The process flow of filigree process can be mainly divided into the following steps, namely design, production of tire type, filigree production, black tire inspection, cleaning, silver blue, surface treatment (gold plating, silver plating, copper plating), assembly of stone inserts, inspection and packaging and other steps.

Because the training course is only a basic introduction, the content will be relatively simplified, and the teacher will use a stylized template to teach, and the case at the beginning will not be too difficult, just a pair of moire earrings.

So even if other students have made progress, they can already keep up with everyone's train of thought after watching the teacher's teaching video twice in a month.

It just so happened that classes started on Monday.

The students were all filigree on the silver tire, and she looked at it, and the raw material silver bars provided by the teacher were originally slender enough, and she didn't even need to smelt them, nor did she need a sheeter. She only needs to anneal a few more times to make the silver wire softer, and draw the wire through the drawing hole.

There are many different sizes of brushed holes, which means that this can be made of silver wires of different thicknesses, and the thinnest brushed holes can reach 0.15 mm, which is really as thin as a hair!

However, in order to facilitate the pulling, the teacher instructed her to add lubricant to the eye holes, so that her operation would be much easier.

Although it was a little difficult at first, with many pulls, from large eye holes to small eye holes, when the silver wire was pulled to 0.1 cm, the teacher stopped.

The next step is to rub the silk, Lian Yue recalled the video he had seen before, and carefully observed the teacher's on-site demonstration, learned to pick up the washboard like that, and rubbed it in the forward direction with two drawn plain silks, and kneaded them into a strand, and the filaments were kneaded.

Rubbing one, Lian Yue took a look, compared with the teacher's evenly patterned filigree, because she was a beginner, the strength of her hands did not grasp well, and the hand rubbing was not so even.

However, she was not discouraged, she carefully looked at the stumbling part of the teacher's rubbing, and picked up two plain threads again and rubbed them like just now, but while making mistakes, she paid attention to the strength and the effect of rubbing.

Not to mention, consciously control the force and direction, and the filigree will be much more even.

After many experiments, the silk in his hand has been kneaded into strands of filament, and it is becoming more and more uniform, and Lianyue is also satisfied with his progress.

"Strike again." After instructing the other students, Teacher Wang saw that she had made a mistake, so he came over and reminded her.

Lian Yue rolled the filigree together, then put it on the soldering table, and began to recede the fire, while the fire burned on the filigree, Lian Yue looked at Mr. Wang who was standing aside from time to time.

Teacher Wang knew that she didn't know how long it was, so she glanced down and saw that the filaments had softened, so she motioned for her to stop.

Because she had copied the pattern of the bottom of the fetus in advance, when she drew it on the silver tire again, she didn't even find it difficult to fall into the moon.

The annealing of the silver tire is slightly softer, and a few strokes in a row outline the auspicious cloud pattern.

Teacher Wang watched from behind him and couldn't help nodding, this student has a foundation, it seems that the rest should not be difficult for her.

Lian Yue pressed the filament on the silver tire, the tip of the tweezers was downward, the silk was straightened first, and the filament was pinched little by little with tweezers according to the drawn moire, and the broken point was cut directly with scissors, and then the action between was repeated.

The action of the filigree is very difficult, to ensure that the silk pinched out changes with the bending and bending of the pattern, and pay attention to the amplitude.

When encountering a bend in a certain place of moire, it takes several adjustments to ensure the direction of the filament.

Not bad!

Teacher Wang walked around the small classroom, where there were 20 students, and Lian Yue sat in the corner, and she walked by several times to see her progress.

Seeing that she had already pinched the wire, Mr. Wang came over again and instructed her to put on the solder.

However, this solder is exquisite, but not all kinds of solder are applicable, solder is a fine gold process used to connect, fix parts of the first pattern parts of the necessary welding materials, generally divided into gold solder and solder.

Because of the different fineness of gold, gold soldering generally uses different formulas according to different colors of gold jewelry. Silver solder, on the other hand, is mixed with copper and zinc in silver, which will also need to be added according to different proportions of silver content.

At this time, it is the old medicine, also known as the eighty percent medicine (with silver content as the standard), which refers to the proportion of silver in the medicine, which is characterized by fire resistance, can withstand repeated welding and burning in the whole process, and is not easy to open welding, so it is generally used for the welding of tires in the first process.

After putting the solder, Lianyue began to weld with a welding torch under the guidance of Mr. Wang, and the welding torch swept over the silver tire coated with solder, and the silver tire began to change color slightly.

Lian Yue held the silver tire with tweezers in one hand, and held the welding torch in the other, welding it back and forth with fire. When the temperature recedes, Lianyue begins to cut the bottom of the fetus along the edge of the filigree embryo, and a finished bottom is completed.

Finally, Lianyue is about to enter the progress of the big guy, and at this time, the fast-moving person has already finished the finished product and began to watch her.

Lian Yue didn't feel nervous, and continued her movements, she also looked at the movements around her in her spare time, and she knew that the next step was to polish.

Pick up the sandpaper, follow the example of others, and polish the bottom of the tire placed on the wooden plank, until the edges are smooth, and use a hammer to knock the shape.

...

Soon, with the attention and reminder of the students on the side, Lianyue's work was completed.

Although it is only two small auspicious cloud earrings, she did make them step by step, and it is very satisfying to watch.

"You're doing a good job!" A female student saw that the speed was very fast, faster than some of the old students, and she stepped forward and said.

Lian Yue looked up, it looked like a twenty-one or twelve-year-old girl, she looked a little familiar, but Lian Yue rummaged through the memories of the original owner and didn't remember who she was.

"No, it's all the teachers who are guiding and helping." Lian Yue told the truth, although she made the slowest progress, but the teacher helped the most.

Besides, she doesn't want other students to be as "ambitious", and has already begun to try new design works, so she can naturally catch up with most people's progress.

"I'm Wang Ziran, a new student in this phase, what's your name, why haven't I seen you before?" The girl seemed a little familiar, she leaned close and pushed her shoulder.

Lian Yue couldn't resist her enthusiasm, and shrank in slightly: "My name is Lian Yue, and I couldn't come to my family last week." ”

"That's right, but you're moving fast, and you're catching up with our homework last week! He's very talented. ”

Lian Yue didn't know what to say, just laughed dryly.

"Are you a local? Where to stay? The girl's questioning as if checking the household registration made Lian Yue feel even more uncomfortable.

"Well, not far." She said perfunctorily.

"I live in the north of the city, and I still think that if I can wait for the next subway to go back?" The girl didn't seem to notice her coldness, but she was still very enthusiastic.

As soon as she said it, Lian Yue understood what she meant, this little girl should like to pull an acquaintance to accompany her wherever she goes, just like a little girl even has to go to the toilet when she goes to school.

"I just graduated and haven't looked for a job yet, so I want to make a living from this in the future. Why did you come to study? As she spoke, she looked her up and down, which seemed to mean that you don't look like you just graduated. How did you come up with the idea to learn this?

So welcoming!

Not only does she like to get to the bottom of it, but she even has such a good grasp of the means of exposing herself first and then getting closer to you to ask you, this girl's popularity must be very good!

Lian Yue couldn't help but slander in her heart, but she didn't notice that as she finished this process, it was close to noon, and as soon as Teacher Wang said it, many people were ready to eat.

"Lianyue, do you want to go together? I know there's a dry pot nearby that's particularly delicious! With a smile on her face, she highly recommended.

"No, you go, I don't like dry pots." Lian Yue didn't want to be with her, so she refused with a clear conscience.

"Don't like dry pans? So what do you want to eat? Chinese or pasta? I remember that there was a seafood rice shop at the intersection in front of me that was particularly delicious, and their specialty lo mein was also good. Wang Ziran suggested with a serious face.

Lian Yue: ...
