At the end of the opening of the coke factory, Gao Pet took everyone to visit the nearest glass factory, and there were a few more tails behind than when they came, Su Huilan and Luo Hanbing's two younger brothers.

Fluorite has a wide range of uses as a slag making agent, and no one has found its use in the Southern Song Dynasty. It was not developed and applied until the 16th century in Western Europe. Adding fluorite in glass and cement manufacturing can reduce the melting point, reduce the requirements for kiln temperature, save costs, and is also a sunscreen for processing colored glass, and optical glass is indispensable for it. In steelmaking production, it is a slag making agent to increase the fluidity and desulfurization and phosphorus of slag. The industrial usage is very large. Nearby places are Chizhou, Qingyang, Ningguo, Langxi, Guangde, Wuyi in Zhejiang has a large reserve. Chizhou and Qingyang are very close to Tongling, and they are only thirty or forty miles away, so last time Gao Zhong asked his grandfather to find them. Fluorite often shows bright colors, transparent or translucent, and when placed in the sun, it will fluoresce in the dark and will also emit phosphorescence. In fact, the main ingredient of the night pearl is fluorite.

Recently, Gao Pet has been checking the progress of the factory and the quality of the project, especially the structural dimensions and materials of the high-quality kilns, and has paid great attention to them. This is also a habit of being a manager in a previous life. The main body of the glass factory is basically good, and some of the materials have been procured in place, just wait for the refractory bricks and crucibles to be in place before the furnace can be fired.

Favor these people to the factory gate. Seeing that there are some wheelbarrows pulling goods to the factory, these cars can pull eight or nine hundred pounds, and now it has become the main force of transportation, the shipyard does the unicycle project, separated from the shipyard, and set up a separate car factory, not only to do this wheelbarrow, but also to do two-wheeled carriages and carriages, and the two-wheeled carriages or four-wheeled carriages made by high pets are very comfortable. Even if the road is uneven, it is not very bumpy, that is the secret of the car factory. It's very simple to say, Gao Pet added a spring suspension, which is a shock-absorbing device, which is a modern person, and the ground is simple, but the carriage with shock-absorbing is still after the eighteenth century.

The goods shipped to the factory this time are fluorite. They listened to the delivery person and according to the instructions, the best fluorite was pulled to the glass factory, and the general tailings were pulled to the cement factory. Gao Pet nodded.

At the ore pile, Gao Zhong saw that the quality of this mine was indeed first-class, and there were a few pieces of young green and lake blue fluorite that were very beautiful, and he picked out these fluorites and prepared to let the big pillars be ground into beads.

At this time, everyone gathered around and saw these five and six colors of gem-like things, and they couldn't imagine that the glass was made of such beautiful raw materials.

"Have you ever seen the Night Pearl?" Everyone shook their heads.

"Have you heard of the Night Pearl?" Everyone nodded.

"The Night Pearl is a royal gem and is not allowed to be treasured by the people. So it's normal that you've heard of it and haven't seen it. ”

"If the Night Pearl is made of this kind of stone, you will definitely not believe it." Everyone's face was full of doubts.

"But that's the way it is." Perhaps only Gao Zhong is the only one in this world who knows this secret.

"Speaking of the Pearl of the Night, I'll tell you a story first." Hearing the story of Gao Pet, everyone gathered around.

Gao Pet told them the story of the Night Pearl, which really has the flavor of "One Thousand and One Nights".

"Once upon a time, there was a Great Qin State, and the king of the Great Qin Kingdom had three princes, and the king was old and wanted to pass the throne to the prince, but he loved these three sons and were all very capable, I don't know who to pass them on, and the king had a headache for this matter."

At this time, one of his prime ministers gave him an idea, and asked the three princes to go out to experience and test their hearts. Let each prince take a thousand taels of gold to do business, and whoever earns more money and has a good reputation in three years will pass the throne to whomever he wants. The king sent people behind his back to record the words and deeds of each prince. ”

"The eldest prince came, and he took a thousand taels of gold and returned home. This eldest prince thought, I am the eldest prince, being a prince is a certainty, when will the prince personally do this ninth-rate business? I called a few of my subordinates and asked them to get money, saying that if anyone gave more money, they would be the official of whoever I became king. I go to Qinglou and tavern every day to drink and fart. ”

"The king got it and shook his head"

The second prince also took a thousand taels of gold and left, he thought, what kind of business to make money, when he was having a headache, one of his subordinates came in and asked, why is the second prince troubled? The prince said, 'My father gave each of my three brothers a thousand taels of gold to do business, and whoever earns more money will make him prince and king,' and his men said, 'Prince, this is too simple, what business can make money better than making arms, and if you sell arms and let a few small countries fight, you will definitely make a fortune.' The second prince really used the power in his hands to make wars between his subjects, and he immediately made a lot of money in the arms business. ”

"When the king found out, he shook his head and said: 'If you forget to fight, you will die!' ”

The third prince also took a thousand taels of gold, and he thought: I once heard from the maritime merchants that there are many countries in the southwest of the sea, and there are many curiosities, such as persimmon trees like lanterns, and sweet potatoes with high yields, all of which can be imported into Daqin to solve Daqin's grain problem. The characters there like the porcelain, silk, and tea of Daqin, and I can sell my country's tea, porcelain, and silk to those countries, and I can also introduce their grain varieties, rare treasures, and increase my knowledge. So he exchanged all his money for tea, porcelain, and rented a big ship to go overseas. When he arrived in a foreign country, he quickly exchanged all the goods he had brought with him for exotic curiosities, seeds, and jewelry. drove the boat and walked towards Daqin. ”

"But when he arrived in the East China Sea, unfortunately, he encountered a typhoon, and the wind was very strong, and all the sailors on the ship died, and only the prince died so faint that he was on the ship, and the ship was spinning in the sea line."

"Cousin, has the prince been saved?" Su Huilan asked curiously.

"Besides, there is an aquarium in this sea, people call her the mermaid tribe, and the people of this mermaid tribe are very kind, they have a good voice, they sing very beautifully, and when they are fine, they like to sit on the reef and sing."

"There is a princess in this mermaid clan, and her name is Nasha."

"On this day, she went to the Dragon Palace of the East China Sea to play, where the princess of the Dragon Palace was her good friend."

"On her way home from the Dragon Palace that day, she saw a boat on the way and circled there. There were a lot of planks floating on the side. The mermaid is very kind, she knows that it is an accident boat and wants to see if anyone is still alive on board. She wanted to help them. In fact, this is the ship of the third prince. The third prince had been in a coma on the ship for three days. Nasha sailed the boat to the nearest island and brought the third prince back to life. The third prince is very handsome, Nasha is beautiful, they fell in love at first sight, they wanted to fall in love, and soon they lived together, Nasha was a kind wife, and when the prince was unhappy, he sang to him. When Nasha felt lonely, the prince told her about Daqin, and they were very happy and happy. ”

As the days passed, the prince became more and more silent, and gradually lost his smiling face, and Nasha knew that the prince was homesick, thinking of his father, his mother, and his brothers and subjects. How can a man be in the gentle country forever, a man must have a career! One day, when Nasha knew that a convoy of merchant ships was passing through here, she stopped them and gave them a lot of pearls, and asked them to help the prince repair the ship and send the prince home, and the merchants agreed to help her repair the ship. When he was leaving, the prince wanted to take Nasha with him, but Nasha knew that it was impossible, she was not a human race, she had no feet, and she could not leave the water for too long, so the two cried and parted. The prince promised her that he would come back to see her. ”

"Did the prince go back later?" asked Han Bing.

"It was exactly three years when the prince returned to the palace. But there has been no news of the third prince for three years, and the king is sick because he misses the third prince. Seeing the seeds and treasures brought back by the prince, the king made the third prince the crown prince. A year later the king died, and the third prince became king. After becoming the king, the third prince was even busier, and because he was busy, he forgot about Nasha. ”

"After the third prince left, Nasha was very sad, and she sat on the reef every day and cried and sang sad songs. Tears fell on the stones beneath her feet, and three years later Nasha died of grief. Before he died, he kept calling the name of the third prince, and blood flowed from his eyes. ”

At this point, several girls cried, "Nasha is so pathetic! ”

"Besides, there is a fishing village on the edge of the East China Sea, called Zhangjiagang, and most of the people in this port village are Zhang. There is an old man in the village who is over 60 years old, has no children or daughters, and his wife died a few years ago. On this day, he went fishing, encountered a storm and waves, got lost, and did not find his way home until dark. The old man was tired and hungry, and even worse he had no water to drink for almost a day, and he was thirsty. You know that this sea is salty and cannot be drunk. But when she was cornered, he heard the singing, but it was sad. ”

Uncle Zhang followed the song, and there was a lamp that was on, emitting a very soft pale green light. Uncle Zhang thought that he had reached the shore, so he quickly rowed away, and when he saw it, he realized that it was a small island. It was a stone that shone brightly. When it was dawn, I realized that it was a light green bead. There is a fist size. This bead was actually changed from Nasha's tears. The next day, Zhang Bo rowed to the north. Soon arrived at Zhangjiagang. At night, Uncle Zhang knew that he had a pearl, which must be a treasure, and he didn't know what to do. I fell asleep when I watched it. ”

"There is a lazy second-rate man in Zhangjiagang, named Zhao Si, who passed in front of Uncle Zhang's house that night. Seeing a green light from Uncle Zhang's house, there was also a very sad singing voice from the girl. He was very curious, and when he lay on the customer, he saw a bead on the table that emitted a very beautiful soft green light, and he knew that it was a treasure, so he ran away when he entered the house and stole it. ”

He didn't dare to run to the village for fear of being seen, so he ran to the city, but in the middle of the night he was in a panic, and the night watchmen saw that he was very suspicious, so they arrested him, searched his body, found beads, and asked him where he came from, but he couldn't tell him, and he was put in prison. The lord in the palace did not dare to keep the beads, so he gave them to the king. The king was pleased, and promoted him to prefect. ”

The king, as he liked it, brought the beads back to his chamber. He fell asleep with the beads in his arms, and in his dream he seemed to hear a familiar voice, which was the song that Nasha had sung to him, and he remembered that he had promised to see Nasha, and suddenly he woke up and saw a beautiful woman sitting in front of the bed, it was his wife Nasha. When husband and wife get together, they hug their heads and cry. From then on, Nasha returned to the beads in the morning, and in the evening Nasha came out to meet the king. Later, the king ordered that the people who got the night pearl must be handed over to the royal family, and they must not be kept privately, otherwise they will destroy the three clans. ”

"That's where the Pearl of the Night comes from."

"Young Master, didn't you say that the Night Pearl was born in the sea?"

"It's a bit complicated, a long, long time ago, we used to have the sea here, and then it became land, isn't there such a thing as the vicissitudes of the sea, that's it, don't you also see that there are shells in many stones, this is the evidence."

"I see, are these really glow-in-the-dark stones?"

"If you don't want to believe that this stone is luminous, each of you will pick a few stones that you think are the most beautiful, and come with me."

Gao Pet led them to the new furnace, which was very dark.

"What do you see?"

"The stone in my hand is lit" "Mine too"

"This is the luminous stone, and the beads made into the luminous pearl are the luminous pearls, also called the night pearl."

"This is the secret of the Pearl of the Night! Don't tell anyone about this secret. ”

"Haha, I also have a night pearl," Lao Shi shouted. Gao Pet saw that the fluorite in Han Bing's hand was particularly bright and had string light, and this little girl's luck was really good. This is a noctilucent stone.

"Han Bing, bring me your glow-in-the-dark stone." Everyone looked at the ice together. The fluorite on Ice's hand emits a bright green (emerald color). This is the cold ice, these fluorites are particularly rich in rare earth elements.

"This is a real high quality luminous stone. You go outside and look like you, and everyone helps her. We've really found the treasure. "This mine is likely to be a high-grade fluorite mine, and then we will have to arrange for beneficiation first, which is an opportunity to make a lot of money.

The gang later selected more than twenty emerald luminous stones the size of eggs from this pile of ore, and eighteen cloud-white luminous stones in the form of rotten clouds. Everyone is happy. Grinding into pearls, that is priceless. Not to mention the set.

"I'm going to cut these glow-in-the-dark stones, two for each of them, and there's just nine left-for-cold for the cold ice. The other eighteen clouds and misty white took a penny for everyone when the time came, and you can go and find a smaller one or make a chain. Find the person who belongs to it. But there is one thing, don't let people know about this, especially the official family, it is a capital crime to hide the night pearl privately. ”

"I know" the word "everyone", but no matter what, it still can't hide the happiness in my heart.

Gao Zhong arranged for Dazhu to investigate the situation of these glowstone mines, and asked the family to make other arrangements to control the mining of these glowstone mines, and all high-grade glowstones should be picked out and polished into jewelry. For those with string light, they will be treasured at home and processed according to the situation.
