Rihito smiled and said, "Very good! ”

The potters looked at each other with a little disbelief from the big eyes and the small eyes, and then Rihito said, "I didn't talk about it at first, it doesn't matter if a hole leaks a little, just let it leak a little bit." But the two-hole ceramic tripod can't leak a trace of air. ”

"Oh!" Only then did the potters know that this was the case.

At this time, the copper smelting masters also made the two copper pipes required by Liren, although they were not seamless, but the copper pipes knocked out by a hammer did not leak at all. Liren connected the short one to the round hole in the waist of the ceramic tripod and then sealed it with clay, and the long one was connected to the ceramic tripod at a high place and the ceramic tripod at a low place. After this was completely connected, Li Ren ordered someone to take sulfur, nitrate, and a small amount of charcoal and put them in a ceramic tripod on a high place.

After placing it, Rihito had a wooden animal blower attached to the short copper pipe. With everything ready, Liren immediately lit the charcoal in the ceramic tripod on the height, and after a while, the burning of the charcoal led to the burning of sulfur, and bursts of white smoke came out of the tripod. Liren hurriedly asked people to cover the lid of the ceramic tripod, and then the white smoke could not come out at all.

Rihito hurriedly ordered the animal power blower to start running, so that the white eyes that emerged could go to the dings below. After a while, white smoke also came out of the dings below, and Liren hurriedly asked people to water the copper pipe connecting the two ceramic tripods, and then water the ceramic tripod cover below.

Half a day passed, Li Ren ordered people to hurriedly open the ceramic tripod on it to see if there was still burning sulfur, and as soon as the ceramic tripod on it was opened, he saw that there was no smoke coming out of it. Li Ren hurriedly asked people to open the ceramic tripod below, only to see that there was a layer of yellow liquid at the bottom of the tripod. Everyone felt very novel, Li Ren just smiled and didn't say anything, just asked people to use a ceramic spoon to fill the liquid in the Ding in a ceramic bottle little by little, and instructed everyone: "No matter what the situation, the yellow water in the bottle, you must not touch it with your hands, remember this order." Everyone wrote it down.

Liren knew that the contents of the bottle were dilute sulfuric acid, and he had to wait for further purification. Liren hurriedly ordered the ceramic masters to fire two more basin-like big tripods, and the lids on these two small tripods must have holes, and the masters went to do it according to Liren's instructions.

Li Ren also instructed the coppersmiths to make thin copper pipes, and also to make the copper pipes into a spiral shape. The masters looked at him with questions a little puzzled, and Li Ren smiled and said, "I'm going to turn the yellow liquid just now into colorless, and you don't need to know the rest now." Now the masters didn't ask anything anymore, they all lowered their heads and hurried to go about their own business.

Li Ren returned to his study, and at this time Zhang Yue came to ask, "Lord! What are you doing here? How can it be west and east? ”

Li Ren was looking at the "Emperor's Inner Canon" and raised his head to see Zhang Yue coming, put down the book in his hand slightly, and said, "Hehe! It's not that I'm going to go east and west. It's that I'm going to make things that I'm going to make using what I'm making now, so you feel like I'm going east and west for a while. But you're here, and I just happen to have something for you to do. ”

Zhang Yue was relieved after listening to Liren's explanation, and immediately replied: "The lord just commands!" ”

"It's not a big deal, it's just that you asked someone to buy me some anhydrite." Rihito said lightly.

Zhang Yue still has a little research on drugs now, and immediately replied: "I don't know how much the lord wants?" If it were less, we would still have a little bit in our arsenal. ”

Rihito raised his head and said, "I want a lot this time, and I want a big piece, not a small piece." But you can get me a pound or so from the drug warehouse now, and I just happened to do the test. Zhang Yue nodded and went out.

Two days later, he went to the steel mill again, and in the prepared room, he placed two small ceramic tripods on the table, one tall and one short, but this time the tall ceramic tripods were placed on an iron shelf. Then Li Ren ordered someone to bring a wooden sink, and then connected the finished copper pipe to the high ceramic tripod, the middle part of the copper pipe was placed in the sink, and the other side was just connected to the ceramic tripod below.

Li Ren poured the yellow liquid made two days ago into the small tripod above, and then poured some water. Then under Xiaoding, he ordered someone to bring a made ceramic alcohol lamp, and after lighting the alcohol lamp, the liquid inside Xiaoding began to tumble after a while. Li Ren waited, observing the situation of the copper pipe from time to time, about half an hour or so, there was already a little liquid in the small ding below that was not yet transparent.

In this way, Liren obtained a small amount of sulfuric acid at a very high concentration, but this was only a preliminary test. In the future, there were many places where sulfuric acid was used, and Li Ren thought about it and finally planned to use the lead room to make sulfuric acid, but the problem in front of him was that a large amount of lead required a lot of silver money to buy.

But now these sulfuric acid to make alkali should be enough, the next day Liren began to make alkali, the anhydrite from the drug warehouse has been let Zhang Yue take it, Liren hurriedly asked people to roll the anhydrite into powder for backup.

Someone took a ceramic basin, Liren poured the salt he had made in the past few days into the basin, holding a wooden board, Liren poured sulfuric acid into the basin while stirring, and slowly the salt in the basin melted and mixed into the sulfuric acid.

Holding the newly obtained sodium sulfate, Rihito began to get a little excited. But this was only the beginning, and then he poured the same amount of charcoal and limestone into the porcelain basin, and white smoke began to rise from the basin, and Rihito hurriedly retreated to a touch to watch and wait.

In the end, there was no more white smoke coming out of the basin, and Rihito hurriedly ran over to look, only to see that the rest of it was black ash. He immediately poured them into the prepared large wooden barrel, stirred them well, and then poured them into a large cauldron and began to boil the water. When the water gradually boiled, layers of thick white powder appeared on the side of the pot, and Liren carefully ordered someone to hang it out for later use.

Everything was ready, Rihito finally sighed, and from time to time it occurred to him that this method of extraction was really not as simple as his own method of plant ash. However, the hands-on practice has inspired the people around me, and the textbooks in the base camp have good physics and chemistry textbooks.

This time, Li Ren came to the specially set aside furnace, poured the smashed white stone powder into the large crucible, poured the anhydrite powder into it, then stirred it thoroughly, and finally poured in alkali and limestone, and then sealed the furnace and lit it.

After several days and nights of burning, the temperature of the furnace finally reached the required level with a sufficient supply of fuel. Rihito asked the furnace door to open the furnace door and saw that the crucible inside the furnace was already viscous liquid, and he used a steel rod to reach into it and stir it before taking it out. When the contents of the steel rod cooled, Rihito realized that this was the clear glass he had worked so hard to get. However, there were obviously impurities on it that had not been melted away, so Liren hurriedly ordered someone to find a little alkali in it, and then sealed the furnace and added fuel to continue to raise the temperature.

Zhang Yue ran over curiously and picked up a piece of transparent object that Liren had knocked off just now to look at it carefully, and asked Liren: "May I ask the lord, is this glass?" ”

Li Ren looked at Zhang Yue with a question mark, and then looked at a few ceramic masters who were beside him. I saw the ceramic masters say: "Big island master, this should be glass!" ”

Liren said: "If you are serious, it should be the same thing as the glass, but this is more advanced than the glass. Speaking of this, Liren suddenly understood something, and asked the ceramic masters: "Do you know how to make glass?" ”

The ceramic masters smiled and said, "Hehe! Enlightened Island Owner, we will make glass, but we won't make transparent glass like you. ”

Li Ren suddenly rolled his eyes, and said helplessly, "Why didn't you tell me earlier?" It's better than me being ruthless and upside down alone. ”

"Hey, hey! I waited for these subordinates, and when I saw the big island owner, I didn't know what to go up against. I only saw that you seemed to be alchemy, so I didn't dare to disturb you, who knew that you were making glass. The ceramicists looked at each other and said.

A ceramic master said to Rihito: "Lord Oshima, the white noodles you made in those days seem to have been seen somewhere, but he used plant ash, not as white as you made." ”

"Yes! I remember where you've seen the yellow liquid you've made, but not in the back of your process. A ceramic master also echoed it.

At this time, Liren was completely speechless, he had been busy for many days in vain, and it turned out to be something made by everyone. Ay! Failure. But luckily, this is the most advanced way for me, and only I can do it now.

At this time, Li Hai didn't see him for many days, and he also patrolled here to see Li Ren Zheng**, and said a word: "Lord, who is doing what these days, I am familiar with that smell, I used to smell it when I was a beggar, and I looked for it, it turned out to be a Taoist priest refining what pill I don't know, and the smell is the same as what I smelled in the past few days, so bad!" ”

Liren is now dead, and the sulfuric acid that he and his brother have been looking for has long been able to do it, but he is just lonely and unheard.

Although it is more depressing now, a pot of glass is already in the refining furnace. Besides, glass must not be as good as glass, and glass is a special item for the royal family, and ordinary people can't afford to consume and dare not use it. So now let's see if our own method can only make glass that is better than glass, so that rich people can use it.

With this in mind, Rihito quietly guarded the furnace, constantly asking people to fill up the fuel charcoal to ensure that the temperature inside increased. Another half a day passed, and Li Ren ordered someone to open the furnace door, and once again put in the steel rod, which was much more diluted than the original glass liquid. Li Ren immediately asked someone to hand over a hollow steel rod, and with a slight stirring, he withdrew the steel rod. One end of the steel rod was already wrapped in a large lump of dark red glass. Rihito immediately blew at one end fiercely, and kept spinning the hollow steel rod, and after a while, the end stained with glass gradually bulged like a candy blower. The eyes of the people around him suddenly straightened, and Lehi asked incomprehensibly, "Lord, what are you doing here?" ”

Rihito didn't dare to open his mouth and continued to blow into the, and after a while, he felt almost done. Stop blowing, gently press the bottom of the blowing bubble on the flat stone slab, and the bottom will immediately become a flat bottom, and wait for the solution on the steel rod to cool slowly. Rihito asked the craftsmen to take out the prepared steel stone and draw a circle at the place where the steel rod was attached, and when he took it gently, a long-necked transparent bottle appeared in front of everyone.

Rihito wiped the sweat from his head, took the bottle that was still a little hot and looked closely, there were still a lot of bubbles on the bottle. He said softly, "Finally it worked." ”

The people around looked at the bottle in his hand curiously, and then Zhang Yue took the initiative to say, "Can the lord let me take a look." ”

Liren said: "Take it and see if this kind of thing can be sold for money?" ”

Zhang Yue took it excitedly, looked carefully up and down, left and right, and finally said honestly: "Now this thing has too many bubbles, and the shape is not very good, if you sell it for money?" In my estimation, the material itself should sell for some money. But there is a high probability that even the cost will not be recovered. ”

Liren's confidence was suddenly hit a lot, and then Zhang Yue looked at it and said: "If you can do kung fu on the shape, this kind of thing can make a lot of money." ”

At this time, Li Rencai said with a smile: "Hehe! It doesn't seem to have been done in vain. ”

At this time, a pottery master interjected: "Big island master, how can this kind of thing look like the pseudo-jade refined by Taoist priests?" After speaking, the pottery master looked at Liren and said: "But this is much better than the pseudo-jade refined by Taoist priests, they don't have people refining transparent jade." ”

Listening to this master, Liren's heart was beating up and down. I took a big breath and thought to myself, "Damn! Who said that ancient China could not make glass? If I can go back, I must tear his mouth apart. Thinking of this, Liren said to the potter with a little depression: "Can you blow out the bottle like I just did?" ”

The masters looked at each other and said, "We haven't tried this yet, but we can try it." ”

One of them said: "May I ask the big island master, according to me, there are too many bubbles in this kind of thing, if you really take it out and sell it, others will definitely think of fake jade." If that's the case, it won't be long before there are imitations. ”

Liren suddenly glared and said, "Will there really be?" ”

"There will definitely be," the potter replied affirmatively, and after a pause, he added, "But if you can remove the bubbles in the middle, then no one will be able to imitate them." ”

Li Ren immediately said confidently: "No problem, but from today onwards, you masters will be in charge of the manufacture of bottles." Just try to make the bottle look good. ”

Several potters had long wanted to try this new thing that could make utensils, and they nodded their heads for sure.

Seeing that the masters had agreed, Rihito immediately walked to the refining furnace, picked up the solid steel rod just now and began to stir the glass liquid inside violently, and made people fill it with fuel.
