I was watching short videos and was seen by ancient people

Chapter 260 Necessary for Time Travel—Making Glass ()

"Dream of Yesterday: In fact, glass fired with sand will actually have some ionic impurities, some of which contain iron ions and the like, and the color will be different, so it may not be washed away with strong salts or acids. The previous method seemed to be to add manganese dioxide. 》

When people from all dynasties saw the comments on the sky screen, they looked at the glass products in their hands.

Although the color of the glass products in their hands is a little off as mentioned on the canopy, in their opinion, they are already the best among the best.

However, this kind of the best of the best is still a defective product in the eyes of later generations. This makes them unable to imagine how exquisite the glass products of later generations will be?

Some people didn't believe what was said on the canopy. They didn't believe that the rear glass was even more exquisite.

In their view, only crystals in this world can be so pure, and it is impossible for glass products to meet the requirements of crystals.

In order to prove that the comments on Tianmu were false, they followed what Tianmu said and carried out various picklings on the quartz sand, the raw material for making glass, before starting to refine the glass.

The finished product is, as it says on the canopy, much purer than before.

Just looking at the comments on Tianmu, this is not the best. The best way is to add manganese dioxide.

However, the people of this dynasty were confused as to what manganese dioxide was, and they could only experiment again and again, hoping that they could find such a substance.

"Phobia of Insufficient Force: When making glass in ancient times, you must pay attention to the dynasty. Before the Song Dynasty, you could make it, and it was 100% profitable. But after the Song Dynasty, you have to look at your reputation. After all, glass was not a rare thing at that time. 》

"Northern Scenery: It was fine after the Song Dynasty, and the glass used for communication between the East and the West in the Ming Dynasty did not have this kind of light transmittance. 》

People after the Song Dynasty looked at the comments on the sky screen and laughed.

If it were in the past, their glass at this time was not as rare as before, but it was still a valuable item.

But now that a video of making glass appears on the sky screen, I'm afraid this glass is no longer a strange species.

As for the light transmittance of glass, the canopy has taught them everything, what else can be said?

I'm afraid that if the time traveler travels to their era, even if he makes glass, he won't be able to make much money.

However, they still hope that there will be a time traveler who can travel to their era, so that he can lead them to make more things.

"Sunny Little White Horse": [Secret Observation] That's hard to say, Pre-Qin... The sword of Gou Jian of the Yue Kingdom... was inlaid with glass [Secret Observation]. 》

Spring and Autumn Period and Warring States Period.

Gou Jian, the leader of the Zhao Kingdom, frowned when he saw the video on the sky screen, and his heart was filled with a bad premonition.

If he had seen the video on the sky screen before and saw Qin Shihuang's tomb being dug, he would have just gloated.

So now that he saw the glass inlaid in the sky that mentioned his accessory sword, he just felt that the people of future generations had no idea of ​​fearing his ancestor.

That was an accessory he carried with him. Even if he died, it should be with him in the tomb. How could it be known to future generations?

This must have been because his tomb was dug out, so that the people of later generations knew so clearly that he had glass products on his sword.

He felt that he needed to find another burial to prevent future generations from doing unfilial things.

Then he sent a large number of magicians to find a new tomb for him in the Chu Kingdom.

Moreover, he also made a request for the location of the mausoleum, requiring that it must be in a remote place. He was very afraid that unfilial descendants would dig up his mausoleum at every turn!

"Love in the Ming Dynasty: In fact, we should think about how to make it into a glass mirror. After all, such clearly visible delicacy must have been popular in ancient times. So the question is, how to make it into a glass mirror [Thinking]? 》

"Snowflake Piaopiao: Yes, not only can it be made into glass mirrors, but it can also be made into telescopes, reading glasses and other items.

If I traveled back in time to ancient times, the glass would have to be built in a greenhouse first. After all, it would be too uncomfortable to eat only radishes and cabbage in the winter when fresh vegetables are not available. 》

When people from all dynasties saw the comments on the canopy, they never imagined that such glass could be used to make such things.

What they were disappointed with was that there was no information on how to make the glass mirror on the canopy. Although the bronze mirrors were clearly visible at this time, the human figures they could create were brass in color after all.

And if there really was a mirror like the one mentioned on the canopy, I'm afraid people would go crazy.

This has made many businessmen ready to take action. They hope that it can be broadcast on the sky screen. How do you know the method of glass mirror?

At the same time, they also want to know, how to make reading glasses and telescopes?

After all, these two things are very useful just by listening to their names.

Presbyopia is a normal thing for people in old age, but how to treat it is a headache for doctors.

However, what they said on the screen was that they could be cured by just wearing such a mirror. This was beyond their expectation.

And the telescope is better understood, it is to bring the distant scenery into front of your eyes.

If they had this kind of item in their time, they would have an advantage when marching and fighting, and they would definitely be victorious in every battle.

However, after seeing that glass could be used to make greenhouses, people from various dynasties thought about it and found that it really could be done.

The greenhouse made of this glass is like building a transparent house for those dealers.

Not only can it allow the growers to grow normally, but it can also increase the temperature in the house.

And when it's particularly cold, we can also provide heated kangs for those dealers, so that they can eat food in the cold winter.

Thinking of this, some people started to take action. After all, this is also a good way to make money.

The only thing that gives them a headache is that the cost of such a greenhouse is too high. They are afraid that the price of vegetables will be extremely high by then, and they don't know if anyone will buy it.

So they went to the vegetable market and discussed with the housekeepers of the high-ranking officials.

After discovering that there was indeed such a demand in the kitchens of those high-ranking officials, they felt relieved and began to take action.

So in each dynasty, greenhouses were built one after another, and they were filled with various vegetables, so that there were many more green vegetables in the winter, which was originally lacking in green.

When the emperors of various dynasties saw what was said on the sky screen, they directly ordered the craftsmen to conduct experiments.

Whether it is a mirror, reading glasses or telescope, they are all they need.

The mirror was requested by their beloved concubine, but the reading glasses were needed by the veterans in the court.

The telescope can give them an advantage in the war, and the glass greenhouse can allow them to eat more vegetables in the winter.

They can imagine how happy they will be in this cold winter, being able to eat vegetables that can only be eaten in other seasons.

To achieve this goal, they had to build several greenhouses.

So the emperors of various dynasties issued orders to let the craftsmen make more glass and build several greenhouses.

Some people even thought that the glass could inspire the window paper, and they quickly had it replaced.

At the same time, it also made them feel the warmth brought by this sealed house and the heated kang.

　Happy New Year's Eve everyone!

　　I hope everyone will have all their dreams come true in the new year!
