For Wang Sheng and Goudan Erya, this is a completely unfamiliar field, but because of Lin Meiyi's guidance, the research on limestone is going quite smoothly.

First of all, limestone is calcined at high temperature, and there is coal in Yangxian County, which creates conditions for high temperature, and the calcination process is quite smooth.

The material is obtained, followed by the ratio study of other cement ingredients.

Because Lin Meiyi only had theoretical knowledge and no practical experience, the four of them worked hard to finalize the final ratio.

70% limestone, 10% clay, 1% iron, 9% coal.

After getting the formula and experimenting immediately, when he saw a piece of condensed cement brick, Wang Sheng was so excited that he almost cried.

He felt that his life's pursuit was nothing more than that.

"It's so soft, how can it be so hard?" Erya asked.

Lin Meiyi's knowledge is limited, and she still doesn't know how to explain this change to everyone, so she fooled around the past, and a bold idea immediately rose in her mind.

Since the cement can be made, is it possible to make the glass too?

After all, with cement experience in the past, glass shouldn't be difficult, right?

They already have the high temperature conditions and some of the raw materials, so why not give it a try?

As soon as the idea came out, it was difficult to suppress it, Lin Meiyi looked up at the three people in front of her, and asked tentatively:

"Do you know what glass is made of?"

"Glass?" The three of them looked up at her in unison, "You know? ”

Lin Meiyi raised her eyebrows, "Maybe, probably, maybe I know." ”

"It's really fake!" Wang Sheng asked excitedly, looked at Lin Meiyi nervously, and subconsciously held her breath, for fear of missing any word she said.

Lin Meiyi nodded, and shook her head again, "I only know the general procedure, the specific details are not clear, we need to study it ourselves." ”

"Wow, eldest sister, you even know how to make glass? If we really make glass, wouldn't our family have to make a fortune? Dogdan's eyes widened in shock, and he couldn't imagine what a huge fortune it would be if he succeeded.

You must know that the smallest and smallest glass products on the market can also be sold for fifty taels.

Not to mention anything else, the few glass lamps with average transparency that his second sister Fei wanted to buy would be two hundred taels smaller, if they made thousands of lamps......

"Mother!" Dogan was frightened by his own bold idea.

Wang Sheng took a deep breath and let Lin Meiyi say directly, even if he was tired to death in the laboratory, he must get the glass out.

Not for money, but for ideals!

"First of all, we need baking soda, that is, soda ash, adding soda ash can reduce the melting point of the raw material of glass to our current controllable range, the raw material of this thing can be limestone, salt, and water, which is the simplest step."

"However, it is not easy to raise the temperature, we have to make two more bellows, and our high-temperature furnace has to be reinforced."

Lin Meiyi spread her hands, "These are just preparations, the real difficulty is in the acquisition of raw materials, we have to find silicon." ”

"Turtle? Looking for a turtle? Erya asked innocently.

When the words came out, he felt a little wrong, his little brows furrowed, and his face was entangled, "No, the turtle is not like glass at all." ”

Lin Meiyi didn't roll her eyes, "This silicon is not the other turtle!" Just come with me! ”

The three of them nodded dumbfounded, "Oh, good." ”

So, Qing Lan, who was in charge of supervising the canal opening by the river, suddenly found that she had frequently seen Lin Meiyi and others by the river in the past few days, sneaky looks, and she didn't know what bad things she thought they were doing.

Once or twice, Qinglan regarded it as an accident and didn't care much about it, after all, there are many people who come to the river every day to fetch water, in case Lin Meiyi is here to experience life, it is understandable.

But for five days in a row, Lin Meiyi's figure could still be seen appearing by the river, and Qinglan's intuition told him that this was definitely not an accident!

"Hey! What are you doing here? ”

Er Ya and Goudan were carrying a cloth bag and shoveling sand and gravel inside, when they suddenly heard a scolding from behind, the two of them trembled with fright, and hurriedly turned their heads to look behind them, and when they saw Qinglan wearing a military uniform, the two of them suddenly rolled their eyes angrily.

Erya dropped the shovel and replied confidently: "Shovel sand, what's wrong?" Is it possible that the sand by the river is still your home? ”

"That's it, other people are also picking up stones by the river, why didn't I see you talking about them." Dogan echoed.

The sister and brother sang and harmonized, Qinglan still thought that she was a big villain, so she glared at the two sisters and brothers helplessly, stepped forward to pull the cloth bag in the dog's hand, and saw that it was really full of sand, and the fox asked:

"I've seen you for five days in a row, what are you shoveling so much sand for?"

The dog Dan closed the cloth bag and glared: "I want you to take care of it!" ”

Forget it that time before, this time I don't take him in my eyes like this, it's unbearable!

Qing Lan patted the big knife on her waist, "This official asked you, what do you want to get so much sand?" ”

As soon as the official frame was taken out, the momentum of the two small ones weakened significantly.

Qing Lan saw that the two were about to speak, and was about to smile proudly, but before she thought about it, the woman's smiling voice suddenly came from behind, and the cold air blew directly on his neck, and the whole person was stiff.

"Lord Qing is so powerful, you even have to dig some sand, don't you have anything else to do?"

Lin Meiyi walked out from behind Qing Lan, carrying a large shovel with special characteristics in her hand, the sharp blade flashed with silver cold, Qing Lan had no doubt that if this shovel came down, she would die.

"Ahem!" Qinglan coughed twice, and quietly took two steps back, pulling away the distance.

At the same time, I couldn't help but complain in my heart about Lin Meiyi's generosity, other people's families were reluctant to make iron pots, but she had so much money that she had nowhere to spend, so she actually got such a luxurious big shovel.

That weight, ordinary people are afraid that they can't move, she is a girl's house easily, what a pervert!

"Lin Meiyi, what are you digging so much sand?" Qinglan asked forcefully.

Lin Meiyi raised her eyebrows, stood in front of her younger siblings, and said with a smile: "Play." ”

"What? Can't play with some sand anymore? We didn't get in the way of you soldiers, Lord Qing, are you a little lenient? ”

When Qinglan heard this, she looked at Lin Meiyi's arrogant expression again, and muttered secretly, "Lord Ben still doesn't believe that no one can't take care of you", and left in disgrace.

Seeing him go away, Lin Meiyi snorted lightly and continued to dig sand with her younger siblings.

As a result, that night, the research room was raided by Lin Dalang.

"Qinglan said that you go to the river to dig sand every day, what are you doing sneakily!"

"I said eldest sister, you are really, you are not at home all day, what are you doing in this broken house?"

Lin Dalang pushed open the closed high-temperature room while chattering, and walked in with a step.
