"By the way, Uncle Fu! How many glass utensils have you made before?"

Just when Uncle Fu was about to go out to organize people, Li Zexuan suddenly asked.

In the past, 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 slumped, but the glass cave could not be idle. Li Zexuan instructed the workers to continue producing various Although the output of glass cups and other glassware is not very high, it must have been accumulated for so long.

This thing is huge profits~!

If the cement can't come out, sell this batch of glassware, maybe it will be a relief~!

"Master~! You finally remembered~!"

Uncle Fu was stunned for a moment, then said with a bitter face: "According to your instructions, the workshop's glazed kiln continued to produce, and until now, those glass utensils have filled a room! At least there are more than a thousand pieces~! "

Speaking of this, there was a hint of complexity in Fu Bo's expression. Before that, for all of them, colored glass was a kind of luxury. If a family has a colored glass, it doesn't seem like a treasure. supply? But now, the glazed utensils in the workshop have flooded into a disaster, and they are all piled up in the warehouse like garbage. The world is really changing too fast~!

"Hehe~! That's right~! Fubo, you will arrange a group of people to pack this batch of glazed utensils. The more exquisite the packaging, the better! I will sell them for a good price recently~!"

Li Zexuan said excitedly.

He knows the truth that rare is the most expensive. If you take out so much glass at once, the average price will definitely be lower, but he can't wait any longer. He needs a lot of money.

"Yes, Master~!"

Fubo also breathed a sigh of relief and cupped his hands.

"Well~! That's not enough~! Uncle Fu, I have another way to make a glazed mirror. The process is very simple. You can ask someone to make fifty faces first~!"

Li Zexuan made a rough calculation. In the ideal case, these more than 1,000 pieces of glassware can only be sold for 50,000 to 60,000 pieces, so he thought of a very important derivative of glass—mirrors.

I believe that as long as this thing is a lady from a wealthy family, it can't resist its charm, and naturally it will make more money.

"Oh~? Young master, you said~! Remember this old man."

Fu Bo's eyes lit up and said quickly.

"Hehe~! This is very simple, Fu Bo, you have someone 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 silver-white liquid, and stick it tightly on the glass plate, so that it will 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 has been more than 3,000 years ago, and people used bronze mirrors at first. It was made of bronze cast into a disc and polished so that it was smooth and smooth. The figure reflected by this bronze mirror is not bright. It will also rust and must be polished frequently.

In 1700 AD, the glass mirror was born. The original method of making glass mirrors: first stick a piece of tin foil tightly on the glass, and then pour mercury, because mercury can dissolve tin and turn into a viscous silver-white liquid - tin amalgam, tightly attached to the glass plate. Glass mirrors are a big step forward compared to bronze mirrors, and they are very popular. At one time, they became treasures that princes and nobles compete to buy.

At that time, only a workshop in Venice could make this new type of glass mirror, and all European countries went to buy it, and wealth flowed to Venice like a tide. The Mirror Factory was concentrated on Murano Island, and guards were set up around it, and it was strictly blocked. Later, the French government bought four Venetian mirror craftsmen with a lot of money and secretly smuggled them out of the country. Since then, the mystery of the mercury glass mirror has been made public, and its value has become less noble.

However, mercury-coated mirrors were not very good at reflecting light, time-consuming to manufacture, 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 painted or electroplated, it is applied by chemical "silver mirror reaction". Glucose water is added 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 a layer of paint is applied.

Li Zexuan also wanted to do this kind of silver mirror, but it took a lot of work to get rid of nitric acid. He wanted to leave this arduous task to his future students.

As for the key material of glass mirrors, tin foil, it was already available in the Tang Dynasty. Tin foil paper is a unique handicraft product in 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.

"How can this be done~? Can it really be done~? Young master~?"

Hearing Li Zexuan's words "a hundred times clearer than a bronze mirror", Uncle Fu got excited and asked quickly.

"Of course, I don't have time to discuss some of the fundamental things with you in detail, but as long as you follow what I say, you will be able to create such a high-quality glazed mirror~!"

"Haha~! Alright~! This old man will make arrangements, this will make arrangements!"

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

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

"What's wrong~!"

Li Zexuan said solemnly: "Mercury is very volatile. Once inhaled into the lungs, it will definitely cause poisoning. If the workshop wants to use this method to make glazed mirrors, it must first solve this safety problem! In this way, you can let people sew a batch of them.

Special mask, add several layers of toner inside the mask, and then separate it with coarse cloth, the thicker the better! Those involved in the manufacture of glazed mirrors must wear this special mask. "

Uncle Fu said strangely: "Master, can't you just use the mask from before? Why do you need to do this~?"

"Of course not~! You must use this kind of mask~! Fubo, listen to me~!"

Li Zexuan said categorically.

Ordinary masks are only anti-particulate, which is what we usually call dust, but mercury vapor is a toxic and harmful gas, so it is necessary to wear protective tools that include filtering devices. Gas masks!

"Yes~! Young master~! That old man will go and arrange these things now~!"

Fubo was helpless and could only do what he said.

"Hmm~! Uncle Fu, go get busy~! I'll go to Houya's editorial department to go around~!"

Li Zexuan thought for a while, and went out with Uncle Fu.

In order to sell this batch of glass at a good price, the necessary publicity is essential, 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 anytime!
