Yijun went to knock and found that the sound was crisp and not like pottery, so after understanding the situation....

Yi Jun used his little brain and began to burn some strange stones, trying to see if he could burn an artifact.....

The flames in the hearth were roaring, and the flames in the mouths of the scourge were whirring.....

I don't know what mess was added, and then with the help of the scourge, with the help of five friends, including Yu Liang, Yu Chui, Yu Zhu, Yu Pan, Xiong Tao and Xi Zhong.....

A somewhat muddy, but somewhat transparent, strangely shaped and inferior-looking utensil appeared in front of everyone's eyes.

"What is this?"

Yi Jun stared, gently tapping on this ancient glassware, he felt that this thing was very fragile, of course, the pottery was not strong, it was all goods that would rot when it fell.

However, compared to the pottery and the two strange pottery that make a crisp sound, this thing is obviously better in terms of material, but the shape seems to be burned out, and it is obviously fired according to the appearance of standard pottery, but I don't know which link is wrong.

Xiongtao is very interested in this, very excited, including the two strange pottery, this is a major breakthrough in the pottery process, obviously the production of these three new pottery is an accident, the first two are natural accidents, the latter is a human accident, after all, Yijun does not know what he is burning.

The scourge stuck out their tongues and looked up and down the glassware.

"Who remembers what I burned?"

Yijun asked a few friends, but Xi Zhong jumped out and said that he had written it down.

————

So, when Yu Zai returned to the tribe, what he saw was Yi Jun holding a strange round glass piece in his hand, and he was taking pictures everywhere with his eyes sticking to them.

Yu Zai was stunned for a long time before he suddenly reacted, what Yijun was holding in his hand didn't seem to be something that appeared in this era!

"What is this!"

Yijun saw that Yu Zai had brought people back, and understood that the flood control work should be over, during this time he was not aware of what was going on outside the window, and was only in the furnace, Yi Jun told Yu Zai that when he was firing things, he was very surprised to find these things.

The little butterfly on the Yandi bluestone flapped its wings, and the trajectory of the years changed dramatically.

When Yu Zai came to the blacksmith shop and saw the two objects that were introduced as special pottery, as well as the strange pottery that was translucent and cloudy, Yu Zai knew that he had unlocked another technology, and he had unlocked it unintentionally.

Yijun created the history of mountains and seas.

The primitive glass that the ancient Egyptians had mastered as early as 2,000 years before the present mountains and seas, and the oval crystals that the ancient Sumerians accidentally obtained at the same time, that is, the primitive magnifying glass, Yijun inadvertently brought glass and "optics" to the history of mountains and seas in advance.

The earliest glass was an accidental product of the ancient Egyptians when they fired pottery.

The earliest optical discovery should be in the Tangting Mountain in the "Book of Mountains", this mountain is also the Nanshan Sutra system, with water jade on it, also known as water jade, jade ying, that is, crystal, and white quartz called white quartz.

The author of the Book of Mountains can not be verified, and the Book of the Sea, the author of the Great Wilderness Book generally believes that it is different, the oldest author of the Book of Mountains guesses, it should be Boyi, because the Book of Mountains records the flow of the water system, following the Boyi of Dayu to control the water, he recorded these water systems for a purpose.

Boyi discovered primitive optics in Tangting Mountain, but limited to the era is only a record and not too in-depth research, compared to the ancient Egyptians have entered the dynastic period at this time, the Sumerians at the end of the city-state era, the mountains and seas are still the era of tribal alliances, the productivity is not enough and the accumulation of science and technology points is insufficient, so that it is impossible to enter the next era....

A large number of applications of optics were in the Spring and Autumn Period and the Warring States Period, when the names of Yangsui and Huoqi were crowned on copper and other things, including Mozi's research on the world's first small hole imaging experiment, as well as basic optics such as light propagation along a straight line, which completely revealed the role of optics.

Mozi has studied optics and mechanics, as well as engineering, and has summed up eight experiences in optics alone.

There is also what Keiko said about "the shadow of the bird has not moved", which is a theoretical summary in optics, but Mozi is good at research and Keiko focuses on raising the bar, after all, Keiko's main job is the Xiangguo of King Hui of Liang, raising the bar is the main business, and research is just a hobby.....

Yu Jae snatched Yoshikyun's lens, which was a convex lens, and the light rose in Yu Zai's hand, and then moved the light to gather on the convex lens, followed by aiming the convex lens at the ground.

Because of the intensity of the sun, in just a few moments, a fire suddenly burst out on the ground!

"Huh?!"

Yijun clapped his hands: "Yes, yes, that's it, I found out before that this thing can make fire by gathering light, what is the principle of this, the same as the heat of the Qi Refiner's Yang Accumulator?"

"I'll tell you about it later... But how do you make it? And this, this is not pottery!"

If you put down the lenses, too strong light will damage this thing if you focus it for a long time.

Coming to the two special pottery, these two things belonged to the accident when they were fired, and Yu Zai recognized what they were.

It's porcelain!

There is no doubt that it is indeed porcelain, but it should be primitive porcelain, and the former teammates, archaeologists, took them to see these things, saying that they were things from the Shang and Zhou dynasties, and the main firing material was kaolin, which is common in nature.

"There are actually a few failures..."

Xiongtao tells the story of these two things before they appeared, and when he fired them, he used the method of learning, plus the method he had learned from his eldest brother before, and made them out of two phases.

Those pottery of particularly good quality, after Yu Zai looked at it, he found that these were stoneware.

The so-called stoneware, as the name suggests, is a sintered stone, something between pottery and porcelain, also known as stone porcelain, that is, a large water tank in the home, or even a purple clay pot, these things are stoneware.

Xi Zhong handed over the recorded Jane with Cangjie characters written on it to Yu Zai, and what was recorded on it was the stones that Yijun threw in and burned.

"Good, good!"

Yu Zai sighed with emotion, I didn't expect these guys in the blacksmith shop to really make a big deal, glass, stoneware, pottery, primitive porcelain, these are all related to the context, find one, in the process of firing, you may find a second, like an accidental superposition, constantly deriving!

However, this powerful thing was evaluated by Xiongtao as sturdy, but it was too shoddy.

"I remember Chonghua .... Oh, Wu, Chonghua is the big brother of the elephant, you should not forget...."

"Chonghua once helped change the pottery kiln in our Kongsang clan, you don't know, the kind of pottery he burned, the great wizard of our tribe, said that it was 'the blessing of earth and fire', so our tribe all learned his pottery making method. ”

"The pottery I'm firing now is also using some of his methods, plus some of your methods here, and finally came out..."

"It's a pity that this kind of black pottery, only the soil and sand near the big river, made of it, is the best!"
