Transmigrated into a female county magistrate during a famine, leading her country to prosperity

Chapter 666: Haha, my hair is gone too!

It's also a bit funny to say.

In the absence of glass, they had to make glass using a blast furnace without glass as a window aid.

Logically this seems like a closed loop, like hatching a chicken without an egg.

But there are solutions. The most likely solution is to find a piece of sapphire that is large enough, transparent enough, and has stable enough internal crystals, so that it can be polished and used as a window material.

With such high requirements for a sapphire, Shen Zheng couldn't find it in a short period of time. Even if she really wanted to find it, she would have to have it in the Great Zhou Dynasty.

Since several methods didn't work, Shen Zheng could only choose the dumbest way, which was to open the furnace and look at the condition of the materials.

Liang Fu wanted to scold Wei Que, but when he looked at Shen Zheng's face, he was stunned, "Your eyebrows... uh, and your hair..."

Looking at his strange expression, Shen Zheng was suddenly stunned.

No way......

Her face was stiff, and she slowly raised her hand and touched her eyebrows.

The touch of charcoal... like the residue of burnt charcoal...

Shen Zheng's eyebrows twitched and she accidentally used too much force with her fingers, causing a small piece of black ash to fall from her eyebrows.

According to the curvature of her face, the black ash should have fallen on her eyelashes. After all, Shen Zheng still had some confidence in her long eyelashes. But what she didn't expect was that the black ash fell freely all the way and landed on her eyelids, cheeks, and nose, but not on her eyelashes.

A bad premonition spread in Shen Zheng's heart, and her fingers slowly moved downwards...

"My eyelashes are gone too!" The next moment, she screamed, with endless despair in her voice.

She looked at her fingers covered in black ash and murmured, "I have become... an immortal without eyelashes or eyebrows..."

When Liang Fu heard this, the words of comfort got stuck in his throat and he couldn't utter a single word.

Mr. Shen...

Are you crazy?!

Shen Zheng's expression twisted for a moment, then she remembered that Liang Fu had just said "hair", and quickly raised her hand to touch the hair on her forehead.

next moment--

"Haha! Gone too!"

She rubbed her palm on her forehead, and a large piece of black ash fell down, leaving black spots all over her face, which looked a little scary at first glance in the night.

Liang Fu swallowed silently and took two steps back.

"Um... Lord Shen, your hair and eyebrows will grow back... You don't have to worry, just give them some time."

Shen Zheng did not reply, but continued squatting on the ground hugging her knees.

Just as Liang Fu was about to open his mouth to continue comforting her, she suddenly jumped up and hit her head against Liang Fu's chin, causing him to cover his chin and step back repeatedly in pain.

"Hero!" Shen Zheng suddenly turned to look at him, pointing at her eyebrows and hair: "A hero will inevitably have scars on the road to success. I'm fine, I'll go find Qianzhi to prescribe some hair growth... uh, hair growth prescription the next day."

Eyebrows and eyelashes should be able to grow back in two or three months, but the hair on the forehead...

If I don't take some medicine, I'm afraid that my bangs will just grow out in two or three months, and it will be a bit lackluster to attend the Queen Mother's birthday party...

This sudden change startled Liang Fu so much that he looked her up and down for a long time.

"Are you... really okay?" he asked.

"It's just a minor problem." Shen Zheng waved her hand, the joke faded, and her expression became serious: "No experiment is smooth sailing. And it's also because I was too anxious and careless. It's just a little hair, not an eye, not skin, not life, it's already good enough. This is the punishment I deserve."

Just as Liang Fu said before, Liang Fu and Wei Que may not know how powerful the blast furnace is, but she knows it very well in her heart.

But she was still careless because of her anxiety and did not prepare protective equipment in advance, which led to the "tragedy".

For many things, one has to suffer before one can learn from them. This truth is eternal.

Liang Fu looked at her steadily, and then he realized that she was not crazy just now, but was using her own way to dispel the worries of this old man.

If Shen Zheng hadn't deliberately reacted to the stress by shouting, he would probably still be feeling endless self-blame and would have cursed Fang Qizheng a few times.

Liang Fu breathed a sigh of relief and looked at Shen Zheng with a more loving gaze.

Shen Zheng had a black face. She took a towel from the side, dipped it in water, wiped it on her face twice, and said business: "The white sand has been melted."

The "melt" she mentioned was not melting in the true sense, but the white sand turned red inside and out, which had met the prerequisite for the next step.

"Is it really melted?" Although Liang Fu had anticipated this result, the advantages of blast furnace calcination still made his heart skip a beat.

"Yes." Shen Zheng nodded firmly: "But the upper limit of the blast furnace is also limited. The next step is to add feldspar and limestone to help flux."

Pour the purified feldspar and limestone into the material inlet to lower the melting point of white sand, thus achieving true "melting".

This is a good start, but...

Liang Fu hesitated for a moment, but finally said, "For the next test, let's... do a blind test."

Without protective masks, they can only conduct blind tests for now, which means that they can no longer open the furnace mouth to check the condition of the raw materials. They can only estimate the actual melting time of the white sand after unloading the materials, and then continue to unload the materials.

During the entire calcination process, they have no idea about the condition of the charge and can only find out when the furnace is opened at the end.

If they fail, they won't even know at which step they failed.

But even if you fail, it is also experience.

Even if they cannot see the condition of the furnace charge, they can remember which time period is wrong for loading the charge and avoid it next time.

The sounds of night insects grew louder and louder, the bright moon gradually rose higher, and Shen Zheng and the other person returned to the blast furnace room.

At midnight, the whole Tongan County fell into silence. This was the best time for the people to sleep, but suddenly a muffled sound was heard from the blast furnace room of the printing house.

"Cough-cough-"

"Cough-cough-"

Two figures ran out of the blast furnace room one after the other, coughing as they ran.

"The furnace exploded." Liang Fu stood at the door and looked inside helplessly.

It is common for a furnace to explode when calcining items. For them, as long as the furnace does not collapse and people are not injured, everything else is a small matter.

Looking at the billowing black smoke overhead, Shen Zheng also sighed, "There are many reasons for the explosion, but we don't have the right means of detection, so we can only rely on reverse deduction... Let me think about which step is wrong."

Incorrect furnace temperature, raw material distribution, furnace structure, and operation methods may all lead to furnace explosion.

The two waited outside the door for a while, and after the smoke cleared, they went in to clean up the mess.
