Li Shimin's will: Li Zhi, the throne belongs to your brother

"The teacher ordered to use the stone bricks and cement, so the progress is very slow!"

Li Chunfeng looked distressed, carrying a large bag of materials.

Since it is from the School of Chemistry, Li Tai specially instructed to use stone bricks and cement, which are stronger and more resistant to explosions.

"It's okay, take your things to the ceramic kiln." Li Tai ordered.

After finishing speaking, he turned to Yan Wan and said, "Go, my husband will show you something good."

Under the puzzled eyes of the two, Li Tai led them to the ceramic kiln.

Chapter 73 Made of lead glass

"Put these into the kiln according to different proportions, and divide as many different proportions as possible."

Li Tai directed Li Chunfeng.

Quartz sand + soda ash + limestone can be refined into glass after high temperature.

But in practice, this will not be [-]% successful, because glass is amorphous and has no fixed melting point.

The melting point of quartz glass is 2500 degrees Celsius;

The melting point of soda-lime glass is 1600 degrees Celsius, and this type of glass is usually used as experimental glass.

Lead glass is below 1200 degrees Celsius. This type of glass is used to make lamps and drinking glasses...

Most of the ceramic kiln processing clay processing can only be processed to 1150-1200 degrees Celsius.

Therefore, the cellars in the Tang Dynasty rarely reached the temperature for refining glass.

The recipe has no lead added, and the kiln temperature is not enough, the chances of glass success are completely impossible.

To successfully refine glass, lead oxide must be added to the formula to refine lead glass, and at the same time, the fuel is changed to coal to increase the temperature of the pit.

As for the ratio of lead glass, Li Tai didn't know either.

Li Tai could only let Li Chunfeng do the rationing, weighing and recording.

A total of [-] lead glass recipes with different ratios were made, and each ratio was only a few tens of grams, about the size of a quail egg.

The container is made of stone bricks, a hole is dug in the stone bricks, the ingredients are put in, and the numbers are engraved on the bricks.

After this is successful, you will know the ratio.

All that needs to be done now is to light the furnace and wait.

The shortest wait is seven hours, and the longest can reach seven days.

This cellar is the Dragon Cellar, a long building, only about ten meters long, which looks like a chimney lying down. It heats up and cools down quickly, and can refine several tons of ceramics at a time.

Watching the cellar door being closed, everyone who had been busy for a long time breathed a sigh of relief.

"Husband? What is this burning sand for?"

Seeing that she was busy, Wu Meiniang stopped, holding back her stomach with questions, she couldn't help but asked Li Tai.

"They are sand now, but when they come out of the cellar, they will be valuable glass."

With a smile on his face, Li Tai slowly spoke to Wu Meiniang.

After Wu Meiniang listened, the corners of her eyes twitched, her face full of disbelief.

Seeing the disbelief on Wu Meiniang's face, Li Tai said indifferently.

"I know, Mei Niang doesn't believe it, and it will definitely surprise you when it's burnt out."

After finishing speaking, Li Tai changed the subject and asked back.

"If these things can be turned into colored glaze, is Mei Niang confident that the Chamber of Commerce will be established successfully?"

"This..." Wu Meiniang hesitated, frowning, thinking.

Li Tai didn't speak, just let Wu Meiniang think quietly.

"Use colored glaze as a lure to win over some of you and strengthen yourself.

And target those who disagree.

Going back and forth, he can drive them, just like driving the herd of horses. "

Li Tai's eyes widened after hearing this: "Very good."

The so-called emperor's mind can usually be summarized as wooing a group of people, dividing a group of people, and attacking a group of people.

In this way, a group of people are drawn together, and common interests are found here.Divide a group of people here to ensure their own status, and attack a group of people, thus finding a common goal.

With common interests and common goals, he is still in the dominant position. He is really a born politician.

Thinking of this, Li Tai couldn't help being startled, and didn't know whether it was good or bad to hand it over to him.

"My father agreed to the chamber of commerce, and sent Li Daozong to help.

Do it according to your method, whether it is to lure them for profit, or to act both hard and soft, as long as they can be smoothly included in the chamber of commerce. "

After Wu Meiniang heard this, her eyes widened, and her heart was agitated.

Li Shimin actually sent Li Daozong to help, which is obviously an idea of ​​the chamber of commerce!

Maybe I can really sit on the chairman of this chamber of commerce.

If it fails, at most the Wu family will be lost.

Compared with the benefits, this loss is nothing.

Li Tai looked at the ambitious Wu Meiniang and said, "Why, can this matter be settled?"

"As a concubine, His Highness will definitely look at you with admiration!" Wu Meiniang smiled like a flower.

"Wait and see!" Li Tai said to Wu Meiniang with a smile.

After several hours, Li Chunfeng came to report to Li Tai.

"Master, the colored glaze is already cold this time, and I am waiting for you to open the furnace, Master."

"Okay!" Li Tai got up quickly, pulled Wu Meiniang closer, and gave the order: "Open the furnace!"

Following Li Tai's order, the door of the Dragon Cellar was opened. Although it had been cold for a long time, it could still feel some temperature and heat.

A few workers walked in with normal expressions, apparently the temperature had reached the usual standard.

Everyone waited, and soon there were exclamations one after another in the cellar.

"What happened?"

"Did it get hit??"

The person in charge outside the door asked quickly.

"no···"

There were panic and bewildered voices from inside.

"Let them take out everything!!" Li Tai asked, frowning.

This group of people must have been frightened by the glass.

"Yes..." came the panicked voices of several workers.

Soon, several workers came out very slowly, staring closely at the stone brick model in their hands.

"Dawdling, why is walking slower than bastard!!"

Just as the manager was about to teach him a lesson, the worker showed the stone brick model to everyone with a look of panic and surprise.

I saw that the sand in the original pothole on the stone brick had been filled with a piece of green glass.

Everyone swallowed in unison, their eyes fixed on the green glass, and they began to think frantically about a problem in their minds.

"Why did you put sand in it and glass out of it??"

The atmosphere calmed down, and everyone dared not speak for a long time, racking their brains, they couldn't figure out what was going on.

Then Li Chunfeng shouted loudly, interrupting everyone's thinking: "Could it be that this is alchemy???"

"alchemy?"

"His Highness is using alchemy?"

"Nonsense, this is clearly Liuli, how is it alchemy?"

"Is that supposed to be practicing Liuli?"

"This is fairy art!"

千:;寻?小'说?:资:源,中;转'!裙,2"!0?6'?8?5".6:0!5:.8　　众人低声议论起来，将目光看向了李泰。

It's no wonder that when you go in, it's a pile of sand, and when you come out, it's still green colored glaze.

This is not a bit imaginative, this is magic...

Especially after Li Chunfeng yelled this voice.

Thinking of this, Li Tai was speechless, with countless complaints in his heart.

Practicing Liuli art... How did you become a fairy art?

What to look at, it is Li Chunfeng who is talking about...

It's a pity that the School of Chemistry has not been completed, otherwise the "Chemistry" textbook will be sent to you, and I will give you a class.

"What are you doing in a daze!? Haven't you taken them all out yet??"

Seeing that everyone was stunned, Li Tai didn't dare to move, so he quickly ordered.

"Yes... yes." The housekeeper ran away incoherently, and when he came back, he had an extra stick in his hand.

"Have you heard, why don't you hurry up and move out all the colored glazes!!"

"Yes..." After a commotion, several workers calmed down and began to move out carefully one by one, placing them in front of Li Tai.

Every time a piece was brought out, it caused a commotion, sometimes regretting the lack of glass, and sometimes marveling at the color of the glass.

Only Wu Meiniang and Li Chunfeng commented on the glass.

"Smooth and translucent, like water essence and mica essence."

"It's as bright as blue lakes and rivers, refreshing."

"Huanghuang is like the bright moon, noble and noble."

···

And the corners of Li Tai's mouth twitched like crystal... Isn't that just colorless glass?

Bihu?Is it the green piece? It may be more iron oxide.

Finally, the 100 yuan brick was placed in front of everyone.

One hundred formulas, the successful one is only 30 yuan, the color is different, and the colorless one is rarely.

There are more green and yellow, obviously it is a wrong decision to use green bricks as containers.

"The colors are different, just like the stars are shining...the brilliance is shining."

"Ahem!" Li Tai interrupted Wu Meiniang and Li Chunfeng's evaluation.

He said to Li Chunfeng, "Why don't you write down the number on it?"

"Yes." Li Chunfeng cheerfully picked up the pen and began to record the numbers on the stone bricks one by one.

"Husband...isn't he showing off his magic skills?" Wu Meiniang also looked at the glass, showing longing and love.

"No, it's just chemistry in science..." Li Tai said to Wu Meiniang speechlessly.

"Chemistry?" Wu Meiniang said involuntarily, her eyes bent into crescents.

"Chemistry is so beautiful~ I like chemistry"

Li Tai was speechless: "Cough... Mei Niang has a cup of tea, calm down."

Women like dragons like shiny things... Li Tai thinks that's right.

"Hmm~"

"Master, the disciples have memorized everything, please look over it, Master!"
