After eating and resting for a while, Liu Yuan took Ah Zhong, Ah Yi and Xiaoqing to his dedicated studio.

This is the first time that the three little guys have come to Liu Yuan's studio, because usually, they are not allowed to enter here, because this is for the exclusive use of the young master.

As soon as they entered it, the three of them couldn't help but exclaim, only to see that the studio was very neat and clean, it can be said that it was spotless, in addition to being clean, the second impression was that there were a lot of tools here, and it was estimated that there were dozens of them, all the tools were neatly arranged, that is, the direction, all of them were the same, just like the team, except for the tools, like those original materials, like gold, silver, gemstones, turquoise, paraffin and other things of different colors, all lined up very neatly.

When everyone remembered that after completing the task every day, they threw away the tools at will, and compared with the young master, their faces were really red.

Xiaoqing stuck out her tongue and said in surprise: "Young master, you have so many tools here, do you need so many tools to make jewelry?" ”

Liu Yuan shook his head and said, "Is it too much?" Here is less, different practices, need different tools, to learn well, you have to work hard, you don't look at so many knives here, in fact, the principle is the same, is how to do, in order to make your work more perfect, take this carving knife as an example, I here half a knife, a knife, two knife, five knife, round knife, scimitar, chamfering knife, flat knife, sharp cone knife, left and right oblique knife, etc., you usually shovel copper plates, with just the most ordinary flat-headed knife and yourself, just learn a knife every day, and learn a little more in the future. ”

When the three little ones heard this, they all had a feeling of jumping out of the fire pit and having a headache.

It's so miserable to learn a knife, there are dozens of them here, how to learn it~~~~

Liu Yuan ignored their reactions and continued to explain: "A piece of jewelry is divided into multiple processes, such as hammering, casting, welding, cutting, polishing, riveting, plating, engraving, hollowing and other processes, each process is an important component, as long as there is a process that is not done well, it is not a perfect work, but" Liu Yuan changed his voice and said: "You don't have to learn so much, I decided to learn a few processes per person according to your characteristics, and in the future, you only need to do your own few processes." ”

Ah Zhong and they breathed a sigh of relief, they only learned a few things, if they learned them all, it would be really big.

"Young Master, shall we study today? There are so many tools here, which one do we learn first? Xiaoqing said timidly.

The eyes of the three of them are a little expectant, to be honest, they like and like to learn a little more, because they understand: they are just a slave, a useless slave, they are not welcome anywhere, only if they learn well, the master thinks that you are useful, your position will be stable, and you will not sell yourself or transfer it to others at will.

It's so good here, it's good to eat and sleep, and the host treats them very well, so a fool is willing to leave here.

Liu Yuan smiled, stretched out a finger and shook it, "Don't worry, we won't practice swordsmanship today." ”

"Then~~ Master, what are we doing?" Ayi asked curiously.

"This question is well said" Liu Yuan said with a smile: "If you want to do a good thing, then you must have a detailed understanding of it, don't take it to make jewelry, don't think it's so simple to knock and beat, before you build jewelry, you have to understand these materials, know their characteristics, first of all, you have to think about how to match to look good, how much is the material you use to make a piece of jewelry worth, how much time it takes from the beginning to the completion of the building, how much money can you sell after the jewelry is made, and how much jewelry similar to it is sold by others, etc." ”

The three little ones nodded their heads as if they didn't understand.

Do jewelry, when the real gold and fake gold are not clear, the material is also half-understood, when the time to make a problem to others do not know the way, Liu Yuan knows the way, sharpen the knife and do not break the firewood worker by mistake, these three little guys, most of them are poor and sold as slaves, not to mention silver, it is estimated that they have not even touched the silver a few times, Liu Yuan decided to popularize their basic knowledge first.

"Alright, you three sit down, I'm going to enlighten you now."

When Ah Zhong, Ah Yi, and Xiao Qing heard this, they hurriedly sat up, and waited respectfully for Liu Yuan's teaching like primary school students, and Xiao Niang also slipped in at some point, sat down with a small bench, and looked at Liu Yuan with interest.

It's really naughty~~

However, Liu Yuan just smiled at her, didn't say anything, and immediately started his training plan.

Just watch it if you want, there's nothing to hide.

"To make jewelry, there is one thing that is indispensable, and that is gold" Liu Yuan took out a gold ingot and raised it in front of everyone, threw it a few more times, and then continued:

"Gold, and divided into raw gold and cooked gold, raw gold is also called natural gold, waste gold, raw gold, is the object of cooked gold, is from the mine or river bottom alluvium mining without melting and refining gold, raw gold is mainly divided into mineral gold and sand gold two kinds, mineral gold, also known as synthetic gold, produced in mines, gold mines, most of them are precipitated with the hot springs gushing out of the ground through the cracks of the rock; Sand gold, on the other hand, is produced at the bottom of rivers or low-lying areas, mixed with stone and sand, and washed out. Sand gold originated in mines. Because the gold ore is exposed to the ground, after a long period of wind and rain, the rock is weathered and cracked, and the gold will be separated from the vein and accompanied by sediment and go down the water, naturally precipitated in the stone sand, and deposited as a gold-bearing layer at the bottom of the river or under the sand and gravel, thus forming sand gold. ”

Liu Yuan then explained: "Of course, I don't mean to let you go to the wild to dig for gold or go to the river to pan for gold, but just to let you understand. We make jewelry, all we use, are cooked gold, the so-called cooked gold, is the smelted gold, test you a question, do you know what a lot of people receive gold, do you like to bite it with your teeth? ”

"That, I'm happy, young master, if I get hit, I'll bite it too." Ah Zhong said whimsically.

Xiaoqing thought for a while and said, "Young master, is that person thinking that he is dreaming and is reluctant to slap himself, so take a bite and see if it is a dream?" ”

"It's habit, isn't it?"

The three little guys, you say a word, I express my opinion one word, and Liu Yuan listened with a smile on the side.

It's no wonder that gold is not circulating now, and everyone is holding on to a little gold, and these three little guys haven't touched gold a few times, which is also reasonable.

"Little lady, you grew up in a gold shop, you tell them." Liu Yuan gave this opportunity to Xiao Niang.

"Yes, senior brother~~" The current little lady can say a hundred things to Liu Yuan, and nodded and agreed.

As the "child" of the gold store, the shopkeeper Yuan has not passed on this knowledge to Xiao Niang, so Xiao Niang can also be called an expert figure in this regard.

"That's the case, the better the gold, the softer the hardness, the better the gold, with the nails can make shallow marks, the teeth bite can leave tooth marks, with a bite, I don't know if the piece is gold, what is the fineness of the gold, this is the simplest and most direct detection party

Law. ”

Ah Zhong and the others looked suddenly enlightened, it turned out to be like this.

Liu Yuan smiled and added: "To test the fineness of gold, in addition to testing its hardness, there are four more commonly used methods of looking, checking, listening, and burning. ”

"Look, it's the color, the higher the purity of the gold, the darker the color. In the absence of contrast, the general fineness can be determined according to the following colors (based on lapis gold. The so-called lapis gold contains only silver in it); The dark red yellow color is more than ninety into five, the light red yellow is between ninety and ninety, the light yellow is eighty to eighty into five, the blue-yellow is six into five to seventy, the color blue with white light is only five to sixty, and the yellowish and white is less than fifty, and the commonly said seven green, eight yellow, and nine red can be used as a reference. ”

"Weigh the weight, the same size of gold, much heavier than silver, copper, lead, etc., should have a sinking feeling in the hand, and the fake one feels light"

"Listen, is to listen to the sound, more than ninety percent of the real gold thrown on the hard ground, will make a "horn" sound, there is no rhyme and no elasticity. Fake or low-quality gold has a brittle and non-dull sound, generally makes a "dangdang" sound, and the sound has an aftersound, and beats violently after landing. ”

"Burning, that is, burning with fire, real gold is not afraid of the fire of the red furnace, after burning and cooling, if the surface is still the original gold color, it is pure gold; If the color is darkened or darkened to varying degrees, it is not pure gold. Generally, the lower the color, the stronger the color, and all black, it is a fake. ”

Seeing that Ah Zhong, Ah Yi and Xiao Qing looked a little out of the clouds, it was estimated that it would be difficult to digest so much content for a while, Liu Yuan took out the things that had been prepared in the morning, and said while taking them: "You see, I have already prepared, here are ten pieces of gold of the same size, but of different purity, from one percent to ninety percent, I have made marks on it, you can compare, and then there are silver, copper, iron, and other metals, feel it yourself, explore more, okay, today's content is this, Look at it. ”

Before going out, Liu Yuan turned his head again and said: "The things here can only be seen, not touched, they are broken, be careful that I dismantle your bones." ”

"Yes, young master."

"Young master, I know the way."

Ah Zhong, they agreed again and again.

Liu Yuan smiled and pulled the little lady out of the house.
