Chapter 311 The monk can touch it, and the Taoist can touch it too
When buying crystal glass tableware, you can distinguish between glass, leaded crystal glass and lead-free crystal glass by sound, feel, appearance, etc.
How to identify it is actually very simple, just listen to the sound.
When you tap the vessel gently or flick it with your fingers, the crystal glassware can make a crisp metallic sound, and a beautiful reverberation in the air, while ordinary glassware only has a dull "click, click" sound.
It was because he learned how to identify crystal glass products that Chen Wenzhe understood the art of identification.
After you learn the identification technique, after you draw a conclusion, the system can determine whether it is right or wrong.
For example, now, Chen Wenzhe confirms that the champagne glass in his hand is a lead-free crystal glass, and the system immediately confirms: the identification is correct!
However, this time he appraised the crystal champagne glass, but there was no feedback at all.
Chen Wenzhe knew that this time was not a real appraisal.
If you want to truly learn the art of appraisal, you still need to formally appraise an item, but there is no rush for this.
Chen Wenzhe was very excited to obtain the appraisal skill by accident, but what he valued most was the manufacturing process.
Making a crystal glass is not too troublesome. The main thing is to add various metals, such as lead.
Since the color, texture, and gloss of ordinary glass are not ideal, adding lead to the glass can increase the refractive index of the glass and make it look like it is made of crystal, so it is called crystal glass.
Some various shapes of ornaments, crystal glasses, crystal lamps, etc. are made of leaded glass.
Modern people all know not to use things containing lead casually, because lead is a heavy metal and will cause lead poisoning after entering the human body.
Therefore, there are certain standards for making leaded crystal cups.
According to EU standards, crystal glasses are divided into three types: lead-free, medium-lead and high-lead.
The lead oxide content of medium-lead glasses reaches 24%; the lead oxide content of high-lead glasses reaches 36%.
If the crystal glass container is produced in accordance with EU standards, no matter what kind of product or how much lead is contained in it, there are strict international regulations and it will be safe for the human body.
However, due to the lack of standards in our country, it cannot be ruled out that individual manufacturers are very arbitrary in their production and it is difficult to guarantee product quality.
As a result, it is difficult to sell domestic crystal cups at a high price.
Especially for some high-consumption groups, as long as they are right, they only buy expensive ones.
This is also the reason why no one wants many things from abroad, even though there are domestic products, even with better quality, because they don’t trust them.
In fact, no one else is to blame for this, it was entirely done by the Chinese themselves.
Not only manufacturers do it, but consumers also do it.
It can be regarded as the result of joint efforts, which has caused Chinese people to go abroad and buy Chinese products abroad.
Many people laugh at these people, thinking that they spend a lot of money and take off their pants to fart.
In fact, many people don't know that many domestic factories have double standards for their products. The quality standards for exports are different from those for domestic sales.
It makes sense for people to go abroad to buy domestic products that are exported to foreign countries!
He shook his head and took back his divergent thinking. This time he also obtained a lot of secret recipes, which can be turned into wealth in the future.
Chen Wenzhe worked hard to digest the information obtained this time, mainly about the various manufacturing processes of crystal cups.
Crystal cup is a type of glass. The main component is silica, but lead, barium, zinc, titanium and other substances are introduced into it.
If lead is introduced, it is lead crystal.
If barium, zinc, titanium and other substances are introduced, it is lead-free crystal.
The content percentages of various substances here completely fell into Chen Wenzhe's eyes. What he wanted was actually the formula accumulated from these experiences.
As for the production process of the crystal cup, it is really not difficult for Chen Wenzhe. It can't be more difficult than the drawing process in porcelain making, right?
Of course, making glass handicrafts is a little different from making porcelain, but the difference is not big.
The body of the crystal cup is made of high-grade crystal glass and is carefully processed and fired with superb skills.
Generally, a high-temperature firing process of 640°C is used to reach the critical point of crystal glass melting. Such works are transparent, pure and non-toxic.
During this process, an annealing process is also used to ensure that the cup body can withstand instantaneous changes in hot and cold, is explosion-proof and crack-proof, has no tail vacuum, and has the characteristics of high transparency, strong crystal feel, and wear resistance.
The crystal glass products fired in this way are crystal clear, elegant and generous.
And this is just the outside, the inside is even more beautiful!
The high-end crystal glass has a double-layer glass structure, which has a certain effect of keeping cold and heat;
The mouth of the cup is also polished and smoothed by a special process, making it comfortable to drink;
It is more convenient to use, more reasonable in design, and more user-friendly.
Compared with ancient teacups, this product has been promoted by many businesses and is very popular among modern young people.
These little advantages, combined, really have an impact on traditional porcelain.
No, it has already had a huge impact on the domestic porcelain manufacturing industry.
Since modern times, domestic porcelain exports have actually lost any advantage at all.
The modern porcelain manufacturing industry not only needs to be internalized, but also has to compete with many large foreign manufacturers, such as Neon, Germany, France and other countries, which are now major porcelain manufacturing countries.
"Learn from the strengths of the barbarians to defeat the barbarians! You have to see the strengths of others and don't rest on your laurels!"
Chen Wenzhe played with the crystal cup in his hand. He did not expect that just a whim would lead him to see a huge market.
This is typical. The monk can touch it, but why can't the Taoist priest touch it?
"Ding dong!"
While Chen Wenzhe was still digesting the craftsmanship of making crystal cups, the door of the guest room rang.
Putting down the crystal cup, Chen Wenzhe planned to go to the cruise ship restaurant when he has free time and touch all the high-end crystal products inside.
Well, thinking of touching, Chen Wenzhe thought of the second inheritance task.
Isn’t the mission this time just to touch the Jingyun Bell?
It seems that the most essential point of all inheritances is touch!
“I always feel that the system is a little unfair, but it’s definitely not that I’m unfair!”
Muttering in his mouth, Chen Wenzhe opened the door.
Zheng Yu did not enter the door, but stood outside and said, "Aren't you hungry?"
"Huh? From what you said, it seems like you know I haven't eaten?"
Zheng Yu simply rolled his eyes: "You slept all day long, I'm not as good as you."
"It's been a whole day? It's really inconvenient without a mobile phone!"
Chen Wenzhe felt a little emotional. Time passed so fast. He didn't even have time to feel hungry. It had only been one day?
"Can you be more careful? Now that you are so rich, you still don't know how to buy a watch? At least you should have a waterproof watch!" Zheng Yu said a little speechlessly.
Chen Wenzhe was stunned. It turned out that he could tell the time without relying on his mobile phone.
His family is poor and he really doesn’t know anything about green water ghosts!
