Yuwen Rutong didn't understand why Zou Yu had to spend more money to let Xue Yantuo work. Of course, Zou Yu would not tell him that the dust of cement is too big, and it is easy to get tuberculosis after working for a long time.

"Just follow this requirement, and when the cement is fired in the future, everyone must cover their mouths and noses with a scarf." Zou Yu waved his hand and said.

"Whoa!" Yuwen Rutong saw that Zou Yu didn't want to explain, and he didn't ask, so he gave up.

Zou Yu also went to see the fired glass, and there were indeed fewer impurities and more pure ones; As for the porcelain, it was originally mostly blue and white, and the rest were some ugly variegated colors, and many times, there were more variegated colors than solid colors.

Now it is fired with refined coal, which has a more violent flame, and there are many kiln changes, which are very exquisite, with deep colors and overflowing streamers, like jade.

Even if Zou Yu doesn't know how to appreciate porcelain, he can't put it down when he holds these bowls and plates that look like jade.

"This batch of boutiques, pick them up, sell them to Guanzhong, and leave a part of them for Fengyulou as gifts." Zou Yu put down a dark plate in his hand and said.

Wind and rain building, listen to the wind and rain, this is not a secret in the Jinyang court, because their main role is to find out the news of other forces, and it is not internal.

As for the interior, Zou Yu plans to change the Yushitai in the future and change it into a simple regulatory department, legislation, law enforcement, and justice, which must be separated in order to avoid a single department, too much power, and to avoid the formation of the situation of the East and West Factory and Jinyiwei in the back.

After looking at the kiln, Zou Yu went to the coal mining area again, and the previous coal mine, when it was mined, would be transported away and transported to the place where it was needed. Now there is an additional process, which is coal washing.

A long slope was laid out of stone slabs, and the coal that had been knocked over was poured on it. At the top of the slope is a large pool, and the water pumped up by a waterwheel in sections washes down the slope and washes out the coal.

The water used to wash the coal is pumped up again by the water truck, and so it is recycled.

"It's good, it's just too troublesome, and the output can't be very high, after all, the location suitable for building a waterwheel is limited!" Looking at a coal washing pool composed of sixteen waterwheels, Zou Yu couldn't help but shake his head slightly.

"That's true, there is no way, if you mine too much, you can pile it up first and wait for the rain to wash away!

Instead of leading a canal, it is much more convenient to let the canal wash directly and then cut off the flow. Yuwen Rutong thought for a while and said.

"Never! Look at the water that has washed the coal mine! Black as ink! If it flows into the river, the whole river is finished! Not to mention the fish and shrimp in the water, the downstream people irrigate, and there will be problems with the draft.

When the harvest does not grow, and men and animals die of sickness, and a plague is brought to the side, you and I will be guilty of greatness. Zou Yu hurriedly stopped.

If you really follow Yuwen Rutong's suggestion, not to mention less, at least dozens of miles of rivers will be affected, the longer the time, the greater the scope of influence, for the sake of coal, turn a piece of land into a dead land, Zou Yu can't pass the hurdle of his conscience, especially this is his own territory.

"The prince is wise! It's not the prince's reminder that the Confucian boy almost became a sinner through the ages! Yuwen Rutong imagined the dark situation everywhere, and couldn't help but shiver all over, his face changed, he bowed to the end, and bowed cautiously.

"We are here to make people's lives better, so we must pay attention to the environment and not leave a disaster to future generations! It's not good to do bad things with good intentions! I encourage you to do this kind of thing. Zou Yu stepped forward to help Yuwen Rutong and said.

"Keep in mind the lower officials!" Yuwen Rutong nodded seriously.

"Craftsmen are one of the people who promote the development of society the fastest, and they can make things that shock the world, and they can benefit all people! It can also take people's lives. As the so-called ingenious workmanship, capable people can't, this is called a craftsman! Zou Yu pulled Yuwen Rutong and sighed.

"The lower officials must work hard to do what the prime minister said, and what capable people can't!" Yuwen Rutong didn't expect Zou Yu to take craftsmen so seriously, and suddenly had the mentality that a scholar would die as a confidant.

"It is not easy to make refined coal, so Jinyang supplies cement firing, Liaodong and Liaoxi, and gives priority to equipment workshops." Zou Yu admonished.

"Whoa!"

"By the way, how effective is the use of refined coal in steelmaking? Have you ever tried? Zou Yu asked with concern.

"I haven't had time to try it yet." Yuwen Rutong shook his head slightly.

"Give it a try! It just so happens that I don't have a weapon at hand. Go, go! Zou Yu's eyes lit up and he couldn't wait to say.

In the past, although there was a graphite dry pot and coal, the molten iron still had a lot of impurities, although it was much better than the previous standard equipment, but it was not a magic weapon. It has to be forged again. The biggest advantage is that it can be cast directly.

Although Jinyang has not found iron ore yet, it is still no problem to find some iron ingots, after all, Jinyang still has to forge things, so there is not a lot of inventory.

Back in Jinyang, it was not early, so Zou Yu let Yuwen Rutong go back and agreed to start early the next morning.

Today's iron-making and steel-making, under the leadership of the craftsman's supervisor, has undergone many improvements and has changed greatly.

Yan Lide, although Yan Liben is a brother, he has his own arrogance in terms of craftsmanship, and he is in charge of Jinyang and Liaodong, of course, he will secretly compete; Later, even if they admired the Yan Lide brothers, it was impossible for them to admit that their skills were inferior to others, especially in the areas they were good at.

Today you propose a revision, tomorrow I will find two solutions, now this steel-making furnace is no longer like before, open small furnace.

A closed furnace, one zhang five feet high, three zhang in circumference, all composed of graphite and clay, with an inner ring and an outer perimeter surrounded by green bricks. Two large bellows, being pulled by several bare-chested strong men, take turns.

As soon as he entered, Zou Yu felt a wave of heat, rushing towards his face, fortunately, he had studied forging for a while, and he was no stranger to this kind of thing.

"Last night, Xia Guan had people prepare, and it had been open for more than an hour." Yuwen Rutong introduced.

"I've seen the prince, Lang Zhong!" A stocky middle-aged man with muscular bumps on his arms stepped forward with excitement on his face to salute.

"Master Wang, how is it?" This is the craftsman in charge of forging, Zou Yu has seen it, and he is not polite, so he asked directly with concern.

"The firepower is much stronger, and the molten iron is about to come out!" Craftsman Wang said happily.

In the past, forging was to burn iron ore red, and then let ordinary laborers constantly calcine and beat it to make iron ingots; The ingots were then handed over to the apprentices who made the weapons, and they were repeatedly calcined and beaten again to make the embryos of the weapons; Finally, there are skilled craftsmen, forging and forming.
