Wang Yisi nodded.

Zhu continued: "The responsibility of the Ministry of Industry is to fully coordinate all parties and make sure that the glass factory is put into construction in the fastest possible time. After all, this is different from the general factory, and the glass production is also very complicated. Go down and coordinate more. ”

Although the ministers still have doubts in their hearts, after all, this is in front of the emperor.

Asking too many questions is easy to reveal the shallowness of your knowledge.

So when they left the palace gate, everyone surrounded several researchers from the Royal Academy of Sciences.

"Oops.. The book "Industrial Manufacturing of Glass" that the emperor just said... Hehe, isn't it here at your Royal Academy of Sciences! ”

"It's just.... I can't just be taken back by you! I'm going to have to show it to all of us."

“！！！”

Several researchers from the Royal Academy of Sciences were shocked.

blurted out: "This, this, this.. This is what the emperor gave us to study the principle of production! ”

"That's because there's only one copy! The research on your production principle is only in the first step, but this time we are building at the same time, so it is also appropriate for everyone to see. Wang Yisi also interspersed with it and began to answer.

Purpose..

Everyone is the same, and that is to take back themselves.

After all, the earlier I read this book, the earlier I can have a deeper understanding of the industrially produced glass mentioned by Zhu Youzhen.

In case the emperor asks who it is.

At that point, if you don't know anything, you'll be in trouble.

In the end, the researchers of the Ming Royal Academy of Sciences, who had no way to take the ministers who were officials of the same dynasty around them, could only set their sights on the Huangming Newspaper before going back.

In the printing workshop used by the Huangming Newspaper to produce newspapers, fifty or sixty copies of "Industrial Glass Manufacturing" were printed in a few hours using movable type printing technology.

to this.

The crowd just began to disperse..

...

A few days later.

The various ministries that moved quickly concentrated their efforts on the first trial production, and the first of them was the glass kiln produced by the General Bureau of Ordnance.

Speaking of the manufacture of this glass kiln, it was originally impossible to find talents with the same experience in the General Bureau of Ordnance.

Later, I don't know who said it casually.

"This thing. . . Isn't it similar to the kiln where porcelain is fired? I don't know if I can find a few craftsmen who fire porcelain to try it out. ”

Afterwards.

After just a few attempts, a small glass kiln was born.

The whole was made of fine porcelain clay, which was able to withstand very high temperatures, and relying on the techniques learned in the book, a crucible was successfully produced in equal proportions.

In this way, the necessary conditions for production are basically solved.

So everyone began to gather in the Royal General Directorate of Ordnance, waiting for the first furnace of glass to come out, of course... The first furnace can only be an experiment.

And there is a high probability that it will fail, and everyone is ready for this.

The content of the book is actually extremely unfriendly to experimental production.

The first of these is the proportion of raw materials, you must know that the book introduces large-scale industrial production, and now it is the first production experiment in the Ming Dynasty.

Therefore, the researchers of the Royal Academy of Sciences also tried various methods to make calculations and adjustments.

But even so.

It is also necessary to observe the situation while producing.

The craftsmen of the General Bureau of Ordnance approached the hot glass kiln, took the crucible, and poured the raw materials that had been mixed in advance.

There are many portions of raw materials prepared, and there is a clear difference in the ratio between different portions.

As for the purpose, it is to be able to find out which formula can achieve the best results in the experimental production stage in this way.

Fortunately, with the collaborative support of multiple departments, a large number of materials can be found and deployed in the first time, otherwise the complex materials inside alone will be a headache.

What's more, it is necessary to disassemble the different operation methods of the whole process.

Otherwise, it is impossible for anyone to make a mistake in the first firing, and it is only possible to determine the different operating processes by performing multiple simulation tests.

Firing of glass.

The degree of craftsmanship is quite complex and the difficulty is also very high.

After the raw material is heated, saltpeter is added to the molten glass water to decolorize the original color.

This is because the raw materials of glass contain a lot of iron, which makes the glass show a green luster, especially it contains a lot of bivalent iron, which is why today's Ming Dynasty often fires glass into glass.

Modern industrial glass is different, after adding saltpeter, the divalent iron can be oxidized, making it colorless and transparent.

And after the glass firing is over.

There is also a clarification step by adding additives such as table salt to the glass hydrothermal solution to reduce the large number of air bubbles contained in the glass.

This minimizes air bubbles inside the glass.

Today's gathering here is not the top group of industrial talents in the Ming Dynasty, which has some overkill for the glass production process.

But no one thought that the production of glass would be a simple matter.

After all, for hundreds of years, no one has found that glass can actually be colorless, but now in the book "Industrial Manufacturing of Glass".

The glass described is as transparent as pure crystal.

Such a distinction makes these industrial talents of the Ming Dynasty obsessed.

Soon.

The first pot of glass solution was refined, and after all the steps were poured into a mold made of pig iron, which was made in imitation of the cast-iron cauldron.

Hiss.. The reddish glass solution cools gradually.

The mold is opened, and a transparent glass is made.

The transparent glass is padded with special gloves by the craftsman next to you, and you hold it in your hand to make sure that the temperature has dropped down completely, and then place it on a table next to you.

The glass, which exudes a luster like crystal, attracted the attention of the audience almost the moment it left the mold.

"Magical.. It's amazing, the old man has lived for so long, and he has never seen such a beautiful glass! ”

"It's still called Liuli? The emperor said that this is transparent glass! ”

"Beauty..."

As he spoke, Wang Yisi suddenly picked up the glass and kept looking at it, looking left and right.

"That's it?"

As soon as Wang Yisi spoke, another researcher from the Royal Academy of Sciences on the side shook his head and said, "It's almost."

As soon as these words came out, it was like pouring cold water on everyone...
