Otaku Engineer in Great Tang Dynasty

"Right, Uncle Fu! How much did the Glass appliance that you produced before?"

Just as Uncle Fu was ready to go out and organize the man, Li Zexuan suddenly asked.

Previously, Workshop developed glass, mainly for use on the front cover of the Compass. Later, with the big fleet going south, the demand for Compass was languishing, but the glass cave could not be spared. Li Zexuan told the workers to continue to produce various kinds. The glass of the pattern and other glassware, although the output is not very high, but it has accumulated so much for a long time.

This is a huge profit!

If the Cement can't make it out, sell the glassware, maybe it will be a relief!

"Young Master ~! You can finally think of it~!"

Uncle Fu glanced, and then bitterly said: "Before you told me, Workshop's Glass kiln continued to produce, and now that the glassware has been piled up in a room! Less than a thousand pieces!"

Having said that, there is a touch of complexity in Uncle Fu expression. Before that, for all of them, Glass is a luxury of aloof and remote. If there is a Glass Cup, it is not considered as a glass. Baby like it? But now, the Glass appliances of Workshop have been flooded, all of them are like garbage, piled up in the warehouse, this world is changing too fast~!

"hehe ~! That's just~! Uncle Fu. You will arrange a group of people to pack these pieces of Glass equipment for a while. The more beautiful the packaging, the better! Recently I have to sell them for a good price~!"

Li Zexuan is excited.

He knows that things are rare, and when you come up with so many Glass at once, the average price is definitely lower, but he can't wait, he needs a lot of money.

"Yes, Young Master ~!"

Uncle Fu is also sighed in relief, arched.

"Well~! This is not enough~! Uncle Fu, I have a method of manufacturing Glass mirror here. The process is very simple. You can make fifty faces first!"

Li Zexuan has roughly calculated that more than a thousand pieces of glassware, in the best case, can only sell for five or six hundred thousand, so I thought of a very important derivative of glass - the mirror.

This thing believes that as long as the wealthy family's lady can't resist its charm, it will naturally make more money.

"Oh ~? Young Master, you said ~!old man remember."

Uncle Fu's eyes are bright and busy.

"hehe ~! This is very simple, Uncle Fu, you put the tin foil on one side of the glass, then pour the mercury. The tin foil will dissolve in the silver into a silver white liquid, and stick it tightly on the Glass board, so that it It will become a mirror mirror that is 100 times clearer than the bronze mirror~!"

Li Zexuan said with confidence.

Speaking of mirrors, its history has been more than 3,000 years ago, and people started with bronze mirrors. It was made by casting bronze into a disc, polished and smooth. The silhouette of this bronze mirror is not bright. It will also rust and must be polished frequently.

For more than 1,700 AD, glass mirrors were born. At first, people made glass mirrors by first attaching a tin foil to the glass and then pouring the mercury, because the mercury can dissolve the tin and become a viscous silver white liquid - tin amalgam, tightly Stick to the glass plate. The glass mirror is a big step forward than the bronze mirror. It is very popular. It has become a treasure that aristocrats and nobles are competing to buy.

At that time, only the workshops in Venice would be manufactures. This new type of glass mirrors was purchased by European countries, and wealth surged into Venice like a sea tide. The mirror workshop was concentrated on the island of Murano, all around the post and guarded, tightly blocked. Later, the French government bought four Venetian mirror craftsmen with heavy money and secretly sneaked them out of the country. Since then, the mystery of mercury glass mirrors has been made public, and its value is not so noble.

However, the ability of the mercury-coated mirror to reflect light is not very strong. The manufacture is time-consuming, and the 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 is it electroplated. It is painted by the "silver mirror reaction" on Chemistry. Glucose water is added to the aqueous solution of Nitric Acid silver. The glucose reduces the silver ions into silver particles, deposits them on the glass to make a silver mirror, and finally paints a layer of paint.

Li Zexuan also wants to make this kind of silver mirror. It takes a lot of work to get rid of Nitric Acid. He wants to leave this difficult task to his future students.

As for the key material of the glass mirror - tin foil, the Tang Dynasty already has. Tinfoil foil is a handicraft product unique to Shaoxing in the early years. In ancient times, its main purpose was to use the manufacture to worship the ghosts and gods, which first appeared in the Han Dynasty.

"Can it be like this? Can it really be done?? Young Master ~?"

When I heard Li Zexuan's phrase "a hundred times clearer than the bronze mirror," Uncle Fu was excited and asked quickly.

"Of course, there are some Theory things in it. I don't have time to talk to Uncle Fu, but as long as I do, I will be able to create this high-quality Glass mirror!!"

"haha ~! Good~! old man, let's arrange it, let's arrange it!"

Uncle Fu can't wait, and I plan to go out and bring people to experiment.

Li Zexuan quickly pulled him and said, "Uncle Fu, wait~!"

"What's wrong~!"

Li Zexuan said seriously: "Mercury is extremely volatile. Once inhaled into the lungs, it will definitely cause poisoning. If Workshop wants to make a Glass mirror with this method, you must first solve this safety problem! This way, you can make a special sewing. The mask, add a few layers of toner inside the mask, and then use a thick cloth to separate, the thicker the better! Those who participate in the manufacture of Glass mirrors must wear this special mask."

Uncle Fu is strange: "Young Master, can't you use the mask before? Why bother?"

"Of course not! ~ You must use this mask~! Uncle Fu, you listen to me~!"

Li Zexuan is convinced.

Ordinary masks are only anti-particles, which is what we usually call dust, but mercury vapors are toxic and harmful gases, so it is necessary to wear protective tools that contain filtering devices. If it is not enough, Li Zexuan wants people to Do a gas mask!

"Yes~! Young Master ~! That old man is going to arrange these things now~!"

Uncle Fu is helpless and can only act according to words.

"Well~! Uncle Fu, go get busy~! Dang! After the Editorial Department, turn around~!"

Li Zexuan thought about it and went out with Uncle Fu.

For this batch of glass, if you want to sell a good price, the necessary publicity is essential, so he has to let Ma Zhou design the advertisement in advance.

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