Qi Lele has consulted a lot of information on the production method of glass before, so it is good to summarize it at this time.

In this era, if you want to fire glass, you can only use a kiln that fires glass.

The two are essentially the same kind of substances, but the raw materials and manufacturing processes are different.

Compared with glass, the melting point of glass is higher, and the clay kiln cannot reach this temperature, so it is necessary to add additives to reduce the melting point.

mentioned the field he was good at, and the expressions of the father and son of the Qiu family suddenly changed.

"What are additives?"

"Potassium carbonate, which can be extracted from plant ash."

"How do I withdraw it?"

Xie Zi'an said: "Soak the plant ashes in cold water, then filter the fine residue with gauze, and boil the remaining water to get potassium carbonate."

Qiu Li asked again, "If you add this potassium carbonate, you can burn the sand into glass water?"

"Yes, it's just that you still need to figure out how much to add."

"And what about after the glass of water is burned?"

"Use a hollow copper pipe dipped in glass water, blow it, and polish it."

The father and son of the Qiu family suddenly gathered together and discussed in a low voice.

Xie Zi'an is not surprised, Jing Yan Jingyue is often like this, he said, "You guys think about it first, but you can give me an answer tomorrow."

Qiu Feng came back to his senses and hurriedly said, "Big Prince! We're willing to burn glass!"

Xie Zi'an looked at the other two.

Qiu Shi and Qiu Li expressed their attitudes one after another: "We are also willing."

Xie Zi'an bowed: "To fire glass, you need to build a kiln, and you will be responsible for selecting and supervising the construction of the kiln."

"This, this is probably ......."

"You are experts, so you can only mention what you need, and you don't have to worry about others." Xie Zi'an said slowly, "I just want the result."

Qiu Feng's heart trembled, and he didn't dare to speak for a while.

"Our contract is for two years, and if it is two years, and you can't make it, or you don't make any progress, I'll invite someone else."

At this point, Qiu Feng was still a little hesitant, but when he saw Qiu Li take a step forward, he arched his hand: "I will not disgrace my life!"

Xie Zi'an looked at him: "If it can be done, the dividends of the glass sold in the future will be given to you in 10%."

As soon as these words came out, all three of them were shocked.

"The Xie family does not raise useless people, but it will not treat meritorious people badly. Those who are able work more, and they get more for their work."

Qi Lele looked at the three of the father and son of the Qiu family with a look of chicken blood that they were determined to get, and looked at Xie Zi'an with admiration.

Xie Da Flicker, Zi'an retired.

"It's going to take a few days to pick this cocoon, so why don't we go out and walk around?"

Mu Shiwan has been coming to Xie's house for five or six days, and she is either working or watching the silkworm cocoon, so that Qi Lele is so angry that she can't go, and she has to pull people out and go around today.

"I'll listen to my sister's arrangement."

Qi Lele smiled: "I promised to take you to go fishing before, and the weather is just right today, why don't we go fishing?"

"Good!"

Qi Lele turned his head to find Xie Zi'an: "Just go to the place you took me to last time!"

Xie Zi'an pretended not to know: "Which place?"

"That's where you lost a goldfish hook!" Qi Lele said with a threat: "If you pretend to be stupid again, I will melt all your fish hooks!"

Xie Zi'an smiled and said, "I was wrong! Madame, don't blame! No wonder!"

Not far away, Mu Shiwan was amazed.

Although she didn't see Xie Zi'an much, she always felt that he was elegant and detached, as if he was far away from the fireworks of the world, when had she ever seen him like this? actually made her vaguely see a little bit of Xie Ziyan's shadow!

Taking advantage of the preparation of things, Qi Lele went to invite Xie Dai and Su Yaxian again.

Xie Dai went out early in the morning, and Su Yaxian politely refused: "Your father has been busy with private school recently, I have recently obtained a few music scores, I want to refer to one or two, you can go."

Qi Le

Only then did Le know that Su Yaxian could also play the piano!

"Not only mother, but also me."

Qi Lele looked at Xie Zi'an faintly: "I'm a happy blind person at home?"

"If Madame wants to learn, I'll teach Madame that."

Qi Lele shook his head decisively, the ancients played the guqin.

One word, difficult!

In fact, when I think about it, it's not surprising, Su Yaxian looks like a young lady raised by a big family, and the piano, chess, calligraphy and painting should be all the same, but why don't you see her playing?

"On the way to Shangxi Village before, my mother's piano broke, and my father was afraid that she would be sad, so he sealed all the pianos at home."

"Won't you play this in the future?"

"Not really, wait for my mother's piano to be ready."

The Xie family has moved to Shangxi Village for two years, right? It's been two years, and it hasn't been done yet?

"Daddy's piano took eight years to make."

Qi Lele: "......"

Well, she knew she was lonely again.

The capital, Mu Province.

Fan Shuo didn't see Mu Junkun come to him for a few days, but he thought that he had provoked him somewhere, so he specially brought a gift and came to the door to make amends.

He was a frequent visitor to the house, so he didn't need people to lead the way, so he went straight to Mu Junkun's yard and saw him working there with a hoe.

"Junkun, what are you doing here?"

Mu Junkun didn't raise his head: "Farming!"

Fan Shuo's white and chubby little face was very dazed: "Do you plant flowers?"

"Grow vegetables!"

Fan Shuo: "......"

Is his friend angry? Still not angry?

Mu Junkun finished a round of soil, threw the hoe, and wiped the sweat beads from his face: "It's all thanks to my good sister!"

"Sister Mu?"

"Who else but her!"

Mu Junkun said angrily: "What to say, the children of the Xie family have to work every day, raising silkworms, going to the ground, and building houses, so they have such good martial arts!" And because of the hardships, I know that it is not easy to read! Therefore they are also learned!"

"When my father and mother heard this, they thought it made sense, so they ordered someone to pluck my garden and let me grow vegetables that day!"

Fan Shuo: "......"

"You be quiet, just talk to me about this, it's not good to spread it! No one else knows where Sister Mu has gone!"

Mu Junkun was shocked to realize that he had said the wrong thing, and hurriedly ran out to look left and right, and saw that there was no one around, so he went back to the courtyard, hooked Fan Shuo's neck, and lowered his voice and said, "You have to suffocate to death in your heart about this!" I can't mention it anywhere!"

Fan Shuo nodded again and again: "Don't mention it, don't mention it!" Don't even mention my dad! No one mentioned it!"

Mu Junkun let go of his hand at this time, he still believes in Fan Shuo's character, although he looks white and fat, bullying and unreliable, but he is used to saying a word, which is much better than the two boys in the Tan family!

Fan Shuo persuaded, "That's also for your good."

"What! What good work can be done by digging in the earth? Why don't I practice the boxing technique!"

The more Mu Junkun thought about it, the more angry he became: "It's a shame that I'm so good to her, and I'm going to send her Feiyun over even if I'm scolded!"

Fan Shuo said, "However, every time Uncle Mu asked you to practice martial arts in the past, you always wanted to be lazy, but today you take the initiative to think about practicing martial arts!"

Mu Junkun was stunned for a moment, but he heard that the little fat man stabbed him in the heart again.

"It can be seen that this method is indeed effective!"
