There is another question that lingers in Mr. Bai's heart.

The slight relationship between Liuli and alchemy and sword casting, she has been managing books for her master in the palace for many years, and she doesn't know much. And this second grandmother grew up in the mountains and wilderness, and she was illiterate before, how did she know?

Xia Yanqing is nominally her student, but her identity is there, after all, she is the daughter of an official's family, whether it is her mother's family or her husband's family, she should not be underestimated, and she cannot be questioned too rudely.

It's just that in front of Xia Yanqing, there are slowly doubts.

Xia Yanqing didn't ask her what she was suspicious of, but only said the words she had thought of a long time ago: "When I was in the countryside, I went out to fetch water one day, and met two Taoist priests from the swimming side by the well, and they were chatting while filling the water bladder. I heard one of them say that when their master's alchemy is baked, if the temperature is still high, there will be liquid things flowing out, condensing into glass, which can be exchanged for some silver coins. ”

In the remote mountains and wilderness, the Taoist priests of the traveling party passed by by by accidentally, listening to them chatting for a leisurely day, and no one could verify the authenticity of this set of statements.

Moreover, the explanation given by Xia Yanqing is very reasonable. As long as the temperature of the Dan furnace is high enough, the lead and mercury material in the Dan medicine and the silica sand contained in the tandoor will naturally be in a molten state of the glass after the two compartments are in contact and dissolved.

The half-belief in Mr. Bai's eyes changed, and gradually, the believing component took over.

Xia Yanqing struck while the iron was hot and pulled over a piece of white paper.

The two girls have been listening to the side, and while Xia Yanqing persuaded Mr. Bai, it also played a role in them.

Xinxiu had long been convinced, and when she saw that Xia Yanqing was going to write, she hurriedly sent the prepared carbon strips.

For convenience and to avoid the trouble of grinding ink, the general sketches and the random graffiti of searching for memories, Xia Yanqing uses carbon strips, and the girl of Qiuyueyuan has long been familiar with her style.

"Sir, that's what I think......" Xia Yanqing took out the carbon strips, and while drawing, she explained to Mr. Bai and explained her plan.

The crucible, the stove made of refractory bricks that can be closed, and the materials that need to be added to the crucible, as well as auxiliary items such as paraffin, gypsum, iron tongs, etc., as well as the expected production process, Xia Yanqing explained to Mr. Bai one by one.

Of course, modern production does not have these things, which are all transformed and simplified by Xia Yanqing. Rao was like this, and he was still stunned when he heard Mr. Bai and the two maids present.

Mr. Bai was puzzled in his heart, is this woman still a country woman?

If the women in the countryside are so shrewd and capable, they can draw inferences from one another, and explain a profession that they have never seen so clearly. Are they, the women and even men who study in the bustling capital, embarrassed to come out to meet people and show off their superiority?

The two girls couldn't get back to it. The second grandmother just looked at the hairpin of the little lady of the Tao family, and heard that the grandfather of the little lady of the Tao family was a Taoist priest, and asked the companion room in the outer courtyard to find some books to read, and she could say that the head of making glass is the Tao.

The second grandmother's ability is very great.

After the explanation, Xia Yanqing added: "Sir, I don't want my in-laws' family to know about this, but this thing was done in my family's back house after all." In order to avoid accidentally breaking people and causing trouble to Mr., we can burn some small pottery as an excuse. ”

Mr. Bai nodded a little ignorantly, this second grandmother's brain turned fast enough, she had to think about what she said before.

According to the method dictated by Xia Er's grandmother, it is bound to start a fire in the backyard of the Wang family. After a long time, it is inevitable that people will look at it.

Firing pottery is a good way to cover up.

Although this dynasty is not very fashionable to do this, but in the previous dynasty, some Confucians and students took pottery as a pastime to cultivate sentiment.

The question is, how is it possible for the second grandmother to melt the sand and stone with the crucible of tinsmiths and blacksmiths to smelt the metal? It's a stone, and even if it's small, it's a true stone.

Faced with Mr. Bai's question, Xia Yanqing smiled sheepishly: "Well, Mr. Bai doesn't have to worry, as long as the temperature is high enough, how can there be something that can't be burned." If you don't try it, how do you know if it works? ”

It's just a temperature of nearly 2,000 degrees, and she plans to add soil alkali or soda to it, which will greatly reduce the smelting temperature of quartz sand.

Thinking of these details, thinking of the glazed products admired by the ancients, and the large amount of silver brought by the glazed products, Xia Yanqing almost immediately set up a stove to melt glass.

As long as she is sure that her idea is feasible, and then she can experiment with the recipes of various colors of glass and the melting effect of quartz deposits in various places, she can start to build a workshop and make a lot of money.

Her smile is not as dignified as everyone's daughters, and even a little skinny, but it is very reassuring.

Mr. Bai's heart settled down inexplicably. The second grandmother is a smart woman she has never seen before, and she speaks and acts properly and sophisticatedly. Not only can she explain the process of trial production of glass clearly and reasonably, but she can also show such a smile, does that mean that at least in the second grandmother's heart, this matter is indeed very certain.

Before Mr. Bai made up his mind, he asked Xia Yanqing again: "I have something that I need to confirm with Grandma Xia first." ”

"You say." Xia Yan Qingdao.

Mr. Bai has a lot of questions. But there is no way, there is a request for people like this, who let a temporary nurturing grandmother, she is facing a dilemma.

Fortunately, the mountains are high and the rivers are long, and there are times when she raises her eyebrows and impresses this Mr. Bai.

"If the second grandmother has full confidence in making glass, this is a great thing for a family. Leaving this business to the dowry shopkeeper and giving your house a certain percentage of the income not only does not need to be hidden, but also can consolidate the status of the second grandmother in the in-law's family. Why did the second grandmother hide this from her in-laws? Mr. Bai asked.

Judging from the current situation, the second wife of the Wang family is obviously separated from her in-laws. She has to have a spectrum in her heart, at least to make sure that Xia Yanqing is not antagonistic to the Wang family, and even harmful to the Wang family.

Although she hopes that her condition in her later years will become better and more secure, she must not do anything for the sake of the tiger.

Let's talk about this article for a little time today.

In fact, the previous setting of this article is just a story of a female protagonist traveling through ancient times, going directly into the cave room, and then struggling out of the back house, complementing the male protagonist.

In other words, the beginning of this article is not the type of business farming. However, after the article was published, the main tone of the article was changed due to various reasons. In fact, really speaking, this opening chapter is not quite in line with the opening of the type of farming and business.

(The author's words continue in Ha, I can't write below, so I take up a little space here.) ）
