In this way, it can be considered completely completed, and this is a big project.

A thousand slaves, after a busy night, finally dug out the pit, and then, the work has just begun.

Next.

Ying Changsheng took advantage of the dawn to come over to inspect it, and found that the pit dug out was not bad, he was quite satisfied with this, and said with a smile.

"Not bad, not bad, keep working, and strive to complete the main project within half a month!"

After that, Ying Changsheng frowned again, because this swimming pool needs to be tiled.

Porcelain has appeared in the Qin Dynasty, but the contemporary porcelain is far worse than the porcelain of later generations, and the porcelain of the Song and Ming dynasties has developed to the peak of the period, in sharp contrast, in this case.

Win Changsheng can only make some improvements to the porcelain, and then make good tiles.

Thinking of this, Ying Changsheng didn't care about being busy, he directly found the porcelain workshop located in Shaofu, and then gathered the craftsmen in this porcelain workshop, and then, after thinking for a while, he opened his mouth and said.

"Do you know how to make tiles?"

"Tiles?"

The moment I heard this unfamiliar word.

Everyone looked at each other, and they didn't know what the tiles were.

I don't understand what a tile is.

Speaking of which, at present, the porcelain in the territory of Qin is still not the mainstream, and the mainstream utensils are still those gorgeous lacquerware, and still those bronzes that represent identity and status.

In such a situation.

Naturally, it's not a big guy, I don't like porcelain.

It is really because the current porcelain is really too primitive, far less exquisite than the later generations, and delicate.

It is not as exquisite as the porcelain of the Song Dynasty in history, and the beauty of the pattern and lines, in such a situation.

Naturally, it is extremely difficult to get the right porcelain.

But fortunately, who is Win Changsheng?

He has the hang-in of the system.

Can this question be difficult for him?

After seeing Ying Changsheng's slight hesitation, he immediately opened his mouth to the craftsmen on the left and right.

"The so-called ceramic tile is to fire porcelain into thin sheets, each piece is about the same size, and then, on its surface, there is a layer of porcelain, is this difficult for you?"

"This ......"

The moment Ying Changsheng's voice fell.

For a while, the craftsmen next to them looked at each other, not understanding what the use of this thing Ying Changsheng was talking about, only to see them look at Ying Changsheng suspiciously, and then opened their mouths to ask.

"Nineteen sons, what is the use of this tile?"

"This tile is very useful, it can be used to decorate the house, to decorate the house, it can also be used to spread on the ground, of course, it can be spread in the bath, spread in the swimming pool, used for waterproofing!"

After Win Changsheng's voice fell.

Everyone on the side bowed their heads and expressed their agreement.

But the craftsmen have a new perspective.

What's more, move your mouth at the top, and break your leg from the bottom.

At this moment, it is really not easy for them to study this tile.

After all, they don't know how to fire it.

And after seeing their embarrassed expressions, Ying Changsheng figured out his own way.

His method is actually quite simple.

That is, first go through the system and find a way.

In the mall of the system, Ying Changsheng has already accumulated a large amount of national fortune value, through these national fortune values, Win Changsheng can exchange a lot, what he wants, right now, this porcelain refining technology, can be exchanged through the system mall.

I saw that Ying Changsheng easily obtained a book on porcelain firing.

Then he took the book and read it.

After looking at it a few times, Ying Changsheng felt that this book was not bad, and the introduction of technology in it was quite detailed, and then he only saw Ying Changsheng, and began to paint cats and tigers, directing the craftsmen in front of him to fire porcelain.

According to Ying Changsheng's instructions, the craftsmen did not dare to be the slightest slack, they had to use the soil first, and then make embryos, and then, according to Ying Changsheng's instructions, these embryos were carefully placed in the furnace.

Then, according to Ying Changsheng's instructions, he lit the fire.

However, when the fire is lit.

Ying Changsheng was directly dumbfounded again.

Because now, he has discovered a new problem, and this problem is nothing else.

He is because, at the moment, the porcelain kiln in the distance has been burned, the fire has been lit, and the tiles have been sent in for firing.

However, the most critical technology cannot be achieved at all.

This technique is nothing else.

That's the control of the furnace temperature!

Well, this book on firing porcelain that costs a hundred countries to win Changsheng and redeem it from the system ignores an extremely important issue.

This question is nothing else.

That is, ignoring the problems of the times.

Many things that were very common in later generations, in the Qin Dynasty, were not at all.

Like, what kind of furnace was used to fire porcelain in later generations?

The furnace used to fire porcelain in later generations is a serious electric furnace, which has good fire control technology, and can also adjust the firing temperature at all times, so that the porcelain can be fired successfully under the appropriate temperature!

But here's the problem.

At this time, Ying Changsheng has no technology in his hands at all.

This kind of electric furnace, given him a few hundred years, he will not be able to build it.

Without an electric furnace, it is possible to make up for the gap by backward means.

But the problem is that Ying Changsheng doesn't even know how high the temperature inside the porcelain kiln is.

In such a situation.

How does he make porcelain?

I saw that Ying Changsheng looked embarrassed and looked at the craftsmen next to him, but the matter had come to this point, and he had no choice but to bite the bullet and open his mouth to the craftsmen on the left and right.

"Then burn, burn this stove out, let Ben Gongzi see it!"

"No!"

The craftsmen next to him did not dare to slack off in the slightest, they all followed Ying Changsheng's instructions, lit the stove there, and then carried out firing, which lasted for several hours, when the tiles of the first furnace were properly fired.

I saw that the craftsman walked in front of Win Changsheng, and then told Win Changsheng that the time had come.

Seeing this situation, Ying Changsheng directly ordered the fire to be extinguished.

After finishing the flameout, Ying Changsheng did another thing again, that is, waiting.

Well, after the porcelain is fired, it needs to be naturally cooled.

Of course, it can also be cooled without natural cooling, and can also be achieved by pouring some cold water directly.

However, this can easily lead to the shattering of properly fired porcelain.
