My whole family has crossed with Goldfinger

After half an hour, the results of the exam came out, and Mr. Liu announced the list of admissions in public.

A total of 38 students took the exam, only two failed the exam, and the others all passed the exam successfully.

Xu Dajun is listed below. Hearing Mr. Liu talk about various matters of admission, he was very happy. Unexpectedly, he really passed the exam!
After being admitted to Honglu Academy, from tomorrow onwards, they will enter the academy to report for admission, and the students of Honglu Academy must live in the academy and have two days of rest in a month before they can go down the mountain. If you want to go down the mountain, you must ask your husband for approval.

As the largest academy in the world, Honglu Academy is difficult to pass, and the treatment is also excellent. All the students of the academy are free of board and lodging. They only need to bear the cost of their own pen, ink, paper and inkstone, and the cost of buying books. cost.

Of course, as long as the student from a poor family is diligent, the required books can be copied for free in the library of the academy. The library provides the pen, ink and paper for copying the books. Books to get pen, ink, paper and inkstone.

In this way, it is almost impossible to spend any money.

It can be said that this kind of treatment is really hard to find elsewhere.

Not to mention, although Xu Dajun is not short of money for pens, inks, papers and inkstones, he also plans to go to the library to copy books in exchange for pens, inks, papers and inkstones. Copying books can also learn knowledge, and it is also a good time to practice calligraphy!

After receiving the pair of cards representing the students of Honglu Academy that day, they can go down the mountain, go down the mountain to pack their luggage, and go up the mountain tomorrow to go through the admission procedures.

……

While Xu Dajun and Fang Congyun were writing and answering exams at Honglu Academy, Xu Yinyin, who was far away in Yiyang Mansion, finally received the good news from Commander Yang.

Looking at the transparent white stone in front of her, Xu Yinyin smiled happily, "That's right! This is calcite!"

"Master Yang, where did you find this? How many?"

The man sent by Commander Yang replied: "Chizhou! My lord has a good friend who is now the director of the Chizhou mine. This calcite was found from the quarry under his jurisdiction. At least, they can’t use it, my lord wrote to say it, and over there sent my lord two big baskets, Mr. Xiang, do you think it’s enough?”

These two baskets were enough for her to do experiments, Xu Yinyin nodded, and immediately got someone to bring back her thanks and send him away, then she couldn't wait to get busy.

The Du family pottery kiln where the workshop cooperates to customize pottery pots is in the northern suburbs of the city. Xu Yinyin has been there a few times before, and she has already discussed with the head of the Du family, and if there is a chance, she will borrow his pottery kiln.

No, even if Xu Yinyin asked someone to go over and say something, she herself rushed to the other side. On the other side, the master of the Du family greeted her personally, saying that a kiln had been specially vacated for the use of Jiacheng Township Lord.

Everyone in Yiyang Mansion knows that the Lord of Jiacheng Township likes to tinker with strange things that no one else can make, not to mention all kinds of soaps, shampoos and creams.

Now I want to borrow his pottery kiln, and I don't know what to make. Master Du is also very curious.

The other party was Lord Jiacheng, and he was not unhappy. He not only lent the kiln, but also specially reserved a few kiln burners to help Lord Jiacheng. , but not good.

Xu Yinyin has studied the recipe repeatedly, and is familiar with the production methods, but she has not tried it.

At this moment, I also intend to die until I can't make it, so in order to facilitate the busy work, I specially changed into a suit of clothes that are convenient for working, and tied my hair into a bundle, wrapped it in a cloth, looked at it from a distance, and said yes A country woman is not too much.

To make glass, each raw material has a specific ratio, more or less will not work, and we must strive for precision, so Xu Yinyin does everything by herself, and does not intend to fake it to others, because she is afraid that there will be mistakes. She didn't know which step went wrong, so she did everything by herself, so she knew it.

First of all, several kinds of raw materials - quartz sand, limestone, calcite, etc. - are first ground into powder, and then prepared according to the proportion, and then put in Glauber's salt, which can help melting, and put them into a clay-fired porcelain crucible for firing.

The firing temperature needs to be above 1500 degrees. The temperature of this pottery kiln is not much different. Let's see if it can work.

When the time is up, take out the porcelain crucible, the melt inside is a little cloudy and mixed with many bubbles, stir the bubbles to disperse, put it in again, continue firing for the same time, then take it out, then pour it out and let it cool naturally .

After cooling and forming, a palm-sized glass is obtained.

This glass has a faint yellow color, it is not as transparent and pure as the glass of the later generations, but it is much clearer than the bronze mirror, at least the figure reflected is clear and clear.

Xu Yinyin continued to try to adjust the ratio and experimented a few times, but the glass made was also light yellow, not pure white, presumably it should be a problem with the raw material, the raw material contained minerals, unlike later generations, most of them were made of Glass made from glass powder is naturally pure white and flawless.

But it has light yellow glass, and it is more distinctive, so it's not bad to look at it like this.

So be it!

Xu Yinyin personally made the best cosmetic set, and put it in a box carved with phoenixes specially made by craftsmen. The bronze mirror on the first floor of the box was replaced with this glass mirror.

Afterwards, the makeup box was sent to Guanshi Wu, and he was asked to help, presenting the makeup box as a birthday gift to the empress.

The cosmetic box, Wu Guanshi knows, at present, the cosmetic box in Xuji shop can't be bought for money, there is a fixed number every month, and you have to make a reservation if you want it.

He also knew that Mr. Jiacheng Township had been working for half a month in Du's pottery kiln outside the city.

In view of the heat pack that came from Jiacheng Township Lord before, Wu Guanshi did not think that Jiacheng Township Lord came in person, it was just a cosmetic box.

Of course, not everyone can send things to the palace. Of course, Guanshi Wu has to check the things that are to be given to the empress.

Therefore, when he opened the box, he saw the glass mirror first, and his face was reflected in the mirror. He clearly saw a finger-long scar on his left cheek, with a little black, which was The result of years of precipitation.

This thing can actually illuminate a person's face so clearly!It is no small matter!

As the emperor's confidant, Guanshi Wu immediately thought of a lot. After making this thing, it can send a steady stream of gold and silver to the emperor's private treasury.

Wu Guanshi was deeply shocked, and took a deep look at Xu Yinyin.

Xu Yinyin was calm and composed, and immediately took out the glass prescription and presented it, "This is a gift from Jiacheng to the emperor, please also pass it on to Guanshi Wu."

Wu Guanshi took it and unfolded it, and immediately looked solemn, and then he didn't dare to delay, and sent someone to carefully escort the box and the prescription to Beijing!
Heren, the official in charge of the mine.
