"That's right, Fauber! How many glass utensils have you made before? ”

Just as Fu Bo was about to go out to organize people, Li Zexuan suddenly asked.

Previously, the workshop developed glass, mainly for use on the front cover of the compass, and later with the large fleet to the south, the demand for the compass also declined, but the glass cave can not be idle, Li Zexuan instructed the workers to continue to produce all kinds of glasses and other glassware, although the output is not very high, but it has been accumulated for so long, it must be a lot.

This thing is a huge profit~!

If the cement can't be made, sell this batch of glassware, maybe you can slow down the urgent need~!

"Young Master~! You can finally remember~! ”

Fu Bo was stunned for a moment, and then said with a bitter face: "According to your orders, the glazed kiln of the workshop continued to produce, and until now, those glassware have been piled up in a room!" Not to mention that there are more than a thousand pieces~! ”

Speaking of this, a hint of complexity flashed in Fauber's expression, before this, for all of them, glass is a high luxury, if there is a glass cup, it is not offered as a treasure? But now, the glass utensils in the workshop have been flooded, all of them are like garbage, piled up in the warehouse, and the world is really changing too fast~!

"Hehe~! That's just right~! Fubo, you will arrange a group of people to package this batch of glass utensils in a while, the more exquisite the packaging, the better! I'm going to sell them for a good price recently~! ”

Li Zexuan said excitedly.

He knows the truth that scarcity is expensive, and if he takes out so much glass at once, the average price must be lower, but he can't wait anymore, he needs a lot of money.

"Yes, young master~!"

Fauber also breathed a sigh of relief and arched his hand.

"Hmm~! That's not enough~! Fu Bo, I also have a way to make glass mirrors here, the process is very simple, you let people make fifty sides first~! ”

Li Zexuan roughly calculated that these more than 1,000 pieces of glassware, under the best circumstances, could only be sold for 50,000 or 60,000 yuan, so he thought of a very important derivative of glass - mirrors.

I believe that as long as it is a rich lady, she can't resist such a charm, and naturally it will be more profitable.

"Oh~? Master, you say~! The old man remembered. ”

Fauber's eyes lit up and he hurriedly said.

"Hehe~! This one is very simple, Fuber you have someone to stick tin foil on the side of the glass, and then pour mercury on it. The tin foil will dissolve in mercury and turn into a silvery-white liquid, which is tightly attached to the glass plate, so that it will become a glass mirror that is 100 times clearer than the copper 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 to a smooth and smooth finish. The figure reflected in this bronze mirror is not bright. It also rusts and must be polished frequently.

More than 1,700 years ago, glass mirrors were born. The original method of making glass mirrors was to attach a piece of tin foil tightly to the glass, and then pour mercury, because the mercury can contain the tin and turn it into a viscous silvery-white liquid - tin amalgamation, which is tightly attached to the glass plate. The glass mirror was a big step forward from the bronze mirror, and it was very popular, and for a time it became a treasure that the princes and nobles competed to buy.

At that time, only the Venetian workshops could make this new type of glass mirror, and all the countries of Europe went to buy it, and wealth poured into Venice like a tidal wave. The Mirror Workshop was concentrated on the island of Murano, surrounded by sentry posts and tightly sealed. Later, the French government bribed four Venetian mirror craftsmen with a large sum of money and secretly smuggled them out of the country. Since then, the mystery of the mercury glass mirror has been revealed, and its value is not so noble.

However, the ability of mercury-coated mirrors to reflect light was not very strong, it was time-consuming to make, and mercury was 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 or electroplated, it is coated by a chemical "silver mirror reaction". Add glucose water to the ammonia solution of silver nitrate, and the glucose reduces the silver ions into silver particles, which are deposited on the glass to make a silver mirror, and finally brushed with a layer of lacquer.

Li Zexuan also wants to engage in this kind of silver mirror, but it still takes a lot of work to get rid of nitric acid, and he wants to leave this arduous task to his future students.

As for the key material of glass mirrors - tin foil, the Tang Dynasty already had it. Tin foil is a kind of handicraft product unique to Shaoxing in the early years, and its main use in ancient times was to make money to worship ghosts and gods, which first appeared in the Han Dynasty.

"How can it be like this~? Can it really be done~? Master~? ”

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

"Of course you can, I don't have time to talk to you about some of the principled things in this, but as long as you do what I say, you will definitely be able to create this high-quality glass mirror~!"

"Haha~! Good, good~! Decay will arrange it, this will arrange it! ”

Fauber was a little impatient, and planned to go out and take people to do experiments.

Li Zexuan hurriedly grabbed him and said, "Fu Bo, wait~!" ”

"What's wrong~!"

Li Zexuan said solemnly: "Mercury is very volatile, once inhaled into the lungs, it will definitely poison people, if the workshop wants to use this method to make a glass mirror, it must first solve this safety problem!" In this way, you have people sew a batch of special masks, add several layers of toner to the masks, and then separate them with a coarse cloth, the thicker the better! Those involved in the manufacture of glass mirrors must wear this special mask. ”

Fu Bo said strangely: "Young master, can't you just use the mask you used before?" Why bother~? ”

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

Li Zexuan said categorically.

Ordinary masks are only anti-particle, which is what we usually call dust, but mercury vapor is a toxic and harmful gas, so it is necessary to wear the kind of protective tools that include a filter device.

"Yes~! Master~! Then the old man will go and arrange these things now~! ”

Fauber had no choice but to act according to his words.

"Hmm~! Fubo, go get busy~! I'll go to the editorial office of the back office~! ”

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

If this batch of glass wants to be sold at a good price, the necessary publicity is indispensable, so he had to ask Ma Zhou to design the advertisement in advance.

At this time, the superiority of "Datang Daily" is fully reflected! Feel free to advertise yourself!
