People like Wu San, who have always been able to get along like a fish in water, should not be underestimated regardless of whether they have some cultural background. At least they speak very well.
Wu San started the conversation, and the rest was for the two old men to perform.
"Do you know how flint red is formed?" Mr. Zhou said nonchalantly.
Anyone who plays antiques should know that flint red. If you don't know, it is pure leek.
Several people here understand it, even Wu San understands it, but he doesn't understand much.
As for Chen Wenzhe, he has not really studied flint red specifically, but he knows how to make a qualified flint red, and that is enough.
Of course, people in Jingzhen are very professional. As long as it is related to porcelain, they have studied it in depth.
For example, this seemingly ordinary flint red, flint red refers to the exposed parts of ancient porcelain, which shows red, but also yellow-red, purple-red, gray-red, etc.
In some cases where the flint redness is severe, one or two millimeters may creep up from the tire to the glaze surface.
Many people would think that this phenomenon must only be seen on antiques.
In other words, the emergence of this phenomenon is a phenomenon of aging.
But this is not entirely true, because some porcelain has it when it comes out of the kiln, commonly known as "kiln-turned flint red".
The color that gradually forms after leaving the kiln is called "acquired flint red".
The kilns in ancient times were made of flint red, and their appearance at that time can only be inferred from modern porcelain.
After several years, it changed beyond recognition because a series of other ancient porcelains interfered with it.
Therefore, when looking for the characteristics of ancient porcelain, flint red is the main color found in later times.
It usually appears in the recesses of the utensils, on the support nails, on the seams, on the tendon lines, on the fire-related dirt, and there will be a metallic luster on the surface. This is caused by thousands of years of oxidation and fire-related exudation.
If it lasts no more than a few decades, it will not produce metallic light.
The older it is, the stronger the metallic light is.
Of course, not all porcelain will form flint red, because the main component of flint red is iron oxide.
If the iron content of the porcelain itself is extremely low, it is not easy to find flint red, and some require the help of a 100-fold magnifying glass.
If there is no trace of flint red, it can be judged as new porcelain.
If the flint red metallic light in the recessed part of the porcelain is not obvious, it needs to be combined with other ancient porcelain characteristics to make a comprehensive judgment.
Having long known that the two old men were masters, Chen Wenzhe was not surprised at all that they knew Huo Shihong.
The large plate he made was kiln-made flint red, but later he made it look old, such as metallic luster and so on.
In fact, the most distressed color is definitely not flint red, because it is too obvious and too many people do it.
For example, the distinctive ox hair pattern and flint red color will definitely not stump the experts from Jingzhen.
Therefore, Chen Wenzhe just listened to their flattery and said nothing. If he wanted to be serious, the two old men might laugh at him.
However, these two old men were not without eyesight. Although they did not take a closer look, they also saw some of the bubble pits on the surface of the porcelain.
This is what is really powerful, and these are some of the unexpected gains Chen Wenzhe gained through that piece of secret-color porcelain.
After being depressed for a while, Mr. Zhou looked at Chen Wenzhe again: "Xiao Chen, is that porcelain made of broken bubbles?"
As soon as he heard this, Chen Wenzhe laughed. This old man could really bear it, and he only mentioned it now.
"It was handled so well. After the bubbles were broken and soaked in water, it turned into what it is now. It's not easy!"
Lao Li was also a little emotional. After all, the porcelain in front of him was very beautiful, so the treatment of bubbles was very demanding.
"It's true!" Chen Wenzhe was still very interested in Jingzhen's old-fashioned techniques.
The main reason is that he has seen too few modern high-imitation porcelains, because as long as they are high-quality imitations from Jingzhen, they are usually sold to top auction houses, and eventually end up in the treasure houses of some big private collectors. Where can he see them?
arrive?
Only by seeing a lot can one become knowledgeable. He has never seen a few pieces of high-quality antique porcelain, so naturally he doesn't understand the technology in Jingzhen.
Just like the living flow pattern mentioned earlier, he has never even seen it, so how could he imitate it?
The two men in front of them have already shown off their skills a lot, and it's time for Chen Wenzhe to show off, otherwise he will really make these two old men look down upon him.
I met two masters, and it seemed that they also wanted to communicate. Chen Wenzhe naturally would not refuse.
After all, he really has a deep understanding of the bubbles in the porcelain glaze, as well as the bursting of bubbles, and even all subsequent changes.
Bubble breakage refers to the bubbles on the glaze surface that break due to weathering, silicone formation, cleaning, and friction over time.
Generally, what you see is the broken bubbles on the upper layer of the glaze. When the damage to the glaze surface is too serious, you only see broken bubbles on the middle and lower layers.
This phenomenon occurs on Song porcelain and is difficult to imitate.
If you find smelly dry black or yellow water spots in the broken bubbles, it can be determined to be ancient porcelain.
There is another feature called ice bursting, which is very magical and beautiful. The top of the bubbles appears as radioactive ice cracks, which is even more difficult to imitate. Very few people can imitate it.
This is also an important reason why Ru kiln and ice-cracked porcelain are difficult to imitate.
As for the smelly dry black and yellow water spots, they are also special symptoms on ancient porcelain!
Smelly dry black means that putrefactive organic matter stains ancient porcelain, most of which are found in plain bodies and broken bubbles.
After long-term blistering, it will soften, swell, and be washed off.
Counterfeiters use river and pond sludge to make them.
There are differences under a magnifying glass: smelly, dry, black, amorphous, river mud, with soil particles.
In particular, the smelly dry black penetrated into the micro-broken bubbles takes hundreds of years to form, and usually appears on ancient porcelain before the Ming Dynasty.
There are also some on porcelain from the third and third dynasties of the Qing Dynasty, but they are rare and difficult to find with a magnifying glass.
From the late Qing Dynasty, a little bit can only be found on low-temperature porcelain that is not fired well.
As for yellow spots, or golden spots, this refers to the traces of gold left by gold objects that have squeezed ancient porcelain for many years and penetrated into glaze bubbles or rough areas.
This kind of stain cannot be copied. The older it gets, the deeper it penetrates and is not easy to clean off.
Of course, yellow water spots are easy to make. As the name suggests, the yellow marks left behind when water is immersed in the burst bubbles are yellow water spots. This is easy to imitate.
But there is another kind of soaked yellow paste that is more difficult to imitate. This phenomenon usually appears on Song Guan and Ge porcelain.
After soaking in clear water for a day, the clear water will produce a yellow and turbid feeling, such as yellow glaze, yellow glaze, and Liao yellow glaze, which is more conspicuous.
This is suspected to be formed after the iron-chlorine compound in the gold wire and yellow glaze is hydrolyzed. Until now, Chen Wenzhe has never heard of it, let alone seen any imitation.
To communicate, there must be back and forth. Chen Wenzhe talked about some techniques for breaking bubbles.
A bubble hole is a large hole that appears in the glaze after a large bubble on the glaze surface bursts. The mouth is small and the inside is big.
The inner shape is different from the brown eye, the bubble eye is a spherical hole.
And as long as the bubbles are broken, dust and so on will definitely accumulate in these bubbles over time.
The difference appears here. Because of the different external environment, the substances contained in the bubble eyes are different, which forms various kinds of bubble eyes.
