I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

The toilet is a good thing. Although such a large piece is not easy to burn, it means that it takes a long time. In fact, this thing is easier to handle than tableware.

Because I'm not afraid of it being thick!

Even if it is made thin, I am afraid that the bearing capacity is not good enough!

After all, it is a toilet. If the ceramics are broken, it may not be as simple as popping an asshole, and it may really be fatal.

And the most important thing is that after Liu Tan designed the shape of the toilet, he was worried about the material, so he went to tinker with ceramics.

Now ceramic tinkering is out, and the toilet can also be burned, but there is still one most important thing that has not been resolved-the water in and out system.

Even if there is no running water now, we have to be equipped with water tanks and water in and out systems.

The most important thing is that this thing will definitely be useful after Shuofang City is rebuilt, so it's better to do it in one step.

In fact, the internal structure of the toilet tank is not particularly complicated, such as water inlet pipe, water outlet pipe, water plug, float ball, water release button and lever.

Oh, yes, there is also a seepage pipe, which is said to prevent the toilet water level from being too high.

It's just that this thing should be aimed at tap water, Liu Tan thought about it and finally added him.

People, always have a little dream, what if we can get running water in the future?

Liu Tan thought about the design while thinking. First, the function of the water inlet and outlet water plugs and the floating ball is to control the gate of the water pipe channel. The water outlet plug should be connected with the button to ensure that the water outlet can discharge water when the button is pressed, and then When the water level drops, the float ball will drop together, and at this time, the water plug of the water inlet will be opened as the float ball drops.

This is basically all the water inlet and outlet links of the water tank. I have to say that it is quite simple, probably the kind that people who know how to read it can remember it, but people who don’t know it can’t think of it.

After drawing this whole set, Liu Tan began to think about a very important question - what should be used to make the water plug?

First of all, the water plug must be able to completely fit and seal with the toilet inlet and outlet, and there must be no water leakage, otherwise it will be too troublesome to waste water resources.

It’s just that there is no rubber these days, and even the planting of rubber in later generations is very late. Now rubber is probably still in South America. Even if rubber evolved later, the rubber tree may still be the original species now.

Liu Tan thought about it carefully, and felt that it was not particularly difficult to solve. The water plug can also be fired with matching ceramics, but a certain margin needs to be left, and then beef tendon is wrapped around the ceramic plug. It should be possible to treat it with a waterproof material, such as glutinous rice water.

The only thing to worry about is that it will not be used for a long time in a humid environment for a long time?

But so far there is no better solution. The only thing that can be done is to make these accessories replaceable. If it is really not easy to use, just replace it.

Changing a faucet is easier than changing a toilet.

When thinking of this, Liu Tan suddenly realized that in the end, maybe the money from selling toilets is not as good as the money from selling water plugs?

Generally, the smaller the size, the more lucrative the profit, but the larger the size, the higher the cost.

However, the target of the toilet in the early stage is not ordinary people, because now only the craftsmen here can make it, not to mention that he can't share the recipe for this kind of thing, even if he shares it, there is no one who can make it.

As a result, the output will definitely not increase for a while. Liu Tan's original intention of making toilets is just for the convenience of his own life. If he wants to make it affordable for everyone, he must first reduce costs. Such an environment.

In this era without running water, flushing toilets is equivalent to requiring a lot of water resources. It is good for ordinary people to have wells in their homes, but it is annoying to carry them every time. If there is no well, it is the kind for public use. , It’s just that the amount of water used can exhaust people to death, so I just carry water and flush the toilet every day and do nothing else?

So this thing is basically exclusive to the nobles before the infrastructure and people's livelihood are improved.

Liu Tan was thinking wildly about these things while sorting out the things that needed to be done so that he could do them well.

Because there is no plastic these days, and metal is too easy to be corroded, there will definitely be problems if it is soaked in water for a long time. Liu Tan simply made ceramics except for the floating ball, and other places such as water pipes that can be made of ceramics.

If the cost rises, it will rise. Anyway, if you can afford it, you will not be short of money.

As for the floating ball, it’s actually not difficult. You can just use the pork belly, but you just need its buoyancy. As for whether it can be used for a long time, you don’t need to worry about it. At worst, you can continue to sell accessories!

After Liu Tan finished writing, he couldn't help but feel that he was getting closer to a profiteer.

However, it was precisely because he was working on the toilet that the craftsmen under him had a buffer period. Instead of rushing to burn the toilet, they could first burn the tableware that Liu Tan needed to give away.

Adhering to the principle that precious things should not be given away randomly, what Liu Tan gave Liu Ju was also a set of tableware, but without the tripod, there were only simple wine cups, bowls and basins.

As for the pattern, it is very easy, just copy it to Liu Che, because there is no tripod, so if the "Mount Tai" that is more likely to cause controversy does not exist, there will be no big problem at all.

The porcelain for Princess Yang Xinchang and Princess Danglichang was even simpler. It was just a few wine cups or bowls, and there were no patterns on them, just the original appearance of Qianfeng emerald color.

Liu Tan also sent a message asking the two eldest princesses to forgive him, because he really didn't have time to draw.

But in fact, even if he didn't say it, the two eldest princesses didn't feel that they could get the same thing as the emperor.

At this time, anyone who has seen ceramics knows that the painting on the emperor's tableware was drawn by the king of the north himself, and all of them lost their minds for a while.

But after seeing the porcelain without any pattern in the hands of the eldest princess, they were moved again. Even if they couldn't get the same style as the emperor, such plain porcelain would do.

After all, rare things are precious, even if they don't need to be placed at home, it's still a face.

So after the two eldest princesses, Liu Tan welcomed Li Buyan and Wei Buyi who came to the door hand in hand.

He can understand Li Buyan's visits. When this guy didn't come to Chang'an before, he was also a well-known local dude. Dude, he wanted all kinds of new things.

However, Wei Buyi was very surprised: "You came for Princess Yang Xinchang?"

Wei Buyi rubbed his hands and said, "No... no, just if His Highness can let me line up, I will pay for it."

Liu Tan was a little surprised: "Buy it for yourself?"

Wei Buyi said in a low voice: "Eldest Princess said before that we are all grown up and we should divide the mansion, so I thought..."

Liu Tan understood in seconds, probably because Wei Buyi was thinking carefully, his elder brother is the lord, he and his younger brother are nothing, but the younger brother is still young and has not yet married, Wei Buyi is not too young and it is almost time to say goodbye , now it's not embarrassing.

Owning porcelain would not elevate Wei Buji's status, but at least it would give him a place to stand.

Liu Tan chuckled lightly: "What should I treat as a housewarming gift?"

Wei Buyi's eyes lit up immediately, and then he hesitated: "This... the eldest princess only has two pieces..."

Liu Tan chuckled: "I can send it to whoever I want, does it depend on the person's face?"

To be honest, even if Princess Yang Xin is his aunt, she is inferior to him in terms of identity. According to seniority, he respects Princess Yang Xin, but he absolutely does not accept life guidance. Of course, only Yang Xin is the only one among Liu Che's three sisters. The eldest princess can leave a name in history, and Liu Tan believes that she is knowledgeable and interesting.

Wei Buyi was very excited, and Li Buyan at the side began to circle around Liu Tan: "Your Highness, I don't want a set. When you are cooking for him, just get me a pair of chopsticks."

Liu Tan: How can you think so hard?

Ceramic chopsticks, he never thought of getting them!

Chopsticks are too smooth to use, and they are easy to break if they are not handled properly. The most important thing is that ceramic chopsticks are too heavy. After eating this meal, my hands may break from fatigue.

Liu Tan said angrily, "Here is a plate for you."

Li Buyan was actually very happy: "Okay, okay, the plate is also very good."

Liu Tan was helpless, he made some calculations and said, "It's just right, I'll give you one set for Busu, one set for Huo Xiang, and a plate for you. After this batch is cooked, I'll burn it with other things."

Li Buyi was stunned: Why is it just a plate to him?Everyone else is a whole set!

But it was said to be a complete set, but in fact it was just a set of tableware for one person, so it was impossible for him to let these people pass Prince Liu Shi.

After finishing these sets, Liu Tan started to have toilets burned.

Because the toilet is also a new thing, it needs a little experimentation, and it needs to be tested for load-bearing and waterproof after firing.

Liu Tan thought it would be nice if he could make the finished toilet before leaving.

However, when he fired the toilet, because he no longer fired porcelain, people who wanted to buy it couldn't buy it.

Originally, some people thought they could come to ask for it, but Liu Tan didn't burn it anymore, and I don't know what to do again.

This has led to the fact that no matter who has porcelain in their hands, the value of the porcelain will soon be fired to the sky.

After the toilet was finally fired successfully and the experiment was completed, Liu Tan happily took the toilet to meet... Liu Shi.

To be honest, he can give away other things, but this time... it feels a bit unreasonable.

He was afraid that if he went in with someone carrying the toilet, Liu Che would throw him out with the toilet.

So let's start with Liu Ju first, and test his acceptance.

Liu Ju sat on it and looked at Liu Tan with a half-smile and said, "A rare visitor."

Liu Tan's face was paralyzed: "Don't learn from your father, right?"

Liu Ju laughed: "You, why is it more boring to go back to Beijing this time than before? I used to go to Zhuangzi anyway, but now it's fine. I don't know what Tianmao is doing in the palace."

Liu Tanxin said that he used to go to Zhuangzi because he couldn't make inventions in the palace. It was a trivial matter to be seen by others. What if there was something dangerous and the palace was blown up?

Liu Tan coughed lightly and said, "It's very cold, and it's cold outside, so the palace is enough for me to play."

Liu Ju snorted softly: "You are still in the mood to play, are you not worried about what I sent someone to tell you?"

Liu Tan: "Huh?"
