After rummaging through the pile of second-hand paints for a while, Zhao Chenxing's disappointment was palpable.
"No," he shook his head, then stood up and said, "There's no paint I need."
"Ah" The female college student setting up the stall and Liu Chengcheng were both surprised.
Then, the female student from the professional art school was unconvinced and asked: "Are you kidding?
We have the most complete range of paints here, including water-based, oil-based, watercolor, and oil paintings.
How can we not have what you want?"
Listening to the girl's question, Zhao Chenxing replied with a half-smile: "I am a craftsman, and the color I want is mineral pigment."
"Mineral Pigments" After listening to Zhao Chenxing's words, the girl setting up the stall suddenly shut up.
After the girl shut up, Liu Chengcheng asked Zhao Chenxing in confusion: "What are mineral pigments?
Is it so difficult to do?"
When asked, Zhao Chenxing told Liu Chengcheng in a low voice: "As the name suggests, mineral pigments are pigments made from natural minerals."
Zhao Chenxing told Liu Chengcheng that the biggest difference between this kind of pigment and the chemically synthesized pigments in the world is that it is "purely natural".
Mineral pigments must be naturally occurring and stable minerals in order to be prepared.
The preparation process is nothing more than grinding large pieces of ore into powder, and there is no process of raising the temperature or changing the chemical properties.
Such pigments have many irreplaceable advantages over ordinary chemically synthesized pigments.
First of all, mineral pigments are natural and have been around for hundreds of years.
Over the years, their chemical properties have become extremely stable, so the colors produced are bright and not easy to deteriorate, which can be said to have an eternal coloring effect.
In addition to this, due to their stable chemical properties, mineral raw materials will not damage wood compared to synthetic pigments.
It has also been an ancient choice of Chinese craftsmen for painting on carved beams and painted buildings since ancient times.
Therefore, craftsmen in ancient arts rely on these things to depict sacred sculptures and make painted buildings.
Of course, because there are many kinds of minerals of the same color, mineral pigments are also divided into grades according to the types of minerals they are prepared from.
Speaking of this, Zhao Chenxing also cited the longest-used red pigment as an example.
Generally, the red raw materials for chemical synthesis are hydrocolloids containing ferric iron.
Although this iron-red color is bright at first, it will gradually oxidize over time, and soon it will dull and turn into a dark color like rust.
For mineral pigments, red iron ore is selected for grinding and processing to make powder pigments.
Although this kind of pigment is also made of iron, because iron ore has existed for hundreds of millions of years and its properties are stable, it will not fade as easily as synthetic pigments.
However, red iron ore still has the problem of dull coloration that is difficult to solve.
Therefore, red iron is the lowest mineral pigment.
And what is better than red iron is cinnabar.
Completely different from red iron, the color-causing element of cinnabar is mercury, and mercury is a naturally bright red element.
There is almost no problem of color loss due to oxidation.
Therefore, the ore raw material ground from cinnabar ore is one level higher than red iron, and its properties are more stable and more beautiful.
However, cinnabar is toxic and is not good for human health if used too much.
Moreover, mercury will evaporate under certain conditions, which may easily cause the color to fade.
Therefore, cinnabar can only be regarded as a mid-to-high-end mineral pigment.
As for the best red mineral raw material, it has to be red agate.
Speaking of red agate, Zhao Chenxing said with envy on his face: "The color element of the best red agate is also iron, but this iron is wrapped in atomic crystals, which is extremely stable and will neither evaporate nor oxidize."
"When I was repairing cultural relics in the Forbidden City, I once saw a sandalwood six-sided sketch depicting a phoenix screen in the Zhongcui Palace.
The phoenix eyes on the screen were painted with fine powder of the best southern red agate."
When Zhao Chenxing said this, Liu Chengcheng's curiosity was aroused.
She asked expectantly: "So, the color must be great?"
"Of course," Zhao Chenxing nodded and said, "Those pigments are made of crystals and have good refraction, which is also very special.
Zhao Chenxing recalled: "Although it is only a thin layer, it has a three-dimensional effect that highlights the picture, and as the light changes, the eyes will open and close, as if they are alive."
After talking about the rare treasure he had seen, Zhao Chenxing felt a little disappointed in his heart.
He didn't expect to find peerless pigments like agate powder here.

However, if you give Duoduo money to make sculptures, it’s definitely not easy to fool around with synthetic paints.
First of all, they paid sixty-nine for the work, and they gave me a lot of face.
Secondly, now is the time for Zhao Chenxing to build a brand and create a reputation, so being casually fooled would be like shooting himself in the foot.
Neither Liu Chengcheng nor the female college student opposite him knew about Zhao Chenxing's inner loneliness and melancholy.
However, everyone can hear his profound insights into pigments, especially mineral pigments.
Facing Zhao Chenxing's preaching, Liu Chengcheng sighed at how well-informed Zhao Chenxing was, but the female college student running a street vendor felt that Zhao Chenxing was very pretentious.
"Oh, I can't tell.
Handsome guy, your conditions are quite high."
The college student raised his eyebrows and said: "The kind of thing you want is too expensive.
In a big stationery store, a 30-pack of nine-color sets can be sold for 5,000.
It's almost like drugs.
We students can't afford it, and we can't even talk about it.
There’s no need to buy it.” "" Zhao Chenxing muttered, and then asked: "Then do you know who in this market might have?"
When asked, the shrewd female student hesitated to speak.
She replied to Zhao Chenxing with sly eyes: "Handsome guy, news can be considered a commodity."
Hearing what the female student said, Zhao Chenxing was slightly startled.
These days, everyone is participating in the commodity economy, and even the schoolgirls talk about money without showing any concern for helping others.
However, Zhao Chenxing was quite happy to hear the girl's tone of asking for money.
Although talking about money coldly makes people scared, Zhao Chenxing also understands that what you pay for is worth the price.
The information obtained by paying money must be more reliable than free consultation in terms of authenticity.
There is no free lunch in the world, this is also the basic principle of life.
Zhao Chenxing smiled and said nothing after listening to the girl's aggressive tone.
Then, he took out fifty yuan and gave it to the girl.
The girl took the money, blew a kiss to Zhao Chenxing excitedly, then turned around, pointed to a fork in the northeast corner of the ghost market and said: "Where are you two going?
There is a little girl running a stall selling the mineral pigments you want.
She has been selling them for several days.
It seems that she came out because she was in trouble at home.
It's quite pitiful."
"Oh" Zhao Chenxing nodded, and then pulled Liu Chengcheng in that direction.
Behind them, the girl who had just made ninety-five yuan from Zhao Chenxing hurriedly closed the stall and called someone at the same time and said: "Hey Dr.
Wang, I'm Li Daniu and I have good news for you.
I finally made enough money so I can have sex reassignment surgery, hahaha":
