Glass is very versatile, especially clear glass. Of course, the main use in this day and age is windows. Transparent glass can make a room brighter than window paper. In fact, for hundreds of years, the Chinese people have been doing everything possible to improve the light transmittance of the window, in addition to the use of paper paste windows, the Song Dynasty appeared semi-transparent light tile, the material is either flake mica ore, or polished by shells, inlaid on the pane. After the Ming Dynasty, there were Ming tiles made of sheep's horns boiled into liquid, and the Ming tile corridor in Nanjing was famous for its specialized Ming tiles.

As for the glass...... At least until the introduction of clear glass in the West, no one ever thought of fitting it to a window. Perhaps, because it's a little too expensive.

It's really not cheap.

It's not because the raw materials for making glaze in the capital come from Boshan, but because of the backward level of technology, such as the unreasonable structure of the cellar furnace for melting glass, the low temperature and high fuel consumption.

However, in addition, there are also complete tools for processing glass, such as blowpipes and steel shears, and there are also about 20 craftsmen and apprentices. When watching Jiang Fangzhong try to make a tablet in the workshop, he only needs to look at his practice, and Shi Yiwen almost knows the answer, but even so, he still watched with great interest as he made various attempts there.

It took almost an hour, and after another failure, Jiang Fangzhong said with a flushed face.

"Hey, Gong, Gongzi, I'm not good at it, I make you laugh, I laugh......"

This will make his mood very low, he has always been dissatisfied with the status quo, but the reality that his skills are not as good as others, but he can only reluctantly accept the reality. Now I have found a new business opportunity after being mentioned, but I never thought that I would not be able to make it.

No wonder no one has tried this for so many years.

"It's not that you're not skilled, it's that you don't know what to do."

Smiling at Jiang Fangzhong, Shi Yiwen dropped another sentence.

"If you want to know how to make it, go to Shitaizhuang outside the city to find me in the past two days."

Dropping this sentence, Shi Yiwen turned around and left.

Surprised to walk out of the workshop, Jiang Fangzhong's eyes were full of doubts.

After leaving the workshop with the young master, Xiao Pian was puzzled.

"Young Master, who are you?"

Walking forward casually, Shi Yiwen said without looking back.

"He'll come along!"

Sure enough, in the next moment, Jiang Fangzhong's words came from behind him.

"Childe, please stay."

After entering the house and inviting the son to sit down, Jiang Fangzhong said respectfully.

"Childe, please forgive me for being shallow in the next generation, this flat glass, I really can't make it in the next, listening to what Childe meant just now, it seems that Childe knows how to make it."

"I know how to make it."

said slowly, and then Shi Yiwen said again.

"Not only do I know how to make flat glass, but I also know how to make it more transparent, transparent like crystal, and ...... The price will also be very cheap. ”

Looking at Jiang Fangzhong, Shi Yiwen pursed his lips and did not continue.

Originally, he wanted to find a few glass-making craftsmen, but a factory needs not only a few craftsmen, but also managers.

It's just that people like this will not easily give their own business to others, and then work for others.

"Hmmm......"

Looking at the son in front of him, Jiang Fangzhong couldn't figure out what he meant for a while, and at this moment, he saw this person commanding the maid ring beside him.

"Li'er, take out the mirror and let him see it."

"Yes, young master."

In response, Xiao Lian carefully took out a palm-sized piece of bamboo, opened it, and handed it over.

"Yikes!"

took the bamboo board, looked at it, and looked at the image reflected on it, Jiang Fangzhong almost didn't throw it to the ground.

"This, this is the glass mirror that the palace and the palace said!"

Despite his curiosity, Jiang Fangzhong carefully returned the mirror, lest he accidentally break it.

"That's right, it's smaller, and you can make some bigger ones in the future."

The speaker had no intention of listening, although it was just a casual sentence, but it set off a wave in Jiang Fangzhong's heart, he looked at the person in front of him in surprise, he, he can make glass mirrors!

He was still a little hesitant, but suddenly as if he had made a decision, he knelt on the ground and said.

"The little Jiang Fangzhong is willing to dedicate his entire net worth and Mingkui to the young master's family as a slave, and please don't dislike the young master."

Belch......

Looking at Jiang Fangzhong, who was kneeling on the ground, Shi Yiwen was stunned for a while, and then nodded and said.

"You don't regret it?"

Faced with the first time someone was sacrificed as a house slave, although he was a little surprised, Shi Yiwen was also calm, and in an instant, he weighed the pros and cons in his heart.

What was the reason for his break with the Song family in the first place? Is it because they want to accept themselves as their family, and ordinary people can't compare to the family? It is because the family has many "families".

People have always been like this, although Shi Yiwen once broke with others because they wanted to accept him as a "family", but in the face of other people's contributions, Shi Yiwen did not refuse, as I don't know who said, we are against privileges, but never against our own privileges.

Just like every modern person will scoff at the dedication of the Ming Dynasty, criticizing this as the way to destroy the country, but in the face of others' sacrifice as slaves, they often laugh directly.

Privilege is always a good thing.

No one is against privilege, but equality...... Those who talk about equality are often the ones who crave the most privilege, such as the black people in the United States, and what they call for equality is nothing more than asking for their own privileges.

"No regrets!"

Jiang Fangzhong, who was kneeling on the ground, shook his head again and again and said, in his opinion, this is an opportunity, Shitaizhuang ...... Who else could it be besides the priceless glass mirror and Shi Qianhu in the palace? No matter how you look at it, it's an opportunity for him.

"Do you know that the Shi family has family rules, if you dare to do evil in the name of Shi, you will have your own family law at that time."

said this, but Shi Yiwen thought in his heart, this law is also going to be put on the agenda, otherwise there will be more "family" in the future, and it will be difficult to do.

"Please rest assured, since the old slave is in the Shi family, he will strictly abide by the family law, if he commits the slightest crime, the young master can only ask the family law ......"

Kowtow again, surrender again, and then, everything couldn't be simpler, invite the tooth man in the tooth shop to testify, sign the deed of sale, Jiang Fangzhong became the slave of the Shi family, but only a slave with a foreign surname.
