As long as we can successfully bake a piece of silver rabbit hair, everything will be fine in the future.
If there is one, there are two. I am afraid that even one will not be fired successfully.
As long as you have the first one, it means you are on the right path.
As long as you do more, as much as you want, and accumulate more experience, and your temperature control will become more and more accurate, you will have more and more successful works in the future.
After that, even if there are not many successes in one kiln,
Even if there are only a few pieces, it is still a success.
Besides, he doesn't need to bake them in large quantities. If one kiln can successfully fire one or two pieces, it is already very impressive.
This is the difficulty in controlling kiln changes. The time between firing and failure is often only a few seconds, which is too difficult to grasp.
Fortunately, modern technology and equipment are very powerful. Although it is still impossible to accurately grasp the firing atmosphere, it is still possible to detect the conditions in the kiln.
As long as it is detected, the firing conditions are about to be reached, and manual intervention at this time will have a higher success rate.
After all, Chen Wenzhe's kiln-firing skills are not just for show.
Therefore, the process of re-burning the silver rabbit hair is not as difficult as thinking about it.
However, among the rabbit hair lamps, the exquisite ones are not just silver rabbit hair.
When firing silver rabbit hair, sometimes the temperature in the kiln is not accurately controlled, but other rabbit hair cups, or even oil drop cups, can be accidentally fired.
Let me briefly mention oil droplets here. The mechanism of oil droplet formation can be summarized as the duckweed mechanism.
When fired to about 1300°C, under specific physical and chemical conditions, the glaze begins to form a liquid phase separation structure.
The main phase of the glaze separates into another phase rich in iron.
Under the action of gravity and surface tension,
The iron-rich phase easily floats on the glaze surface. As the process goes on, more and more iron-rich phases float on the glaze surface.
The liquid phase droplets formed by these iron-rich phases are like green duckweed floating on the water surface and can float on the liquid surface.
They meet randomly, in small groups, and form packages of different sizes.
The larger the package group, the more liquid phase droplets there are, but these liquid phase droplets are only close together.
At this time, these droplets did not melt into one, just like leaves of green leaves leaning together.
When the firing reaches a certain level, the temperature is lowered and cooled.
During the cooling process, when the environmental conditions are suitable for crystallization of the iron oxide in the package mass, a kiln-building oil droplet is formed.
Therefore, the oil drop cup is formed at the last critical moment. Of course, the firing temperature and changes in glaze are also key.
No matter what, as long as you can make a rabbit hair cup and grasp a few key points,
You will definitely be able to make an oil dripping cup.
And in the last-minute changes, the oil droplets can also be divided into several categories.
For example, gold oil droplets, blue silver oil droplets, red oil droplets, iridescent oil droplets, etc.
In this way, things become more amazing, because colors such as gold, blue, silver, red, and iridescence appear here.
So can we also get these glaze colors by burning paper rabbit hair lamps?
In fact, the colors of various porcelains are related to each other, just like the iridescence. If it is slightly changed and a needle-shaped scene is fired that radiates like a rainbow, wouldn't this be a Liuxia lamp?
And the radiating patterns on the Liuxia lamp are just like rabbit hairs?
Among the porcelains here, only the kiln-changed patterns inside the lamps are different. For example, the oil drop lamp appears because small oil droplets appear in the inner glaze layer.
The rabbit hair cup is because after the firing is successful, the scene inside the bowl is like needle-shaped radiating lines of various colors like rabbit hair.
Although the appearance of the two kiln changes is different, they are both fired with the same material. If the temperature and cooling are well controlled, the glaze color formed by the oil drop cup and the rabbit hair cup can also be achieved. After all, they are all colored by iron.
By this time, Chen Wenzhe had more ideas about the firing of the kiln, or the control of temperature control.
As time went by, he learned more and more about rabbit hair.
There are just a few shapes. To be honest, the shape of rabbit hair can be divided into length, thickness, etc., and the color can be gold, silver, etc.!
Even more rare, the most difficult to obtain is probably the blue rabbit hair.
If we could summarize it more comprehensively, there would be quite a lot of colors in Tuhao Jianzhan.
The classic colors of rabbit hair can be divided into gold rabbit hair, silver rabbit hair, blue rabbit hair, green rabbit hair, yellow rabbit hair, red rabbit hair, etc.
Among them, silver rabbit hair or silver blue rabbit hair are relatively rare and difficult to bake, so they are often more precious than rabbit hair of other colors.
But this is not absolute. It depends on key parameters such as the uniformity and density of the texture, as well as the clarity of the texture.
To judge the value of a rabbit halo jianzhan, you cannot blindly judge based on the color.
Generally, it is not difficult to bake rabbit hair lamps. For example, it is not difficult to bake yellow rabbit hair, green tuhao, and red rabbit hair.
These colors are all colored by iron elements. When firing other precious rabbit hairs, if the temperature is not controlled properly, rabbit hair lamps of these three colors may be produced.
Therefore, the most difficult thing to bake is silver rabbit hair. On this basis, if you don't grasp it accurately again, you can accidentally bake gold rabbit hair, yellow rabbit hair, etc.
If you have fired silver rabbit hair, you can go one step further and bake blue light silver rabbit hair.
Anyone who knows a little bit about the art should know that if the crystal is fired, the precipitation process will be more unstable, so it can be said that this kind of crystal is difficult to fire.
Therefore, it can be said that silver-based markings are more precious than brown-based markings. If silver has blue light, it is even more rare.
And it doesn't seem too difficult to achieve this effect.
Of course, this is something that difficult people don’t do.
In ancient times, it was impossible to understand the underlying principles. It was like a blind man touching an elephant. Naturally, he could only try his luck.
But modern people are different. As long as they understand the distance and restore specific kiln changes, it is not too difficult.
This is for Chen Wenzhe. Without solid skills and a strong foundation, no matter what kind of kiln-shaped porcelain is fired, it will be difficult.
At this time, he has been able to control the firing of rabbit hair lamps. Even if there are some rare kiln changes, he can have a high probability of controlling the kiln changes.
This is more powerful, but he can really do it.
At the very least, after firing in a few kilns, one or two pieces of blue rabbit hair can be successfully fired.
The reason here is also very simple. If the reducing atmosphere in the kiln is strong, the content of magnetite crystals in the rabbit lines will be higher.
At this time, the crystal size is larger and grows parallel to the glaze surface, giving it a strong metallic luster and forming silver rabbit hairs;
If the oxidizing atmosphere in the kiln is strong during firing and the content of hematite crystals in the rabbit lines is high, two situations will occur.
If the crystal size is small and grows randomly without reflecting light, yellow rabbit hair will be formed;
If the crystal size is large, grows parallel to the glaze surface, and has a strong metallic luster, golden rabbit hair will be formed.
In other words, even if you fail to make silver rabbit hair, you may be lucky enough to get yellow rabbit hair, and if you are even luckier, you may get gold rabbit hair.
Therefore, even if you have a thorough understanding of the zhanzhan-firing process, sometimes it still depends on luck.
