Chapter 318: Gold Washing Water
Facing Zhao Jinmai's complaint, Liu Yifei smiled and reassured: "Brother Yi is joking with you, just don't take it seriously." β
Seeing this, Zhao Jinmai could only mumble stupidly: "I know that you are reluctant to talk about him..."
She said vaguely, and the audience didn't hear it clearly, but Liu Yifei understood what she was humming.
Shaking her head helplessly, Liu Yifei looked at Li Yi and asked with a smile: "Brother Yi, then do you have time to help us make some skin care products with Baiqi?" β
"Well, by the way."
Li Yi casually agreed.
Seeing that he agreed, Liu Yifei smiled at Zhao Jinmai and said, "Okay, Brother Yi will make some skin care products for you at that time." β
When Zhao Jinmai heard this, he was satisfied and quipped: "It's still effective for you to speak." β
While they were laughing, Li Yi had already glued the gold wire pattern to the bowl tire.
The next thing he had to do was to burn all the gold threads on the gold tire.
After placing the glued gold wire on a crucible, Li Yi turned around and lowered the temperature of the kiln to 800Β°C.
He then picks up the tyre with pliers and feeds it into the kiln.
Seeing that he didn't fix it in any way, he directly sent the bowl tire into the kiln, Geng Wanhua couldn't help but remind: "If you put it in and burn it directly, the pattern will fall off." β
This is the experience accumulated by the expert group after many experiments.
But Li Yi casually pointed to the mouth of the kiln: "Whether it falls off or not, you can see it yourself." β
Seeing him say this, Geng Wanhua and Cai Yi were a little curious.
Where did he get his confidence?
Is he really not afraid of falling off?
Geng Wanhua glanced at Cai Yi, and then walked to the mouth of the kiln.
He originally wanted to see the firing situation, but Li Yi said this, just as he agreed.
The special structure of the kiln prevents hot air from blowing out of the kiln mouth.
However, the high temperature of 800Β°C in the kiln still projects a lot of high-temperature rays from the kiln mouth.
Geng Wanhua came to the mouth of the kiln, squinted his eyes, and looked inside, but found that it was dazzling, and he couldn't see anything clearly.
Master Han on the side kindly brought him a piece of sunglasses and handed it to him.
Geng Wanhua thanked him, took the sunglasses, and put them in front of him.
With the shielding of the sunglasses, he could see clearly the golden bowl tire that was being scorched by the high temperature inside.
But when he saw the bowl clearly, he couldn't help but be stunned.
In the kiln, the bowl tire sits on the crucible at the end, and all the sticky gold wire patterns are glued to the wall of the bowl end-to-end, and none of them fall off.
Seeing this, Geng Wanhua was stunned.
How so?
Obviously there is no fixation at all, why haven't any of those gold wire patterns fallen off?
They're just glued to them with baiji, huh?
At a high temperature of 800 Β°C, no glue is used, how can Baiji glue still stick?
Suddenly, he noticed that a fire suddenly appeared on the outside of the bowl wall, and several sparks popped out at the same time.
Then, a fire suddenly erupted in another place, and sparks burst out.
Soon, the golden bowl tire was like a firecracker, and it kept blazing outward.
Seeing this scene, Geng Wanhua suddenly understood.
He looked back at the baiji gum in the glass bottle next to Li Yi's hand in surprise, and asked, "There's solder in there?" β
Seeing that he guessed it so quickly, Li Yi was also a little surprised.
But Li Yi didn't deny it, just nodded and smiled: "Bai Qi melts when it encounters fire, and it just plays a fixed role."
When you enter the furnace, you must still use solder to weld the gold wire. β
Geng Wanhua didn't understand: "But then the gold will not be pure!" β
"It's not a pure gold bowl, why do you want to be so pure?"
Li Yi disagreed: "And it's not that it can't be washed off, just go through the gold washing water." β
Hearing him say this, Geng Wanhua was stunned, and then nodded: "Makes sense." β
Gold washing water is sloppy water, that is, sulfuric acid solution, which has a strong corrosive peeling effect on metals.
The main components of solder are metal oxides and aluminum powder, which, when burned, can indeed contaminate gold.
However, the cloisonnΓ© bowl is indeed not made of pure gold, and there will be glaze between the gold wires and on the surface.
Therefore, as long as the pure gold luster of the surface can be guaranteed, it is not so important whether the internal adhesive weld is pure gold.
Li Yi was also observing the condition of the bowl tires in the kiln.
Seeing that the bowl tire was no longer on fire and bursting into sparks, he clamped it out with tongs.
At this moment, the golden bowl has become a "flower bowl", and the wall of the bowl is black and gray, as if it has been burned as the bottom of the pot.
Putting it aside to cool down, Li Yi took out a brown-yellow glass bottle and a glass beaker.
The brown-yellow glass bottle contained water, and when he opened the bottle, he poured it into the glass beaker.
Then, he picked up the golden bowl tire and put it in the cooling water just now, so that its temperature cooled down.
Then, he wiped the water dry and put the golden bowl tire into the water beaker.
The camera zoomed in on the close-up, and everyone in the rear also stretched their necks to watch Li Yi's movements.
I saw that after Li Yi put the golden bowl tire into the water, the originally burned golden bowl tire returned to its original pure gold luster at a speed visible to the naked eye.
Seeing this scene, there was an exclamation at the scene.
"Wow!"
In the live broadcast room, the audience also exclaimed.
"I'll make up! So amazing? It feels like magic! β
"What's in that brown glass bottle? How do you feel like you're doing a chemistry test? β
βH2SO4οΌ It's sulfuric acid, right? No wonder you can wash the gold clean! This thing is corrosive! β
"Why do I feel like Brother Yi is becoming more and more like a wizard? can cook, mix rouge, build equipment, and take out concentrated sulfuric acid at will, which has to be put in the game, how much is a villain boss! β
The audience was joking in the barrage area, while Li Yi took out the golden bowl tire from time to time to observe.
Seeing that all the discolored areas on the golden bowl tire had returned to pure gold, he took the golden bowl tire to the side of the bucket and brewed it and washed it.
After washing it again, he took the golden bowl tire to the faucet by the wall and rinsed it again before taking it back.
Later, he ordered blue, and he had to hold the bowl tire in his hand.
If you don't wash it clean, those sulfuric acid solutions are very bad for the skin if they get on your hands.
Back in front of the table, he placed the golden bowl tire on the table, let the camera closer, and took a close-up of the audience.
Seeing the golden bowl tire that was fully restored to gold, the audience was amazed.
But when Li Yi saw this, he reminded them: "This is concentrated sulfuric acid, also called water, and the so-called gold washing water in many gold shops is this thing."
Its effect is indeed very strong, but it directly corrodes a layer of gold objects, and it will lose grams.
Therefore, if you have gold jewelry, don't take it to a gold shop and let people wash it with this kind of gold washing water.
After washing the gold, these gold washing water can still refine gold, and some profiteers rely on this method to trap people, so you must pay attention. β
