Queen Mother's A Scientist

Hua Qingxue holds the glass in her hand and rubs it carefully.

The glass is spherical with a big round belly and a small opening only one circle larger than the copper coin on one side. The wall of the glass is uniform and transparent. You can see many bubbles in the inner layer. Although it is not compared with modern glass, it is much brighter than the two glassware brought by master song.

"How did you do it?" Hua Qingxue asked.

Su Shaowen was a little nervous and replied, "I... I added river sand..."

It was river sand.

Hua Qingxue immediately understood that the main component of river sand is quartz, and quartz is one of the main raw materials for making glass.

The reason why Hua Qingxue said it was a misunderstanding just now is that she remembered the glass composition wrong.

Although there was glass in ancient times, only some opaque lead barium glass could be made -- lead barium glass was bright and gorgeous. It was very popular for ornaments and jewelry. Such glass was fragile, not heat-resistant, not resistant to sudden cooling and heat. It could only be used as decorations and jewelry, not containers.

That's why Hua Qingxue kept telling master song that he couldn't do it.

It's not about skills, but about raw materials.

Hua Qingxue was disappointed. Unexpectedly, master song's little apprentice could think of making such a spherical glass with such a small opening.

The glass bottle made by master song has a small mouth, but if you look carefully, you will find that the bottleneck and the bottle body are two parts, which are bonded together after being done. The ball bottle made by Su Shaowen is a whole, which is very valuable.

Hua Qingxue asked him again, "how did you make your mouth so small?"

In ancient times, glass was made by melting and casting. There was no way to make such a small opening.

The melting and casting method is to grind various raw materials for making glass into powder, put them into the soil mold, melt and set the glass after high-temperature calcination, remove the mold after cooling, and then grind it all over.

This method is actually a method of processing bronzes. The cost is very high. The fineness of modeling depends on the fineness of the mold. Sometimes a glass handicraft needs to carve dozens of different molds and bond them one by one after demoulding, so it is impossible to make this effect of inner hollow core.

Su Shaowen didn't dare to hide, and carefully replied, "I made a glass ball first, put it in when the liquid glass cooled down, hang it with a metal wire, wait until the liquid glass solidifies completely, and then break the inner glass ball a little bit along the metal wire."

Hua Qingxue opened her eyes in surprise. She didn't expect Su Shaowen to use such a tricky method!

He put the glass ball into the liquid glass and squeezed out the shape of the glass. When the glass cools and solidifies, the glass ball inside can't be taken out! So he smashed the glass ball in the inner layer and removed the broken glass slag a little bit!

This is a great test of strength, angle and skill! Because a little carelessness will break the outer glass!

Hua Qingxue holds the glass and is lost in thought.

It is obviously impossible for glass craftsmen to directly make their own test tubes, beakers and distillation flasks.

Because what she needs is sodium calcium glass that can withstand high temperature, not lead barium glass with gorgeous colors.

Therefore, the first thing she has to solve is the problem of raw materials.

Secondly, the production process.

Melting and casting method is obviously undesirable. The best method to make containers is blowing method. This method does not need carving models. It has low cost and high output. It is a method widely used by Western glass craftsmen.

Hua Qingxue was fascinated. Su Shaowen stood aside, uneasy, but he didn't dare to disturb.

When Liang Wensheng came in, Hua Qingxue came back.

"Master, I've sent you away." Liang Wensheng smiled at Su Shaowen and asked, "how do you arrange these little brothers?"

Su Shaowen was named and his face turned red, as if he was very embarrassed.

Hua Qingxue thought about it, looked at Su Shaowen and said with a smile, "first live here and start work when the crucible kiln is ready."

Su Shaowen asked modestly: "... What do you need me to do?"

"Make glass." Hua Qingxue smiled, "but it will be a little different from your previous method. I have a new method here, but you need to figure it out and learn by yourself."

Liang Wensheng was stunned. "Master, aren't you going to teach him?"

"I can't teach." Hua Qingxue sighed helplessly, "I only know the method, but I won't."

It's like knowing how to ride a bike, but if you really ride a bike, you won't learn it without falling several times.

The glass blowing method is the same. Hua Qingxue knows the method and principle, but if she really lets her blow, she may not be better than Su Shaowen.

"I, I am willing to learn!" Su Shaowen said with a red face.

"I also learn!" Liang Wensheng quickly plugged in.

Hua Qingxue smiled. "You need to keep an eye on the firearm camp. It's best to finish it before autumn. When it's finished, we'll have to purify raw materials, improve zhentianlei, and make rockets, artillery and guns... We'll be very busy at that time."

Liang Wensheng grinned, his eyes full of longing.

Hua Qingxue handed Su Shaowen to Liang Wensheng, and then went to check the recent progress of the firearm camp. Looking at the shaped buildings, she was both looking forward to and somewhat disappointed.

All attempts will be a process from countless failures to success.

Although I have made countless psychological preparations, I still worry about failure

Today, she didn't see the glass she wanted. She was a little lost.

Because of her mistake, she forgot the difference between the two kinds of glass. Without much thought, she asked Fu tingye to inquire and invite someone for her. As a result, she was busy in vain.

Alas

Hua Qingxue can only hope on the little apprentice now. Since he has strong research ability, he hopes to master the glass blowing method as soon as possible

In fact, in Hua Qingxue's memory, a skilled glass blowing master can't practice in two or three years.

At the thought of this, huaqingxue is even more depressed.

Because she can't wait that long

……

The carriage rumbled forward, and the sun was still burning outside.

Hua Qingxue went out of the door and felt very sweaty, sticky and uncomfortable.

The mood is getting more and more bored.

Now she just wants to go home as soon as possible, take off this layer of sweaty clothes, and soak in cold water!

The leading bodyguard outside the carriage called Wu Zhuo and suddenly asked her, "Miss Hua, there is a fork in front. Do you want to go to the camp?"

Hua Qingxue was slightly stunned.

The bodyguard obviously wanted her to see the general.

In the past, Fu tingye would go back to the city every two or three days to see Hua Qingxue. In recent days, I don't know if the military affairs are busy. Hua Qingxue hasn't seen Fu tingye.

Hua Qingxue thought for a while. It's rare to come out. Let's go and have a look

——In love, there should be ups and downs. It's always bad. He always comes to see her, and she should go to see him occasionally.

Hua Qingxue's mouth could not help but tilt up and thought, will he be surprised when he suddenly goes to see him?

When the carriage arrives at Qingzhou camp, Hua Qingxue goes directly to Fu tingye's camp, but there is no one.

"Miss Hua, the general has gone to the school field." The soldiers outside the camp told her.

To the school yard? Isn't he afraid of prickly heat when he goes to the school field in this hot day?

Hua Qingxue went to the school yard again.

The military camp was very big. Hua Qingxue walked all the way and sweated all over again.

On the road, I passed a camp, surrounded by many soldiers dressed in different costumes. They don't look like soldiers of Daqi.

Hua Qingxue felt strange and couldn't help looking at it more.

"Who are those people?" She asked Wu Zhuo, the bodyguard beside her.

"They are soldiers of Nanzhao."

Even if she knew the answer, her doubts didn't diminish at all, because she didn't know where Nanzhao was

Approaching the school yard, I found that there were more soldiers in Nanzhao and stayed near the school yard with the soldiers of Daqi. These soldiers were like trees in the scorching sun.

Wooden frames are placed at the East and West ends of the school field, on which all kinds of weapons are displayed. In the center of the school field, a man and a woman are competing.

The man is tall and burly, obviously Fu tingye.

The woman was tall and exquisite. She was dressed in an alien dress, with yellow gold chips on her cuffs and waist. She reflected dazzling light with the change of action, which was very eye-catching.

Far away, Hua Qingxue can't see the woman's face clearly. Just by virtue of her hot figure, she feels like a gorgeous girl.

Hua Qingxue stood on the side and looked at it silently for a while.

Fu tingye's weapon was a long knife, while the woman's weapon was two full moon machetes. They practiced in the school field and made a metal sound of weapon collision from time to time.

Fu tingye cuts horizontally with a long knife. The woman's waist is as sensitive as a snake. She dodges in an instant! Throw out your machete at the same time!

Fu tingye flashed sideways. In the next moment, the handle of the knife hit the woman's wrist, and the machete in her right hand immediately came out——

Sometimes the soldiers on the side shouted loudly.

Hua Qingxue frowned.

She couldn't understand the moves of the two people's competition. She only roughly saw that Fu tingye had a slight advantage, but the woman was very resilient. The more urgent the attack was, the faster it was. Even if she was knocked down a knife, she didn't have the slightest intention of giving in.

Until the woman left a machete and was directly cut off by Fu tingye!

Her body fell weightless and heavily on the school field, splashing gray dust.

Fu tingye reaches out his hand to help her up, but she seems to be hurt. She stumbles and falls into Fu tingye's arms——

Fu tingye steadfastly held her waist and ran from outside the school yard. Two soldiers, one left and one right, took the woman from Fu tingye's arms.

"It's the princess of Nanzhao state. Her name is Wu Xinyao. It seems that she came to ask Daqi for help this time." Wu Zhuo said to Qingxue.

Hua Qingxue's eyes moved away from the big hand on Wu Xinyao's waist and slowly nodded his head, "Oh."

She turned and left.

Wu Zhuo followed her and asked, "Miss Hua, don't you go to see the general?"

"Hey?" Hua Qingxue said hesitantly, "didn't you say that the princess of Nanzhao came to ask for help? Since the general has something to do... I'll come back next time. If I go now, I'll make trouble for him. "

Wu Zhuo was sent by Fu tingye to protect Hua Qingxue's safety. After thinking about it, he felt that Hua Qingxue was now like a secret weapon of a general. It was really not suitable to be casually exposed to outsiders. He had no opinion at the moment.

Wu Zhuo and other bodyguards sent Hua Qingxue back to the carriage and returned to Panshui.

Hua Qingxue sat alone in the carriage, holding a handkerchief in his hand and wiping the sweat on his face.

She felt stuffy and hot, and her mood was inexplicably irritable. From time to time, she remembered Nanzhao Princess Luo Lu's soft waist, her slender arm wearing a gem armband, and the gold shining brightly. Fu tingye's palm brushed over the honey skin

She pursed her lips and felt even worse
