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

In front of Shen Zheng, Liang Fu is her elder and has a higher official rank than her.

But when it came to calcining colored glaze, he didn't dare to make any decision at all.

Not only had he never seen "Liuli", if Shen Zheng hadn't been there, he wouldn't even know what Liuli was, so how could he be in charge of calcining Liuli?

Therefore, Liang Fu had to follow Shen Zheng and ask for Shen Zheng's opinion on most matters during the forging process.

Even though he felt that it would be difficult to melt the white sand in an hour, the reason he could get to this point was not only because of his talent in manufacturing, but most importantly, he was never arrogant.

Since Shen Zheng said it is feasible, let's start the furnace and try it out. If it doesn't work, the two of them can discuss and experiment again!

It is better to have someone who takes the lead and makes decisions than two people who are both weak and have no opinions of their own.

The two of them entered the blast furnace room together, and the heat that hit them could no longer be called "heat" but "scalding".

Even the air was scalding hot.

Liang Fu adjusted his breathing, a hint of surprise flashed in his eyes, and he looked around, "Sir Shen, I can feel that the temperature in the furnace has reached an unprecedented level. Even the furnace in the Ministry of Industry is inferior to this..."

At this rate, one hour might be enough!

He looked towards the blast furnace, his eyes shining brightly.

If this precious furnace is only used to calcine colored glaze, it would be a waste of resources! If the Ministry of Industry had this furnace...

As Liang Fu's thoughts gradually drifted away, Shen Zheng had already picked up the charcoal tongs.

"Master Liang, the charcoal fire cannot be small, and it must not be extinguished, so... after opening the furnace, we must seize the time and see it clearly at one glance, and never take a second look."

One of the reasons is the fear that cold air will enter the furnace and affect the raw materials.

The second reason, and the most important one, is that even though the inner furnace wall has a heat-insulating layer, the temperature outside the furnace is extremely hot, indicating that the hot air in the furnace has been continuously compressed and has reached an extremely terrifying level.

Therefore, as soon as the furnace mouth is opened, the impact of the bursting hot air will definitely be huge, and the person checking it will get injured if he is not careful.

Ultra-high temperature burns are a very scary thing, and people who check the condition of the raw materials also have to bear a lot of psychological and physical pressure.

Shen Zheng handed the charcoal clamp to Liang Fu, "You open the furnace, I'll come and see, if I say close the furnace, you close it."

Liang Fu frowned and looked at Shen Zheng, "I see, I have long been accustomed to this kind of hot environment, and my body's reaction will be smaller than yours, so it is best for you to open and close the furnace."

"No." Shen Zheng said firmly, "I am young, have a good foundation, and react quickly. If there is an emergency, I can respond in time."

This was their first time using a blast furnace and their first time calcining white sand, so it was difficult to predict possible emergencies.

This was an attempt and also a valuable experience - Shen Zheng didn't believe that he could burn glass in one go. After all, the industrial ministries of various countries were not there to do it for free.

They have to assume the worst, which is that if someone is really injured, that person must be a young person with quick reaction and recovery.

If she and Liang Fu stood there, no one would say that Liang Fu was younger, right?

"This..." Liang Fu was about to argue, but Shen Zheng had already stuffed the charcoal clamp into his hand.

"Master Liang, it's almost time, let's not delay." After saying that, Shen Zheng brought a stone bench from outside to stand on, looked at the furnace mouth, took a deep breath and said, "It's time to open it."

Liang Fu gritted his teeth, a trace of struggle flashed in his eyes, but Shen Zheng had already stood next to the furnace. The longer he hesitated, the longer Shen Zheng would be burned by the high temperature.

He had no choice but to nod to Shen Zheng, raised his hand to press open the furnace mouth protection bolt with one hand, raised the charcoal clamp with the other hand, and hooked the furnace mouth cover open with force.

"boom--"

Shen Zheng had already slightly turned sideways, trying to avoid the initial impact of the heat wave, but the remaining heat wave was enough to make her drink a pot of water. A large mass of scorching hot air enveloped her upper body, making it difficult for her to breathe and she could only hold her breath.

Headache in the forehead, cheeks, chin, and nose.

This pain was no longer like the pain of being baked by hot air, but it was as if she was in a sea of ​​fire, and the spreading flames were licking her cheeks, trying to melt her there.

There is not much time left, and I can’t close my eyes!

Shen Zheng's will was fighting against her body. She wanted to open her eyes, but the burning sensation from her eyelids was controlling her body, constantly telling her not to open her eyes.

She insisted on opening her eyes!

Even Shen Zheng didn't know how she overcame her body's fear of the flames and how she suddenly opened her eyes and saw the scene inside the furnace at a glance.

"It can be closed now!" Shen Zheng's face flushed, veins popped out on his forehead, and after he shouted, he bent down and jumped off the stone bench.

Liang Fu immediately closed the furnace, pulled the safety bolt, grabbed Shen Zheng's sleeve and rushed out of the room.

Shen Zheng was stunned and resisted for a moment before running out with Liang Fu.

Fresh air rushed in, and Shen Zheng could no longer hold on. She squatted down with her knees hugged, gasping for breath, and a "ho ho" sound like a broken bellows kept coming out of her throat.

She was very sure that from the time she stepped onto the stone bench to the time she was pulled out of the blast furnace room by Liang Fu, it was probably less than a minute, let alone several minutes.

But at this moment, her body felt as if it had been burned for a whole day and night.

Liang Fu only knew that the temperature in the furnace was very high at this time, reaching an extremely terrifying level, but Shen Zheng knew in her heart that the temperature in the furnace had reached a thousand degrees. Although she avoided the initial high temperature shock, the aftermath should not be underestimated.

Shen Zheng was still squatting on the ground gasping for breath. Liang Fu clenched his fists beside her and suddenly started scolding Fang Qizhen.

"Fang Qizheng clearly knew that checking the furnace charge was extremely dangerous, but he didn't even bother to send us two heat-insulating hoods! You even gave him the method of purifying iron ore, and you're going to teach him how to forge steel in the future! Is his heart made of stone?"

Shen Zheng suddenly laughed when she heard that, panting, and looked up at Liang Fu.

The old man felt sorry for her and was upset, but had no place to vent his anger, so he could only direct his anger at Liang Fu.

"Laugh!" Liang Fu looked down at her, his eyes red. "I could feel how dangerous it was just now even from behind. This furnace is much more powerful than the kiln and the ground furnace! If I had known this earlier, I would never have agreed to let you check the furnace materials!"

Shen Zheng's breathing gradually became steady, and she said with a smile, "I can't let you watch this either. But the impact of opening the furnace was beyond my expectations... and Lord Fang probably doesn't know either, so we'll open the furnace midway to check."

Fang Qizhen had never seen the process of calcining glass, so he just forged the blast furnace according to the requirements and that was it.

If it is a standard blast furnace, in addition to the furnace mouth, material mouth, slag discharge port and other openings, a visual window will also be designed. The purpose is to observe the condition of the furnace charge to avoid the high temperature shock of opening the furnace mouth, and the calcination personnel can also be safer.

But their blast furnace was built in a hurry, and the materials for the visual window were not available in the Salt and Iron Bureau, let alone the Ministry of Industry.

Because the window forging material is the purpose of their calcination this time - high melting point quartz glass.
