Chapter 530 Did the ancients use color-changing ink?
No one is aware of the principle behind the color produced by the refraction of prism! Even if they see it, almost no one will explore it in this era.
Not to mention this color-changing ink and photodenaturation!
"Quick, bring it up and take a look!"
Soon one craftsman was hunched over, holding an ink cartridge, while the other craftsman came to Zhu Gaoying with a pen and a scroll.
"Your Majesty, please look!"
Slowly unrolling the scroll, a craftsman took a brush, dipped it in ink, and drew a horizontal line on the paper.
"Huh?"
Yang Shiqi, who was standing behind Zhu Gaoyan, was a little surprised when he saw that the horizontal lines drawn with the same ink actually showed different colors.
I thought that what His Majesty said was a bit nonsense. Even if such a thing existed in the world, it would be difficult to develop it in a short time. However, I did not expect that in just a few days, this kind of color-changing ink could be used.
Appeared in front of him!
This is incredible!
What a stroke of genius!
Yang Shiqi was shocked. He stood next to the desk and paced back and forth, looking at the horizontal lines on the paper from different angles. Did it really change color?
"It's so amazing, it's red for a while and yellow for a while!"
"How did you do it?"
Yang Shiqi is very eager to know that if he masters the method, then outsiders will not be able to imitate banknotes made with this kind of ink, and their value and safety will be greatly improved.
In the future, the convenience of paper money will definitely make the Ming Dynasty's economy take off!
If it becomes popular in surrounding countries and is recognized by other countries, then wouldn’t our Ming Dynasty’s business be able to develop all over the world?
If we use a current word to describe it, it would be the economic hegemony of Ming Dynasty Baochao!
"Reporting to Mr. Yang, reporting to Your Majesty, this exquisite method was not actually thought up by Xiaguan, but accidentally discovered by Xiaguan when he was looking through the ancient books of his predecessors!"
Looking through ancient classics?
Zhu Gaoying was stunned after hearing this, and said, "I'll go, the ancients had already used color-changing ink so early!"
"There is such a strange book in the world?"
There was such a book, and although he wanted to read it, Yang Shiqi looked at the official eagerly, but the other person showed a troubled expression.
"This, I'm afraid it won't work..."
"What's wrong?"
Yang Shiqi's expression immediately changed. If such a strange book were lost, it would be a great misfortune for our entire nation!
"Because I didn't find this book, I just found a remnant page of this book."
As he said this, the official took out a yellowed page of paper from his sleeve. There were many cracks on it. It looked like it would break when touched. It could be seen that it had been there for many years.
"At that time, this page was hidden in a book that had been dusty for many years. When the official was rummaging through it, he accidentally dug it out."
"So, Wei Chen copied the above text one by one and asked the Hanlin scholars for advice, and finally he roughly pieced together what he meant!"
Zhu Gaotian carefully took the paper and placed it flat on the table.
"The writing on it seems to be the small seal script of the Qin Dynasty?"
Unexpectedly, this method actually appeared during the Spring and Autumn Period and the Warring States Period.
"Xiaguan also followed the above method and made many attempts and improvements before finally making this color-changing ink that switches from red to yellow!"
Biansaimo is simple to say, it is to make pigments and dyes into tiny pigment capsules, and then dissolve them in the binder.
These small capsules can be small particles or macromolecular structures.
According to the refraction of light produced by these pigment particles at different angles, different colors appear.
This is the most basic color-changing ink.
The method recorded on this flimsy piece of paper roughly involves gathering some natural pigments into tiny structures and then mixing them into rice milk.
However, these natural pigments have a disadvantage, that is, these pigment particles are organic matter and are easily decomposed quickly under conditions such as sunlight, temperature, humidity, and time, thereby losing their original color.
The horizontal line on this paper is the best proof. Not long after it was painted, the bright red and yellow on it already had a dim feeling, as if it had been covered in dust for a long time.
"good!"
Although it is still far from the final product required by Zhu Gaoyang, this has undoubtedly solved a big problem. The manufacturing method of color-changing ink has been determined. The most important thing left is to select one that meets the requirements and can be used for a long time.
Preserved pigment raw materials!
"Okay, okay!"
Zhu Gaoyan was quite satisfied with this,
"Zhang Qixin, did you hear what they just said?"
"Yes, Your Majesty, the guilty minister just heard it!"
"Okay, since you know, I'll leave this to you!"
His Majesty was about to give him a task. Zhang Qixin immediately raised his head after hearing this. This was the opportunity His Majesty gave him. He must handle this matter well and never let down His Majesty's kindness to him!
"Your Majesty, please leave it to the guilty minister. The guilty minister will definitely complete the task and will definitely live up to your majesty's expectations of the guilty minister!"
"As for you..."
At this time, Zhu Gaotian turned around and looked at the official responsible for supervision this time.
"You've done a good job, but I haven't thought of a reward for you yet. How about this? If you say something, as long as it's not too outrageous, I will satisfy you!"
"Your Majesty, I would like to thank your Majesty. I have done my duty to contribute to the Ming Dynasty. How dare I ask for benefits from Your Majesty!"
"I hope that I can surrender to His Majesty forever and dedicate my whole life to the Ming Dynasty. I will be satisfied!"
"Hmph, you will be rewarded for your merits, and you will be punished for your faults. I personally said that I will reward you, how can I not reward you?"
Zhu Gaoying thought for a while and made up his mind.
"Well, I plan to set up a department in a while, called a bank, to replace all the banks in the world!"
Replace all banks?
Isn’t this the one who manages money and the treasury?
"I will establish a central bank in the capital, and local banks will be established locally, all under the jurisdiction of our Ming Dynasty government!"
"And you are the president of this central bank, responsible for wholesale loans, in charge of the flow of funds in the world, and even have the right to mint currency!"
After the official heard this, his whole body floated to the sky. He didn't know what kind of bank this bank was, what official rank it was, but it was definitely a rich (negative) position, and all the money in the world belonged to it.
I govern, and I can even mint currency!
It is no exaggeration to say that if I become the president of this bank, everyone in the world will be my younger brother in front of me!
