"Now you immediately go and ask a few points:

First, who made the mud bricks of this brick, where the mud was used, how to stir and add water, and a series of air-drying conditions, all recorded.

Second, the No. 6 kiln was investigated and summarized from the structure to the placement of bricks, to the addition of coal, and then to cooling.

Thirdly, after summing up, immediately start the second firing. ”

"Hey...... The villain goes now. ”

Liu Laoshi's black face and yellow teeth turned white, and he didn't smile too happily.

As an old craftsman, he understands too well how good the quality of such bricks is, and with such a brick city wall, he is not afraid of being attacked head-on.

Seeing Liu Laoshi running fast, Zhu Gaoxuan called Li Yuan again and asked him to quickly arrange for the scribes to help the craftsmen make records.

Zhu Anlan didn't break a brick, his face was a little red, he was holding it hard, and he was also ashamed.

He hammered a brick before, and he was mocking.

He changed another brick and smashed it hard.

Click......

Broken again.

Bang......

It's broken again.

Then he wanted to go with other bricks, even if it was a farmer picking watermelons.

And Zhu Gaoxuan's ears moved when he heard the "bang", and his footsteps also moved.

At this time, the brick was broken into three pieces, and there were only three cracks, and they did not break.

He crouched down and picked up a large piece of shards with each hand, and then slammed them together with a dull "thud...... Bang ......" sound.

"Haha...... Such bricks are hard enough to build a house.

That one...... That ......"

Just when Zhu Gaoxuan couldn't name him, the short 'black' who followed him reported his name with interest: "Villain Wang Tong"

"Wang Tong, remember this kind of brick, what Liu honestly does, you also do it."

"Okay, villain, let's go."

Wang Tong also turned his head excitedly and ran out, now there are two kiln bricks that can be used, which is a good result.

Wang Tong walked away, and Wu Yuping leaned over again, waiting to find the bricks that could be used in the third kiln.

At this time, Zhou Zhengxiong in the distance shouted loudly:

"Your Highness, come and take a look, this brick is not bad."

As soon as his words fell, the Blue Tiger also came with the same good news.

The bricks fired this time may not have a high yield rate, but each kiln has a small number of bricks that can be used to build a house.

However, Zhu Gaoxuan still did not produce less red bricks as he wished.

There were cyan, black, brown, gray, but there was no red that he was familiar with in his previous life.

There are still too many things to improve in this brick kiln.

Ten brick kilns, each brick kiln can be loaded with tens of thousands of these large mud bricks, and the total number of bricks is only 100,000; There are 300 workers in the kiln and 2,000 workers in making mud bricks.

It's just a little more than an hour that all the bricks have been taken out, but the inspection time is a little longer.

According to the instructions of experienced masons, as long as you use the strength of a bucket of water to smash the bricks, the bricks are not bad and are qualified bricks.

As for how to calculate the strength of this 'bucket of water', Zhu Gaoxuan doesn't know, and there is no need to know.

Just pick out the qualified bricks.

It was noon as soon as it was busy, but the average person in the Ming Dynasty did not have the habit of eating lunch, and they still had to work when they should work, so Wu Yuping, who had counted the qualified bricks, came to him.

"Your Highness, it has been counted clearly, because it is the first time to burn bricks, there is no experience, and the pass rate of red bricks is less than thirty percent.

Among them, there are only 972 brown bricks specially selected by His Royal Highness, which is very rare. ”

"Hmm...... There are more than 900 pieces that are already very good, proving that brown bricks are not accidental products, and it is necessary to study and discover the causes of brown bricks, and strive to fire brown bricks in every kiln. ”

"Your Highness, rest assured, we will study it carefully and live up to Your Highness."

Wu Yuping hurriedly bent down to guarantee.

"In this way, this king will give you a chance, as long as you increase the productivity of this brown brick to fifty percent for me, and this king will restore the household registration of your five artisan households."

"Really...... It's true? Wu Yuping's voice trembled in surprise.

They can now be said to have no identity, and they belong to the one who could have been sentenced to death, and His Majesty opened the net to let them live in the northwest for the rest of their lives.

There is basically no hope left except to live.

Now Zhu Gaoxuan has given them a hope, and it is a bright hope.

"This king has always been a man of his word, and this is just the beginning, which of you is the best at burning lime, I will give you another task, the same household registration of five families as a reward."

Zhu Gaoxuan thought that with the bricks, he could start studying the cement, so he simply released a bait.

"Really...... Yes...... Yes. The villain knows that there are two people who are good at burning lime and are craftsmen at the level of craftsmen. ”

Wu Yuping still wanted to ask if it was true, and finally changed his mind.

"Get someone and come with me."

"Yes, the villain will go."

Wu Yuping trotted to find someone, and fell down several times because his steps were too fluttering.

It's so exciting.

Although the ten tasks of restoring household registration have not yet been completed, they are all tasks with experience to follow, and they can definitely be completed.

He was already running and fantasizing about what he would do after he regained his household registration.

"Your Highness, what to do with those unqualified bricks?"

Seeing that Zhu Gaoxuan had finished dealing with one thing, Zhu Anlan hurriedly asked.

"First pile on the side, the soil for making mud bricks has been dug to a certain depth, and those unqualified bricks will be pushed out and the land will be backfilled."

Zhu Anlan asked in surprise, "Ah...... Aren't those bricks meant to be used to pave the way? ”

"Did the king say he was going to pave the way? The king just wants you to lay a straight line out, which is used to place red bricks. ”

"Oh...... Yes, it's the lower officials who think too much. ”

Zhu Anlan's face turned red again, he made stupid several times today.

He bowed his head and stepped back to make arrangements.

The matter of the brick kiln workshop was basically decided, and Zhu Gaoxuan immediately led people to the lime workshop, and several people did not eat.

However, Xiaomei was more careful, and had already sent someone to bring a lot of dry food to the palace, and a group of people dealt with it casually and rushed to the lime workshop.

There is only one lime workshop in Lantian, which is also at the foot of Helan Mountain.

Helan Mountain is rich in limestone resources, it is easy to find suitable mines, and there are mountains and forests nearby, so it is easy to make all of them.

Quicklime and hydrated lime are two main building materials that have a long history of use in Chinese history, as early as the 7th century BC, that is, the Spring and Autumn Period and the Warring States Period.

Whether it is production or application, it is very mature, and there is no need to worry about Zhu Gaoxuan at all.

He's here for cement!

Seeing Zhu Gaoxuan arriving with more than a dozen people, foreman Bao Cang hurriedly greeted him.

"Greetings to Your Highness, welcome to all of you."

"Hmm...... During this time, do you have any clue about the cement I asked you to research? ”

Zhu Gaoxuan didn't talk nonsense and directly explained his intentions.

"Your Highness, I've taken a little chance, please come here."

Bao Cang naturally knew that His Royal Highness King Liang was coming, and he could only do one thing, that is, cement.

Then lead the way in front and walk behind the mountain forest on the right.
