Shichang."

What can he do if Du Ziteng has the ability? Talking to either side is not necessarily pleasing to anyone.

Ding Yi felt a splitting headache and sighed: "Maybe I'm too anxious, maybe this academy was started too early!" Alas, prepare the horses, prepare the horses, I'll go back. "Because of the dozens of children who were sent to study in the former Jinyi Wei Baihu Zhang Tianci, who was transferred to the experience division, Ding Yi felt that putting a sheep was a release, and putting a group of sheep was also a release, and he also collected some orphans and children of fallen soldiers in the civil fort, a total of more than 300 people, preparing to build a academy in Rongcheng, at this time the academy has not yet been built, so let these children live in the expanded Ding Mansion, think about it are all children about ten years old, which is the role of An Sheng? From time to time, something always happens, and Ding Yi is climbing the technology tree and it is not very smooth, and he feels a headache when he listens to it.

As soon as he got on the horse, Ding Yi listened to Xiao Yi shouting from afar: "Sir! Mr! Ran to him, but asked, "The glass can't be burned, those craftsmen said that although it can't be burned into water, it is also soft, it is better to carve some iron molds and press them into pendants such as jade Buddhas, and it is better to sell them for some money and silver." The disciple thinks it seems to be feasible......"

"How many bucks can you sell? If you have the ability, go back to the county with me, and go and tell your wife yourself! Ding Yi angrily vetoed Xiao Yi's suggestion, if it is made into a glass mirror, it is fine, at present, these sintered waste materials that cannot be melted are made into glass ornaments, who will want it? I can't talk about it if it's crystal clear, I can't say it if I want the color, I'm afraid that I won't be able to sell the price of firewood to burn them, "What I told you last time, change it and improve the outlet, you continue to try." Tell those craftsmen, don't think about those crooked ways, and burn this glass into a liquid form is the right way. ”

"Disciple understands!" Xiao Yi replied simply, but the next sentence made Ding Yi almost fall off the horse, only to hear him say, "Just tell them, if you can't burn it, you will fuck kill his whole family!" (To be continued......)
