Liulichang is located near Huimin Pharmacy, about ten miles away from Huimin Pharmacy. The thousands of acres of land originally approved were put to use at this time, and it was large enough. It doesn't matter if it's far away. Even after working on it for so long, one hundred acres of land has not been used.
On the seventeenth day of the second lunar month, an auspicious day, Liulichang officially hung a plaque.
The weather was good, the sun was warm on the body, the auspicious time had arrived, firecrackers were going off, and the plaque of the Fuyin Zheng Yiyan Glass Factory was officially hung.
The crowd of onlookers made bursts of noise. I don’t know where so many onlookers came from in such a remote place. Maybe it is people’s nature to watch the excitement.
Of course, there are also officials from Yingtian Mansion, colleagues from brother units, and Huimin Pharmacy also sent people to support him.
After watching the excitement, everyone quickly dispersed, and Zheng Xiong and a group of colleagues approached the door of the glass factory.
After visiting the glass factory and arranging for colleagues, Zheng Xiong held a simple meeting with the craftsmen of the glass factory.
"Today is a memorable day. The glass factory is officially established with a plaque. This is just the beginning. We are not a glass factory, and you are not just craftsmen. Each of you can use your own ideas to create glass. Once the glass is made, Everyone has a reward, let alone wealth and wealth, it will definitely not be a problem for you to live and work in peace and contentment. I, Zheng Xiong, will leave these words here today. If you don't do it tomorrow, you can come to me at any time."
The routine remains unchanged, it is just like painting a cake. Since ancient times, the routine has won the hearts of the people, and it has always been tried and tested.
No, the applause from the audience is the best answer. People nowadays really don’t have high requirements. Food and clothing are the greatest happiness. Not to mention, a monthly salary of 600 yuan is enough to live on.
After the meeting, it was time for dinner. Zheng Xiong had booked a small restaurant nearby. Zheng Xiong and a group of colleagues went to the private room. Those who were not classy ate and drank in the lobby. It was the same in modern times and ancient times. Classes have always existed. Zheng Xiong also changed. Nothing.
After eating well and drinking well, the cooking officially started the next day. People who had a big meal were working hard today.
The process of making glass for the first time was not complicated. Several people had working experience in Liulichang. The glass factory was also a replica of Liulichang, copying the gourd and the dipper.
The colored glaze in Liulichang is mainly imitation jade, and a lot of miscellaneous materials are added to resemble jade, which is also a wrong way. The money is controlled by the ruling class. The wealth of the entire society is just such a big pie. After it is divided, there is no way to open up the source. After the class solidification , all that was left was to play, and jade-like colored glaze was favored by capital, and it gradually drifted away from glass.
What Zheng Xiong has to do is remove impurities, the purer the better.
The first furnace was not unconventional, it just used the method of making colored glaze, which is essentially a chemical reaction between sand and some calcium carbonate, and it was started directly without adding anything else.
Soon, the shape of the sand changed under high-temperature calcination. When he saw that it was almost done, the old master poured the solution into a mold on the side, pressed it into a plate shape with a tool, and waited for cooling.
The first time you open the furnace, it only needs to be successful. There are not so many requirements. The glass will be a little green after cooling. It's okay to say it's glass. After all, it's parted ways with Liuli, but it just can't reach the light transmittance of later generations.
Zheng Xiong picked up the glass and walked outside. He looked at the sun and saw that the light transmittance was not very high. It was stronger than the beer bottles of later generations, but the strength was limited.
The craftsman following Zheng Xiong was slightly uneasy. It was the first time and he was afraid of screwing up.
"Not bad. What you have to do next is to continue to improve the transmittance of the glass. Use this as a template. When you can clearly see the things on the ground through the glass, it will be considered successful and you will be given bonuses at that time."
After hearing Zheng Xiong's reply, everyone breathed a sigh of relief, and the bonus stimulated everyone even more. Although they didn't know how much, everyone's enthusiasm still increased and they replied loudly.
"yes"
The next few days were filled with constant experiments. With the methods given by Zheng Xiong and adjusting the proportions of various additives, the light transmittance was still improved a lot, but it still did not meet Zheng Xiong's requirements.
Although Zheng Xiong was not in a hurry, he still had to make some preparations in advance, such as polishing the lenses and accumulating some experience.
A group of people were recruited to polish all the semi-finished glass.
As a few days passed, the light transmittance of the glass was slowly improving, and the polished lenses looked decent. However, if the light transmittance was not good enough, they would be of little value.
As a last resort, Zheng Xiong could only grit his teeth and buy some natural crystals at a high price to test first.
The crystal that Zheng Xiong specially selected has good light transmittance and looks purer than ordinary glass.
Polishing the convex lens with crystal means constantly adjusting the distance between the two lenses and the ratio of the two lenses. This is another time-consuming project.
Likewise, without glass, Zheng Xiong couldn't bear the consumption of crystal alone, so he had no choice but to stop.
Found an alternative.
Speaking of microscopes, the inventor of this thing must be mentioned.
This person is a veteran.
That's right!
This person is exactly...
Robert Hooke.
Actually.
According to later research, it was the Johnsons and his sons in 1595 who really thought about the working principle of the microscope and invented the first microscope.
But these two unlucky guys didn't make any important observations with these instruments, and they didn't do anything after they were made.
Therefore, in the history books, the right to invent the microscope became a battleground between the other two people:
Leeuwenhoek and Robert Hooke.
The degree of confusion between these two people is so high that even the Biology book published by the People's Education Press contains errors.
First let’s define it from a point in time:
Robert Hooke's invention of the microscope preceded Leeuwenhoek's by twenty years.
However, the microscope invented by Hooke only had a magnification of 20 times, while Hooke's magnification was as high as 270 times.
Therefore, the real statement should be that Hooke invented the microscope, and Hooke invented...or improved the high-power microscope.
In addition, in terms of biological contributions, although Hooke discovered cells, he observed slices of cork.
After Hooke zoomed in, he discovered small spaces one by one, and named them after the English cell.
But in fact.
What he observed were dead cells; all he saw were the remaining plant cell walls.
Leeuwenhoek observed living microbial bacteria, so he is considered the founder of microbiology.
It should be noted here that Robert Hooke preferred to use a well-made compound microscope, that is, a microscope that contains two lenses: an eyepiece and an objective lens.
The simple microscope used by Leeuwenhoek had a lens mounted on a metal plate, and the sample to be observed needed to be inserted into the needle tip in front of the lens in advance.
Hooke also described another single-lens microscope design in the preface to his book. The design is very simple. Just drill a hole in the brass sheet and insert a convex lens ground with molten glass beads.
Despite the simple design of this single-lens microscope, the effect is surprisingly good. The magnification can reach hundreds of times and the resolution can reach the micron level. Although the design principle is more advanced, it will take at least 150 years of development for compound microscopes to achieve this kind of imaging quality.
It is said that the microscope he built later had a magnification of 200 and a resolution of 1 micron. It is truly a craft that transcends the times. Modern ordinary optical microscopes only have a magnification of 800 and a resolution of 0.5 microns.
Leeuwenhoek saw bacteria, red blood cells, sperm (stay home and observe this hahaha), and other microorganisms under the microscope he made. This was his breakthrough, because Robert Hooke just looked at things that everyone knows in more detail, such as the hair on a flea's legs, the eyes of a fly, and the grid of a cork slice. It's just not very clear. And Leeuwenhoek opened the door to microorganisms. This is a new and unknown world.
Therefore Leeuwenhoek is revered as the father of modern microbiology, but the single-lens microscope he used should indeed be patented by Robert Hooke.
There is no way, those who rub microscopes are ruthless people, real technical work requires perseverance and patience. Zheng Xiong’s plan is also to use a large number of compound microscopes to popularize some knowledge of virology and biology. With exploration, single transmission and compound microscopes will naturally develop.
However, the hard-working spirit of the Chinese people is engraved in their bones, so you can give it a try.
