"So serious?" Luo Youde didn't expect that he still needed to fake his death, and he also needed to be incognito.

"I'll take care of you America, if he is willing to marry a salamander, I don't object!" Hong Tao began to raise, and even gave up his daughter. However, he didn't say anything and asked Hong Salamander to marry Luo Meimei, and only promised not to object.

“…… When are you going to let me die? Luo Youde didn't resist Hong Tao's temptation, as a father, his biggest weakness is his son's future, Hong Tao hit a fatal blow.

"Don't be in a hurry, I'll let you live a few more days, and it's not too late for you to die when you arrange the affairs of the Huanqiu Company and the Strait Company...... Hahaha. A wicked laugh came from the prime minister's office, and the guards standing outside the door frowned and got goosebumps. They don't know who Emperor Hong is pit this time, usually he doesn't laugh like this, as long as he smiles like this, he is guaranteed that someone will be in bad luck.

Since Luo Youde left Jinhe City sullenly, Hong Tao seems to have suddenly changed a person, with more smiles on his face, and he is no longer scolding people in the office building of the Prime Minister's Office all day long. Even his four apprentices felt a lot better, and even if they did the test wrong, they would no longer be sneered at by this fucking master, as long as they didn't violate the safety system and operate in violation of the rules, they would generally be encouraged.

After solving a matter that Hong Tao thought was very important, it was necessary to be in a good mood. As soon as the mood is good, the work efficiency will be improved accordingly, and the motivation will be enough. Now Hong Tao is tossing in Jinhe City with the mood of standing on the last shift, and every time he finishes a job, he secretly encourages himself: You have left another inheritance for your son, in order to be worthy of your son, come on!

The glass had been figured out, and there were glass containers in the laboratory for experimentation, but he was not satisfied, and he wanted to seal the windows of the captain's cabin of his new battleship with glass. The signal lights and the lights in the cabin were also replaced with glass-covered gas lamps. The brightness of the gas lamp is comparable to that of the high-wattage electric lamps of later generations, and it is currently the best choice for lighting and signal communication.

The fuel for gas lamps is kerosene in Jinhe City, and there is no shortage of hemp in Manila. It only needs to be mixed with linen fabric to form a small net, which is ignited with alcohol in advance, and then the kerosene in the oil pot is pressurized, and the sprayed mist kerosene burns instantly when it touches the hot net. to obtain an unusually bright white light. The key to this lamp lies in this small net, the manual pumping of the pressurized oil pot and the bicycle pump is a principle, which can be created by a goldsmith, and is more exquisite and durable than the industrial products of later generations.

But for this net to emit bright incandescent light, it must be soaked with a solution of a rare radioactive element, a radioactive metal element called thorium (tu). It is an associated mineral that can be dissolved from monazite with sulfuric acid to form a thorium sulfate solution. When exposed to high temperatures, the hemp mesh quickly burns to ashes. But it still retains the shape of a net. The thorium sulfate inside the net becomes thorium dioxide, which remains in the ashes of the net.

Thorium dioxide has the property that it emits a bright white light when exposed to high temperatures, and the instantaneous combustion of jet-like kerosene provides this temperature. Therefore, the high brightness of the gas lamp should be the credit of thorium, and kerosene is just an auxiliary tool. If the net does not burn well and breaks, the brightness of burning with kerosene alone is basically no different from that of a horse lantern.

Hong Tao used to go fishing in the wild without electricity. Gas lamps have many advantages over battery lamps. The first is that it is very bright, a gas lamp can easily illuminate a space of nearly 100 square meters. This is only matched by high-pressure halogen lamps used on construction sites. But gas lamps don't use electricity, and kerosene only needs a small amount, which is much easier than carrying batteries and generators. In addition, the gas lamp emits a lot of heat while emitting light, which can be used to heat up the tent on cold nights. In addition, the gas lamp is not afraid of the wind, as long as a glass lampshade is put on the outside, it is difficult to blow it out by the wind.

Combines these advantages. In the absence of electric lighting, gas lamps are the best lighting tools in this space-time. Whether it is used for navigation signals, lighthouses, cabin lighting, fishing, or for urban road lighting, field work lighting, and life lighting, the only thing that needs to be paid attention to is to prevent scalding and ignition fires.

But there is a tricky thing to solve here, otherwise not only the gas lamp will not be able to make it. Even the laboratory glassware that Hong Tao had been looking forward to could not be made. Ordinary glass is smelted at a high temperature of thousands of degrees Celsius, which can withstand heat. However, due to the material relationship, the coefficient of thermal expansion is different, and if the temperature rises too quickly, it will not dissolve, but it will explode. If this problem is not solved, glass products such as gas lamp shades and beakers can only be thought of.

How to solve the problem of heat resistance of glass? There are many ways to do this, but only two are applicable to the current level of science and technology. The first is to improve the blowing process, as far as possible to blow the glass products that need heat resistance thinner and more uniform, in terms of physical characteristics to prevent glass bursting. The second is to increase the silicon content in the glass raw material, so that the glass can also withstand high temperatures.

The first problem is relatively simple to solve, practice is enough, once not a hundred, a hundred times not a thousand, slowly can summarize a set of appropriate glass blowing process. The second problem is a bit troublesome, the main silicon raw material for firing glass is sand, which sand contains a large amount of silicon, Hong Tao has no reagents to test, can only select different sand samples from different places, and then test the finished product and then carry out destructive tests.

This workload is a bit large, not only the beaches near Jinhe Bay have to collect samples, but also the coastal countries from the north to the Southern Song Dynasty and the south to Jawa Island need to be collected, and then the detailed origin is marked and sent back to the glass kiln at Yinhekou for test firing.

Hong Tao was still relatively lucky, only tried to burn more than 30 samples, and found two sand samples with relatively high silica sand content. One is near the port of Brunei in Kalimantan and the other is on the island of Java. Now that you have the right sample, let's start sand selection. The sand from these two places was transported back by boat, and then the silica sand with a heavier specific gravity was flotated by mud flotation. This is the raw material for making heat-resistant glass, and ordinary glass does not need to be so troublesome.

A new technology was most exciting when it first came to prominence, and in the first half of 1241, Hong Tao once again became an idol in Jinhe City. The people took their emperor to a new level, and each house placed a clear glass statue of His Majesty the Emperor as a token of their gratitude.

Since the emergence of a new factory at the mouth of the galaxy, the national welfare of the entire empire has risen to a new level. Because the country has another big factory that is making money every day, the people can get a considerable dividend at the end of the year. From ancient times to the present, the common people have never been sad because of the amount of money, they will only be happy, and then they will naturally remember who made them rich.

"How much does this have to sell! A full 10,000 glass statues, even if they are cast from molds, are enough for three glass kilns to dry for three months! Loser! But Hong Tao couldn't be happy, this decision was not his proposal, but the group of people in the council, and they couldn't stop it. Not only can't he stop it, but he can't be unhappy on the surface, so he can only complain at home.

"I think it's a good thing, it's much more beautiful than standing a statue in the square. Everyone supports you, and there is nothing to repay you, you are not happy to build a big palace for you, and it is also a meaning to make a statue to put on display. Other emperors can't put it if they want to, and no one is willing to ask for it, let alone buy it for a silver coin. "Today, the old man Bofu is very happy, his son-in-law is not only the emperor, but also an emperor who is loved by everyone, and it is worth making a few hard dishes and drinking two sips. Not only did the family want to celebrate, but he also invited the old men of the in-laws, the Huang family, the Wen family, the Bu family, the Weng family, the Ou family, and the Rong family to his home, and set up ten tables of banquets, just like holding a wedding banquet.

"That's it, if you want me to say that Brother Chen and Brother Bo have vision, why did Tao Lingzi let you catch up in the first place, if only I were here, now I can also be a royal prince." The old man of the Yellow Sea was a little floating after a few glasses of wine, he didn't drink it just right, and he drank too much.

"If you want me to say that Tao Yanzi should float to the side of our Wen family's ship, in that case, the big ship would have been built a long time ago, and the two of you have been delayed for several years!" Wen Lao Er did not show weakness, and began to raise the bar with the Yellow Sea with a red rosacea nose. One of them is in charge of agriculture and the other is in charge of shipbuilding, and they happen to be land and water, natural enemies, and no one looks down on anyone.

"Alas, if only Qihong were still alive, my little grandson wouldn't have lost his father early......" Chen Mingen's alcohol consumption was originally good, but it was easy to drink too much when he had something in his heart, and listening to everyone's excitement, he thought of his son who died in battle again.

“…… I said, Brother Chen, people can't be resurrected after death, so it's okay not to mention this matter. Our Tan family was born with this fate, if it weren't for Tao Lingzi to bring us here, Qihong's child might not be alive now, who knows which time to catch the sea will be confessed. As soon as Boss Wen heard Chen Mingen mention Chen Qihong again, he immediately stood up for Hong Tao. This matter has become a tacit understanding in Jinhe City, and no one will say it in front of Hong Tao, because every time he talks about it, Hong Tao, who originally laughed with everyone, immediately lost his smile.

"What Lao Wen said is reasonable, life and death are fateful and wealth are in the sky. Our Tan family has never complained about the people in the territorial waters, if they all say so, who is willing to lead everyone out to sea? This is also the old man Rong left early, otherwise you would have been hit on the head by now. Don't think that if you are the emperor's father, no one will dare to touch you, and if you are in a hurry, our brother will throw you into the river to sober up. "Old man Bofu is not very happy, today is the place where he gathers, it was a happy thing, how can you say this, even if it is Hong Tao's godfather, it will not be.
