February is a hard and exciting month for the people in the village, especially for those students and those involved in the project research, but for Deng Shifeng, February is still a few days away, since February is called the month of technical breakthroughs, so let's add such a technical project as the icing on the cake......

It is said that Fu Wushuang Zhi, that refers to the luck of things, although in the field of technical research also pay attention to this bit of luck, but more important is the accumulation of experience and tireless exploration in the mistakes, if once the accumulation of a bottleneck, technological breakthroughs like a volcano eruption is not a very strange thing; No, the glass production research began at the beginning of the month, and at the end of the month, the workers and students of the glass factory not only took out the beaker test tube that Deng Shifeng needed, but even several beautiful wine glasses appeared in front of everyone at the same time.

A few clear glasses are clear and bright, and although some faint light colors can be seen through the early spring sun, it is quite good to achieve this kind of pure effect in this era. Those test tubes, beakers, and curved neck retorts were also well done, which basically met Deng Shifeng's needs.

"Teacher...... After the last two pots came out, we were so excited to see that we finally made a pure glass slurry, and everyone blew all kinds of things, and the result was ...... I didn't get much out of things, but the ingredients were basically ...... It's gone......"

In the technical breakthrough month, because each test of the glass group needs to be recorded in detail, so Qin Tian was divided into technical data records, because Qin Tian is one of the two students promoted by Deng Shifeng, and he has learned a lot of things, although he is young, he is already the leader of the glass group. It stands to reason that when the trial production is finally successful and the product is taken out, he should be full of smiles, but Qin Tian lowered his head and did not dare to face his teacher when he reported, and the voice of the report became smaller and smaller, and even the last three words were as small as mosquitoes and flies...... Thinking about it, it took a lot of raw materials and time, and it was not easy to get something like it, but because of a moment of playfulness, I forgot about the business, if it weren't for a few people at the last moment, I remembered that I hadn't blown the product that the teacher wanted...... It is estimated that a few people can't even get this little thing......

Although Qin Tian's play was a bit disturbing, Deng Shifeng did not blame these playful children much, but only stopped pursuing them after a slight warning. These people themselves are children, and if they are children, they will have a playful heart, and it is not realistic to ask them to have a strong self-discipline like Chengren, and there were so many people at the scene at that time, excessive reprimand will hurt these children, even if they want to criticize education, it is necessary to wait for the right time. Besides, things should be looked at from two sides, although the children's play is a bit unscored, but in the process of playing, they have mastered the blowing methods of various appliances due to many times of play, and at the same time, the size and specifications can be basically guaranteed to be consistent, and these finished products in front of Deng Shifeng's eyes are the best illustration. With an equal height and a well-proportioned body shape, students can blow even more complex glass pieces such as curved necks......

The main parts of the firearm are here, and the transparent glass test equipment has been successfully taken down, so what is going to happen next...... Naturally, it is to overcome the last hurdle - making thundermercury!

Originally, Deng Shifeng planned to use the sulfur produced in the north to produce sulfuric acid in batches, but now that the time is tight and the resources are scarce, whether it is the lead chamber method or the tower method, Deng Shifeng does not have the resources and time to build, Deng Shifeng can only sacrifice the dry distillation method of green alum oil, and sacrifice the sulfuric acid he needs from the gallium ore traded with Huang Zhangshi.

However, these things that are about to be engaged in not only have great dangers in themselves, but also have great damage to the environment when refining, the people in the village are their own intangible wealth, Deng Shifeng does not want to use these intangible wealth to be lazy and joke, and found a place near the iron factory with a more suitable wind direction, Deng Shifeng asked Zhao Carpenter to take the villagers to build a temporary chemical laboratory.

The conditions of this chemical laboratory are much better than the stinky nitrate refining workshop next to the iron factory, which is a shoddy project built of wood and thatch, and here not only the main support columns are made of iron products produced by the iron factory, but even the beams are made of steel to form a long-span indoor space. To be able to do this is to explore the embodiment of the results of the research on the steel structure materials of the iron tower, and to make the steel wind tower so that the old grandson is now very addicted to the construction of large steel construction, and he still plans to rebuild a new school and a large hall for the whole village to hold meetings, and every day in his spare time is to use charcoal on rice paper to make design sketches...... However, although the main material has been changed from shotgun to gun, the top shelter material is still made of bamboo products...... After all, there has been no development of a plate rolling machine to produce large sheets......

As before, before the production of these dangerous goods, Deng Shifeng once again emphasized the importance of safety with the students and workers involved in the development, and let them memorize the manual and response plan in advance. Since the students have participated in previous experiments, they still have a good understanding of safety responsibilities, what should be taken and what should not be taken, and what should be done in the first few steps have been explained in advance, and even in the standing position, those who should be next to Deng Shifeng should never walk around, but those who should be watching from a distance should not approach; And after many simulation drill steps to make the students and himself extremely proficient, Deng Shifeng began to take the students into the door of chemistry.

Due to the limited equipment, the raw materials required for distillation, and the time required for purification, after more than ten hours and four rotations, two kilograms of concentrated sulfuric acid appeared in two glass containers. In order to verify these things, Deng Shifeng conducted three experiments in front of the students, a passivation experiment, a blending experiment and a hydrogen explosion experiment.

The students were a little frightened and curious to see a dark dense ferric tetroxide film on the surface of a knife, but when Deng Shifeng approached the test tube that was said to have collected hydrogen with a lit noodle, a crisp pop startled the students...... The effect of this explosion made two of these students become the champions of various elementary theories of chemistry in later chemistry textbooks......

With a sufficient concentration of sulfuric acid, Deng Shifeng took the students to distill again, added saltpeter to the crude finished alum oil, and then slowly heated it, using the volatile surname of nitric acid to obtain concentrated sulfuric acid, in this process, Deng Shifeng did not directly work but all handed over to a few older students for cooking, only when there was a mistake in the step Deng Shifeng would speak out to correct, but the whole process Deng Shifeng was only at the beginning, because the students were a little nervous and the steps were wrong, after the students relaxed, Deng Shifeng didn't even have a chance to speak on the side. And although it is close to the third month of the lunar calendar, the temperature is still cold this year, and the temperature in the mountains will be lower than in the plains, and a large amount of cold water drawn from the mountains also ensures the smooth progress of the whole process.

In this process, as a punishment for Qin Tian's dereliction of duty in the supervision of the glass factory, Qin Tian and a few people honestly squatted in the laboratory and couldn't go anywhere, and distilled all the glass that the wine exchanged in the village last time was tossed out by himself, so as to obtain a higher concentration of alcohol for backup.

After getting rid of the two acids and alcohol, the next process of adding mercury must be done by Deng Shifeng himself. Thanks to the two trucks that haul the small blast furnace and the mini van that haul the salt, there are not only infrared thermometers that can detect thousands of degrees for steelmaking, but also electronic thermometers with needle-prick probes used in homes and food workshops from minus a few degrees to hundreds of degrees. and guarantee the safety of the most dangerous steps of the whole process.

However, no matter how much equipment helped, Deng Shifeng still prayed silently to several old-timers in his heart before he died:

"Xu Jianyin, Wu Yunduo, you are our famous Chinese scientists in the trial production of explosives, and you all came up with chemical bombing to support our national rejuvenation under extremely simple conditions; May you bless us for a safe and smooth completion of these experiments, and bless the Chinese involved in the production of dangerous goods today and in the future...... In order for us to Chinese live at the top of this world......"

Be careful and careful, be cautious and cautious, Deng Shifeng carefully completed the whole process of making thunder mercury. There were no thrilling dangers or surprises, and everything seemed to go smoothly and perfectly. However, no one knew that when Deng Shifeng came down from the test bench, the close-fitting thermal underwear had already been soaked with sweat; Although Deng Shifeng himself and a certain chemistry master in his brain have read the relevant materials on the production of these things in many publications, sitting in front of the computer and desk and reading the detailed information and explanations are not personally standing on the test bench to make these things frightening, Deng Shifeng does not want to enter the state of re-crossing early because of the failure of the experiment......

On the first day of the first month of March, this day means that the villagers will put a lot of experience and labor into the final stage of spring ploughing, and the villagers who can often go to various construction sites to find work are now trying to arrange all the time for spring ploughing......
