Li Xiaolan listened to the screams getting closer and closer outside the hospital, her eyes became more solemn: "Mom, it's the Beidi Rangers. I'm afraid they are coming directly to you and me."
Qin Cheng nodded, but his expression was not at all nervous. On the contrary, the arrival of the Beidi Rangers seemed to be expected.
While letting Li Xiaolan pack her things, she wrote lightly: "The battle between Daliang and Beidi is imminent. Beidi spies are all over Daliang, and they must have found out the truth. Now they come to rob you and my mother, and they must be taking hostages as threats. , disturbing your father's mind. Even if your father's righteousness is unwavering, it is impossible for the saint to take the risk and continue to hand over the command of the Beidi war to your father."
"Beidi's move is a huge blow to the bottom of the pot. It's unexpected, but it's reasonable!"
"Lan'er, don't panic. The Beidi Rangers can go deep into Beixi County. There must not be many people coming. They can just escape with their mother."
While talking, Qin Cheng and Li Xiaolan shouldered their burdens, opened the back window, and climbed out one after another through the narrow window.
He hid under the low wall, walked around the path, and soon arrived at the edge of the village.
Ahead is a deserted forest.
Just as he was about to escape, he heard the sound of rapid horse hooves in his ears.
A war horse lying in ambush outside the village had spotted the mother and daughter, and galloped over. The horse in his hand pointed in front of Qin Cheng, and shouted angrily in a low voice: "Are you the wife of the Minister of War in Daliang?!"
Qin Cheng protected Li Xiaolan behind her, and faced the cold light of Ma Shan, her eyebrows slightly furrowed: "We, mother and daughter, are just village girls. Could it be that you recognized the wrong person?"
A flash of coldness flashed in the warrior's eyes: "Then there's no need to keep you!"
As soon as he finished speaking, the horse spear in his hand was already stabbed towards Qin Cheng.
…
Tianji camp, workshop.
Lu Ming led a group of skilled craftsmen to complete the construction of the tin tank.
The raw materials for refining glass are also piled in a corner of the workshop.
Once everything is ready, the next step is to officially start construction.
Because colored glaze was still an extremely scarce luxury product in this era.
In order to avoid leakage of the manufacturing method, Qin Feng drew a warehouse next to the workshop specifically for refining colored glaze, and only allowed Lu Ming to be present. If Qin Feng was unable to do anything else in the future, Lu Ming could take over.
Qin Feng first ground all the raw materials and ground them as finely as possible.
Then record the ratio of various raw materials in a book, mix them evenly, and put them all into the kiln.
After Qin Feng and Lu Ming's transformation, the furnace in front of them already represents the highest technology of the furnace in this era. However, because the fuel is only charcoal, the maximum temperature it can reach is far from enough to make glass.
Since there was no thermometer, Qin Feng could only rely on his knowledge to judge that the temperature in the furnace was at most 1,200 degrees.
But it takes 1,700 degrees to melt molten glass.
There is a difference of five hundred degrees. For this era, it is simply as difficult as climbing to the sky.
Fortunately, Qin Feng had already thought of this problem and asked Qin Xiaofu to go to the Ministry of Industry to buy some "stone yellow", which is sulfur, used to smelt iron.
By placing the Shiliu yellow grinding powder into it, the temperature requirements can be greatly reduced and the glass liquid can be obtained.
Seeing the bright red liquid, Lu Ming, who was standing by, couldn't help but be shocked: "Master, is this the glass liquid you are talking about? It is as clear and bright as molten iron!"
Qin Feng went into battle in person, wearing thick gloves, taking out the glass liquid from the furnace, and shouted at Lu Ming: "Don't be stunned, hurry up and pour it into the sink!"
Lu Ming finally came to his senses, followed suit, took out a vat of glass liquid from the furnace, and poured it into the tin bath along the funnel.
The tin bath has been filled with water in advance.
When the molten glass was poured into the tin tank, there was a sizzling sound and a black mass sank directly to the bottom of the water.
"Fuck!"
Qin Feng looked at his painstaking masterpiece and screamed: "Damn it! I have been busy all day, and the failure was so damn quick! Is it true that every other line is like a mountain?"
Qin Feng looked at the glass liquid that was instantly cooled by the water, slapped his head, and secretly cursed himself for being confused: "Failure is success, damn! I can't imagine using water as a float solvent. The temperature of the water is too low, and the density is not enough. , it is impossible to make the glass liquid float above..."
But looking at the black thing, Qin Feng suddenly understood and slapped his thigh: "Lu Ming, you immediately order the workshop to start working at full capacity and cast two iron boxes. The big box should be placed inside the small box, leaving a gap in the middle. Uniform gap space.”
One second ago, Qin Feng was baring his teeth and about to bite, but this second he was wagging his tail again.
Lu Ming was confused, but he still followed the instructions. He went to the workshop and ordered the blacksmith to turn on all power. Since there were many ready-made iron plates, it was not difficult to cast the iron box. Soon Lu Ming sent the box to the glass room.
Qin Feng repeated his old trick and introduced all the remaining glass solution into the iron box, using the gaps in the iron box to force the shape.
Over time, the liquid glass gradually cools, eventually forming crystal clear glass.
Qin Feng followed the gap inside the box, smashed the bottom of the glass, then turned the box over, and poured out the four pieces of formed glass.
Looking at the crystal clear glass liquid, Lu Ming was stunned.
I don't know how long it took for me to come back to my senses, with a look of disbelief on my face: "Young... Young Master, I know about colored glaze, but most of them are colored glaze balls or colored glaze vessels. Such a large and thin piece of colored glaze is unheard of."
Qin Feng had collapsed on the ground, breathing heavily from exhaustion.
But looking at the four thin glass pages, I felt filled with a sense of accomplishment.
After many twists and turns, this glass page was finally refined!
Lu Ming squatted on the ground. Because the glass sheet was too thin, Lu Ming did not dare to touch it. He just lowered his head and looked at it, his eyes full of amazement, but then he was confused: "Master, this glass sheet is good, but it is too fragile." Now, what can we do? It’s better to just build an iron ball mold and refine the glass ball.”
Qin Feng rolled his eyes and said angrily: "What do you know! It's not like the palace has never seen glazed balls or glazed utensils. This glazed page is a good thing."
Since he decided to refine glass, Qin Feng was not doing it for Princess Qiyang, but to "give gifts" to the saint.
After all, they had a feud with the Lin family before. Who knows what dirty tricks the Lin family would use to retaliate against the Qin family.
Qin Feng plans to make this glass into a "glass window" and install it directly in the imperial study room, so that the saint can see Qin Feng's masterpiece when he looks up, and miss the good things of the Qin family...
Qin Feng regained some strength, pointed at the glass, and said excitedly: "Take someone to polish this glazed page into a square shape, and then order a carpenter to make it into a window. As for how big it is... I will ask Qin Xiaofu to make it a window later." The dimensions of the study window will be sent to you.”
Lu Ming looked at Qin Feng blankly, these words were beyond his understanding.
