Chapter 272: It turned out to be a transparent, smooth and hard substance.
In the design of the kiln, Ruan Mian specially made a semi-downdraft kiln, which can make fuller use of heat, and the temperature of the air combustion is sufficient to smelt quartz sand.
The calcined quartz sand is poured directly into snow water and cooled quickly to remove impurities and obtain purer silicon dioxide.
During the second calcination, limestone and silicon dioxide are mixed in a certain proportion and put into the kiln to be smelted into glass.
At first, many people found it novel. They had never heard of this glass before.
As for what it looks like after smelting, no one has ever seen it.
It was not until the first finished product came out that everyone saw that it was a transparent, smooth and hard substance.
It felt like the inside of a shell on the seashore. Even the knowledgeable old man and Zhang Yue were all shocked as they gathered around the glass.
"This looks like some kind of crystalline mineral, but the minerals I've seen before aren't this clear, nor are they this flat."
Ruan Mian smiled softly: "This glass liquid can be made into various shapes before it cools and solidifies, but this is the one we need most right now."
"The purity of this material is still not perfect. I will make further adjustments in the future and it will definitely be more translucent. But this is enough to be used as the heat-collecting wall of our sun room."
The old man stroked his beard and finally understood the principle behind Ruan Mian's sunroom construction.
"This glass is light-transmitting and wind-proof. Once it's built into a small house, the soil inside won't freeze, and the temperature inside can even rise when the sun shines."
"Madam Ruan also had fire channels dug under the soil to generate heat. As we all know, spreading a layer of horse manure on the soil also has a heat-insulating effect. This place, inside and out, provides sufficient growing conditions for crops. No wonder Madam Ruan said she can grow them!"
With this achievement, everyone worked harder in the future.
However, the news could not be kept secret in the village. After a few days, it was somehow spread to Wuheng City.
That day, Ruan Mian was still in the weaving workshop, chatting and laughing with the women, but unexpectedly Cuizhu came over in a hurry, speaking breathlessly.
"Girl! A... a seventh-rank official! He actually wants to smash our kiln!" As soon as these words came out, everyone present stood up.
Ruan Mian frowned, but remained calm: "A seventh-rank official?"
"It is said that he was a former subordinate of Chen Bozong. Now that Master Chen is gone, the court has not yet sent an official, and General Huo is away guarding the border, so the affairs of the city have been temporarily handed over to that humble official."
"But this petty official heard from somewhere that we were clearing the mountain without his permission, and he's now starting a fight with us at the kiln!"
Unauthorized excavation of the mountain to open up wasteland? Could this be a reason to find fault?
Ruan Mian smiled and calmly went to the kiln with Cuizhu.
When they got there, they found that the kiln workers were almost fighting with the police, but they were stopped by Yun Xiu.
Yun Xiu knew very well that the other party was a government official, and if they clashed with him, it would only bring bad things to the villagers.
He always remembered what the adults had told him: to stay calm and not act rashly.
Everything is in our hands, and there is an explanation for it.
When you can't figure it out, consider using force as the next step.
But although this minor official was of the seventh rank, he was also in charge of things in Wuheng City, especially since General Huo was not there.
Someone else reminded him, "Sir, we are helping the Ruan family. The eldest daughter of the Ruan family is the future general's wife. You should at least consider the Buddha's favor, right? We..."
"General's wife? Humph!"
The official stroked his goatee, his face full of disdain: "It's been so long since we've been engaged, and the marriage hasn't happened yet. How can this marriage ever be successful?"
"I think General Huo has lost interest in getting married, so stop using these things to pressure me! I'm the Wu Heng manager now, and you've been mining without permission, and you've gone to so much trouble to build something unpresentable here! If I don't tear this all down today and return the land to farmland, I'll lose my job!"
"Someone come! Tear it down!"
As soon as he finished speaking, a dagger flew from the air! With lightning speed, it pierced the official's black hat and nailed it to the tree trunk beside him with a "dong" sound.
Everyone was frightened and froze in place. Before they could react, a figure rushed in front of the official and grabbed his neck tightly with slender fingers.
It instantly snatched away his breath, frightening the official so much that his face turned pale. He struggled and shouted, "How dare you! How dare you kill... kill me?!"
His expression was distorted, and the officers behind him raised their swords.
Ruan Mian, who had just arrived, was also shocked. The one who wanted to strangle the official to death was the expressionless Mei Xi.
Her skills just now really surprised Ruan Mian.
Unknowingly, her skills had reached a superb level. Ruan Mian usually didn't pay much attention to this aspect.
Now it seems that he is worthy of being the killer trained by the five princesses in the original book.
Even if she doesn't have professional training, she can still reach this level by relying on her own understanding and practice. She must be quite capable.
But given the current situation, Ruan Mian quickly spoke out.
"Xixi, let's be polite too."
When everyone saw Ruan Mian coming, they all looked over, and Mei Xi's hands loosened a little.
The seventh-rank official took this opportunity to shout, "Ruan! Even though you have been admitted to the good family, you cannot commit crimes against your superiors! With so many people watching today, how dare you touch me?!"
Ruan Mian smiled slightly, looked at the officers slowly and calmly.
"Sir, your men total no more than twelve. Do you know how many people there are in our entire village?"
"You forcibly demolished our kiln and blocked our way to survival. You both want us dead. Since you won't give us a way to survive, why should we give you a way to survive?"
After saying this, he handed Xixi another dagger from his sleeve and said, "Since the official doesn't want us to live, then we can only give him a taste of his own medicine."
"Don't worry, sir. I will definitely not leave a single bone for outsiders to find."
Ruan Mian's slow and unhurried voice sounded like the King of Hell locking up souls. Not only did the small official tremble after hearing it, but even the officers next to him looked at each other in disbelief.
But their village is large and powerful, and the workers in the kiln are big and strong, with a ferocious and scary aura!
The seventh-rank official immediately became intimidated and shouted loudly, "Nguyen and Nguyen! How can you be so unreasonable? What's wrong with me following the law?!"
"Laws? Besides gold and iron mines, there's nothing in this dynasty that forbids private mining of stone mines, right? Besides, we mine to grow crops and provide for the people's livelihoods. What's wrong with that?"
"Growing crops?! It's so cold, the winter crops have all frozen to death, and you still want to use this excuse to trick me?"
