"How can this be so close? Isn't this the transparent glass that the emperor said? A Ministry of Industry official retorted.

Unexpectedly, the researcher of the Royal Academy of Sciences took a few steps forward, took the transparent glass from Wang Yisi's hand, and explained to everyone.

"Although this glass has reached the full transparency that the emperor said, have you noticed that there are still a lot of bubbles and a lot of impurities in this glass."

"What's more important is that this glass is naturally transparent to the naked eye, but if I look at it.... When it is facing the sun, it is yellowing all over! ”

These words seemed to pull everyone from fantasy to reality.

But no one was discouraged, but said one after another.

"I was able to produce such a beautiful glass for the first time! I'm afraid that all the adults of the General Bureau of Ordnance have been bothering a lot lately.."

"yes.. Oh, yes! ”

..

After the glass was watched by the crowd, it was wrapped in bright yellow silk and taken away by a eunuch who was waiting not far away.

And everybody knew it.

The emperor is also waiting for the results of this experiment...

.. After the glass is sent into the palace.

Zhu Youzhen took it in his hand and looked at it carefully.

If you carefully observe with the naked eye, there are still a lot of bubbles and impurities in the glass, but despite this, such glass products can be successfully produced in Daming.

It is enough to see that all the officials of the Daming Department and the Bureau involved in the production have put a lot of effort into research, after all, what stays on paper is theory.

Only if you really eat it thoroughly, you can produce it.

to be able to call it technology.

After playing with it in his hand for a while, Zhu Youzhen put the glass down again, after all, the glass filled with a lot of bubbles is actually a fragile item in essence.

As the first serious industrial glass products of the Ming Dynasty.

It's still a bit commemorative, and Zhu Youzhen doesn't want to spoil it directly.

In addition, Zhu Youzhen suddenly thought of what kind of price such a glass would have to sell if it was sold in the private market.

I'm afraid it won't be cheap..

In fact, there was already colorless glass in this era, but it was not the Ming Dynasty that produced them, but in the glass workshop in Venice, Italy, far away in Europe.

This colorless glass is not only small, but also not very pure.

Not to mention such fragile goods, no merchant ship would be stupid enough to transport them across the sea, after all, such colorless glass is even in Italy.

It's also a rarity, which means it's already a very expensive luxury item in Europe.

But now, it's different.

Once Daming's glass has successfully entered the level of large-scale industrial production.

Declining production costs and the huge production of glass products are expected to make many people willing to reload this glass product from the East on merchant ships.

Drift across the ocean again and bring it back to Europe to sell.

And what about Da Ming?

Zhu Youzhen seemed to see the silver beckoning to him.

...

And in the courtyard of the General Directorate of Ordnance.

A large number of officials are still reluctant to leave here, after all, the final experiment is not completely over.

After all, they haven't gotten a "finished product" in the true sense of the word.

In order to make the glass more clear and transparent.

The crowd immediately decided to add a stirring process to the glass production process.

In other words, when using salt to remove air bubbles, use an iron rod to stir to release the air bubbles more fully.

Ultimately.

A finished glass that is almost completely transparent and devoid of any color was obtained.

At this point, it has basically been proved that the industrial production of glass products has absolute feasibility at the level of production technology, so large-scale construction and production can begin.

"In this way, the industrial production of this glass can begin to get on track, and there is one more thing you need to keep in mind." Finally, it was Xue Fengxiang from the Ministry of Industry who came forward to make the final summary.

Seeing that Xue Fengxiang, the secretary of the Ministry of Works, spoke in person, everyone hurriedly gathered around.

"The emperor said that glass production is related to the national economy and people's livelihood, and it is a confidential task of the imperial court, and everyone must remember that everything they see and hear today cannot be passed on..."

"If not."

Xue Fengxiang didn't say anything more, but everyone understood.

"It will be so... It will be so.."

...

At this time, Wang Yisi suddenly saw another person among the officials, and said loudly: "Lord Xie! Why are you here?!! Is there also a supply and marketing bureau for this glass production? ”

The words were full of surprise.

Xie Zihua, who heard this, knew that he was recognized, so he walked out of the crowd, grinned, and said, "Lord Wang is also here!" ”

"Why are you too.." Wang Yi didn't think about where the supply and marketing bureau could have anything to do with glass manufacturing.

I saw Xie Zihua greeting the surrounding officials one by one.

Then he said: "Where there is business, there should be Daming Supply and Marketing Bureau, and there should be me Xie Zihua!" ”

As soon as these words came out, the scene was silent, and everyone was a little speechless in their hearts.

The new director of the Daming Supply and Marketing Bureau seems to be more like a market vendor walking the streets and alleys, and his words are full of the smell of businessmen.

"Glass hasn't been produced yet? What about selling? Wang Yi was puzzled.

But Xie Zihua said: "Didn't the cloth of the State Administration of Industry also start to be sold? Business.. It's just talked. ”

.... However, after careful consideration.

Zhu Youjian finally gave the trade rights of the first batch of glass to the Daming Supply and Marketing Bureau, as another support for the supply and marketing bureau from the emperor and the imperial court.

However, Xie Zihua's appetite is far more than that.

One day a few days later, Xie Zihua's proposed recital was finally written, and someone was sent to the palace.

And in the East Warm Pavilion..

Zhu Youzhen couldn't calm down for a long time after seeing Xie Zihua's twists and turns!

He said directly: "Xie Zihua... It's exactly the same as what Xu Guangqi said... You can really give me a whole thing."

As for why Zhu Youzhen described Xie Zihua like this.

It is only because in the twists and turns presented by Xie Zihua, the omissions in the various trade measures of the Ming Dynasty are introduced in detail, that is, in foreign trade.

Da Ming has actually suffered a little all along.

Before and after the recital, he said a bunch of things, and Zhu Youzhen read out a sentence.

That's it.

"Your Majesty.. This errand, you will hand it over to me Xie Zihua and the Daming Supply and Marketing Bureau..."

Zhu Youzhen thought about it for a long time and didn't make up his mind, and decided to meet Xie Zihua of the Daming Supply and Marketing Bureau in person, after all, after Xu Guangqi's recommendation, Zhu Youzhen really had never seen this person.
