God-level Consort of the Tang Dynasty

Chapter 873 Heart-Shaped Glass
Yuan Qingfeng, Lu Hao and others hurried forward to salute.

"Meet Master!"

"Master, have you eaten yet?"

Duho was frustrated.

Just these two disciples, they even have different greeting styles.

What a worthless thing!
You can't even learn the traditions of the teacher's school!
Du He walked quickly to the table.

Li Ke said excitedly: "Teacher, look at this glass, it's so big!"

Yuan Qingfeng said: "Teacher, look at this colored glaze, it's so white!"

Lu Hao said: "Teacher, look at this glass, it's really good!"

Du He: "..."

Mo Yifei stood aside, staring at Du He with radiant eyes, as if a primary school student was waiting to be praised after cleaning the toilet.

He glanced at the glass, and said lightly: "There are too many impurities, there are problems with the raw materials, the ratio is wrong, the temperature of the calcination is not enough, the surface is uneven and has pits, there are small cracks on the edges, and the cooling method is wrong. Irregular shape, no standard moulds...this is a test case, useless!"

What?
Li Ke and the others all stared wide-eyed.

Such a perfect piece of colored glaze is worthless in the eyes of the teacher.

How did they know that the so-called glass in front of them was not even comparable to the glass windows of the old house where Du He lived when he was a child.

As for Mo Yifei, his eyes dimmed, and his eyes were filled with tears, which were about to fall.

Suddenly, I heard Du He say: "However, it is already remarkable to be able to make it, and it can be improved... You all go, Miss Mo, you stay, and show me your experimental records. There is room for improvement!"

Mo Yifei raised her head when she heard the words, her hands trembling with excitement: "Really...really?"

"Of course!"

"Great!"

Mo Yifei hurriedly searched for his experiment records.

But Yuan Tiangang and others left the courtyard.

Walking outside, Lu Hao asked curiously: "Teacher wants to improve the method of making colored glaze with Miss Mo? Why don't you let us watch?"

Li Ke said angrily: "You know what a fart, think about it, this colored glaze is calcined, and the stove is in the yard, and it feels extremely hot from a long distance away. If Miss Mo and the teacher re-fired colored glaze , what if it gets hot?"

Lu Hao blurted out without hesitation: "Of course it's undressing!"

"That's right," Li Ke looked like someone who came here, "Lonely men and widows, take off your clothes, what can you do?"

Lu Hao shook his head: "I don't know..."

Li Ke said speechlessly: "You really know shit, forget it, you don't understand even if I tell you, you don't understand the joy of getting along with men and women..."

As he said that, the guy laughed shamelessly.

……

yard.

Du He read Mo Yifei's experiment records intently.

He discovered the raw material problem in Mo Yifei's records.

After countless experiments, Mo Yifei determined that the raw materials for firing colored glaze are: quartz sand, limestone, and feldspar.

These are very common mineral raw materials, which can be collected around Chang'an, and the R&D center has a large amount of storage.

Du He put down the notebook and said, "One of the problems I mentioned just now is the problem of proportioning. To obtain pure colored glaze, one more raw material must be added!"

"What kind of raw material is it?" Mo Yifei asked, and hurriedly picked up the notebook and pen, ready to record.

Du He rested his chin on his right hand and said, "Why don't you try adding soda stone!"

The so-called soda stone is a kind of snow-white stone in the provincial capital of the salt mine. It looks similar to salt, but it is not salt. It tastes extremely bitter and highly poisonous. It may even kill you.

Afterwards, Du He and Mo Yifei started to get busy.

The first step is the ingredients.

This step of work is actually simple. With Mo Yifei's experimental records, Du He basically operates according to the ratio of raw materials.

Du He turned against the hostess, while Mo Yifei became the attacker.

For some reason, once Mo Yifei got close to Du He, she felt her heart beating non-stop, and her usually sharp hands became uncontrollable at this moment.

She even didn't dare to look into Du He's eyes.

The second step is melting.

The raw materials are packed in special earthen jars and put into the stove.

Add coal to the bottom of the furnace, light it up, and Mo Yifei and Du He take turns to step on the foot-operated blower to make the coal in the furnace burn fully and reach the melting temperature.

Around the stove, the temperature is getting higher and higher.

Du He was already dripping with sweat.

And because Mo Yifei was wearing thin clothes, at this moment, his clothes were all wet with sweat, and his figure could be seen at a glance. Du He feasted his eyes.

The third step is shaping.

This is a critical step.

Du He took a palm-sized mold made of Uzi steel that had been prepared, put it on an iron shelf near the furnace, and quickly took out the clay pot that had been burnt to a liquid state to remove impurities floating on the surface. Then pour into molds, continue to remove impurities, and then let it cool slowly.

Four or five hours passed.

A piece of glass takes shape.

Du He carefully took away the mold, and a flawless palm-sized glass was displayed in front of Mo Yifei.

The glass is heart-shaped and two inches thick.

There are some small bubbles and impurities in it, but compared to Mo Yifei's previous works, it is more than a hundred times better.

Du He wiped the sweat from his forehead, glanced at Mo Yifei's chest, and said with emotion: "It's not easy!"

He suddenly felt a little parched.

Mo Yifei said excitedly: "Young Master Du, we succeeded!"

She held up the piece of colored glaze, looked at it carefully, and showed a happy smile, like a child.

After a long while, she suddenly looked at the heart-hearted Liuli reluctantly, and asked, "Can you give this to me?"

Du He nodded: "Since you like it, it is yours! But Miss Mo, there is something I want to discuss with you!"

Mo Yifei carefully held the glass in his hand, "Mr. Du, please tell me!"

Du He then said: "I want to set up a Datang Academy of Sciences, with you as the dean, to study such things in the future...Of course, the most important task is to step up research according to the method we just tried. In the fastest time, build an assembly line and start building glass!"

"Glass, you said this thing is called glass? Isn't it colored glaze?" Mo Yifei asked curiously.

Du He said with a smile: "In the past, this thing was called glass, but from today, it's called glass!"

Glass?

Mo Yifei was stunned.

But since it was Du He's name, she would definitely not object.

Datang Academy of Sciences was established in this way.

Du He took Mo Yifei and taught him how to do research.

Mo Yifei gathered more than a dozen experienced craftsmen and began to study the mass production of glass day and night.

This kind of small-scale production can definitely make Du He a fortune.

But Du He's goal is more than that.
