Agriculture, industry and commerce are the class tone of this world. The craftsman is in the third place, and his status is one point worse than that of the farmer, but in fact the status of a good craftsman is not bad at all.

Especially because the so-called transmission of men to women, as well as the concept of teaching apprentices to starve to death of masters, make it extremely difficult to pass on the craft.

The mirror that Qin Ze wants to create needs to be not a casual craftsman. Ordinary copper mirrors, even if they are done to the extreme, are also impossible to be much clearer.

Because of the material of the copper mirror itself, it does not matter how smooth the surface of the craftsman can be polished. It can't change all the items it reflects, and they are all yellowed, so Qin Ze didn't consider the bronze mirror.

The mirrors of later generations were not made of brass, but of silver. Silver has excellent reflective properties and is also very malleable. So even if you make a mirror out of silver, it doesn't weigh much.

But in this era when it was still pure hand, it was extremely difficult to forge silver to the point where it was as thin as a cicada's wings. And because silver is easy to oxidize in the air, which will cause the reflective performance to plummet, it is necessary to ensure that the silver layer is isolated from the air.

Therefore, it is not feasible to use silver sheets alone, and the method in later generations is to plate the silver layer on the glass, so as to ensure that the silver layer will not be corroded.

And in this day and age, electroplating is no longer possible. Qin Ze didn't want to use the system to exchange either. Although this is the simplest, Qin Ze knows that doing this will only make Li Er believe in the existence of immortals even more.

And once an emperor begins to pursue this path, it is the beginning of the suffering of the people.

Therefore, Qin Ze needed a skilled craftsman who could beat the silver pieces extremely thin and fit perfectly on the glass. There must not be the slightest void in between, otherwise the air will slowly corrode the silver layer over time.

This is a very difficult matter, so Qin Ze must find Cheng Lao Demon.

In the past, the first emperor collected the world's iron tools to cast twelve gold people, and what he guarded against was that he was afraid that the people would have weapons in their hands. Although in the end, because of the corruption of the court, the Qin Dynasty collapsed. But it undoubtedly provided a precedent for later emperors, so there was the "Salt and Iron Order".

Even this is far from enough, in order to completely put an end to the rebellion of the people. The emperors came up with a new countermeasure, that is, to restrict craftsmen as well.

In this way, even if someone wants to rebel, even if he has a large amount of iron ore, but there is a lack of craftsmen to make weapons, it can only be a pile of scrap copper and rotten iron.

And the craftsman that Qin Ze needs must be a skilled blacksmith. It is impossible for this kind of craftsman to exist in an ordinary family, and it is only available in a noble family like Cheng Laoyou.

The craftsman's business was solved, but the glass had a problem. Although I know that this thing is made of ordinary sand with limestone and caustic soda, how to burn it is a problem.

Qin Ze felt that he didn't have the ability to make this thing, and it was impossible to make one temporarily, so he could only buy ready-made ones.

The glass was brought to the Tang Dynasty by Hu Shang, but now it is called colored glass, and it is all colored glass. Although it is not as transparent as colorless glass, it is enough.

It's just that the only problem is that this thing is extremely expensive, even to the point of sky-high prices, and ordinary people can't buy it at all. Even if Qin Ze wanted to buy one of these things, it was hard to find.

But Qin Ze remembered that there was a cyan transparent glass bowl in Cheng's mansion, which had been placed on the treasure shelf in the inner hall by Cheng Lao You, and it could be said that it was something he cherished extremely much.

The reason why Qin Ze knew this was that he had seen this thing on Cheng Lao Demon's treasure shelf once before. At that time, Qin Ze was still curious, how could someone put the broken glass bowl in such a conspicuous place. But when Qin Ze wanted to reach out and touch it, he was directly pushed away by Cheng Laoyou.

"This is a green silk glass bowl, it is a priceless thing, how dare you play with it at will?"

This is what Cheng Lao Demon said when he rejected Qin Ze at that time, and he still remembers Cheng Lao You's cautious look at that time.

If you want to create a silver mirror, glass is indispensable. Therefore, after waiting for Cheng Lao Demon to finish drinking the beef soup, Qin Ze said, "Uncle can you know the Zhongyuan Poetry Festival in five days?" ”

Cheng Lao Demon glanced at Qin Ze, and when he saw the smile on his face, he guessed most of it. At the moment, he also slapped the table and said: "If you have a fart, let it go, don't talk to a certain about these poor poems." ”

just likes Cheng Laoyou's free and easy appearance, and Qin Ze also said unceremoniously at the moment: "The Cui family has always been obsessed with the little nephew, and I heard that the old lady of the Cui family is still bedridden now. And the kid learned that the Cui family had colluded with the world's talents, and wanted to make things difficult for the kid on the Midyear Festival five days later. I also heard that this time they got a bronze mirror of ice spirit, and they planned to dedicate it to the queen.

The kid really didn't want the Cui family's treacherous plan to succeed, so he planned to create a silver mirror as well. It's just that now that the craftsman's matter has been solved, there is still a problem. ”

Speaking of this, Qin Ze looked at Cheng Huailiang on the side, who was still eating beef buns at this moment. I don't know if it was Cheng Laoyou who said that he could eat twenty buns when he was young stimulated Cheng Huailiang, anyway, he was eating more and more vigorously at this time. Even Qin Ze looked at him, but he didn't look up.

Cheng Lao Demon glanced at Cheng Huailiang with Qin Ze's gaze, and suddenly had an ominous premonition in his heart.

Sure enough, Qin Ze continued to speak: "The kid still needs the green silk glass bowl on the uncle's treasure shelf. ”

"No way!"

Cheng Lao Demon refused, and he didn't give Qin Ze any room to maneuver at all.

Qin Ze also continued unhurriedly: "In front of everyone that day, Brother Huailiang made a promise in person. As long as it is a treasure in the Cheng Mansion, you can choose it with the kid. Nowadays......"

"Poof~"

Before Qin Ze's words were finished, Cheng Huailiang on the side squirted out a mouthful of broth. There was also a look of astonishment on his face, and even the half-gnawed bun in his hand slipped out of his hand.

Cheng Huailiang probably didn't expect Qin Ze to ask for this thing, if it was an ordinary thing, he could still beg Cheng Lao Demon for a thing or two, but if it was this thing......

"When is this happening?" Cheng Lao Demon turned his head and stared at Cheng Huailiang with an extremely calm expression.

From childhood to adulthood, Cheng Huailiang was too familiar with this expression. And every time Cheng Lao Demon showed this expression, it meant that he was very angry now.

"Seriously." Although he was extremely apprehensive in his heart, Cheng Huailiang nodded firmly, and then looked at Qin Ze on the side.

Cheng Huailiang knows what kind of character he has, so he only hopes that Qin Ze can change his mind and let go of the green silk glass bowl.

It's a pity that only Qin Ze's extremely sympathetic eyes responded to him.

"My nephew called my uncle to dinner today, presumably just for this?" Cheng Lao Demon turned his head, but his face was already stacked with a smile with murderous intent.

Qin Ze calmly grabbed a bun from the cage on the side and handed it to Cheng Huailiang again. Then he filled Cheng Lao Demon with beef soup, and then said unhurriedly: "Uncle must not want to see the Cui family show off his might, and the little nephew is also worried about His Majesty." Uncle probably won't be unwilling, right? ”

"I just want to give you a good life now." Cheng Laoyou said that he was already ready to move.

Qin Ze had long known that this would be the result, so he stretched out his hand at the moment, compared his five fingers and said, "I will pay you back five in the future." ”

"Shall you take something that grows from a tree and falls from heaven? I can tell the green silk glass bowl, but a certain person bought it from Hu Shang for 800 yuan. Manchang'an is just one thing, and you want to give it to you now. Okay, let's talk to someone, what the hell are you going to do? ”

Cheng Lao Demon seemed to really like that thing, but since he let Qin Ze speak, it meant that this thing would definitely not be able to be saved.

The production of the silver mirror is very simple, and Qin Ze also said his plan without reservation. At the same time, he also repeatedly promised that he would return him five green silk glass bowls.

What Qin Ze said, Cheng Laoyou didn't seem to understand. After half a sound, a sentence popped up: "You say this thing is made of ordinary sand?" ”

"We also need to add caustic soda and limestone, but although the raw materials are simple, the process is very troublesome. So the kid couldn't make it for a while. Qin Ze replied fifteen-ten.

Cheng Laoyou listened. Scratching his head, he looked at Qin Ze, and then at the sand and dust on the ground. Then he frowned and said, "If you see it, how long will it take to make this thing?" ”

"Half a load at most, two months at least." In fact, if the conditions allowed, it would not take so long at all. It's just that this thing is too harsh on the temperature, which means that Qin Ze has to spend a lot of time making the refining furnace.

Cheng Lao Demon listened to Qin Ze's words, and he also fell into deep thought. After a long time, he made up his mind and said: "The green silk glass bowl can be delivered to you, but the matter of forging the glass must also participate." ”

Qin Ze shrugged indifferently, and he could be regarded as responding.

Although the words were simple, when Cheng Laoyou asked people to bring the green silk glass bowl. Still carefully wrapped several layers with silk.

In the end, Qin Ze was also impatient, so he directly snatched it over, and then threw it to Erhu casually.

Qin Ze's actions also made Cheng Laoyou's eyes widen, and he couldn't wait to rush up and take back the green silk glass bowl. But after all, I couldn't help but do nothing.

"What is the little nephew going to do with this?" Cheng Laoyou took one last look nostalgically and asked extremely unbearably.

"Find a furnace to melt first." Qin Ze said casually.

"Melt!"

Cheng Lao Demon on the other side jumped up all of a sudden. Pointing to the green silk glass bowl, he said: "This thing is the only thing in Chang'an, and it is worth a thousand gold, so you melted it?" ”

Qin Ze scratched his head, this thing was just a piece of broken glass in his opinion, and it was not as precious as Cheng Lao Demon thought at all.

Eight hundred guan was about to be melted by Qin Ze so casually, and everyone in the Hou Mansion who heard the news was also stunned.

"It's really the first loser in Chang'an!" It was a long time before someone spat out such a sentence.
