After the exile, the Goddess of War became a group favorite

Chapter 170 Making Glass

Everyone in the Lu family got up very early, Lu Anran and the boys were the first ones, and the girls were about half an hour late.

Therefore, when the cock crowed, they got up to wash up and went to the school grounds. At this time, it was only seven o'clock in the morning, and the Lu family's school grounds were full of people.

None of the brothers from the Lu family started the special training in the morning with a team of [-] people, even the dwarves.

Lu Anran stood on the school platform and watched their training situation, planning in his mind what deficiencies could be improved.

After watching the training in the school field, Lu Anran went to the craftsman's workshop.

Just as he walked in, he saw Feng Guanglin walking out leisurely with a jar of wine, humming a strange tune. His posture was obviously ready to go out to play.

Lu Anran frowned suddenly: "Where are you going?"

"Of course I'm going to step on it..." Before Qing Zi could say anything, he saw Lu Anran, and Feng Guanglin immediately choked in his throat, with a bitter melon expression on his face:
"City Master Lu, you old man is not going to take out the paper now. I finally got some free time, so naturally I have to go out to meet friends, this...you won't let me go?" He said, reaching out his hand He touched it in his arms, and finally found a piece of candy.

Before handing it out, the corner of Lu Anran's mouth twitched: "Go back, I have something to tell you."

"Is there anything we can't talk about now?" Feng Guanglin was confused, and wanted to pass the candy to her. He really wanted to go out and play.

Lu Anran glanced at him, "I found a diatom material that can be used to refine glass."

As soon as these words came out, Feng Guanglin immediately became serious, and quickly put away the candy and put it back in his arms.In fact, not only Lu Anran, he also always wanted to build a greenhouse to ensure that vegetables can be grown in winter.

Although a large-scale vegetable greenhouse has been developed now, the output in the greenhouse will still decrease in winter, and he has to eat meat and pickled vegetables almost all winter, so he is very concerned about this matter. Heart.

"How?" he asked.

Lu Anran stepped over him, and said as he walked: "Through a lot of experiments, I tried a simple glass making process, which is to fuse silicon dioxide and some raw materials together and burn them, and dissolve them under high temperature. It's glass."

She found that quartzite, diatoms, soda ash, and thenardite in this world are very easy to obtain, while nitrate is even easier to obtain, and can be obtained directly from the remaining slag after iron smelting.

Limestone, feldspar, soda ash, boric acid, lead compound, barium compound, and sodium oxide can reduce the viscosity in glass formation, make glass easy to melt, and play a good role in fluxing.

Barium oxide plays an essential role with sodium oxide in the formation of glass; tin oxide can increase the chemical stability and mechanical strength of the glass.

Lead oxide can increase the density, improve the snaking, and have a special luster.Lead can make the glass have a large refractive index for light and a small scattering rate, making the glass more shiny and stable.

Limestone, feldspar, and soda ash are all relatively easy to obtain.

In the production process, we must also pay attention to the transparency of its color, so there must be a decolorizer. If you need an opaque effect, you need an emulsion reagent. To obtain glass of different colors, you must also add some other elements, such as iron. The glass takes on a variety of different winks.

Listening to Lu Anran's explanation, Feng Guanglin was at a loss, what quartz stone, soda ash, Glauber's salt?Why can't he understand a word?

Lu Anran was still talking about it, she was going to do the glass making by herself, recruiting many apprentices to study glass making with her.

It is very difficult to deduce the whole process from a simple process and method, each step must go through a lot of experiments, and it will take a lot of time just to produce glass.

Most of the silicides that come out are unqualified products, and it is difficult to meet Lu Anran's requirements.

Including the detailed design of the entire melting furnace, the inner tank needs to be all-metal grinding to obtain a smooth surface, and the inner tank must be kept from being corroded and softened at high temperature, and at the same time, it must not produce chemical reactions with the molten material.

People in this world don't even know what chemical changes are, and Lu Anran has to use his own efforts to deduce every process continuously.

Since she had studied the identification of metals for a period of time in the last days, it can be said that she is quite experienced, so she was able to obtain the required elements through the identification of minerals.

The formulas in many chemistry books are very simple, but it is not easy at all in the process of operating in the world. Lu Anran still has to go through a lot of experiments to master some of the relevant skills.

There are no search engines such as Baidu and Google in this world, and these new affairs are all started from scratch, so Lu Anran must spend a lot of time on research.

Feng Guanglin asked himself if he had a relative understanding of Gewu, but he didn't understand anything specific.

Especially the glass that Lu Anran was going to make, he was very curious.

He felt that Lu Anran was quite like a legendary god, a god who specialized in inventions and creations.

He had no idea what Lu Anran was going to do.

"Iron Fist will make the furnace according to my requirements. Your task is to make glass. If you don't understand anything about chemistry, you can ask Bian Ya. If you don't understand, just write it down. I will come and explain it to you when I have time." .”

After listening to her words, Feng Guanglin was stunned to death, his face was full of where am I?What have I heard?What did City Lord Lu say?

"Well, Bian Ya has important tasks to do, so you should disturb her as little as possible. Her tasks are no easier than yours."

"No, Lord Lu." Feng Guanglin reacted with a ghostly expression on his face: "I don't know anything about chemistry, and if you still don't let me ask her, what should I do?"

Lu Anran glanced at him, then took out a handwritten simplified chemistry book and handed it to him: "It records how these materials are refined, you just need to follow the instructions in the book, and you will be able to Success. If you have any questions, just write it down and come to me."

Feng Guanglin looked at the book in his hand, then at Lu Anran, the corner of his mouth twitched, did City Lord Lu use him as an animal?No time to take a bath?

"What's your expression?" Seeing him looking at him with resentment, Lu Anran couldn't help but rolled his eyes, "I've made the glass, I'll give you a month's rest."

"Really?" Feng Guanglin's eyes lit up, "City Lord Lu keeps his word!"

"Naturally." Lu Anran nodded, the glass in her space was already used up, otherwise she wouldn't be so eager to force Feng Guanglin to make glass.

Not only glass, but many things are rapidly decreasing, which has to make her open source and constantly look for raw materials that can be manufactured, such as salt.
