Antiquity was not without glass.

The oldest surviving real glass is inlaid on the sword of King Goujian of Yue. There are only two pieces left, and it is a very pure blue, almost completely opaque.

The chemical composition of glass at that time was completely different from that of Western glass, proving that it originated independently and was not inherited from the outside world.

However, the ancient glass after that was still mainly based on the cultural exchanges between the East and the West, and the domestic glass was far inferior to the imported products of the West in terms of quality and attention.

The development of domestic glass reached a peak in the Sui and Tang dynasties, with the emergence of fired high-lead glass, which is also known as artificial crystal.

The high-lead glass has high transparency, less impurities, stable shape and excellent quality.

But later, in the Song, Yuan, Ming and Qing dynasties, this technology did not get favorable development, and the firing tendency of domestic glass was still dominated by the imitation of jade, and the import of highly transparent glass was more domestic and less, and the price has remained high.

Moreover, colorless and highly transparent glass has very strict requirements for production conditions, even the kind in the Sui and Tang dynasties, it is usually colored.

As far as Xu Wen knows, this dynasty named Da Zhou does not belong to any of the history he knows, and the craftsman culture here is very special and does not conform to the laws of history. It lacks fluidity and blends the characteristics of different dynasties, as if it is a rigid patchwork of things from different eras, mixed into a chaotic and irregular status quo.

But now, all these characteristics are very consistent with those that appeared in ancient history, and there was nothing new that he was completely unaware of until the middle of the Qing Dynasty.

That is to say, in its history, there may have been high-lead glass, but at most it should only be to the extent of the Sui and Tang dynasties, so that the colorless and highly transparent lampshade should be a foreign product.

But it's here now, not one, but two.

Seeing the craftsman and the handyman next to him pick it up and put it down, it didn't look like an expensive item, it was very casual, just like Xu Wen felt when he was a child and carried it around.

It's not imported but homemade, and it's already in mass production, so that its price has been greatly reduced, and it has reached a certain range of popularity?

This level of highly transparent colorless glass, if it can really be popularized, means that Da Zhou's current industrial development level is much ahead of his imagination!

Xu Wen stared at the two lights, thinking about countless things in an instant. His discussion with Xu San also attracted the attention of some people next to him, and more people noticed them.

"It's beautiful, it's a crystal lamp, isn't it?" said someone in amazement.

"Such a large piece of crystal, ground so thinly, how much does it cost!" The price of a thing has always been one of the focuses of its attention.

"It's not crystal, it's something called glass. Jiang Wangfeng, who was born in a first-class workshop, was a little more knowledgeable after all, and quickly shook his head and corrected everyone's statement.

At this time, he also stared at the two oil lamps, and wrinkled his brows, as if he saw something incomprehensible.

"I know the glass, it's the glass, right?" someone next to him answered.

"Yes and no. Glass is indeed often called glass, but the kind of glass we often talk about using glazed tiles and glazed bricks is not the same thing as glass, and the method of making it is not the same. Jiang Wangfeng shook his head and explained.

Xu Wen glanced at him, making sure that he was thinking the same as himself.

Some sprouts of modern industry can already be seen from Yipinfang, and Jiang Wangfeng is influenced by it, and of course he can also see the technical content of these two kerosene lamps......

Don't forget to ask someone when you come back.

In the morning, Lin Xie left halfway through his words, and he didn't show up in the afternoon. It's a pity that I don't usually know much about these things, so it's rare to have a chance to inquire.

Change tends to be at all levels, but it's usually initiated from the top down.

You can learn more about the upper level of information, and you can also grasp the situation around you more accurately.

At this time, the craftsman in front of him had already agreed on some things and turned around.

The chatter of the two teams disappeared in an instant, and the discipline was as strict.

Qin Lianying lifted a lamp on the table, carried it to the wooden board, and said slowly: "This is the end of the task time, and all the scores have come out." ”

The dim light of the horse lantern shone on the wooden board, illuminating the surrounding handwriting clearly, and everyone invariably looked up and squinted intently.

First, they see the groups with the longest number after the group name.

Beijing 1st Group, Beijing 4th Group, West 1st Group, West 3rd Group and West 22nd Group.

The numbers behind these five groups are obviously much more than those of other group leaders, and they can't be written in one row, but they look like two and a half rows. This undoubtedly means that they have completed the most tasks.

However, if you look closely, you will find that the difference between these five groups is still very obvious.

There are a lot of numbers behind the West Twenty-two group, but all of them are small numbers, and you can see at a glance that they are lucky, and all the small tasks drawn are easy to complete. That's a lot of money, but the cumulative numbers aren't necessarily as big as a big task.

In contrast, the other four groups were completely different.

Their numbers may not all be big numbers, but some are big and some are small, and the first few consecutive numbers in the Beijing group are fifty points. And now everyone already knows that there is an upper limit to the score of the Jingying Mansion team, and the most difficult task is only fifty points.

The Beijing group took several big tasks in a row, and finally completed so many tasks, which is really worthy of Jingying Mansion!

Qin Lianying squinted his eyes for a while, then moved his gaze to Di Lin and them, and nodded approvingly.

Jiang Dongchen received this signal first, immediately smiled easily, and quietly stabbed Di Lin next to him, but Di Lin turned his head with a very solemn expression. In this way, it is not at all like being praised by Shangguan just now, but like being scolded severely.

"What?" Jiang Dongchen asked softly.

Dearin didn't speak, just gestured to him.

Jiang Dongchen was stunned for a moment and looked in the direction of the plank again.

Before, like everyone else, he watched the longest groups. And now, he looks at the overall team of the West Desert, the comprehensive score of each group.

Then, he gasped slightly, his expression as solemn as Dilling's.

There are a total of thirty teams in the West Desert team, with the thirteen who have completed the most tasks, the lowest four, and the average of more than seven.

There are a total of six teams in Jingying Mansion, and the largest number of completed tasks is also thirteen, and the lowest four, with an average of about six, is lower in number than the Ximo team, which is considered a novice.

Of course, there may be differences in the difficulty of the task. But apart from this factor, what qualifications does Jingying Mansion have to take a stand in front of others?

Then, Jiang Dongchen quickly mentally calculated the total score of each team, and immediately gasped slightly.

The current total score of the Beijing Group is 577 points, ranking first among the six groups in the Jingying Prefecture.

The current total score of the West Group is 581 points, which is just four points more than them, which is slightly exceeded.

And the most shocking thing was the West Second Group, they only completed four tasks in total, the least of the thirty groups of the West Desert Team, but their total score reached 675 points, nearly 100 points higher than them!

This means that the four tasks they drew should all be relatively difficult, but they all completed them successfully, and they should have completed them quite satisfactorily, otherwise they would not have received such a high score.

The basic arithmetic of Jingying Mansion was no problem, and in an instant, all of them were silent, staring at the scores of the two groups, unable to speak.

This means they lost.

They actually lost!

On other occasions, the ordinary craftsmen of the Western Desert Team who have no identity background, in the face of these royal craftsmen from Jingying Mansion who are directly managed by the Ministry of Industry, may not even have a chance to come forward and speak.

However, today, the two faced each other, and they actually lost!

When they find this, the word shame may not be able to express the shame in their hearts.

"They have a high score for their tasks, and ours has a low score. They already took advantage, what is there to say?" After a long while, Long Qi finally held back a sentence.

"Don't say it, it's not a shame. Jiang Dongchen glanced at him, lowered his voice and said impatiently.

There is a gap in the score, not so much because they lost, but because they saved their respect!

The starting point on both sides is too far apart, and they shouldn't lose no matter what conditions are attached.

Long Qi didn't speak anymore, they silently listened to the low laughter coming from the other side, very congested.

At this time, Qin Lianying raised his head and swept his gaze over them again.

He smiled slightly, and his other hand, which did not carry the lantern, lightly touched the wooden board, and asked, "Do you see this circle?"

This is exactly the one that the monkey asked before, Qin Lianying didn't answer at that time, but then he specifically mentioned it.

This indicates the result of the review. All those that are not marked with a circle are considered to have not passed the review and should not be scored. ”

"!!!" All the members of the Jingying Mansion were shocked.

Visible to the naked eye, there are far fewer circles on their scores than on the opposite side!
