Chapter 1,110: Difficult to imitate does not mean impossible to imitate
Looking at noodles does not mean whether there is too much white flour on the steamed buns. This is a professional term that most people really don’t know.
Chen Wenzhe knew as soon as he heard it that he was talking about losing fans.
Depowdering refers to the fact that powdery matter falls off the ceramic surface after being cleaned and touched due to years of weathering.
It is difficult to imitate. The weathering of powder is slightly milder than that of off-powder. Hair powder usually only appears on high-end ancient porcelain. The colorful pastels of the Qing Dynasty are just dull.
Powdering refers to the phenomenon of weathering of porcelain over time. The original body is more obvious, and there is powdery substance on the surface, which is not found when wiped by hand.
If the weathering is more serious, it will be winter melon frost phenomenon.
If the winter melon frost phenomenon is more serious, the powder will come off and fall off. If you wipe it with your hands, there will be powdery matter.
Along with the powdery phenomenon, there are tofu flowers and white moiré, which can be seen under a magnifying glass.
You should know that pastels are based on glass white. The glass white can be clearly seen on bowls, basins, plates, especially large porcelain.
The powdery texture of pastels is very important.
It has a certain thickness, but this pastel is not very strong.
Authentic products will naturally shed during their circulation over a long period of time. This natural shedding is a very important feature in identifying the authenticity of pastels.
"Hey, this is what I did!" There is some powder peeling off, but it's very slight, which is serious.
If the depowdering is severe, it will definitely seriously affect the price of porcelain.
It's fine now. There are signs of powder loss, but it's very slight and doesn't affect the beauty of the porcelain at all. This kind of grasp of details is really amazing.
"And the way Boss Chen handles this explosive glaze must be master-level!"
Holding a plate, Wu San moved his body while looking at it.
After he came in, he quickly saw the exhibits on the museum shelves.
Many of them were not domestic porcelain at first glance. Considering the area where they were now, Wu San knew that they must be porcelain from South Vietnam.
These porcelains are definitely worthless when they enter the country.
However, other porcelain with obvious domestic characteristics is different.
The most important thing was that Wu San was very puzzled by some of the porcelain. No matter how he looked at it, he felt that the signs of aging were too obvious.
Just when he wanted to go over and take a look, he didn't expect that someone was faster than him and actually picked up a piece of Kangxi's porcelain.
Although it is just a Kangxi pastel porcelain plate, it is a porcelain with a history of more than 200 years, and the distressing technique on it is different from that of Qianlong.
After all, the porcelain of the Qianlong period is missing fifty or sixty years of history.
"Exploding glaze?" Wu San stopped and asked.
"Yes, it's just blasted glaze. In fact, it also has flint red and ox hair patterns. It's all so classic!"
Whether the glaze on the rim is natural or not is also an important feature in identifying the authenticity of porcelain.
The Kangxi pastel plate in front of Wu San originally had gold inlay on the rim. As time went by, the gold had gradually fallen off.
The loss of gold color is also a characteristic for identifying the authenticity of pastel porcelain.
Wu San didn't know much about appraisal, but the two old men knew very well that the details of this batch of porcelain were perfectly made.
For example, the texture of the glaze on the rim of porcelain is also very good, like milk, with a certain degree of turbidity. It is not very clear, but you can also see the inner halo of precious light. This kind of light is emitted from the inside.
This is a very typical characteristic of the times.
Seeing that layer of natural precious light, the two old men were a little silent.
Although they could tell something was wrong, they couldn't say it out loud.
Because this layer of precious light is so natural, even if there is no other light, does it mean that it is an old fake?
Although they couldn't use their knowledge to defeat Chen Wenzhe, they couldn't say anything.
"Boss Chen, is this Baoguang too much?" Suddenly, an old man asked.
Chen Wenzhe was stunned. Is this Baoguang too exaggerated?
The old man was shocked when he saw Chen Wenzhe's reaction. It was obvious that Chen Wenzhe didn't understand.
What is Baoguang? If ancient porcelain that is more than five hundred years old has not been exposed to the sun, water, or fire, or on a muggy day or a foggy day, white light can be seen around the ancient porcelain, which is large and round, and is different from hazy light.
When the light is strong, the partition cloth and paper can be seen.
Because of its magic, the predecessors called it Baoguang.
Looking at the proud old man, Chen Wenzhe smiled: "This is pastel!"
"Of course, the pastel color has clam gleams on it. This is normal, but it's too warm and natural. It looks like a precious gleam no matter how you look at it!" Another old man also said.
Chen Wenzhe was a little silent. He really didn't expect this. He also knew that only porcelain that is more than four or five hundred years old can produce Baoguang.
Of course, not all porcelain is available, and those that are poorly preserved will definitely not be available.
However, the porcelain he made must have been well preserved, but the time was too short and it would last for three hundred years.
However, if you really want to make porcelain that is more than four or five hundred years old, there are more problems.
"Thankfully it's not purple in color!"
"Yes, if it turns purple, it can be determined to be purple light!"
Chen Wenzhe was speechless. Only then did he realize that the two old men were really capable.
This kind of detail that he didn't notice, they also noticed.
However, purple light could not appear on Qing Dynasty porcelain, and he was not wrong about this.
What is purple light? Looking sideways at the blue and white porcelain of the Tang, Song and Yuan Dynasties, you can see a faint purple light.
Because there is no precious color or aura of metal, it is called "purple light".
Blue and white materials that can produce purple light have been valuable since ancient times, and are worth twice as much as gold.
If you want to make a high imitation of this level, I still don’t know if you can find similar ancient mineral deposits.
As for Purple Baoguang, it refers to the fact that after the blue and white porcelain of the Tang and Song Dynasties was unearthed, it did not dry slowly in the shade. When exposed to the sun, a metallic shining purple light appeared.
It's not a partial one, it's all porcelain. It will gradually disappear after being displayed for about ten minutes to half an hour in a place exposed to sunlight.
Later generations didn't know the reason, so they called it "Purple Treasure Light".
If you now soak the blue and white porcelain of the Tang and Song Dynasties in water for three to five years, and then take it out to the sun, you will still see the purple light, but it will be very dim and not strong.
This phenomenon definitely cannot be imitated, and no one wants to imitate it, mainly because it is unnecessary.
Just a few words made Chen Wenzhe very passive.
However, Chen Wenzhe struggled to listen, but Wu San next to him simply couldn't understand.
"Aren't these porcelains all old?" Wu San didn't want to discuss too professional matters with the two old men, so he immediately changed the topic.
"Of course, for example, this cow hair pattern should be made using new technology, right? Boss Chen is indeed a young man and keeps pace with the times!"
Cow hair pattern is a kind of flowing pattern like coarse ox hair, which is dynamic, but not as gorgeous as live flowing pattern.
The ox hair pattern in each period is also different and difficult to imitate. Of course, being difficult to imitate does not mean that it is impossible to imitate. For experts, it is much more difficult to imitate than the ox hair pattern.
Chen Wenzhe took a look and realized that this was really not done by him, but by Zhang Gu.
Among the employees from the academy who came to South Vietnam this time, Zhang Gu was the most talented and ambitious.
