Liuli Factory is located near Huimin Pharmacy, ten miles away from Huimin Pharmacy, and the thousands of acres of land approved at the beginning also came in handy at this time, which is big enough. It doesn't matter if it's far away, it's useless to toss a hundred acres of land for so long.

On the seventeenth day of the second month of the lunar calendar, the auspicious day of the zodiac, the Liuli Factory officially hung a plaque.

The sky is beautiful, the sun is warm on the body, the auspicious time has arrived, the firecrackers are ringing out, and the plaque of the Fu Yin Zheng Yiyan Handbook Glass Factory is officially hanging.

The crowd of onlookers made a burst of noise, and I don't know where so many onlookers came from such a remote place, maybe it is people's nature to watch the excitement.

Of course, there are also subordinate officials of Ying Tianfu, colleagues from brother units, and Huimin Pharmacy also sent people to come to the scene.

After watching the excitement, everyone quickly dispersed, and Zheng Xiong and a group of colleagues approached the gate of the glass factory.

After visiting the Lower Glass Factory and arranging colleagues, Zheng Xiong and the craftsmen of the glass factory had a simple meeting.

"Today is a memorable day, the glassworks are officially inaugurated, and this is just the beginning. We are not a glass factory, you are not just craftsmen, everyone can use their own ideas to create glass, make glass, everyone has a reward, not to mention the wealthy, so that you live and work in peace and contentment is definitely not a problem, I Zheng Xiong's words today are here, he did not do it, you can come to me at any time. ”

The routine remains the same, that is, painting cakes, and the routine has won the hearts of the people since ancient times, and it has been tried and tested.

No, the applause from the audience is the best answer, the current people's requirements are really not high, food and clothing are the greatest happiness, not to mention far, a month's salary of 600 Wen is enough to live.

The end of the meeting is the dry dinner session, Zheng Xiong has already chartered a small restaurant nearby, Zheng Xiong and a group of colleagues went to the box, and those who have no grade eat and drink in the lobby, modern and ancient times are the same, classes have always existed, and Zheng Xiong can't change anything.

Eat and drink well, the next day officially opened, the people who have eaten a big meal are working very hard today.

The first glass-making process is not complicated, and a few people still have work experience in the glass factory, and the glass factory is also an imitation of the glass factory, according to the gourd painting scoop.

The glaze of the glaze factory is mainly imitation jade, plus a lot of miscellaneous materials to the jade, but also deviated, the money is in the hands of the ruling class, the wealth of the whole society is such a big pie, and there is no open source method after the class is solidified, there is only play, the imitation jade glaze is favored by capital, and the glass is gradually distant.

What Zheng Xiong has to do is to remove impurities, the purer the better.

The first furnace is not unconventional, just use the method of making glass, which is essentially a chemical reaction of sand and some calcium carbonate, and does not add anything else, and directly creates it.

Soon, under the high temperature calcination, the shape of the sand changed, and seeing that it was almost there, the master poured the solution into the mold on the side, pressed it into a plate shape with a tool, and waited for it to cool.

As long as the first furnace is successful, there are not so many requirements, and the glass after cooling has a bit of turquoise. It's okay to say it's glass, after all, it parted ways with the glass, but it can't reach the transmittance of later generations.

Zheng Xiong picked up the glass and walked outside, looked at the sun, the light transmittance is not very high, stronger than the beer bottles of later generations, and the strength is limited.

The craftsman who followed behind Zheng Xiong was slightly apprehensive, the first time, he was afraid of messing up.

"It's not bad, the next thing you have to do is to continue to improve the light transmittance of the glass, just use this as a template, when you can clearly see the things on the ground through the glass, it will be done, and you will be given a bonus when the time comes."

After hearing Zheng Xiong's reply, everyone breathed a sigh of relief, and the bonus stimulated everyone, although they didn't know how much, but everyone's enthusiasm still rose, and they replied loudly.

"Yes"

The next few days were continuous experiments, coupled with the methods given by Zheng Xiong, adjusting the proportion of various additives, and the light transmittance was still improved a lot, but it did not meet Zheng Xiong's requirements.

Although Zheng Xiong is not in a hurry, some preparations still have to be made in advance, such as polishing lenses and accumulating some experience.

Another group of people were recruited to polish and pull all these semi-finished glasses over for polishing.

After a few days, the light transmittance of the glass is slowly improving, and the polished lens is good, but the light transmittance is not good, and the value is not great.

As a last resort, Zheng Xiong could only grit his teeth and buy some natural crystals at a high price to test them first.

The crystal specially selected by Zheng Xiong has good light transmittance and looks purer than ordinary glass.

After polishing the convex lens with crystal, it is to constantly adjust the spacing of the two lenses and the proportional size of the two lenses, which is another time-consuming project.

Similarly, without glass, Zheng Xiong couldn't afford the consumption of crystal, so he had to stagnate.

An alternative was found.

Speaking of microscopes, we have to mention the inventor of this thing.

This man is an old man.

That's right!

This person is ......

Robert Hooker.

As a matter of fact.

According to later research, the people who really thought about the working principle of the microscope and invented the first microscope should be Jensen and his sons in 1595.

But the two unlucky ones didn't make any significant observations with these instruments, and after they were made, they burped without doing anything.

Therefore, in the history books, the invention of the microscope has become a battlefield for the other two to tear apart:

Leeuwenhoek and Robert Hooke.

The level of confusion between these two people is so high that even the human-taught version of the biology book is at fault.

Let's start with a definition from the point in time:

In terms of microscopes, Robert Hooke's invention preceded Leeuwenhoek by twenty years.

However, Hooke's invention of a microscope with a magnification of only 20 times, and Hooke's was as high as 270 times.

So the real claim should be that Hooke invented the microscope, and Hooke invented... Or rather, a high-powered microscope has been improved.

In addition, in terms of biological contributions, although Hook discovered cells, he observed slices of cork.

When Hook zoomed in, he found small spaces one by one, and named them after the English cell.

But actually.

What he observes are dead cells, and all he sees is the remnants of the plant cell wall.

Leeuwenhoek, on the other hand, observed living microorganisms and bacteria, which is why he is considered the founder of microbiology.

It is important to note here that Robert Hooke preferred to use a well-made compound microscope, that is, a microscope with two lenses, an eyepiece and an objective.

The simple microscope used by Leeuwenhoek at the time had the lens embedded in a metal plate, and the sample to be observed had to be inserted into the tip of the needle in front of the lens in advance.

In the preface to his book, Hooke describes the design of another single-lens microscope. The design is simple, drill a hole in the brass sheet, insert a convex lens ground with melted glass beads, and you can use it.

Don't look at the simple design of this single-lens microscope, but the effect is surprisingly good, the magnification can reach 100 times, and the resolution can be on the order of microns. Although the design principle is more advanced, it will take at least 150 years for the compound microscope to achieve this imaging quality.

It is said that the microscope he made later reached a magnification of 200 and a resolution of 1 micron. It is really a craft that is ahead of the times, and the modern ordinary optical microscope has a magnification of only 800 and a resolution of 0.5 microns.

Under the microscope he made, Leeuwenhoek saw bacteria, red blood cells, sperm (stay at home to observe this hahaha), and so on. This was his breakthrough, because Robert Hooker just looked at the things that everyone knew in more detail, what flea legs hair, flies' eyes, cork slice lattice, these are all known to us, but we just can't see it very clearly. Leeuwenhoek, on the other hand, opened the door to microorganisms, 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 Robert Hooke's patent.

There is no way, those who rub the microscope by hand are ruthless people, real technical work, perseverance, and patience must be had. Zheng Xiong's plan is also to use a large number of compound microscopes to popularize some knowledge of virology and biology. With the exploration, the single-permeability, the compound microscope will naturally evolve.

However, the spirit of hardship and hard work of the Chinese is engraved in the bones, and you can try it.
