In order to produce a beautiful glaze color, each glaze is often composed of more than a dozen ores.
Among them, the composition of glaze chemical elements is extremely complex, especially the trace elements in it are even more unpredictable.
These uncertain factors make it extremely difficult to produce colored glazed porcelain and the yield is very low.
The cost is very high, and most people dare not try it easily.
This technique has been discontinued many times in history, and even experienced craftsmen can generally only fire one or two glaze colors.
It is like a living thing, changing all the time.
The intervention of modern technology can help us understand it and adapt to it, but there is no way to fully control it.
This is the firing color glaze,
To be precise, it is the difficulty of Liuxiazhan.
If Chen Wenzhe is asked to make it, he can easily make copper-red glazed porcelain.
but,
He can't guarantee that he will be able to produce the effect of Liuxia Zhan, this also needs to be tried and tested.
After all, it is a Liuxia lamp. As the name suggests, the red glaze on it is like flowing clouds, and some are like a peacock spreading its tail, like a chrysanthemum, etc., etc., etc., etc., these are all uncontrollable.
However, no matter what, it is beautiful, very beautiful, otherwise it would not have become a treasure as soon as it appeared.
Chen Wenzhe can easily bake copper-red glaze single-color porcelain, but it is not easy to achieve the beautiful effect of a Liuxia lamp.
But with the Pearl of Sui Hou, everything became different. He could directly learn the craftsmanship of Master Deng Xiping.
actually,
Now he can not only learn the skills of Master Deng alone.
The Pearl of Sui Marquis is different now.
Now that we can learn from Master Deng’s techniques, what about the techniques of other modern masters?
After searching, I found it inside the Pearl of Sui Hou.
It's just that he doesn't have time to study now. After all, none of the modern masters are simple.
Their techniques are not so easy to learn.
The most important thing is that their techniques require practice!
Now Chen Wenzhe is busy enough, and he doesn't want to continue to open up new shows.
Now that you have learned the technology, you must do it.
You will know if you can succeed or not by firing it.
At this time, Chen Wenzhe's studio was filled with clay, glazes, porcelain bodies, etc.
He picked up a clay cup embryo with his left hand and skillfully applied the glaze with a brush in his right hand.
Doing this kind of work is not only hard and tiring, but the working environment is also bad.
The main reason is that the production process of these porcelains is complicated. The ancients said that "seventy-two hands are used to make the pots."
He wants to start by looking for raw ore,
Then go to the glaze formula, glaze application, and firing.
During this period, there are actually far more than 72 processes, and each process also contains sub-processes, but the fun can only be experienced by those who are immersed in it.
The glaze looks inconspicuous, just like lime mortar, but different formulas can produce completely different things, ever-changing.
The glaze-coated cup looks uneven, but when fired at a high temperature of 1370 degrees Celsius, it becomes fluid.
When I finally came out of the kiln, I saw that this one was red, that one was blue, and the ugly duckling had turned into a white swan!
In this small space filled with bottles and cans, Chen Wenzhe operated skillfully.
On the ground at the door of his studio, there are many finished products.
The reason why they are placed outside is because they are all burned out.
The formula is the same, the people applying the glaze are the same, and the kilns are the same, but even if all the preliminary steps are done, nearly a quarter of the things will still burn out.
This is the difficulty of firing copper-red glaze porcelain. With such a high failure rate, most people really cannot afford it.
Therefore, to do this business, your heart must be particularly strong.
Like Chen Wenzhe, he has very high requirements for porcelain and has a higher rework rate.
If the tire is burned out, it will turn into porcelain shards.
There are both surprises of success and failure.
If it's burned out, you should study it, find out where the problem lies, and solve the problem.
Some tires are not damaged and can be reheated.
Some people say that color glaze is "the most mysterious work of art".
It is unique and cannot be copied.
To fire a perfect high-temperature color glaze work not only requires the producer to have a deep understanding of the natural properties of the glaze and blank, but also requires the producer to have adequate control over the kiln fire.
The secret glaze Liuxia lamp is really like this. If it is successfully fired, the effect will definitely make all your efforts worthwhile.
Especially after seeing the radiant, dreamlike effect.
Viewed from different angles, the light spots in the lamp are multi-layered, as if there is a pool of water floating in the air.
At this moment, Chen Wenzhe thought of the secret-color porcelain lotus petal bowl in his hand. Where is it?
It's like there is water. Is it normal to say that? It just feels normal?
Only when you actually see the original will you be shocked.
The secret color porcelain piece by Chen Wenzhe is a tall lotus petal bowl with celadon glaze. One-third of the bowl looks like there is water.
"That bowl of water moves and moves, it's so magical!"
After constantly pondering and trial-making, it took Chen Wenzhe half a month to make something that could be seen.
Of course, it is not a secret-color porcelain or Liuxia lamp, but a secret-color glaze Liuxia lamp.
What kind of effect does the combination of the two produce?
It was the color of magma and smelled a bit like water, but it was not successful yet.
Especially the flowing clouds that flow like water are not expressed.
This requires making kiln-turned red glazed porcelain that has a radiating flow feeling.
In other words, the red glaze inside the bowl needs to be like a colorful cloud radiating brilliant light, and it also needs to have a flowing feeling, which is really not easy to achieve.
In order to create the feeling of flowing clouds and a flowing form, Chen Wenzhe tried many times based on Master Deng's technique.
Unexpectedly, it actually felt like water!
I wanted to make the pattern flow, but I didn’t expect the effect of water!
Moreover, the water surface is very high, higher than the secret porcelain he made back then!
With this success, Chen Wenzhe really touched the threshold.
Therefore, in the following days, he not only learned how to make the Liuxia lamp, he was also able to combine it with secret color porcelain to make a real secret color glaze Liuxia lamp.
After that, his craftsmanship was out of control, and he successively produced many classic porcelains, especially some modern porcelains created and fired by Master Deng Xiping.
Of course, what Chen Wenzhe gained during this period was far more than this.
Because Master Deng also successfully trial-produced "lead-free Jun Red Glaze" in 1976.
This completely eliminates the risk of lead poisoning for color glaze practitioners.
In addition to this basic craft, there is also the "new formula of Dadalang red glaze".
In the firewood kiln, he successfully fired an extra-large piece of Langhong product for the first time.
It is a 62-centimeter-high "300 pieces of red-glazed beauty shoulder vases". These works have been selected as state gifts for state elders on their visits many times.
There is also a new kiln transformation process of "hidden flowers under the glaze" developed in 1982, and new kiln transformation glazes such as Phoenix Cloth Glaze and Feather Silk Glaze were developed.
