Chapter 612: Glass and Crystal

It's just that in many cases, women are forcibly becoming strong because of their own 'responsibility'!

It's not hard to see why.

To put it simply, it's like, everyone is a woman, everyone can do it, they are tough, they are active in everything, and men are passive.

When it comes to yourself, you can't let a man take the initiative, right?

That doesn't make people laugh out of their big teeth?

So, even if you're shy, embarrassed, or uncomfortable, you have to keep going!

Even for the sake of a woman's face, you must not be cowardly!

Under this mentality, women naturally look tough on the surface.

It's like crossing the previous earth, encountering robbers, even the most ordinary men, will bravely stand in front of women!

Of course, it is not excluded that there are a few soft eggs who will hide behind women, but there are very few such people.

This is almost the case with the empress, she is naturally unwilling to be passive, but in her heart, she may not really be as indifferent and tough as she seems......

At least, it's not so calm, and many times, it's gritting its teeth and 'acting', constantly cheering yourself up, so that you don't lose to other women......

It's a pity that Lin Zifan doesn't know this, he only knows that if he runs slowly, let alone be killed, it would be too crazy......

But I have been on the empress's round and perfect buttocks, and even almost kneaded the claws all night, I am afraid that I will not be able to keep it.

Even if it is saved, it will at least become a pair of pig's trotters, which is not easy to ......

......

After leaving Qifeng Pavilion, Lin Zifan did not go to the academy, and he did not even inform the academy that he had returned.

After all, in his imagination, the students' steam engines must not have been completed, at this time, what difference does it make to go or not?

On the contrary, more than half of the mission time in the city that never sleeps has passed, and it cannot be delayed any longer, and it needs to be completed as soon as possible.

Fortunately, copper and tungsten have been found, and rubber is ready-made, so there is no difficulty in making wires.

The tungsten filament used in incandescent lamps is slightly more difficult, because the tungsten filament has to be very thin, very thin, and it has to be like a spring, wrapped around many times, so as to ensure that it can emit enough light at that time.

As for the wattage or something, Lin Zifan can't control this thing 100%, so he can only get a 'big difference' to get it.

Nitrogen or something, you can also ask the national teacher to help you get it.

But beyond that, there's a problem.

That's ...... Glass!

This time, not only tungsten and copper, but also quartz sand, soda ash, limestone, feldspar and other raw materials needed to make glass, Lin Zifan also brought back some, at least in a short period of time.

And the location has been noted, even if it runs out, someone can be sent to retrieve it in time at that time.

But Lin Zifan is not particularly proficient in the technology of making glass, so he can only grope for it.

After all, his main job before crossing over was a chef, not an inventor, and he was not an expert in physics or chemistry.

"Fortunately, I had an understanding that the production of glass should be roughly divided into ...... Five steps?"

1. Pre-processing of raw materials.

The bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed to dry the wet raw materials, and the iron-containing raw materials are treated to remove iron to ensure the quality of the glass.

2. Preparation of batch.

3. Melting.

The glass batch is heated at a high temperature (1550~1600 degrees) in the pool kiln or crucible kiln to form a uniform, bubble-free liquid glass that meets the molding requirements.

4. Molding.

Liquid glass is processed into products of the desired shape, such as flat plates, various utensils, etc.

5. Heat treatment.

Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.

"But there are still problems......

"In this way, I believe that glass can be made, and if it is just used as window glass or something, there is no problem at all, but the problem is ...... How do you make thin and durable glass for light bulbs?"

"You can only test it first......"

He shook his head, shook his thoughts out, and began to prepare for how to make the first light bulb.

As for the wires, they can be handed over to the department to complete, and with the current 'scientific and technological level' of the department, there is nothing wrong with making the most ordinary wires.

Glass factory, in preparation.

But Lin Zifan can't wait for the glass factory to be completed, he has to make at least some samples before that!

After all, if the glass factory is completed and then started, it will be too late, and no one knows if it will be in time, and if the task cannot be completed on time, then it will not be the end of the calf?

Even if there is no mission failure penalty, but you can't get the task reward, isn't it equivalent to missing 800 million?

Fortunately, this is a high-martial world, and the high temperature is no longer a problem.

Even without a dedicated blast furnace, it can easily reach a high temperature of more than 1,500 degrees Celsius, completely melting the raw material of the glass and removing air bubbles.

In such a situation, it is not difficult to make glass, but it is difficult to make thin and uniform glass for light bulbs......

A few days later, the empress looked at the large and small glasses sent by the people from the department, and was a little curious.

"Aren't these crystals?"

"Back to Your Majesty, your lord said, this is glass. Li Goudan nodded again and again: "My lord also said that let his subordinates replace the window paper in His Majesty's bedroom with glass." ”

"In this way, His Majesty's bedroom will not be so deserted, and it will be much brighter. ”

Empress: "......"

Not crystals yet?

The empress was a little unconvinced, this thing that looked crystal clear and so uniform was even more valuable than crystal looking, right?

But when I thought of Lin Zifan, the first thing I thought of was to ask someone to send the glass to him, and I was very happy.

But this kind of happiness can't be shown......

"Hmmm......"

The empress drank the second pot head, as if she didn't care, and said, "You can change it." ”

After a busy half a day, finally, all the windows of Qifeng Pavilion were replaced with glass, which can be called a shotgun change, and the changes are amazing!

Although the window paper is also good, it looks a little older after all, and the light transmission is much worse than that of glass.

Therefore, even during the day, the inner room of Qifeng Pavilion needs to be lit with candles all year round to keep it bright.

But after replacing the glass, with the light transmittance of the glass, even the inner room can see normally, and the brightness is not low!

"It's so pretty......"

"yes, so many crystals, a lot of silver, right?"

"Lin Shangshu is really willing to spend money for the sake of His Majesty. ”

Tsing Yi and Ziyi looked at the greatly changed Qifeng Pavilion, their eyes were full of little stars, and they were envious.

But the empress drank the second pot head and pretended to be calm: "That's called glass!"
