Baojian

Chapter 53

The yard was ugly without a door. After chopping dry firewood, Xie Xuan removed a broken door panel in the house and blocked the entrance of the yard.

After going in and out for a long time, there was loud snoring in the room. Boss Li was not affected at all, and Xie Xuan was itching with hatred, but Qin Feng caught him, so he could only work obediently.

"Little Fatty, break up all the briquettes and throw them into the stove, the stove is too small!"

Most families in the north have stoves. Seeing that the briquettes stove obviously couldn’t meet the temperature he needed, Qin Feng brought the boiled iron pot to the stove, smashed the briquettes and threw them in together with Xie Xuan. .

With a few pieces of burnt briquettes as the fire starter, and the dry firewood brought by Xie Xuan, the stove that had not been used for a long time quickly started to burn, and the flames went straight out along the stove eye for adding firewood.

Seeing the blisters from "Cuckoo", Qin Feng picked up the stone from the stove, gently put it into the iron pot, and then tightly covered the pot.

"Brother Feng, you... what are you doing? This... this stone can't be eaten?"

Xie Xuan, who was squatting aside to add firewood to the stove, was dumbfounded. He didn't understand the purpose of this pot of boiling water until now, but at the same time, he became more and more confused.

If it wasn't for Qin Feng's well-organized performance when doing these things, Xie Xuan would definitely think that he had a neurological problem and put the stones in the pot to boil. Let alone Xie Xuan has never seen it, even if he has never heard of it.

"You kid knows how to eat?"

Qin Feng glared at the little fat man angrily. He would also be a little nervous. After all, the current operation process is dictated by the master, and Qin Feng himself has not tried it. Whether it will be successful or not, he has no idea.

"No, the fire isn't big enough, fat, you go pull the bellows!"

Qin Feng took out an industrial thermometer from his pocket. This thing was bought at the time of buying chromium salt solution, and it will be used in the next few links.

Opened the lid of the pot a little, Qin Feng inserted the thermometer in it for a test, took a look at it, Qin Feng handed the thermometer to Xie Xuan, and said: "It's still a few tens of degrees away, this thing is for you, wait until the pot When the steam in the oven reaches 212 degrees, do not reheat it."

Xie Xuan, who was holding the thermometer, was a little at a loss, and shouted at Qin Feng, who turned around and walked outside the house: "Hey, brother Feng, I...I don't know how to use this thing."

"Just put the metal end in there, no problem."

Qin Feng left the room without looking back, looked up at the sky, and murmured: "It's easy to say, but it's really hard to do!"

Ignoring Xie Xuan who was yelling in the kitchen, Qin Feng went straight out of the yard, April in the north is still a bit cold, it will be past nine o'clock, the street looks unusually deserted, Qin Feng's figure quickly disappeared Into the night.

After more than half an hour, Qin Feng returned to the yard, but he went out empty-handed, but now he was holding a glass jar in each hand, which seemed to contain some liquid, which was constantly dangling.

"Hey, I said Fatty, have you been to Africa for a while?"

Carrying the glass jar to the kitchen, Qin Feng was immediately delighted. Xie Xuan, who was originally fair-skinned, would now have a dark face. Except for a pair of teeth, there was nowhere to find any whiteness.

"Brother Feng, Master Feng, you are finally back!"

Seeing Qin Feng, Xie Xuan felt sad. When did he do this job?While burning firewood, he had to pull the bellows, and finally he couldn’t forget to test the temperature of the steam. He was so busy that he wished he could have two more hands.

"Xuanzi, don't complain, after learning this skill, you will never have to worry about food and drink in your life."

Qin Feng carefully put down the glass jar in his hand, went to the side of the stove, took the thermometer, put it in the water for a test, and his face suddenly showed joy.

"Little fat, you are really a person who eats this bowl!" Qin Feng patted Xie Xuan on the shoulder and said, "Keep this process in mind, and remember the temperature too."

"Brother Feng, I've remembered it a long time ago. Isn't it because the temperature of the steam reaches 212 degrees?" Although Xie Xuan didn't know why, he was not confused. He knew that Qin Feng must have his reasons for doing this.

"Okay, don't burn it now." Qin Feng saw that the fire was almost ready, and stopped Xie Xuan.

Seeing Qin Feng bring a porcelain basin from the house, and pour the liquid in the two jars into the porcelain basin, he couldn't help asking curiously: "Brother Feng, what are these two jars containing? Where did you get it?"

"Hey, don't get so close, you'll be hurt if it touches your skin."

Qin Feng stopped Xie Xuan, who was approaching, and said: "One of these two is concentrated hydrochloric acid, and the other is concentrated nitric acid. Remember, put 40.00% concentrated hydrochloric acid and 60.00% concentrated nitric acid. Together, we will call it Wang Shui!"

In fact, strong acid needs a special container to store it, but Qin Feng didn't have any good containers, so he could only dig out a porcelain pot from the house. I don't know if he used to grow flowers or what.

Xie Xuan scratched his head, and said with a bitter face: "What concentrated hydrochloric acid and concentrated nitric acid? Brother Feng, I don't understand!"

Qin Feng glanced at Xie Xuan helplessly, and said, "You kid, learn chemistry for me in the future. This stuff is strong acid, which is many times more corrosive than sulfuric acid. Do you understand?"

"Sulfuric acid? This... I know this!"

After hearing Qin Feng's words, Xie Xuan couldn't help taking two steps back, his eyes widened and he asked, "Brother Feng, where did you get this thing?"

In the mid-80s, a foreign film called "Singing at Midnight" was released in China. The protagonist in it was disfigured by being splashed with sulfuric acid on his face. The ugliness of the image scared many people.

Xie Xuan's chemistry grades were a mess, but he knew the power of sulfuric acid through that movie, and his face suddenly became a little weird. Could it be that Brother Feng concocted this thing in order to block the road and rob it?
Qin Feng replied casually: "There are plenty of them in the school's laboratory. This is industrial sulfuric acid, and it's not worth much."

On the way back, Qin Feng took a fancy to the Shishi University of Science and Technology not far from Li Tianyuan's home, but it was still daylight, so he didn't do anything.

Of course, Qin Feng said it easily, but it took a lot of effort to steal the strong acid from the two glass jars, and was almost discovered by the school patrol team.

It's just that chromium salt solution can be purchased from outside, but dangerous goods such as strong acid can't be bought casually, and you must issue a unit certificate to do it. Qin Feng has to take this risk.

While talking in his mouth, Qin Feng's hand didn't stop. When the two strong acids were mixed together, a pungent yellow smoke came out of the porcelain basin.

Putting down the glass jar, Qin Feng took out the rough jadeite from the pot with a ladle, and put it directly into the basin. The hot stone encountered strong acid, and with a sound of "sizzling", the smoke became bigger and irritating. Xie Xuan, who was standing aside, burst into tears.

"Okay, let's go out!"

Qin Feng also couldn't bear the smell in the kitchen, so he pulled Xie Xuan back out. It took more than half an hour for the smoke in the room to clear away, but the unpleasant smell filled the entire yard.

"Brother Feng, what's the point?"

Xie Xuan is not stupid, he has already seen some ways, Qin Feng seems to be using this method to change the stone, but there is some mystery in it that Xie Xuan can't see through.

"Little Fatty, soaking the rough jadeite with strong acid can dissolve the impurities between the grains of the jadeite. Without these impurities, the jade seeding water will become transparent, and the jadeite in the shitty ground can also become glass. kind……"

Qin Feng intends to train Xie Xuan, and he explained in detail, "In fact, it is best not to heat the jade during the soaking step, which is used when adding the color, but we don't have enough time, we can't wait that long, it's a long journey Take a shortcut."

"The shit turned into a glass seed? This...how is this possible?"

Xie Xuan opened his mouth wider the more he heard it, and said with an unbelievable expression: "Brother Feng, with this technology, wouldn't we make a fortune?!"

After following Qin Feng for two days, Xie Xuan still picked up the difference between different grades of jadeite. Although the current price of domestic jadeite jewelry is not as good as that of Hetian jade, the value of top-quality jadeite carved from glass species starts at [-]. of.

"What are you thinking, boy? This is old-fashioned, cough, it sounds better to say old-fashioned, this is actually a fake, the real can't be fake, and the fake can't be real, understand?"

Qin Feng patted the head of Xie Xuan, who was dreaming of getting rich, and said angrily: "The internal structure of jadeite soaked in strong acid will be greatly damaged, and the jadeite will become weak, and the bright and beautiful color It will also fade slowly. If the craftsmanship is more detailed, the fading time is about three to five years..."

Qin Feng glanced at the kitchen, thought about it for a while, and then said: "We are doing rough work, just look at the present and don't care about the future. I estimate that in the last two to thirty days, the damaged structure inside the jadeite will be fully revealed. , I’m afraid it will shatter if you don’t touch it…”

Speaking of this, Qin Feng's face became serious, "The most important point is that some emeralds made of chemical corrosive agents will contain radiation, which is harmful and useless if worn on the body. Xie Xuan, this prescription is against heaven. And, you can only deal with profiteers, and you can't use it easily..."

At the beginning of this century and in the 30s and [-]s, jade was popular for a period of time, and the benefits of counterfeiting were very rich. After some people continued to think about it, they left this prescription that was passed on to Qin Feng.

According to Zai Ye, even in the 30s and [-]s, not many people knew about this craft, and he got it from a disciple of Qianmen by accident.

Therefore, Qin Feng has reason to believe that the third wave of emerald fever in China has just emerged, and those who specialize in the manufacture and sale of fake products have definitely not worked out this method, which is also where his confidence lies in the subsequent layout.

"Brother Feng, I understand, but why do I feel that we are profiteers?"

Although Xie Xuan still didn't understand, he kept Qin Feng's words firmly in his heart. No one could have imagined that the largest jade profiteer in the country would start from such a dilapidated small courtyard.
