Hearing Old Man Hao say this, Su Hao couldn't help but blame himself first. Through the present, he has shaken out a lot of all kinds of modern knowledge in his mind, digging wells, repairing stoves, coal mining, burning glass, ......, it can be said that everything taken out makes the surrounding people feel amazing, but if you think about it carefully, it seems that there is really a lack of awareness of keeping business secrets.

Let's talk about this burning glass, using limestone instead of sheep's horn, using soda ash instead of saltpeter, and replacing the so-called glazed stone with quartz sand all over the mountain, which is a few key points to break through the bottleneck of glass production. Once this layer of window paper is pierced, it is easy for a skilled craftsman like Hao Yizong to make cheap glass.

Glass is currently not of much use in society, mainly because the price is unusually high and cannot compete with porcelain. Once the cost is reduced, coupled with the advantages of transparency, it is believed that it will soon become one of the most common materials in thousands of households like later generations. In such a big market, the profits in it are unimaginably large, and as the only one who has mastered the technical know-how, Su Hao did not hesitate at all, and showed the secret to Hao Yizong's family.

The reason for this is probably due to the habits that Su Hao brought from later generations, he has always worked in the geological department, and there are not many commercial cells in his head. In his opinion, none of these technologies were invented by himself, but should belong to the whole society. As for himself, there are so many opportunities to make money that he doesn't have to care about these at all.

Su Hao thought so, but in Hao Yizong's heart, it was a completely different idea. As a craftsman, he knows too well the value of technical know-how, how many craftsmen would rather be beheaded by the government than reveal the stunts left by their ancestors, the reason is that these stunts are the foundation of their entire family's survival, and if they are leaked, their children and grandchildren will be poor.

And this young master, who knows such a subtle glass formula, said it without reservation in front of Hao Qing, and personally instructed Hao Qing to burn a pot of high-grade glass, what kind of trust is this for his own family? If you don't tell you because you see this recipe, can it still be considered entry? Stealing from a teacher to learn the art is the most shameful behavior in the craftsman circle, if the technology is obtained in this way, the descendants will be said to be after the thief.

"Uncle Hao, this recipe for the little nephew is also hearsay, and it is not worth much. If Uncle Hao thinks it's useful, just use it. Su Hao said generously.

"How can that work?" Hao Yizong said, "If Master Su is willing to grant this skill to the old man, then Master Su is the old master, and the dog is the apprentice grandson of Master Su. ”

"No!" Su Hao flatly refused, "Uncle Hao, if you want to say this, then we have nothing to say." This recipe for burning glass, you can use it if you want to use it, and you don't want to use it to pull it down. ”

As soon as he said that, Hao Yizong's face immediately turned pale, and Hao Qing and Hao Tong also looked at each other, not knowing what was wrong. Su Hao said it so lightly before, but when Hao Yizong made a condition, he turned his face instead, where did this start? If it is suspected that the conditions given by Hao Yizong are too low, it seems that it is a little unreasonable, fifty percent of the profit, plus respecting each other with a teacher, what else does Su Hao want?

Su Hao walked up to Hao Yizong, took Hao Yizong's hand with both hands, and said, "Uncle Hao, you are more than enough to be my uncle at such an age, you say that I am your teacher, are you planning to break my life?" also said that Brother Hao is my apprentice grandson, and I am like a brother to Hao Tong, are you letting me be my grandfather?

This method of burning glass, I just got it by accident, I can enter the eyes of your Uncle Hao, get a compliment, the little nephew is very happy, where dare to take it out and sell it at a high price? The little nephew also said a few conditions here, if the uncle can agree, the little nephew will give this recipe away, and there are other formulas in the future, and I am willing to share them with my uncle. ”

Su Hao's words made Hao Yizong feel very emotional, he held Su Hao's hand and said: "Master Su is benevolent and righteous, and the old man is grateful." What does the master command, even if he listens to the old man, the old man does not dare to violate it in the slightest. ”

Su Hao said: "I am willing to give the formula of this glass to Brother Hao Qing as a gift for meeting." I want to ask Brother Hao to accept me as a brother, and I must not talk about any teacher and apprenticeship or anything like that. As for Uncle Hao, don't call me Master in the future, just ask me to change it, this is my cousin. In the future, Hao's workshop will make glass, no matter how much I get, I don't want anything, I just ask Brother Hao and Uncle Hao to help me make something often. ”

"This ......" Hao Yizong couldn't imagine that the conditions proposed by Su Hao were so simple, and such a good technology was given away in vain, and he actually just wanted to think that his father and son were uncles and eldest brothers, which could not be regarded as a condition at all.

He looked at Hao Tong with an inquiring gaze, and Hao Tong stepped forward and said, "Uncle, Master Su is a person with lofty ambitions, and he really can't look down on the glass formula. Since Master Su is willing to teach him, I think we can accept it. ”

Hao Yizong stomped his feet at this time, as if he had made up his mind, and said to Su Hao: "It's better to be respectful than to obey your fate, and change it...... Virtuous nephew, that old man accepted this generous gift with a cheeky face. What kind of glass devices will the virtuous nephew do in the future, no, not limited to the glaze, but all the devices that the old man can do, although the virtuous nephew speaks, the old man will definitely put down all the work in his hand and do it for the virtuous nephew. As for the income of this glaze, the virtuous nephew must take at least thirty percent, otherwise he will never make a piece of glaze again for the rest of his life. ”

If I don't agree to share in the workshop, this old man will swear never to make glass again, is this a threat to me? Su Hao thought with tears and laughter. He was willing to tell Hao Yizong the formula of the glass without reservation, mainly because he felt that the other party had actually mastered the manufacturing technology of glass, but there was something wrong in some places, and seeing the older generation of craftsmen trapped in the pit and unable to climb out, he instinctively wanted to reach out and pull it.

As for rejecting Hao Yizong's previous proposal to divide fifty-fifty, he also had the idea of retreating as advance. He believed that with the character of an old craftsman like Hao Yizong, he would never take advantage of his young income in vain, whether it was profit sharing, or helping himself to make something for free in the future, in short, he knew that he would definitely be able to get a reward from this matter.

Sure enough, Hao Yizong Jingran used such a method to force himself to take a thirty percent dividend, and if he refused, there was no need.

"Well, since Uncle Hao is so insistent, then the little nephew will be ashamed. Ancient into the clouds, the elders give, but disrespectful. However, the glazed stone used in this burning glaze must be provided by the little nephew, and the rest of the expenses and effort will be borne by Brother Hao, what do Uncle Hao and Brother Hao think? Su Hao said.

"It's so polite to change the virtuous brother." Hao Qingle said happily, hearing that his father had already changed his name to call Su Hao a virtuous nephew, he naturally followed suit.

The crowd said some polite words happily, Hao Yizong pointed to the dozens of colorless transparent glass that had just been made, and asked Su Hao: "Virtuous nephew, I heard Qing'er say that you want to polish these glass pieces into shape, I don't know what to grind them into, and what to use?" ”

Su Hao asked Xiao Wuzi to get a piece of paper, and picked up a charcoal strip from the pyre on the side, and then drew it for Hao Yizong on the paper, explaining while drawing:

"What my little nephew wants to do is some of these lenses. Each set is 4 pieces, two of which are convex and the size and shape are like this......"

Hao Yizong is an old craftsman, and as soon as he heard Su Hao, he knew what he wanted to make looked like, and he even figured out the specific polishing process in his mind. Hao Qing has been learning art with his father for many years, and his skills are quite good, listening to Su Hao talk about the situation, he also kept nodding his head, saying that he had understood, and he could do what Su Hao asked.

"After the convex mirror and the concave mirror are polished, please Uncle Hao put the convex mirror in front and the concave mirror in the back, and look at it from a distance. If the nephew is right, the uncle should be able to see clearly the scenery in the distance through these two lenses. Then, ask your uncle to fix the two lenses together with a cylinder to form a tube. A pair of lens barrels in one place allows both eyes to see together. In order to do this, the two pairs of lenses need to be ground to the same size so that the barrels on both sides are the same length. ”

Su Hao looked at the structure of the telescope of later generations and said to Hao Yizong. It's not realistic to make a reflecting telescope now, so let's make a pair of binoculars and use it.

"Can you see things in the distance clearly?" Hao Yizong really couldn't imagine what Su Hao wanted to explain.

Su Hao didn't explain, he believed that after Hao Yizong grinded out the lenses, and then aligned the convex mirror and the concave mirror back and forth, everything would be understood. Isn't the invention of the telescope the legendary because a mirror grinder stumbled upon this phenomenon?

"Don't worry, the old man will start grinding this lens now, and he will not delay the good nephew to come in handy." Hao Yizong didn't ask much, he directly agreed to Su Hao's request. As for wages and the like, needless to say, now everyone is a family.

Grinding lenses is a very troublesome thing, and it is naturally impossible for Su Hao to sit here and wait. After getting Hao Qing's promise to report as soon as it was completed, Su Hao took Hao Tong and Deng Kui into the second and left Hao's workshop.

Hao Qingdai's father sent the guests away, returned to the backyard, and asked his father: "Father, since Su Hao said that this recipe can be given to us for free, why do you have to share him with a thirty percent dividend?" In my son's opinion, we have earned money, and it is just a gift to him, and this thirty percent bonus will be passed on from generation to generation. ”

Hao Yizong said: "What do you know? This young man doesn't take such an expensive formula seriously, and he can send it in casually, but it can be seen that the good things in his stomach are far more than this glass formula. Let's give out a three-point bonus, and tie him to us, and in the future, he will come up with a little bit of skill casually, and how can we buy this three-point bonus? ”

"The father is far-sighted, and the son is blind-eyed." Hao Qing suddenly realized.

Hao Yizong said: "Go and bring the oil stone, let's do it together and grind out the things that Su Hao wants as soon as possible." Listen to what he said, this thing is also a valuable object, let's make it and see what is going on. ”
