After several quarrels, not only did the daily newspaper sell out of stock, but there was almost no one in the capital who didn't know about silver and glass as mirrors.

What no one knows is that even Chu Xu, the crown prince in the East Palace, is worried about this glass mirror.

He looked at the newspaper coming in from outside the palace, he was curious and expectant, and couldn't help but ask the eunuch who was waiting beside him: "Wang Tai, do you say that this silver and glass can really be made into a mirror?" ”

Few people know that Prince Chu Xu also likes to look in the mirror.

Maybe it was because he was fat, and Emperor Yong'an always disliked him for not looking like him, so he hit him badly.

So Chu Xu would secretly look in the mirror every day, trying to find out the similarities with Emperor Yong'an from his face, so as to comfort himself.

Now he wants to lose weight every day, and he looks in the mirror more often.

Every day, I have to secretly take out the mirror to see if my face has been cleared.

It's a pity that after several months of reduction, it doesn't seem to have any results.

Every time Chu Xu looked in the mirror, he couldn't help but be disappointed.

Now that he suddenly heard that silver and glass could be made into mirrors, he couldn't help but pay attention to it.

At the same time, he was curious about the mirror in Queen Zhang's hand.

It's a pity that he is the crown prince, and he must lead by example and have the appearance of a prince.

You can't just go to Empress Zhang's palace and ask her to borrow a mirror to see, right?

That's too unproductive.

Chu Xu was very curious about the mirror in Queen Zhang's hand, but he didn't dare to go, so he could only hold it silently in his heart.

It wasn't until he saw the news in the newspaper recently that he started thinking again.

If silver and glass could really make a delicate mirror, he would really want to see it.

However, he had only heard of the use of copper to make mirrors, and had never heard of silver and glass being made into mirrors.

I don't know how it was done.

The more Chu Xu thought about it, the more curious he became.

Wang Tai said cautiously: "Now that it has been published in the newspaper, I think it can be done." It's just that the slave maid has limited knowledge, and she really can't imagine how to make a mirror out of silver and glass. ”

Chu Xu said kindly: "Hey, it's not your fault, I can't think of it, it's not your fault." ”

After a pause, he couldn't help but sigh with emotion: "If this mirror is really made, Gu really wants to see what it will look like." ”

Wang Tai didn't dare to speak again this time.

Liulifang is the private property of Princess Qin, where does he dare to talk more?

……

Just when "Beijing Daily" and "Beijing Gossip" were fighting in the newspaper, Liu Fang excitedly took a long box and asked to see Emperor Yong'an.

Emperor Yong'an soon summoned him.

After Liu Fang went in with the box, as soon as he finished saluting, he couldn't wait to say: "Your Majesty, after the lens made of glass is polished, it can really be used!"

The slave had ordered someone to make clairvoyance, and compared it with a clairvoyant made of water jade. Although the effect of the glass lens is slightly worse, it is entirely because the glass is not transparent enough.

If you can burn more transparent glass, the lenses you will make will be no different from the best jade lenses! Your Majesty, please look! ”

Emperor Yong'an had actually been mentally prepared for a long time, but when he didn't see the result, he was always a little uneasy in his heart.

Now that he heard Liu Fang's words, the heart that had been hanging could finally be put back into practice.

Emperor Yong'an was excited: "Take it to me!" ”

When Gonggong Li heard this, he immediately held the box and handed it to Emperor Yong'an.

Emperor Yong'an picked up the two clairvoyants, and after comparing them, he found the difference.

Because the glass lens is not transparent enough, the color is a little distorted when looking at things.

However, the interior is still too small to be used.

If you want to really test the effect of two clairvoyants, you have to go to a high place.

So Emperor Yong'an couldn't wait to walk out of Emperor Yong'an with clairvoyance, came to a high-rise building, and began to look into the distance.

This time, the perception of the two clairvoyants was even more obvious.

However, Emperor Yong'an was still very satisfied.

Although there is a gap between the clairvoyance made of this glass lens and the clairvoyance made of the best water jade, this gap is not particularly large.

Compared to the rare and hard-to-find best water jade, this glass lens is too easy to make!

It can also be manufactured in large quantities!

Emperor Yong'an immediately asked Liu Fang: "Is this glass lens easy to manufacture?" How much can be produced in a day? ”

Liu Fang had been prepared, and he had guessed that Emperor Yong'an would definitely ask a lot of questions before he came, so he had already prepared the answers.

After hearing Emperor Yong'an's words, he immediately smiled and said: "Back to Your Majesty, this glass lens is quite easy to manufacture, as long as the glass is melted and put into the mold, a large number of rough embryos can be pressed.

It's just that the coarse embryo pressed out can't be used directly, and it must be annealed and ground before it can be used to make clairvoyance.

Grinding is time-consuming, but the slave has recently switched to an assembly line production, and a craftsman is only responsible for one step, which has improved the efficiency a lot.

Based on the current output of the War Bureau, it can create twenty clairvoyants in a day. If you increase the number of people, you can expect to increase the output. ”

"Twenty a day?" Emperor Yong'an was surprised, "Are you sure that you can create twenty clairvoyants in one day?" ”

This yield is much better than before!

Liu Fang said respectfully: "Slaves and maids don't dare to bully the king, in the past, each craftsman was responsible for creating a water jade lens, because the shape of the water jade is strange, and it is extremely time-consuming to polish, so the output of this clairvoyant has not been able to go up."

Nowadays, it can be pressed into a lens rough embryo with glass, which saves a lot of polishing time, and after changing to an assembly line, each craftsman only needs to be responsible for one step, and he can quickly become a skilled hand, which can naturally improve a lot of speed. ”

When Emperor Yong'an heard him say this, he couldn't help but be interested: "You take me to see!" ”

Liu Fang didn't dare to disobey, so he had to take him to the War Bureau to check the clairvoyant's assembly line.

After Emperor Yong'an arrived, he found that the craftsmen inside really performed their own duties and did not interfere with each other, and each craftsman was very skilled in their work.

Looking at the clairvoyants produced, it is even more joyful.

He glanced at Liu Fang with satisfaction and praised: "Liu Fang, you have done a good job this time, and I am rewarded." By the way, how did you come up with this assembly line? ”

Liu Fang hurriedly said: "Back to Your Majesty, this assembly line production was actually proposed by Liu Feng, who burned the glass. According to him, it seems that the earliest proposal was made by Princess Qin. ”

Emperor Yong'an couldn't help but be stunned: "It's actually her." ”

He was really stunned.

Although he always knew that he was discerning, he chose a good daughter-in-law for his son.

But he didn't expect that the daughter-in-law he picked was so good!

By the way, Liulifang seems to be making mirrors recently, and I don't know how it is doing.

When the mirror is made, his mirror can be replaced with a new one.
