One time when she went to look for Sister Yun, she was not in the house, so her aunt asked her to wait in her sister's room.

She accidentally saw something shiny leaking out of the corner of the drawer. When she opened it out of curiosity, she saw a crystal clear object filled with royal blue pigment ground into powder, making the whole bottle shine.

Chang Sunxian had never seen anything like this.

It is purer, more transparent and harder than water, and you can clearly see the lines on your palms through it.

Out of curiosity, Chang Sunxian played with the bottle for a while and couldn't put it down.

She felt that this thing belonged to her sister and was a very precious item. It would be rude for her to take this thing out of the drawer, let alone ask her sister about the origin of this thing.

Perhaps from that time on, the Yun family became more and more mysterious in the heart of the eldest grandson.

"Your Majesty, this is how glass bowls are made. It's like colored glaze, fired at high temperatures." Yun Huachun said with great deception.

Glaze is very similar to glass, but it is far less pure and transparent than glass.

As early as the Bronze Age, there were craftsmen who pulled out colored glaze from the place where bronze was fired. However, glaze itself has a lot of colors, and most of the things that are fired are colorful, and there are also a few treasures in the homes of wealthy families.

But time is limited here, and pure and transparent colored glaze is almost impossible to see.

"If this thing can be produced, it will definitely become a pillar of the Jin Dynasty..." Yun Huachun said, feeling vaguely worried.

The glass is so novel. If the eldest grandson asks, how should he explain the origin of this recipe? Should he continue to say that it was a gift from God?

The eldest grandson smiled softly at Yun Huachun, bowed his hands slightly and saluted, "That's it, thank you for your hard work, sir."

Yun Huachun waved his hand hurriedly, "No hard work, no hard work!"

If one doesn't ask questions and the other doesn't want to explain, it's a good thing for both parties.

Arrangements for the glass factory were quickly made.

The prospecting is going very smoothly, and the rest of the coal is also available.

With the help of Yun Tao, Yun Huachun learned the art of making glass thoroughly, and then went into battle with the tools.

The documents in the space are undoubtedly very detailed and complete, but getting started is another matter.

In front of a high-temperature furnace with a red glow, Yun Huachun was wearing a coarse cloth gown with narrow sleeves and holding a long, thick black pole in his hands, the material of which could not be seen.

Different from the previous image of a fair and frail scholar, Yun Huachun's face seemed to be blackened by smoke, and large beads of sweat fell from his forehead from time to time.

There were also a bunch of people dressed similar to Yun Huachun standing around the house, some were busy adding coal, while others stood anxiously watching.

Yun Huachun puffed up his cheeks and blew for a long time before blowing out his first glass bottle.

The body of the bottle is irregular, with a larger bottom and a smaller top, and even the bottom is not flat. Yun Huachun was so excited when he blew glass for the first time, and many details were not handled well, which resulted in the glass bottle not being stable at all.

The purity of the glass is also not enough, and the overall color is grayish and yellowish.

Anyway, various problems made Yun Huachun himself not very satisfied.

But these are not problems, because he has taken the first step bravely!

A group of craftsmen and emperor's ministers gathered around Yun Huachun. They were very sensible and praised Yun Huachun and the bottle.

"Master Yun Hou is indeed extraordinary, being able to make such an ingenious treasure..."

"This treasure should have come from heaven and is hard to find on earth!"

"Thank you for your hard work, Lord Yun!"

Listening to everyone's voices, Yun Huachun rubbed his sore cheeks and had no strength to interrupt them for the time being.

He had to think about how to solve the subsequent problems.

Glassware is blown out, and flat glass is blown out.

When the first glass mirror came out, Yun Huachun planned to cut out half of it and send it to Changsun Xian to use it as a dressing mirror.

The best things in the world must first be attached to the emperor.

In addition, the four-dimensional glass bottle that Yun Huachun made for the first time was also sent over.

With a worried heart, Yun Huachun waited for half a day in the secret glass factory for the news from the palace.

The eunuch wearing pure red clothes announced the good news to Yun Huachun with a smile, "Master Yun, His Majesty said that the remaining mirror will be given to Princess Guangnan, and this bottle will be given to you."

"Your Majesty will remember your hard work and great achievements!"

With that said, the little eunuch on the side handed over two large sandalwood boxes.

Yun Huachun looked at the contents in the box, smiled and responded to the father-in-law beside him, and accepted the two boxes amidst everyone's envious looks.

I couldn't help but murmur in my heart, if I send these two things back, my wife and daughter will laugh at them.

Just as Yun Huachun thought, after Yun Huachun brought the things back, Yun Tao held the glass bottle and looked at it for a long time.

"Dad, I didn't expect you to be quite artistic!" Yuntao chuckled and praised.

Because the glass bottle cannot be placed vertically, the palace carpenter specially made a gold base to hold the bottle horizontally.

The transparent glass is placed on a pure gold base with carvings, which has a sense of wealth and wealth.

"Hey, if you blow it badly, how can you not be artistic?" Yun Huachun sighed.

Thinking of this, Yun Huachun thought of the craftsmen in the glass factory again, "Those craftsmen are really good. I can tell them roughly what I want to do and they can make it."

Yun Huachun was envious of this hands-on ability.

After saying that, Yun Huachun took another look at the glass bottle he blew himself. It was probably the ugliest thing among all the local glasses in Jin Dynasty.

"Dad, don't be discouraged. Our family doesn't make a living by making glass. It would be great if you can make it!" Yuntao praised, and then glanced at the glass bottle.

"This opening is quite big. It would be nice to put a candle in it and use it as a lampshade. It can prevent wind."

Thinking of the glass cover, Yuntao couldn't help but think of the kerosene lamp.

Yuntao thought of the kerosene lamps she had seen in the museum. The kerosene lamps were simple and crude in shape, and naturally the elegant Jin gentry would not like them.

"In the future, if you become more skilled in making glass and can make glass lampshades, you can consider kerosene lamps." Yuntao couldn't help but say.

Kerosene is sold to ordinary people to give them something to light up at night.

"It's possible, but these things will happen a long time ago, so we have to do it slowly." Yun Huachun sighed.

He also wanted everyone in the world to have access to lights, but the situation here was different from theirs, where they had eradicated feudalism and defeated the landlords.

There are too many big landowners here!

The main task of Glass now is to get money from aristocratic families to replenish the national treasury.

Some things are not yet suitable for popularization. Even if Yun Huachun hands over all the prescriptions, most of the people who benefit in the end will be high-ranking nobles.

The quality of life of the nobles will get better and better. For ordinary people, they will only become bricks and mortar in the luxurious life of the nobles.
