Not long after Guoguo and the other two left, the manager came over with thirteen cauldrons.
He looked at Li Chengqian expectantly.
Yesterday, Li Chengqian had promised him that he would give him an extra hundred taels of silver for every extra person!
Li Chengqian smiled and shook his head.
As expected, if you want the horse to run, you really have to feed the horse first!
"Leave the things here first. When you have time, go find Wang Shun to get the money.”
The steward nodded hurriedly, his face beaming with joy.
Alright, now everything was ready. All that was missing was the east wind!
Li Chengqian began to assign tasks.
First, he asked one of them to dig for sand while the other went to find a magnet.
Although everyone in the future knew that glass was made from sand, very few people knew the specific operation.
Even Li Chengqian had accidentally read an article when he was in university.
It was as if there was something else in the sand.
Then, when it was fired, it would cause impurities in the glass and it would not be so transparent.
Now, he could only try his best to filter them out first.
Not long after, the two people who went to look for things returned.
Then, Li Chengqian began to get people to take action.
First, he picked up the sand grain by grain, trying to only get the transparent things.
Just this process alone took a full two hours.
Then, he picked up the sand and used a magnet to absorb it.
If the metal in the sand was removed, the glass that was fired would have a different color.
After the raw materials were ready, Li Chengqian had someone wash the sand, put it into the crucible, and then flushed it into the blast furnace.
"Light the fire!"
He just had to wait for the rest of the time.
As for how to operate it, he had to figure it out bit by bit.
While they were firing the glass, Li Chengqian had also called for the black-armored army to clear out the area.
An hour later, Li Chengqian endured the heat of the blast furnace and opened the observation port of the blast furnace. Then, he looked at the current state of the crucible.
In the crucible, the original sand had melted into a fiery red liquid.
After thinking for a moment, Li Chengqian asked the workers to take out one of the crucibles.
He took out an iron rod with a curved head, reached into the crucible, and took out the entire lump of mushy liquid.
This was because the production of glass was different from other things.
For other things, he could use molds to help them fix their shapes, but not glass!
If he wanted to fix the shape of the glass, he would need to use tin as a mold.
However, there was another way, which was to use tools to draw the molten glass.
Under the effect of gravity, they would change their shape. When they cooled down, they would form the desired shape.
So Li Chengqian let Cheng Chumo hold the iron rod while he held a pair of pliers, constantly changing the shape of the glass liquid.
Cheng Chumo looked at Li Chengqian with his mouth agape.
His big head was full of doubts.
"Your Highness, is this the sand we just put in?!!!”
"F * ck!"
"Can sand be used to make iron?”
Li Chengqian ignored him.
He wanted to stabilize the shape of the glass before it melted.
After a while, the glass formed a cup-shaped object in his hand.
Satisfied with his craftsmanship, Li Chengqian threw the pliers aside and asked Cheng Chumo to hold the iron rod and wait for the glass to cool down.
This was because the glass would explode if it came into contact with something with a low temperature.
Therefore, before using the iron rod and pliers, Li Chengqian heated them up slightly in the blast furnace.
Not long after, the glass gradually cooled down.
But the finished product, emmmmm…
It wasn't that satisfying.
Because it was not the kind of clean and transparent one that Li Chengqian wanted. Instead, it had another color, and it looked especially awkward!
Li Chengqian instantly lost interest in the glass.
He took the iron rod and wanted to throw it into the blast furnace.
But just as he was about to do something, Cheng Chumo suddenly hugged his thigh.
"Your Highness, don't throw it!"
"Don't give it to me!"
Li Chengqian held the glass cup that had been sawed off and looked at Cheng Chumo in confusion.
"You want it?"
Cheng Chumo quickly nodded.
However, Li Chengqian still threw the glass cup that was not in good condition into the blast furnace.
"What do you want this trash for?"
Unexpectedly, as soon as he threw it in, Cheng Chumo squatted on the ground with one hand covering his chest and the other trembling as he pointed at Li Chengqian.
"This…this…is a treasure!”
"Such a large piece of glass…"
"My heart aches!"
Li Chengqian suddenly felt that he seemed to have underestimated the importance people in this era attached to products like glass.
In his opinion, these were just trash, but in their eyes, they were treasures.
He squatted in front of Cheng Chumo and asked with a smile.
"You said this is Liuli?"
Cheng Chumo was a little unhappy because Li Chengqian had thrown the glass into the blast furnace.
He nodded perfunctorily.
"Tell me about it."
Cheng Chumo said.
"Do you know anyone from the Western Regions?"
"They once brought a few pieces of glass to His Majesty!”
"At that time, many ministers were so envious that their eyes turned red!”
"Then, His Majesty said that he wanted to reward one piece. You don't know, but at that time, those ministers directly started fighting in the imperial court!”
"Fortunately, my father was strong and strong, so he snatched it!”
After saying that, he even rolled his eyes at Li Chengqian.
Li Chengqian rubbed his chin and asked Cheng Chumo.
"Tell me about that glass.”
"What's the difference between this and mine?”
Cheng Chumo said unhappily.
"Yours isn't as good as theirs!"
"Their colors are much better than yours!”
"Other people have all kinds of colors, but your color is too light!”
"And…"
Hiss!
As soon as Cheng Chumo finished speaking, Li Chengqian gasped!
F * ck!
According to Cheng Chumo, wasn't that the kind of colorful marbles that only children would play with in the future?!!!
Li Chengqian understood!
Glassware had a similar feeling to jade, and jade was a very precious thing in ancient times!
However, the color of the glass was more complicated than that of the jade…
Hiss!
What the f * ck!
This was the rhythm of making a fortune!
With the knowledge of the future, he really deserved to be rich!!!
