Skynet Architect

There is no trace of blood on the floor tiles. After all, after hundreds of years of wind and frost, there are traces of people kneeling and worshiping on the ground next to them. worship. 』』『

Looking at the traces on the ground quietly, it seems that people in Zhaojiagou have devoted themselves to firing city bricks for hundreds of years.

Back then, I believe that the entire Zhaojiagou family devoted themselves to the firing process and continued to innovate, resulting in the huge kiln factory now.

Zhao Mubai went to get the secret record. After calming down, Village Chief Zhao explained the firing process of the entire kiln to Si Fan.

This thing does not need to be kept secret, because everyone already knows it! Nowadays, there are too many modern technologies that can solve the difficulties that could not be solved at the beginning, and make better-looking wall tiles.

But that quaintness is gone.

Village head Zhao hunched over and led Si Fan through the kiln, pointing to the equipment in front of him.

"During the Hongwu period, it was the era with the most stringent requirements for firing city bricks in all dynasties. In order to build the city wall, Ming Taizu Zhu Yuanzhang had strict requirements. It was really achieved with sound and no holes." Zhao The village chief mentioned that request again.

There is a sound when knocking, but there is no hole in breaking!

This is a very high requirement for city bricks.

It is also a requirement for sturdiness.

After having this request, Si Fan visited the firing process of the city bricks.

This is completely different from Si Fan's mind.

Just making bricks requires a full seven or eight processes, although it is slightly simpler than firing porcelain.

However, when these seven or eight processes are placed on the top of the wall bricks, it is already jaw-dropping.

You must know that the number of city bricks used to build Nanjing City was hundreds of millions of square meters! This is a huge investment that only the country can afford.

However, China spent so much time and money building the city wall back then.

Most of the wall bricks on the ground are Hongwu ten years old. That era happened to be the period when the city wall was built.

The required wall tiles are also the most.

After Village Chief Zhao led Si Fan around for a while, he finally arrived at the firing site.

"This is the firing site of our kiln. Unlike the scattered brick kilns in the funny city, this is the only kiln in our Zhaojiazhuang! But it is also the largest kiln, and the production is also the most sophisticated. During the Qing Dynasty, our Zhaojiazhuang The wall bricks made by people in the ditch used to be the choice of high-ranking families in the capital. Among them, our original white bricks were all scrambled by some high-ranking courtyards. At that time, only those who wanted to order white bricks from our Zhaojiazhuang The big shots can only be ordered.

Si Fan also nodded. In the palace he saw, there were actually such miraculous wall bricks. Other wall bricks would always become very fragile and many of them were damaged in the hundreds of years of history.

There is only one kind of white porcelain city brick that has experienced a hundred years of wind and rain without any change!

Si Fan had also heard of this famous wall brick before, and now he can finally see it.

"Here are the steps before firing!" He said, pointing to a pond in front of him.

Si Fan looked at the pond. It was cloudy from top to bottom, and the bottom of the pond could hardly be seen, and no living things could be seen inside.

"If you want to make city bricks, you need to use a sieve to remove impurities. The children in our Zhaojia Village have to learn to make wall bricks from this step when they are young." Village Chief Zhao explained.

Si Fan saw that the extremely flat ground was very clean, and there was almost nothing left after being cleaned up.

But there is a hill nearby.

It is estimated that it is the impurity that was screened out.

Over time, it has changed from the mound of the year to the hill it is now.

Looking at this hill that is seven or eight meters high, you can tell how many wall bricks have been fired in these years.

"Only the clay that has been screened three times can be fired, and the material is the foundation of the city bricks!" After the introduction, Village Chief Zhao guided Si Fan to the edge of the nearby pond.

Just next to it is the cowshed, in which there are seven or eight buffaloes that are buff and strong.

Moaning, he looked at Si Fan, a stranger.

"This is the pond of our kiln. The clay that has been screened out must be soaked in the pond, and the buffaloes will be trampled and cooked in the pond. After doing this several times, only the most delicate part of the soil is added to other The blanks are made of raw materials...wait to dry before being fired in the kiln." Village head Zhao introduced these series of crafts.

But these are the most basic, and the most important things are not revealed a word. These crafts are done in every old brick kiln.

Now tell Si Fan that there is no problem, and his technical secrets are some seemingly small or even imperceptible skills.

It may be a little boy's urine occasionally spilled in the mouth of the kiln by a child! Or it could be a handful of powder that was casually thrown into a brick kiln.

This is the experience they have accumulated over hundreds of years. All success may lie in these small means.

These skills are taught by masters when they are old, and when they are about to die, they take their apprentices or sons to teach them gently in their ears.

It is also the capital of their survival.

Si Fan didn't want to know so much, he didn't want to burn bricks! He also respects other people's secret recipes.

Just followed with a smile and watched the following process.

The entire kiln mouth is very huge, and it looks like steamed buns from a distance. So it is called steamed bun kiln. There are three large chimneys above the kiln mouth.

After the explanation, Si Fan had a general understanding of this.

Of course... it's just a rough idea. The specific details are the specific operations of other professionals.

Si Fan would never do things like an outsider guiding an insider.

Looking carefully at the entrance of the kiln, after walking around for a while, he saw a gray figure running towards him in the distance. Si Fan could be sure that this was Zhao Mubai, because he was yelling loudly while running. In his hand is a thread-bound book.

"I found it! I really found it. I found the notes of my ancestor Zhao Deshan!" Zhao Mubai ran over excitedly. He took Si Fan's hand and didn't let go.

He is covered in ashes! With a musty smell, that smell makes people go crazy.

Si Fan distanced himself as much as possible.

"What did you find? What did you find! Tell me!" Si Fan said.

Zhao Mubai on the opposite side looked at his clothes, and suddenly said awkwardly: "I'm sorry, I was excited just now! I found the recipe for the white porcelain city bricks that my ancestors carefully fired back then. At that time, this kind of city bricks were very strong and the most Top-level city bricks, but even so, the amount of firing is still too small, and the rate of inferior products is too high to give up."

"Now! I finally found the notes from the year and found the biggest regret of the year! The biggest dilemma of the year!"

"That means the temperature is not enough!"
