"The butterfly cup heirloom is hard to buy, and the colorful butterflies in the wine cup are flying." Fan Wuxi held a glass in his hand, and asked He Shuisheng with some curiosity, "This is the butterfly cup that can appear with the shadow of a butterfly?" ”

"That's right, this is our factory's unique technology, butterfly cup!" He Shuisheng said proudly.

In the traditional Chinese Pu Opera, Qin Dialect, Peking Opera, Hebei Bangzi and other operas, there is a widely circulated repertoire "Butterfly Cup", which describes a love story that occurred in the Ming Dynasty. The love between men and women in the play is the heirloom of the man's family - the butterfly cup.

It is said that when you pour wine in this wine glass, you can see a colorful butterfly rising from the bottom of the glass, rising and falling between the flowers, lifelike, fascinating, the glass of wine is drunk, and the colorful butterfly is gone.

I saw the wine glass that Fan Wuxi was holding, a tall cup with a thin waist and wide feet, like a jade-colored wine cup with a reverse mouth, and the rim of the cup was inlaid with gold, which was dazzling; The outer wall is full of dragons playing with pearls, colorful; Tingting flowers on the inner wall, enchanting and beautiful, He Shuisheng took a water bottle, and poured water into the cup in front of Fan Wuxian and Fan Heng, only to see a butterfly shadow on the water surface really fluttered, lifelike, rippling with the water surface.

"Huh! Funny—" both father and son shouted excitedly.

Fan Wuxi's first feeling was that if this thing was taken abroad, it was estimated that he could cheat a lot of money.

"Butterfly cups have long been recorded in the history of our country, and their production process has long been lost. In recent years, workers and technicians in Panshi City have obtained a bottle of ancestral butterfly cups from the people. After careful research and in-depth excavation, we finally figured out the optical principle of the ancient artist's skillful cup full of butterflies and the hidden butterflies of wine. From more than 10,000 species of butterflies in the world, the most beautiful species were selected to be painted and painted, and finally the ancient treasure cup was reproduced in the world. He Shuisheng sighed beside him.

Fan Wuxian took the cup and watched it carefully, and it didn't take long to discover the mystery.

In the past, the ancient butterfly cup was made of porcelain, and all the secrets were hidden in the cup legs that could not be seen, and it was naturally difficult for outsiders to understand the mystery, but now this cup is made of glass, and it is easy to find its principle under careful observation.

The technician attaches a butterfly to a thin spring hairspring in the foot of the cup, and as long as the cup is disturbed slightly, the butterfly will bounce. A bead is embedded in the center of the bottom of the cup, which acts as a convex lens.

When there is no alcohol in the glass, the position of the butterfly is outside the focal point, and it is on the same side as the human eye through the real image formed by the convex lens, and the human eye is generally unable to see clearly. When the wine is poured into the glass, the cross-section of the wine is thin in the middle and thick on the side, so that the wine becomes a concave lens. The convex lens and the concave lens are combined to form a compound lens, which elongates the focal length so that a clear butterfly pattern can be seen at the bottom of the cup.

"Sure enough, the cup is full of butterflies, the wine is dry and the butterflies are hidden, and the ancients' use of optical principles is not worse than ours at all!" Fan Wuxian couldn't help but admire.

Fan Wuxi poured some more water into it, held it in his hand to look at the butterfly shadow, and suddenly had an idea.

"What would happen if you put this in the humidifier's tank?" Fan Wuxian rubbed the outer wall of the cup and thought about it seriously.

After some investigation, Fan Wuzhi felt that Panshi Glass Factory was still capable of accepting orders for external humidifier equipment, and the most important thing now was to come up with a few more perfect sample design drawings.

As a glass device with practical functions, it must be produced in large quantities while satisfying the aesthetics, so Fan Wuzhi did not dare to hold it up, lest his design would be too complex to be mass-produced, so he communicated his thoughts with Fan Heng, and finally decided to see if the glass factory had satisfactory design capabilities.

"Director He, regarding the style of glassware, we have a few preliminary ideas here, I don't know if it can be realized by your factory?" Fan Heng asked He Shuisheng for advice.

This is to study our technical ability, after He Shuisheng heard it, not only did he not feel embarrassed, but felt that this time it was really a big deal, so he patted his chest and said, "Director Fan, but please rest assured!" We still have a few top-notch talents here, and there are many masters, but everything that can be made into glass, there should be no problem, but I don't know if you have sketches? ”

"Sketch-" Fan Heng glanced at Fan Wuxian and said to He Shuisheng, "It's going to be there soon!" ”

Fan Wuxi was not idle, first drew a few ordinary patterns and handed them to He Shuisheng, and then began to think about the problem of loading the butterfly cup process onto the glass water tank of the humidifier, and finally came up with a final draft.

On a large lotus leaf-shaped glassware, coiled with several dragonflies, the bottom is the use of butterfly cup technology, to make a small picture scroll, after adding water, because the water continues to flow downward, and the ceramic oscillator continues to blow up the water mist, the water surface has been rippling, so that the scenery on the picture will always be projected on the water surface to move.

"It's a little more complicated, but it's not impossible, but the cost is much higher." Although He Shuisheng is engaged in reception work, he is familiar with the situation of his own factory, and after reading Fan Wuxi's sketches, he immediately has a plan.

Fan Wuxian also knew that it would take a while for this thing to be realized, and just adjusting the focal length would require the workers to explore for a while, so he agreed, "This is a test paper, and if we do a good job, we can talk about specific things in depth." However, I think your company's technical force is still relatively strong, and I personally agree with your factory's opinions. ”

"Hehe, that's a good dare!" He Shuisheng accompanied the smiling face, but said in his heart Who is this young man? Looking at his appearance, he looks a little like Fan Heng! It's just that he didn't think that they were originally two fathers and sons.

That is, while speaking, a master walked over with a few apprentices, holding a few glassware drawn by Fang Cai Fan Wuxi.

"Look, isn't it very fast-" He Shuisheng laughed, and introduced the master to the Fan family father and son, "This is the master of our factory, Master Li Deyi Li, he is an old man when our factory was built, there is no technical point to say, it is an absolute master!" ”

"It turned out to be Master Li, and I am fortunate to meet him." Fan Wuxian looked at Master Li while looking at the glassware that had just been made, and found that it was impeccable in terms of shape and quality, and it had completely reached the level of handicrafts, and he couldn't help but admire, "He deserves to be a famous teacher!" Looking at such a perfect work of art, I can't even find words to praise it! ”

The old master smiled, he didn't take Fan Wuxi's words to heart, he had received so many good words in his life, where would he care about the praise of a half-year-old son? There is no need to worry about whether his products will be popular, the only thing that makes him unhappy is that the factory's orders are too simple.

"The one with the butterfly cup process will not be made until tomorrow, because there are some technical parameters that need to be measured, so you won't be able to see it today-" Master Li said to the crowd.

Oh, Fan Wuxi nodded, turned his head and asked, "That thing, can it also be mass-produced?" If the process is too complex, will it lead to inefficient production? If the speed can't come up, then there is no value in putting it into production. ”

He Shuisheng is a little worried, if the output is low, everything will be blind, people have to order in large quantities, you are like a work of art to go out three or five pieces, who can stand it?

Master Li glanced at the eager He Shuisheng, and replied confidently, "No problem, it's just that you need to measure the parameters at the beginning, and it takes a little more time, and it won't be in the future, and you can produce it on time." ”

"That's good, that's good!" Fan Heng also considered this problem, but he didn't expect his son to mention it first, and at this time, he got an affirmative answer from Master Li, and he also had a bottom in his heart, so he nodded again and again.

Because the humidifier is indeed a good thing, Fan Heng also very much hopes to be able to do this, at this time the core components have been settled, the box separation technology has also been realized, seeing that the aristocratic humidifier advocated by Fan Wuzhi is also about to succeed, Fan Heng's heart is still relatively happy.

Although he was a little worried about Fan Wuxi's vigorous grabbing of huge profits, Fan Heng's mood was much better when he thought that these things might go abroad to earn foreign exchange in the future. Making money from foreign devils is naturally more refreshing!

After the father and son followed He Shuisheng to a few more places, they took their leave.

After watching the two people leave, He Shuisheng hurriedly ran back to the office, brushed and wrote a report, and after looking at it, he felt that he was not satisfied with his words, so he said to a young man next to him, "Xiao Wang, copy this in two copies, no, three copies!" Remember to use it tomorrow! ”

After finishing speaking, he walked out of the office humming a little tune, He Shuisheng thought to himself, no matter whether this business is successful or not, it is finally my performance today! When the time comes, in front of the factory director and secretary, there will still be merit to be placed!
