Li An took a closer look, after the wall dried, the place where it had been wiped had turned white, it was not different from the surrounding white, there was no difference at all, you had to look very carefully close to find the slightest difference, if you were reliable too close, your eyes would soon be unbearable, and ordinary people would not be idle, lying on the wall to find flaws, wouldn't that be self-inflicted.

In short, the melamine coating experiment has been a great success, Li An spent so much effort is not in vain, only need to optimize it slightly, melamine paint can be put into production, when the time comes, the north twenty miles will add another workshop, from the current lime workshop, cement workshop, plus a melamine paint workshop, so as to form a larger industrial group, help optimize resources, and promote the faster and better development of Anzhu City.

The more workshops there are, the more craftsmen will be needed, the population will grow faster, and prosperity will naturally come sooner, which will definitely be a great thing for Anzhu City.

"Well, yes, as the official expected, this melamine paint can be mass-produced, and it will be built next to the cement factory, and it will be about the same at an interval of a hundred steps."

Ang Lee made a satisfactory decision.

"Yes, my subordinates will arrange it."

The subordinates answered and immediately went to make arrangements.

"Look at this wall, it's exactly the same when it's dry, and you can't see any difference from the previous one, it's amazing."

"This melamine paint is really good, not only can make the room brighter, but also not afraid of washing, dirty can be wiped with a damp cloth, great."

"The shop I rented has not yet painted the walls, so I use this material, but I don't know when this melamine paint will be used."

"Our Datang is just amazing, even such a powerful thing can be made, it's really amazing, these small foreign countries can't make these things."

"It's not all the credit of Li Shilang, if it weren't for Li Shilang, where would Datang be able to make so many powerful things."

While praising the melamine coating, the businessmen did not forget to compliment Li An, which made Li An very happy.

Li An saw a merchant holding a magnifying glass, carefully observing the wall that had just been wiped with a damp cloth, and his appearance was too serious, as if he was studying antiques, for fear of making a mistake.

This magnifying glass was also invented by Ang Lee, and it was sold in ordinary stores in Chang'an City in the Tang Dynasty, and some merchants even exported this product overseas, so that overseas people could also have such an item.

Businessmen are the least bad people in this era, and once people have money, they will like these strange gadgets, especially the magnifying glass these gadgets, which are very practical things, businessmen are very fond of it, as long as they meet, they must be willing to buy a play, and the magnifying glass is indeed very practical, in broad daylight, it can be used to light the fire, some small things can not be seen, you can also use a magnifying glass to see, such as the ledger or something, you can use a magnifying glass to observe.

However, the magnifying glass is Ang Lee's own unique industry, and the ex-factory price in Chang'an City is dozens of times the cost, which can be described as an absolute profiteering, and such a product is sold overseas, and the price must be increased many times on the basis of the retail price of shops in Chang'an City, otherwise, the businessman will be busy in vain.

That is to say, the magnifying glass, which was originally very low-cost, became a luxury item after it arrived overseas, and only the wealthy merchant class and the official class could have it, and the ordinary working masses did not have the strength to buy this kind of product, just like diamonds, which were not played by ordinary people, and ordinary people could only buy a set when they got married.

From the posture of the merchant holding the magnifying glass, you can see how much he attaches importance to this thing, and the handle of this magnifying glass seems to have been modified, a hole has been dug in the middle, and a thread is pierced, and the thread is hung on the merchant's hand and neck, so that even if the magnifying glass is accidentally taken off, it will not fall to the ground, but will be pulled by the rope, so as to avoid the fate of being broken.

This shows that the merchant treats the magnifying glass as a treasure, for fear that the magnifying glass will be damaged or stolen.

"Where did I buy this magnifying glass and how much did it cost?"

Li An walked up to the merchant and asked.

"Oh, Squire Lee." The merchant paused for a moment, and then said, "This is a friend who brought me from Chang'an City, a hundred gold coins." ”

"A hundred gold coins?" Li An smiled at the corner of his mouth and said, "Don't you think it's expensive to spend so much money on such a gadget?" ”

"It's not expensive, it's only a hundred gold coins, and in the store in West Tianzhu, this one can sell for one hundred and fifty gold coins."

The merchant carefully took the magnifying glass in his hand and said seriously.

Li An smiled at the corner of his mouth, and sighed that the merchant's heart was black, such an ordinary small commodity, the price had actually increased so much, of course, his own heart was also quite black, he could increase the price dozens of times when he left the factory, so the businessman would be able to increase the purchase price of the commodity overseas dozens of times.

The premise that the price of goods can be doubled casually is that things must be good enough, and at the same time, they must be in short supply, in the era of Datang, because of the poor flow of traffic and information, it is normal for supply to exceed demand, and Li Ang also deliberately limited the output of these commodities to prevent the result of oversupply, resulting in a backlog of their own products.

In addition, Datang's scientific and technological level is still backward in general, and in order to prevent the leakage of technology, Ang Li recruited a small number of craftsmen, so it is impossible to increase the output to too much, which causes an inevitable shortage of supply.

"In Chang'an City, this magnifying glass is worth a maximum of ten gold coins, but I didn't expect that in Xitianzhu, it was actually sold for a high price of one hundred and fifty gold coins, an increase of fifteen times! This is all due to the poor traffic, when the railway is repaired, the goods of Chang'an City can directly reach Anzhu City by railway, the circulation cost will be greatly reduced, and the price of these gadgets will be greatly reduced. ”

Li An said with a sigh.

"What, it's only ten gold coins in Chang'an City."

The merchant's face changed slightly, it was obvious that his friend didn't tell him that, but the price that his friend sold him was much cheaper than that of Xi Tianzhu, so he didn't suffer a loss, after all, if he went to Datang in person, the round-trip fare would be too high, and the purchase price from the West Tianzhu shop was even more expensive, so it could be regarded as a friendship price.

"All the magnifying glasses in the world are the property of the official, and they are also designed and produced by the official himself, so the official knows the price of the commodity best, and in addition, the wooden handle of the magnifying glass designed by the official has no small holes or tied lines, this is your own modification!"

Ang Lee said with a smile.

"What Li Shilang said is that this magnifying glass was bought for 100 gold coins after all, and this thing is very afraid of falling, and I am afraid that it will be broken, so I asked the craftsman to drill a small hole in the wooden handle and tie it up with a thin rope, so that it will not be broken."

The merchant spoke.

"You've got a lot of brains! If this one falls, a hundred gold coins will be lost, haha! ”

Ang Lee said with a smile.

Magnifying glasses have become a luxury in this era, and they are still fragile luxuries, and if they are accidentally broken, they will become worthless.

In this era, gold and silver are not easy to break, but jade, antiques, and glass products that appear now are very easy to break, and you must be very careful when using them, because if you are not careful, you will break the fortune, so this merchant is a cautious person, and at first glance it is difficult to lose himself, and at the same time it is difficult to make a fortune.

"Li Shilang, this magnifying glass is a good thing, some things can only be seen clearly with the help of this magnifying glass, such as this wall, the place that has been wiped and the place that has not been wiped, it is difficult to see the difference directly at all, but through the magnifying glass, the difference is relatively big, very obvious."

The merchant said.

"Oh, do you see the difference?"

Ang Lee asked.

"Where it hasn't been wiped with a damp cloth, the walls have a lot of fine lines, and it's very uniform, while where it's just been wiped, the walls have very few fine lines, and it's very uneven."

The merchant replied earnestly, seemingly very satisfied with his observations.

"Oh, is it? Come, let the officer see. ”

Li An was also curious in his heart, and reached out to ask for a magnifying glass, wanting to take a look in person to see if what the merchant said was true.

"Li Shilang, you have taken it."

The merchant didn't seem to be at ease with Ang Lee, so he carefully untied the rope of the magnifying glass from his hand and wrapped it around Ang Lee's arm to prevent Ang Lee from accidentally breaking the magnifying glass.

"You're too careful, I'm afraid that the official will smash your baby, like this magnifying glass, there are many more on the official's ship, but they are generally not used, so they won't be carried with you."

Li An glanced at the merchant with disdain, then picked up a magnifying glass and carefully observed the wall to see what the difference was between a wall that had been wiped with a damp cloth and a wall that had not been wiped with a damp cloth.

Although the white walls were dazzling, in order to prove that what the merchant said was true, Ang Lee could only endure the discomfort and insisted on carefully examining the subtle differences between different parts of the wall.

After some careful observation, Li An soon discovered that the merchant was telling the truth, and the places that had been wiped with a wet cloth were indeed very different from those that had not been wiped with a wet cloth, and the stripes on the walls were different.

Where it has not been wiped with a damp cloth, the streaks are very strong, just like a matte surface, and where it has been wiped with a damp cloth, the streaks are very weak, and even, the streaks are not visible at all, and it looks a little smooth.

"That's right, you're right, it's really like this, you're very careful!"

Li An smiled and returned the magnifying glass to the merchant, so as not to hold it in his hand for too long, and the merchant was worried.

After the merchant took the magnifying glass, he carefully put it in his pocket, for fear that someone would borrow it and break it, so the loss would be great, and many of the people on the scene were his peers, so it was always inappropriate for people to lose money.

"There's still some difference between wiping it down, but who cares about those details? As long as the whole room is bright and there are no visible stains on the walls, it is enough, a few blemishes, completely bearable. ”

Ang Lee said with a smile.

The merchants nodded in agreement, agreeing with Ang Lee's words, they are all businessmen, and no one cares about the nuances of the walls.

Some businesses that have already laid wooden planks on the walls are thinking about how to apply a smooth layer of melamine paint to the wooden boards to increase the brightness of the store, not only to make the customers comfortable, but also to the people working in the store.

After looking at the melamine coating, Li An returned to his residence, carefully sorted out the data of his experiments a few days ago, and then called a few craftsmen with better skills and reliable people, and handed over these experimental data to them respectively, so that each of them could master the technology of one of the ingredients, so as to keep it confidential to the greatest extent, of course, because the melamine paint is not the core technology of the Tang Empire, so even if it is leaked, it is not too much concern, at most it is just a loss of some economic benefits.

On the map, the location of the lime mine, northwest of the cement mill, and due east of the lime mine, there is a large open space, which is very suitable for the construction of the workshop, and Lee Ang intends to build a new melamine paint workshop here.

In this way, the three workshops are in the shape of a zigzag, if the three workshops are regarded as a whole, among them, the lime mine is in the northwest direction, the cement workshop is in the south direction, and the melamine paint workshop is in the northeast direction, such a zigzag configuration is most suitable for concentrating manpower and material resources, which is very advantageous.

"A few of you remember, the technology that the official handed over to you is the guy you will eat in the future, but you must keep it a secret, you can't disclose the technology you have at will, and you are not allowed to ask each other blindly, do you understand?"

Li An admonished solemnly.

"Li Shilang, don't worry, how dare the little one leak it."

The six craftsmen nodded in response.

"The task of building a melamine paint workshop is entrusted to you, and the six of them are also under your control, and they must be able to produce qualified products within half a month."

Li An looked at one of his subordinates and asked.

"Yes, my subordinates understand."

The subordinate answered.

After getting the melamine paint workshop, Li An asked his subordinates to leave and immediately went to prepare for the construction of the workshop, and he had to take a break, sorted out so many materials, and spent a lot of time explaining, Li An was tired for more than three hours, and he was really tired.

And the most effective way to relieve fatigue is not to lie down and sleep, but to let the little beauty massage herself, this way of relaxation is the most correct way, and it is also the most able to make people really relax and relieve fatigue, at least, Li Ang thinks so, and it is the conclusion reached after practice.
