Otaku Engineer in Great Tang Dynasty Chapter 452: Want to make money!

　　 "By the way, Fu Bo! How many glassware have you made before?"

　　 Just when Fu Bo was about to go out and organize the manpower, Li Zexuan asked suddenly.

　　 Previously, the workshop developed glass, mainly for use on the front cover of the compass. Later, as the large fleet went south, the demand for the compass also languished, but the glass cave could not be idle. Li Zexuan ordered the workers, Continue to produce various patterns of glass and other glassware, although the output is not very high, but after so long, it must be a lot.

　　 This thing is very profitable~!

　　If the cement can't be produced, sell this batch of glassware, maybe it will ease the urgent need~!

　　 "Master~! You can finally remember~!"

　　 Fubo was taken aback, and then said with a bitter face: "According to your instructions, the glass kiln of the workshop continued to produce. The accumulation of glassware has now been piled up in a room! To say nothing, there are more than a thousand. Pieces~!"

　　 Speaking of this, there is a hint of complexity in Fubo’s expression. Before this, for all of them, colored glaze is a kind of superior luxury. If any company has a colored glaze cup, don’t put it Confess like a baby? But now, the colored glaze utensils in the workshop have been flooded. They are all piled up in the warehouse like garbage. The world is really changing too fast~!

　　 "Hehe~! That's just right~! Fu Bo, you will arrange for a group of people to pack this batch of glazed utensils in a while. The more beautiful the packaging, the better! Recently I will sell them at a good price~!" /

　　 Li Zexuan said excitedly.

　　 He knows the reason that things are rare and expensive, and the average price must be lower for so many colored glazes at once, but he can't wait anymore, he needs a lot of money.

　　 "Yes, master~!"

　　Fubo also breathed a sigh of relief, arching his hands.

　　"Um~! This is not enough~! Fu Bo, I have another way to make a glass mirror. The process is very simple. You can let someone make fifty faces first~!"

　　 Li Zexuan has the final say, these thousand glassware, under the most ideal situation, can only sell five or six million, so he thought of a very important derivative of glass-mirror .

　　 This thing believes that as long as it is a rich lady, they can't resist this charm, and naturally they will make more money.

　　 "Oh~? Master, you say~! Remember me."

　　 Fubo's eyes lit up, and he said quickly.

　　"Hehe~! This is very simple. Forber, you can ask someone to stick the tin foil on one side of the glass, and then pour the mercury. The tin foil will dissolve in the mercury and turn into a silvery-white liquid, and stick tightly to the glass plate. , So it will become a glass mirror that is a hundred times clearer than a bronze mirror~!"

　　 Li Zexuan said confidently.

　　 Speaking of mirrors, its history is more than 3,000 years ago, and the first people used bronze mirrors. It was made by casting bronze into a disc and polishing it smoothly and smoothly. The shadows of people illuminated by this bronze mirror are not bright. It will also rust and must be polished frequently.

　　 More than 1,700 AD, glass mirrors were born. Initially, people made glass mirrors: first stick a piece of tin foil tightly on the glass, and then pour mercury, because mercury can dissolve tin and become a viscous silver-white liquid-tin amalgam, tightly Stick it on the glass plate. The glass mirror is a big step forward than the bronze mirror, and it is very popular.

　　 At that time, only the factory in Venice would make this new type of glass mirror, and all European countries bought it, and wealth flocked to Venice like a sea. The mirror workshop was concentrated on Murano Island, surrounded by guards and guards and tightly sealed off. Later, the French government bought four Venetian mirror artisans with a lot of money and smuggled them out of the country secretly. Since then, the mystery of the mercury glass mirror has been revealed, and its value has become less noble.

　　 However, the ability of mercury-coated mirrors to reflect light is not very strong. It takes time to make, and mercury is poisonous, so it was later eliminated.

　　A modern mirror with a thin layer of silver on the back. This layer of silver is not coated, nor does it need to be electroplated, it is coated by the chemical "silver mirror reaction". Add glucose water to the ammonia solution of silver nitrate. The glucose reduces the silver ions into silver particles, which are deposited on the glass to make a silver mirror, and finally a layer of paint is applied.

　　 Li Zexuan also wants to make this kind of silver mirror. However, it takes a lot of work to make nitric acid. He wants to leave this difficult task to his future students.

　　 As for the key material of glass mirrors-tin foil, there was already in the Tang Dynasty. Tinfoil was a handicraft product unique to Shaoxing in the early years. In ancient times, its main purpose was to make money for worshiping ghosts and gods. It first appeared in the Han Dynasty.

　　"Can this happen~? Is it really possible~? Master~?"

　　 Hearing Li Zexuan's sentence "A hundred times clearer than a bronze mirror", Fu Bo was excited and asked quickly.

　　 "Of course, I don't have time to talk about some of the principles in it with Fu Bo, but as long as I follow what I said, I will be able to create this kind of high-quality glass mirror~!"

　　 "Haha~! Okay~! The old man, let's arrange it, let's arrange it!"

　　Fubo couldn't wait, and planned to go out and take people to do experiments.

　　Li Zexuan quickly grabbed him and said: "Fu Bo, wait~!"

　　 "What's wrong~!"

　　 Li Zexuan said seriously: "Mercury is very volatile. Once inhaled into the lungs~IndoMTL.com~, people will definitely be poisoned. If the workshop wants to use this method to make glass mirrors, it must first solve this safety problem! In this way, you Let people sew a batch of special masks, add a few layers of carbon powder to the masks, and then separate them with coarse cloth. The thicker the better! Those involved in the manufacture of glass mirrors must wear this special mask."

r/>　　 Fubo strangely said: "Master, can't you just use the same mask before? Why bother~?"

　　"Of course not~! This mask must be used~! Forber, listen to me~!"

　　 Li Zexuan said flatly.

　　 Ordinary masks are only anti-particulate, which is what we usually call dust, but mercury vapor is a toxic and harmful gas, so you must wear the kind of protective tool that includes a filter device. If it is not for insufficient conditions, Li Zexuan would think Let someone make a gas mask!

　　"Yes~! Master~! The old man will go and arrange these things now~!"

　　Fu Bo has no choice but to do what he says.

　　 "Um~! Fu Bo, go ahead~! I'll go to the editorial department of Houya~!"

　　Li Zexuan thought for a while, and left with Fubo.

　　 For this batch of glass, to sell a good price, the necessary publicity is indispensable, so he had to let Ma Zhou design the advertisement in advance.

　　 At this time, the superiority of "Datang Daily" is fully reflected! You can advertise yourself at any time!
