Chu Tianxiu didn't know that Emperor Xiang Yanran was brewing the next big move, intending to let him take this super bad blame.

When he returned to Yuyuan from the academy, he started to tinker with Li Yu, Zuer and Di'er in the courtyard.

He remembers the technique of refining glass.

But I have never tried it, and there was no craftsman in the Great Chu Dynasty who could make glass.

The technique of refining glass seems difficult. If he doesn't refine it, no one will know how to make real glass in the next few hundred years.

Actually... surprisingly simple.

This thing is the same as the technique of Hunhou Paper, and it can be understood at a glance... But if you don't click this, you will never be understood.

Chu Tianxiu first built a high temperature-resistant earth furnace kiln in the open space of Yuyuan that can withstand high temperatures of 1,500 degrees.

Then grind the quartz sand and hexagonal diamond-shaped quartz into sand.

There is also the most critical natural alkali, which often appears in salt lakes.

As well as auxiliary materials such as limestone, put them in and smel them together.

Use a blower to heat the furnace at high temperature.

Of course, you need to prepare some iron tools for cutting high-temperature glass in advance.

During this period, Danyang County has made large-scale steelmaking. The county town is full of small earth furnaces, and the technology of small earth furnaces has been very good.

Moreover, various iron tools have increased greatly, such as iron pipes, iron scissors, iron plates, iron hammers, etc., with a wide range of products.

Zuer and Di'er were pulling the blower, filling the back with fragrance, heating the earthen kiln.

After one hour.

Li Yu was surprised to see that all the quartz sand in the furnace had melted into a ball of liquid.

Chu Tianxiu picked out the ball of solution with an iron rod, placed it on a flat iron plate, and pressed it hard. It turned into flat, translucent glass.

Annealing and cooling, and translucent glass, a piece of one foot in size, came out.

It's just that there are impurities inside, with a light blue color, and it probably contains copper ions. The impurities must be removed to be as transparent as possible.

Chu Tianxiu thought to himself.

Use scissors to cut the uncooled glass into a round mirror.

"Oh my God!"

"After burning like this, the glass has been refined!"

"What a beautiful glass!"

All three girls were shocked.

After the glass annealed and becomes cold, they can still see the light blue figure opposite through the light blue glass.

So amazing!

This is definitely a rare treasure, a luxury that is priced at gold.

Not only the nobles of Da Chu, but also the nobles all over the world love this luxury goods. Just this round light blue mirror is sold for at least a hundred taels of silver.

"This doesn't count. I'll make a blue glass for each of you!"

Chu Tianxiu smiled.

Colored glass is naturally not suitable for mirrors. However, it is best to use it as other daily utensils.

Blowing a glass cup is the real "epoch-making high-tech".

He took a hollow iron pipe in the middle, and a ball of melted high-temperature glass at one end, and then began to blow vigorously at the hollow iron pipe.

I saw that at the other end of the iron pipe, the glass solution began to bulge and soon turned into a ball.

Li Yu, Zuer, Di'er, and the three girls all stared at their beautiful eyes.

They could never imagine that the melted high-temperature glass liquid could actually blow it by the mouth!

Then he cut the opening with scissors, and then used iron pliers and rods to pinch and pinch!

Knead and rub!

With skillful techniques, the hot glass balls were scrambled into beautiful goblets.

"Wow~, it's so beautiful! Husband, can it be made into other styles?"

Li Yu was shocked.

This light blue cup has a dreamy light blue color, and it is transparent.

Drinking wine with this cup may be like a dream.

"Of course, it can be done even by carving it into a phoenix."

Chu Tianxiu made three light blue cups in one breath, and each person gave one.

The three girls can't let go of their love.

Chu Tianxiu fiddled with a few more beautiful glassware and then stopped.

The technical problem of refining glass is not a problem. He only needs to build a large glass workshop and recruit dozens of honest and reliable craftsmen to produce glass in large quantities.

Of course, how to remove various impurities from glass and create glass of various colors and transparency.

These also require careful study by specialized glass craftsmen.

It was just a matter of building a glass college, recruiting craftsmen's children to study, and conduct research, development and production.

"Yu'er, tomorrow you buy a piece of wasteland outside Jinling City and build a glass workshop. This is huge profits, making more money than making paper and iron."

Chu Tianxiu said.

If you exclusively monopolize this technology, you can maintain expensive prices for at least one or two decades.

Unless there are too many glass workshops and are everywhere on the market, glass will be worthless.

"Well, I'll go find a place today."

Li Yu nodded excitedly.

It is estimated that it will cost no more than 10,000 taels of silver to buy wasteland and a workshop. However, glass is a luxury item, and any piece can be sold for dozens or hundreds of taels of silver.

As long as anyone in Jinling City uses it, brag about other kings, clans, nobles, princes, grandchildren, and noble ladies, who don’t want it!

The return is very, very fast.

...

The guards of the royal palace reported that a large eunuch from the palace came to see him.

Chu Tianxiu was a little strange.

Ever since he started playing with eunuchs in "The Story of the Stone", the eunuchs have had a bad relationship with him.

What is this eunuch looking for him?

Soon, a large eunuch from the palace came to Chu Tianxiu with a few little eunuchs, with a gloating smile and said, "We have met the little marquis in our family. The emperor sent the oral orders to order the little marquis to preside over the morning."

He heard a little whine from Cai and the eunuch, and it seemed that Xiao Hunhou was going to be in trouble. In addition to this difference, he was really unlucky and offended too many people.

Moreover, Xiao Hunhou took the initiative to provoke this bad guy. In order to have the best name in the palace examination, Xiao Hunhou did not hesitate to offend the world's powerful people.

"What memorial is submitted?"

Chu Tianxiu is strange.

"It is the strategy you wrote in the palace examination. You know what you wrote, and the emperor knows it. Your first name in the palace examination is not for nothing.

Of course, our family is not clear. The emperor said that, we have brought it. As for how to do it, you should be more at ease and don’t put yourself in it!"

After the eunuch said that, he left with a swagger without waiting for Chu Tianxiu's reply.

Who dares not to listen to this emperor's oral order?!

He, the eunuch, is only responsible for conveying it.

What Xiao Hunhou did next is his own business. The emperor asked Xiao Hunhou to take the blame and violate the holy will, but there was no good ending.

Chu Tianxiu was shocked.

In just a few months, the Emperor is about to launch the "Plan forbidden Privately Forged Coins" so soon?

He had just traveled to Da Chu, and the emperor gave him an imperial edict to Prince Ping's Mansion to be a son-in-law. He had not yet figured out the situation, and he had not even figured out the copper mine in Li Yu's fiefdom.

He only wanted to make a big splash in the palace examination, be proud, and get a high-ranking official, so that he would offer a "Plan forbidden to cast a private bronze coins" in the palace examination.

Until now, the copper mine in Ma'anshan, Danyang County has not been dug up yet!

Will it be handed over to the court?

It’s nothing to pay the copper mine in his own country, but he already has many ways to make money.

Papermaking, Danyang County’s large steelmaking, and this newly launched glass workshop. The income from a copper mine will not affect his continued luxury life as a young marquis.

But, offend people!

How many copper mines of princes, princes, and nobles cannot create copper coins privately from now on, so how much loss will be. It would be strange if they are not angry.

A headache!

If he took the blame, he would probably have to worry about being assassinated when he went to bed!

But he was still the one who committed suicide and gave it to him.

Seeing that he was so fierce, the emperor immediately gave him a palace examination and made him the magistrate of Danyang County... But now, the emperor wants him to fulfill this proposal.
Chapter completed!
