"I'm so sleepy, whose chickens are crowing again? Grandma's, I have to steal it and stew it at night! ”

When it was just dawn, Li Tianyuan stretched his waist and walked out of the house, and when he raised his eyes, he saw Qin Feng and Xie Xuan squatting at the door of the kitchen, and couldn't help but be stunned, "Brother Feng, why did you two get up so early?" ”

"It's not that I got up early, it's that I haven't slept at all!"

Xie Xuan replied without raising his head, his eyes were fixed on the ground, as if there was some rare treasure there.

"What are you tossing if you don't sleep?"

Li Tianyuan stretched out his head to take a look, and said with little interest: "Isn't it just a stone?" I said you kid is still a baby. ”

Li Tianyuan couldn't find a single bone from his hair to his heels, although the stone was very beautiful, he didn't pay attention to it at all, took a few steps back to the courtyard, and began to stand on the pile to practice.

"Well-developed limbs and simple mind!"

Seeing Li Tianyuan's actions, Xie Xuan muttered in a low voice, but immediately focused on the piece of jade that had just been taken out of the strong acid.

"It's beautiful!"

Looking at the almost transparent piece of jade, Xie Xuan couldn't help but groan, if he didn't know that this thing had been corroded by strong acid, he couldn't wait to hold it in his arms and play with it.

"The method taught by Master really works!"

Qin Feng also showed an excited look on his face, he used to listen to theory, but after applying it to practice, Qin Feng could truly feel the strong visual impact brought by this change.

In fact, before starting, Qin Feng also had some doubts in his heart, a black stone, in just one night, became crystal clear, this is simply the ability to turn stones into gold.

"Brother Feng, let's sell this?"

Xie Xuan looked at Qin Feng, his eyes were full of admiration, if he hadn't been staring at it since last night, he couldn't believe that the stone could change so much.

"How easy are you to fake? There are still several processes to be completed. Qin Feng took a deep breath and said, "Little fatty, go and burn the fire, and then heat this stone!" ”

"Hey, Brother Feng, is it steam reaching 212 degrees? I'm sure I'll be in control of the heat! ”

Although he didn't sleep all night, the little fat man was full of energy, and he squatted on the stove to light the fire, and filled the pot with water and boiled it.

Qin Feng put the stone that had been treated with the impurities between the grains and the grains into the water, and then poured the pot of strong acid with a pungent smell into the sewer, and after carefully rinsing it with clean water several times, he took out the chromium salt solution he bought yesterday.

Chromium salt is one of the main products of inorganic chemicals, which is sodium dichromate and chromic anhydride, as well as a small amount of potassium dichromate, chromium oxide green, basic chromium sulfate and some chromium-containing pigments.

Chromium salts are widely used, mainly used in electroplating, tanning, printing and dyeing, pigments, medicine, catalysts, oxidants, glass ceramics, magnetic materials, wood anti-corrosion, metal polishing, etc.

In addition to these effects, chromium salts can also be used as a pigment to artificially inject into jadeite.

After boiling the jadeite in water with a steam temperature of up to 212 degrees Celsius for half an hour, it is immediately added to the chromium salt solution, which penetrates into the jadeite lattice, giving it a beautiful and attractive green color.

However, unlike civilian chromium salts, this method will make the objects added to the chromium salt solution contain a harmful radioactive substance, which will have a great impact on human health if exposed to it for a long time.

Therefore, when teaching Qin Feng this technique, Zai Yu once specifically told him to try to avoid fraud, this kind of method is indeed against the harmony of heaven.

However, Qin Feng did not completely follow the process taught by Zaiyu, after removing impurities and coloring, the preservation period of this jadeite will be very short, and it will not cause fatal harm to the wearer.

"Brother Feng, it's okay!" Half an hour later, Xie Xuan's shout sounded in Qin Feng's ears.

"It's up to you to make or break it." Qin Feng picked up the scoop and carefully put the rough stone into the chromium salt solution, and on the pure stone, a trace of the pale green luster of the chromium salt suddenly appeared.

If you want to implement your own jihua, this piece of jade is an indispensable link, with Qin Feng's current age, it is a little unrealistic to want an empty glove white wolf, and the jade soaked in the basin is an important prop for him to win the trust of others.

"Brother Feng, how is this like dyeing cloth?" Xie Xuan, whose face was stained with black ash, came over, looked at the stones in the basin with a nervous expression, and asked, "Brother Feng, how long will this thing take to soak?" ”

"It's almost two hours, Chubby, you go to sleep." When the rough stone is processed, what is needed is craftsmanship, which is not something that can be learned in a while.

"Don't, Brother Feng, I want to watch!" Xie Xuan rubbed his bloodshot eyes and shook his head, he had been involved in this matter from beginning to end, and the sense of expectation in his heart was not much worse than Qin Feng.

"Yuanzi, come here!"

Seeing that Li Tianyuan was standing on a stake and setting up a shelf, Qin Feng suddenly became angry, the two brothers were busy with a happy life in the future, this kid is good, and the whole thing is a big shopkeeper.

"Brother Feng, what's wrong? Am I doing it wrong? Hearing Qin Feng's shout, Li Tianyuan's face was nervous.

"You can't decorate anything else in your head except for practice?"

Qin Feng said angrily: "Don't practice this time, go buy some breakfast, don't just buy baked cakes, buy more meat buns, Xiaopang and I are hungry."

"Hey, I'll go!"

As the saying goes, half the size eats the poor old man, Li Tianyuan has already digested what he ate and drank yesterday, this will be hungry, after hearing Qin Feng's words, he hurriedly went to buy breakfast.

After breakfast, Qin Feng sent Li Tianyuan, who was "not motivated", to continue to stand on the pile, while he and Xie Xuan squatted next to the porcelain basin with the jade rough stones.

After waiting for the two hours to pass, Qin Feng poured out the chromium salt liquid in the basin, and suddenly, a piece of jadeite with a whole body of turquoise and crystal clear appeared in front of the two of them.

"Really...... It's beautiful! ”

Looking at the jadeite that showed a deep green color in the sun, Xie Xuan's eyes were full of fascination, he couldn't connect this jadeite with the broken stone from yesterday.

"Pretty is pretty, but it's fake!"

Qin Feng brought the basin under the faucet and rinsed it many times, and when the water washed on the stone, it seemed to be infected by that green, and the entire pool changed color.

"It's so beautiful, and I admit it!" Xie Xuan looked at Qin Feng and begged, "Brother Feng, leave a small piece and polish my ring face, right?" This thing is really beautiful! ”

Xie Xuan once saw a friend of his father's who wore a green jade ring, but the luster and greenness of the ring were far worse than the one in front of him.

"Didn't I tell you just now, this thing is harmful, it doesn't matter if you want to kill me!"

Qin Feng took the piece of jade in his hand, looked at it carefully in the sunlight for a while, and then turned his head and said: "Our process is too simple, and the chromium salt liquid is also used in industry, maybe it contains radioactive radioactivity, you dare to wear such a thing?" ”

Qin Feng was not scaring Xie Xuan, when Zai Yu taught him this method, he once told him a story.

It happened more than 60 years ago in the thirties, there was a boss specializing in jade, who spent a lot of effort, consulted many chemical experts in China at that time, and did a lot of experiments, and figured out this recipe.

At that time, the best jadeite that appeared in China was basically from the hands of this person, almost forming a monopoly, and no one could compete with him in the buying and selling of jadeite.

But just when the boss's business was booming, the news of his death suddenly came out, and someone found an imperial green ring in his hand.

This thing attracted the attention of the third lady of the Song family at that time, but what people didn't expect was that this ring face was actually a fake, and after identification, the ring face would radiate radiation harmful to the human body.

In order to dispel the panic of those who bought jadeite, the news only circulated in a small circle, but the recipe for counterfeiting was spread from this.

Zaiyu is the recipe that will be obtained, but then the Japanese invasion of China and the chaos of the war, as a plaything, jadeite has gradually been forgotten.

"What's the matter, do you still want it?" After telling Xie Xuan that story, Qin Feng looked at him with a smile.

"Brother Feng, I haven't lived enough." Xie Xuan subconsciously took a few steps back, and said with some regret: "It's a pity that such a beautiful thing can't be used." ”

"The real imperial green jadeite, more beautiful than this, now the country does not attach much importance to jadeite, we can pay more attention to this in the future."

Although he has obtained the inheritance of the Outer Eight Gates, Qin Feng does not want to get involved in the troubled waters of the rivers and lakes, and he already has some vague plans in his heart for the future.

Of course, the most important thing in front of you is to turn this piece of jadeite rough into jewelry, and then sell it, after several processing, the mold is considered to be out, but there are two most important steps behind.

"The bracelet is too labor-intensive, and the legendary pair of bracelets is also a little flawed, so let's just make a pair of earrings and a Buddha statue, anyway, the one is called Lafayette!"

Holding the piece of jade in his hand, Qin Feng's hands were covered with a layer of green luster, and after pondering for a while, Qin Feng finally made a decision in his heart.

The expenses have been not small in the past few days, and Qin Feng also knew that there was not much food left, so he returned to the house and took out the set of carving knives he bought yesterday.

"Keep your hands steady, your eyes quick, and don't hesitate when you go under the knife!"

Thinking of some of the tricks taught by the master, Qin Feng's weak and boneless hands scratched on the surface of the jade.

At the beginning, Qin Feng's hands were still a little rusty, but after ten minutes, Qin Feng's movements had become skillful, and where the knife fell, the jade debris and residue kept falling down.
