As he spoke, a young man from the workshop walked in with a piece of glass in both hands.

When opening and closing the door, Shao Yi had already seen the difference in glass through the reflection.

He didn't pay attention to the size, but the most important thing, the difference in smoothness.

The glass stood on a display shelf that could be placed diagonally, and the young man bowed and retreated.

Shao Yi walked to the display shelf, circled around the display shelf, looked at the glass carefully, swiped his fingers over it, and suddenly smiled.

Ah Can has the ability to pit people, but he really didn't say it.

This was the case with the previous glass jewelry, not only did I make a big profit, but I also fished out a huge amount of silver from a noble lady who didn't like it.

It won't take long for the glass jewelry of Baotai Yinlou to be sold at a diving price, but I am afraid that the lord of Shaohua and his ilk will vomit blood in anger.

This time, in order to find out the misbehaved employees, several wealthy families were deceived to build glass workshops.

However, once this kind of mirror-quality glass was launched, the glass made by these glass workshops was not only discarded, but only the glass was made and used in the heating shed.

It's just that the price, under the suppression of the price of the glass workshop, whether it can make a profit, it is difficult to say.

As long as he thought about that scene, Shao Yi felt funny.

If this kind of thing comes twice, I wonder if anyone will come to watch the craftsmanship of the glass workshop again? Is there anyone who can afford to make such a big investment not only unrewarded, but shameful?

He didn't care about the sales of this kind of glass now, nor did he care whether the emperor wanted to use the new products of the glass workshop first.

He just wanted to know, how did this glass, which has no ripples and is as smooth as a mirror, come to be? If she is plagiarized again, will she be able to make something better?

Shao Yi sat back in his chair and asked with a smile, "Miss Xia, I don't know if you can tell me, how did you blow out this glass?" ”

Xia Yanqing frowned when he heard this, there was no problem with the literal meaning of these words, but this blow was really not very good.

Xia Yanqing was helpless, so he had to say, "It's indeed blown out." The plasticity of molten glass is very good, not only can be assisted to blow out utensils of various shapes, but also can be assisted by traction to blow into a hollow glass cylinder. ”

Shao Yi's eyes lit up, as if he thought of something.

I only heard Xia Yanqing continue, "Cut the glass tube from the longitudinal length, reheat it, and when it has a tendency to soften, place it on a smooth plane and let it spread freely, which is this smooth mirror glass." Shao Gongzi also saw that blown glass is much better than the flatness and smoothness of pressed glass. ”

Shao Yi was stunned for a while, and then smiled, "Sure enough, as you said, as long as you can think of it, this skill is indeed not difficult." ”

The last time he and Xia Zitang went to the glass workshop, he saw with his own eyes that the molten glass showed unusual flexibility and malleability under the blowpipe of the craftsman.

During the blowing process, the molten glass can be easily transformed into the shape desired by the craftsman through assisted stretching or twisting.

And no matter what kind of blowing method or what shape it is made, the outer wall of the molten glass is absolutely smooth as a mirror.

But no one thought that the molten glass would be blown into a tube, and then cut and flattened.

He had been reminded by Xia Yanqing just now, and he used the blowing method, didn't he think of it?

And in Shao Yi's view, the speed and cost of this approach should be better than that of pressed glass.

"Miss Xia is really smart, as long as this mirror glass starts to be sold in the capital, I am afraid that it will be difficult to sell half a piece of glass on the market today." Shao Yi was sincerely admired.

Even if the three reduce the price, it is useless, and the people who buy the glass are all wealthy families. People are not afraid of spending money, they are afraid of being inferior and being ridiculed.

Xia Yanqing felt quite satisfied, "This is what I want, my family's craftsmanship, is it so easy to steal?" ”

Seeing that she was happy, Shao Yi was also sincerely happy, and asked with a smile, "If someone steals this skill, can you improve the quality of the glass again, so that the thief will lose all his money?" ”

Xia Yanqing glanced at him vigilantly, and did not answer, but only asked, "I don't know if Gongzi Shao has thought about it, how to replace the glass in the palace, can't the glass used by the rich and courtiers outside the imperial city be better than the emperor's?" ”

She didn't dare to guarantee that if she did, she would not be suspected of going against the grain.

As for someone stealing technology, she is not very worried, there is no bottom line in this world, but there are not many after all.

Human beings are active in groups, and they always have to take into account the eyes and opinions of the world when they act.

What's more, if you steal it once, you have already been pitted, who knows if you steal it again, will you be cheated again?

The advancement of glass technology is very difficult, and it has gone through hundreds of thousands of years.

Take flat glass as an example, as early as BC, glass production began to experiment with blowing methods. However, flat glass has always been made by pressing method.

It was not until more than 1,700 years later that this technique of making flat glass by the blowpipe method was developed, and the production of glass increased dramatically.

That's often the way things are, and sometimes, just a simple thought can make a big difference to the world.

However, this seemingly simple idea will only be stimulated by many opportunities and coincidences.

As a modern-day traveler, she is well versed in the evolution and evolution of glass technology, and even if it is stolen again, she can still introduce newer technology.

But others have to pay the price of real money and reputational damage to buy a lesson, not real technology.

Shao Yi saw that Xia Yanqing refused to tell him the truth, and he was a little lonely.

He said with little interest, "Of course, the best thing must be used by the emperor first, and you prepare the glass according to the original glass size and use it as a replacement." Now you can prepare some more large-size glass, as well as a glass knife, and also prepare two to facilitate the internal officials and supervisors to adjust the size of the glass according to the existing windows. ”

…………

The journey from the capital to Pingyang County was long, and in order to avoid the leakage of glass technology on the way, Xia Yanqing just sent all the existing mirror glass into the palace, and began to prepare for Mr. Bai and He Zhongzheng's trip south.
