    Lu Bu hugged Princess Liu Yan's charming body, lifted her hands up and down, and said with a smile: "Did you know that before this, there was no glass with good light transmittance in the Han Dynasty, mainly some glass beads, which were smelted bronzes in the Western Zhou Dynasty.  Discovered at the time.¡±

    When smelting bronze, the main raw materials for bronze are malachite, tin ore and charcoal, and the smelting temperature is around 1080c. Glass usually refers to a silicate compound that is melted, cooled and solidified. Quartz sand is the main raw material for melting glass.  Other raw materials include soda ash and limestone, and the smelting temperature is 1200c.  In the process of smelting bronze, due to the melting of various minerals, the glassy material will appear in the discharged copper slag, wires or lumps made of silicon compounds, and some copper particles will invade into the glassy material.  , so it appears light blue or light green. These translucent and bright substances attracted the attention of craftsmen. After their slight processing, they can be made into exquisite glass decorations.

    Wannian Princess Liu Yan took a colorful bead from her head and handed it to Lu Bu: "Husband, do you think it is like this?"

    Lu Bu looked at this colorful, crystal-clear bead and nodded with a smile: "Yes, this is the colored glaze bead. According to the records of "Guang Ya" and "Yun Ji", for a long period of time, colored glaze beads  They all refer to the collective name for glass beads burned with fire and other transparent things. Do you still remember the Han Yuefu folk song "Mo Shang Sang" that I asked Kong Rong and others to edit before? The beautiful woman Luo Fu on her head has a Japanese  The bright moon pearl in your ear is the colorful pearl on your head."

    Lu Bu took the colored glaze bead and continued: "This colored glaze is the first invention of the ancients in our country. No such items have been found outside the Han Dynasty, but it developed very slowly and has maintained its inherent characteristics. It is both gorgeous and colorful.  , crystal clear and bright, but also has the disadvantages of being brittle, not resistant to high temperatures, and not suitable for sudden cooling and heating. This is because its main component is lead-barium and the firing temperature is low. Lead-barium glass is not suitable  The production of eating utensils is only suitable for processing into various decorations, ritual vessels, and funerary objects. Therefore, compared with ceramics, bronze, and jade utensils, glass utensils have narrow uses and cannot be developed. Moreover, colored glaze is difficult to clarify.  It naturally becomes an ideal alternative material that imitates jade and gemstones. If glass is regarded as a second-rate substitute for other things, then it will not matter if the glass is not pure. In fact, impurity will become its advantage and its use will be limited.  , the attraction is getting smaller and smaller, so for more than a thousand years, colored glaze has always been colored glaze and has never become transparent!"

    "Then how did you invent this kind of transparent plate glass?" Princess Wannian looked at the huge mercury mirror and turned to look at Lu Bu with admiration.

    Lu Bu smiled calmly and said: "We here are stuck in our ways, but in the Qin State (Roman Empire) to the west of the Western Regions, there are already craftsmen who mix and melt quartz sand, limestone, feldspar, soda ash, boric acid and other items in a certain proportion. It becomes  This kind of transparent glass is then drawn and shaped using a special method to become the glass we see before us, and then tin foil is pasted on the glass surface and mercury is poured in to become this mirror!¡±

    Lu Bu knew that rare things are valuable. If transparent glass products appeared in the late Eastern Han Dynasty, how rare they would be.  Before other merchants master this technology, it is possible for transparent glass products to sell for sky-high prices.  Lu Bu had studied materials science in his previous life and had a rough understanding of the manufacturing process and raw material preparation of transparent pure glass.  At the end of the Eastern Han Dynasty, Lu Bu had no time to spare, and he never thought of making money by making this thing. Now that the war has temporarily stopped, he suddenly thought of making glass products to earn money from the nobles and nobles of the aristocratic families.

    Lu Bu wrote down the raw material ratios and the manufacturing techniques of many glass products, especially flat glass, that he could recall, and also drew sketches.

    The production process of glass includes: batching, melting, forming, annealing and other processes.  The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, and boric acid, according to a certain proportion.  Match together.  The prepared raw materials are heated at high temperature to form a uniform bubble-free glass liquid.  The glass frit is melted in the kiln, an open flame is heated above the glass liquid surface, and then the molten glass is transformed into a solid product with a fixed shape through a certain shaping process.

    The only forming methods that can be used now are artificial forming. There are blowing, which uses a blowpipe to pick a ball of glass and blow it while turning it in the mold. It is mainly used to form glass bubbles, bottles, balls, etc.; there is drawing, which is  After blowing into small bubbles, another worker sticks them with a top plate, and the two people blow and pull them. It is mainly used to make glass tubes or rods; for pressing, pick a ball of glass, cut it with scissors and let it fall into the concave mold.  Then use a punch to press, mainly used to form cups, plates, etc.; free forming, after picking the materials, use pliers, scissors, tweezers and other tools to directly make handicrafts.

    In order to produce glass lenses, the glass flow is allowed to float on the surface of the molten metal to form flat glass. This method is called float method, which can make the glass flat, smooth and pull quickly.It is fast and has a large output. Then it is annealed and cooled slowly for a period of time to prevent the glass from cold explosion.

    After the glass mirror was created, the mercury mirror came into being. The process is actually very simple. Stick tin foil on the glass surface and pour mercury. Mercury is a liquid metal that can dissolve tin well, and then a layer of tin foil is formed on the glass.  A thin layer of tin and mercury alloy, this tin amalgam is so strong that it can adhere tightly to glass and become a real mirror.

    Lu Bu, Ma Jun, Zheng Hun and others compiled a detailed process and wrote down a detailed process. They found Li Liuli, the craftsman in charge of the glass factory. Naturally, his original name was not Liuli. Because of his high skill in making glass, he was known as "Li Liuli".  The gift name is Liuli.  Every time Lu Bu met this Li Liuli, he couldn't help but think that if this object was directly called glass in ancient times, wouldn't this Li Liuli be Li Glass (because gay men are called "boylove", usually abbreviated as bl, which happens to be  The abbreviation of glass is the abbreviation of glass, so people habitually call gay people glass).

    Zheng Hun, the minister of the Ministry of Industry, asked Li Liuli to summon the craftsmen below to start developing other glass products and mercury mirrors. The process was very simple, and they quickly formed a flow operation, making mirrors and other glass products continuously.

    After they were made, they were distributed according to certain quotas to Jinyang Yan family, Zhongshan Zhen family, Donghai Mi family and other aristocratic families who were related to Lu Bu, and asked them to compare the glass products, especially mercury mirrors, according to specifications and compare the prices of jewelry with the same weight.  , stipulating that one should cost at least 10,000 yuan, and also restricting the supply, allowing this mercury mirror to maintain a status of "rare things are more valuable" for a period of time.

    At the same time, the process flow is strictly controlled, and the relevant workers are strictly controlled in Luoyang City and are not allowed to leave the city. The process cannot be allowed to flow out. Although it is inevitable that some people will be able to see the clues from the physical objects, at least in the first three to five years, we can still see this sky-high price mirror.  Make some money on it.

    After Lu Bu married Princess Liu Yan, she became pregnant within a month.

    Not long after Lu Bu calmed down, he married Dong Bai again.

    Under the treatment of two miraculous doctors, Hua Tuo and Zhang Zhongjing, Dong Bai is no longer the poor little deaf-mute girl she was. Her hearing has recovered, she can speak slowly from simple words, and now she has no problem communicating normally with others.

    If you didn't know that Dong Bai was Dong Zhuo's granddaughter, it would be hard to imagine that the fat Dong Zhuo would have a granddaughter as small and cute as a pendant. Dong Bai is not tall, probably only a little over 1.5 meters tall, standing in front of Lu Bu  , two heads shorter than Lu Bu. In a blink of an eye, she was already twenty years old, and I'm afraid she won't grow any longer.

    Lu Bu, who is nearly two meters tall, would not take such a short woman to heart, but Lu Bu is not a coward who is strict with others and lenient with himself. He knows that the key to the problem is not that Dong Bai is too short, but that he is too tall.  , among Lu Bu's wives and concubines, except for Zhen Jiang, Wu Xia and a few others, the other women are less than 1.7 meters tall. Diao Chan is only a little over 1.6 meters tall, but this does not detract from her appearance.  A woman's height has never been a necessary condition for judging a woman's sex appeal.

    Although Dong Bai is short, the overall feeling she brings to Lu Bu is no less than that of Wu Xia, who is half a head taller than her. Dong Bai's face is delicate, white and delicate, and can be broken by blows. Her skin is like a baby's. Her facial features are exquisite and her eyebrows are picturesque.  , cute and cute. Although she is twenty years old, she looks like a loli. Although she is a loli, she is not short-breasted because she grew up in the northwest. She is used to eating beef and mutton. She is well developed and has two white and lively breasts.  The little rabbit is jumping around.

    After Lu Bu returned to Luoyang, he summoned Dong Bai after he learned that Dong Bai had recovered from his illness and had become a normal person from a deaf-mute.

    Lu Bu is busy with work and only sees Dong Bai once or twice throughout the year. Dong Bai is now studying with Cai Yan and Diao Chan in the women's college and participating in teaching assistant work. He is very busy, but the things hanging in her heart are always unresolved.  Dong Bai was looking forward to Lu Bu's audience day and night.

    Dong Bai is no longer the little girl of thirteen or fourteen years old back then. She is already in her twenties. She has never eaten pork and has seen pigs running. When a man and a woman meet, there is no need to say anything, just the meeting of their eyes.  They understood what they meant. Lu Bu had not taken good care of Dong Bai for so many years. Dong Bai still had deep attachment and love for Lu Bu in his eyes, which made Lu Bu feel a little guilty.

    When Lu Bu felt guilty, the only thing he could do to overcome his guilt was to marry the other person.

    Dong Bai's parents died early, and his grandfather Dong Zhuo also died after Wang Yun. However, Wang Yun was taken to Liu Bian, the young emperor of the Han Dynasty, and killed by Lv Bu. Lv Bu indirectly avenged Dong Zhuo. Dong Bai originally liked Lv Bu, so he treated Lv Bu for this kindness.  The feeling of attachment and dependence is even stronger.

    After living in Da Sima's mansion for several years, Dong Bai was undergoing recovery and treatment every day, drinking bitter medicinal soup, and often encountered cold looks and ridicule from the maids. The only motivation for her to persevere was Lu Bu. She dreamed of having a life.  One day, like those big sisters,Wearing a bright red dress to marry Lu Bu, the day is finally coming.  (To be continued.
