Watching short videos of beautiful women dancing, the ancients were all shocked

The more you study, the more you will learn.

While the emperors of different time and space were studying gunpowder and fine salt, the study was still going on in the sky!

[I have told you about the methods of making salt and gunpowder before. I believe everyone has mastered them, but these two technologies can cost you your life in ancient times! ]

[But don't worry, I have another good way to make money for you! ]

[Want to know what was the most profitable thing to do in ancient times? ]

A crystal clear and beautiful glass cup suddenly appeared in the sky screen, showing in front of everyone like a precious work of art!

[The answer is "glass"! 】

【Look at the monk Sha in "Journey to the West". He was demoted to the mortal world by the Jade Emperor just because he accidentally broke a glass cup. He was tortured in the Flowing Sand River and suffered from the pain of flying swords piercing his chest every day. This shows how valuable glass is! 】

【So, "glass" is definitely one of the most popular items in ancient times! 】

【Let's teach you how to make glass below! 】

At this time, under the sky!

Tang Dynasty.

Li Shimin looked at the glass cup on the sky and liked it at first sight!

Li Shimin's eyes showed his love, and he couldn't help but sigh: "This glass cup is really dazzling and a rare treasure. If I can get it, it will surely add to the glory of my Tang Dynasty."

He thought that if such a beautiful thing could be mass-produced in the palace, it would surely show the prosperity of the Tang Dynasty.

So, Li Shimin stared at the sky to learn how to make glass.

Colored glaze is also available in the Tang Dynasty, but it is rare!

It is even more precious than gold.

Above the sky!

[Colored glaze originated in ancient Egypt, and it cheated us of a lot of gold on the Silk Road! ]

[Today, I will teach you how to make it! ]

Under the sky, people from all time and space, whether they are royal nobles or wealthy merchants, took out their little notebooks and recorded them carefully.

After all, the value of this thing is more real than gold!

…

[If you want to make colored glaze, you must know what materials it needs! ]

[Its main raw materials are quartz sand and soda ash! ]

[If you can't get quartz sand, you can use sand instead. ]

[To make colored glaze with sand, you first need to filter the sand, which can be filtered out through an hourglass. The finer the better. ]

[Alkaline substances can be obtained by burning oat malt to obtain plant ash, and then the plant ash can be soaked, filtered, and evaporated to obtain white alkaline substances. 】

【You also need a crucible, pour the sand into the crucible, add alkaline substances and mix evenly, then put the dry pot into the furnace for calcination. 】

Note that the temperature needs to be heated to above 1600°C to make it melt into liquid. 】

【Some people may ask, was the temperature so high in ancient times? 】

【Of course, first of all, you need to choose high-quality coal, add appropriate blasting devices and coal kiln structures, and you can raise the temperature very high! 】

【After the liquid is fully fired, it can be taken out and shaped. 】

【You can also put it into a pre-made mold, then press it to shape it, place the molded object and wait for it to cool, and wait until it reaches sufficient hardness, and then quench it twice. 】

【Make the inside and outside burn bright, and make its internal structure more uniform, so that the quality of the glass made in this way is better in all aspects! 】

【Have you paid tuition? 】

【If you travel back to ancient times, this is an absolute means of making a fortune! 】

【Now you have money, weapons, and salt. If nothing unexpected happens, you can recruit soldiers and horses in the next step! 】

【Note that if you travel to the Tang Dynasty, Qin Dynasty, Han Dynasty, and Ming Dynasty, it is recommended that you hold on to the emperor's thighs firmly! 】

【If you travel to the Qing Dynasty, the Five Dynasties and Ten Kingdoms, and the Jin Dynasty, you must rebel. Whether you can win or not is not a problem. You must not lose face! 】

At this time, the barrage on the sky also rolled up!

——"I learned it. There is a big truck in front. Brothers, I'll go first!"

——"Good brother, you go first, and I will be there soon. The coordinates are in the Tang Dynasty!"

——"Brother, whether you form a team or not, I will also be in the Tang Dynasty!"

——"Add one!"

——"Just a weak question! Did you wear it, brother?"

——"Don't ask, it's probably that you went down to drink soup!"

At this time, under the sky.

Countless royal nobles and wealthy businessmen have begun to manufacture!

When the emperors saw what was said on the sky curtain,

All of them smiled!

"Get rich? That's impossible!"

"Revolt? Even less!"

Tang Dynasty.

After reading it, Li Shimin started to create Tang Dynasty Glass Co., Ltd. with Gongsun family, Cheng Yaojin and a series of ministers!

Of course, the boss is still Li Shimin, and they are responsible for providing money and people!

Li Shimin still takes the lion's share of the profits, after all, who lets him be the emperor.

The main point is that you don't spend a penny, you get it for free!

Then Li Shimin looked at the barrage flashing on the sky with a smile, and these people from later generations actually expressed their desire to come to his Tang Dynasty.

It seems that his Tang Dynasty is still very attractive!

"When you time travelers really come to my Tang Dynasty, I will give you a big surprise!"

Li Shimin's mouth corners slightly raised, and his eyes flashed with cunning light.

He imagined that when those time travelers came to the Tang Dynasty and saw a room full of glass, black gunpowder, and fine salt, they would definitely be shocked!

I couldn't help but feel a little bit of anticipation!

"I want to see what your expressions are when the time comes!"

And at that time, the expressions on their faces must be very interesting.

Thinking of this, Li Shimin couldn't help but laugh out loud!
