No one would like mercury, so even if it is an imitation of ancient porcelain, it is generally unnecessary, and no one would add some metallic mercury to offend people.
I have to say that Jingzhen is quite knowledgeable, and Chen Wenzhe gained a lot from just a few chats.
Originally, he thought that he was already very good at making things old and knew a lot about it.
There are so many techniques including removing smear, patina technique, water rust technique, soil rust technique, blood qin technique, chicken claw wrinkles, polishing technique, clam light technique, how many people can know it all and be omnipotent?
But he forgot that every industry advances with the times.
Of course, some ancient technologies have reached their peak, and modern people may not be able to do them.
However, the same effect can definitely be achieved, but the process is different.
This is similar to how college students and primary school students solve word problems. It will be more difficult for primary school students because their knowledge is too narrow.
But college students are different. They can use many advanced skills to solve elementary school-level application questions in various ways.
The same is true in the manufacturing industry, but when it comes to old-fashioned methods, modern people are even more powerful because they have more things to obtain and use, and they have wider knowledge and information channels.
From ancient times to the present, antique collecting has been a hot spot, but no dynasty is as good as the late Ming Dynasty, the Republic of China and modern society, which pursue the ultimate in antiques.
Because in modern times, distressed antiques are really very profitable.
Therefore, in modern times, various old-fashioned methods have emerged.
On this point, Chen Wenzhe was not convinced by anyone, but his knowledge was lacking.
If you don’t understand, just learn, and if you don’t understand, ask. Of course, if you want to learn other people’s techniques, you should also reveal some of your own unique skills.
After thinking for a while, Chen Wenzhe discovered that the only high-end distressing skills he could acquire seemed to be the knowledge related to bubbles obtained from secret-color porcelain.
Just now, he talked in general terms about the breaking of bubbles and the baptism of time on porcelain after the bubble is broken.
As for the real stuff, there really isn't much.
Now, even if it is just to attract others, I would like to reply to the two old men and let them know that he is not ignorant about the distressing of the five famous kilns in the Song Dynasty.
Especially related to celadon, he is the top expert.
For example, soaking in green glaze is a term used to identify azure glaze in the Northern Song Dynasty. When this kind of porcelain is immersed in water and washed, the water will appear slightly azure, and the water will become turbid, like pulp.
It is related to soaking in yellow syrup. This is also a characteristic formed by natural aging over thousands of years. It is not caused by manpower and cannot be imitated by ordinary people.
There are also bubble pits. The air in the bubbles in the Jun kiln glaze escapes due to the high temperature, and then the glaze shrinks, leaving a small pit in the center of the shrunk glaze, which is called "bubble pit".
In addition, orange peel lines are composed of several small bubble pits, which are obviously different from bubble eyes.
Then there are bubble eyes, which are formed during firing in the kiln. The air inside the bubble escapes, but the glaze surface does not shrink. It has a small round mouth on the outside and a large spherical hole on the inside. It is obviously different from bubble pits, glaze shrinkage holes, and glaze brown shrinkage.
Eye.
The bubble eyes, shrunk glaze air eyes, and shrunk glaze brown eyes of ancient porcelain are pitch black inside, and a small part of them are bronze.
Besides, glaze shrinkage air holes are formed during firing in the kiln. The air in the bubbles escapes, and then the glaze surface shrinks.
It has a small round mouth on the outside and a large spherical hole on the inside.
What is different from bubble eyes is that there is obvious glaze shrinkage around the outer opening.
The shrinkage glaze holes of ancient porcelain are dark inside, or show winter melon frost on the outside, or small yellow spots on the outside. If the holes are larger, traces of centuries of age can be found.
In addition to glaze shrinkage air holes, glaze shrinkage brown holes, and glaze shrinkage holes, there are also glaze shrinkage holes. These are also fired in the kiln. There are flammable substances or vaporizable solids in the body, which disappear when exposed to fire, and then the glaze surface shrinks, and other
The interior is hollow and amorphous, and the interior is pitch black.
There is a clear difference from brown eyes, which have a coral stone scene inside.
Finally, Chen Wenzhe talked about bubble bubble eyes, which is a common phenomenon in Jun kilns.
The large bubbles under the glaze have been corroded and weathered for thousands of years, and the thin glaze in the center of the bubbles burst first.
It shows spherical holes. The holes in ancient porcelain are dark, with smelly dry black often gathering inside, or traces of centuries-old traces getting into them.
This time Chen Wenzhe spoke in detail and in depth. If you don’t understand, you really don’t understand.
The two old men were not ashamed to ask. They vomited something useful just now, and this time Chen Wenzhe finally vomited it too. How could they give up?
Therefore, Chen Wenzhe next explained the formation of bubbles and brown eyes.
One of the characteristics involved is burnt lime.
In fact, this is a kind of kiln burning. He is still somewhat afraid of other issues, thinking that the two old people may be better than him.
But when it came to burning kilns, he really didn't fear anyone.
Overburned lime means that when limestone encounters high temperatures, it will be burned into a molten state. It is not white, but blue-black, and will not dissolve when placed in water for three days.
If the tire contains burnt lime particles, it will not explode when exposed to water after leaving the kiln. It will take decades or hundreds of years for the tire to expand, causing the tire body to burst.
Due to the size and depth of the particles, there are theories of fried porcelain, fried thread, and brown-eyed fried buns.
The term "brown eye" is very confusing. In Chen Wenzhe's understanding, it means that the surface of ancient porcelain is mixed with small particles and burnt lime. After weathering for a long time, it expands. Because it is on the surface, it does not explode the porcelain, but gradually washes away from the glaze.
The small eye runs out and forms a hollow, which is called a brown eye.
For counterfeiters, new traces can be seen through holes.
The cracked lines are caused by the fact that the tires contain small particles of burnt lime, which expand and have limited strength. Only one or a few lines can be blown out. You can tell where the burnt lime is by looking at the lines.
Exploded porcelain is caused by the large particles of burnt lime contained in the body, which expands and explodes the porcelain.
It usually explodes into large cracks and rarely breaks.
Theoretically, the process of exploding porcelain is a slow process that takes decades or hundreds of years.
This phenomenon is definitely not easy to imitate, and Chen Wenzhe has never heard of imitation.
Chen Wenzhe explained all kinds of secrets. If you are not really knowledgeable, you will be confused immediately, so don’t say you understand.
Obviously, the two old men did not understand this knowledge very well, but they could understand it.
Although they didn't say how to make these old, they knew that they were real goods.
Since Chen Wenzhe said something useful, they didn't mind reciprocating the favor.
At this time, some of the knowledge they mentioned really entered Chen Wenzhe's knowledge blind spot.
For example, Chen Wenzhe never paid special attention to the glass glue on porcelain, let alone imitation.
Glass glue was formerly known as old bone glue. It is a type of ancient porcelain with a glaze that has become silicone and is slightly water-soluble.
New porcelain also has silicone glue, but after three cleanings, it is gone.
As for ancient porcelain, no matter how many times it is cleaned, it will still be there.
The characteristic of glass glue has always been with ancient porcelain until the glaze is completely weathered, peeled off and disintegrated.
Check at any time and feel at any time.
Testing the perceptual glass glue is also an important means of identifying ancient porcelain.
According to Lao Zhou, no one has noticed this method of identification and aging, and no one has copied or aged it based on this feature.
How is this possible? Jingzhen has noticed it and has studied it so thoroughly, so they will tolerate it without using it?
