My system is not decent

At that time, the price of a fragment of kiln construction was 300 yuan.

You know, at that time, I was still earning work points, and my monthly income was only a few yuan, and 300 yuan was already quite expensive.

Therefore, Chen Wenzhe believes that no matter who encounters this matter, they will deal with it in a low-key manner.

Collectors are often most afraid of others knowing that he has rare treasures, especially in the two local villages, where there have been many stolen Jianzhan collections over the years, and it is impossible to investigate and deal with them.

In fact, it is rumored that there should be quite a few obsidian fragments that have been unearthed.

Of course, it is not ruled out that there are still some fragments of Yaobianzhan in the hands of collectors who collect Jianzhan.

In addition to reports in 2017 that obsidian fragments were unearthed in Hangzhou, a collector in Kunming has been displaying the complete "obianzhan" in his collection.

At the same time, neon also has a controversial lamp.

Some people believe that it is the fifth Yaobianzhan.

These lamps, no matter whether they are Yaobianzhan or not, even if they are finally approved, they can't change the fact that Jianzhan Yaobianzhan is, that is, Yaobianzhan is really very rare!

Why are there so few obsidian lamps?This point has long been discussed by domestic Jianzhan production masters.

The formation of the obsidian variable lamp is about a one in a million probability.

Why so few?The reason should be that the technology is too difficult.

In industry terms, it was an accident at the right time and place.

It is a technology with no standards, no answers, and no way to control it.

Modern firing is difficult. If you want one, or even take a look, you have to go to Neon to see it?This makes people more aggrieved!

Aren't you going to be a baby?Then I will burn some more, even more beautiful than those three ancient ones.

However, it is not easy to achieve this.

First of all, you must first understand, what is Yaobian?

The word "Yaochang" first appeared in the Wanli period of Ming Dynasty, which originally meant "kiln change".

Documents of the Neon Muromachi Era" "Juntaiguan Left and Right Bookkeeping" records: "It is rumored that the kiln was first opened... Yaobian".

Jianzhan, to put it bluntly, is a small tea bowl used by people in the Song Dynasty to fight tea. Why do people like it in ancient and modern times?

That's because the kiln in Jianzhan becomes Tianmu, which is really beautiful.

Neon people describe this bowl with the words "the universe in the bowl", saying that it looks like the starry sky seen by the seaside at night, which is unpredictable.

Indeed, the pattern of this bowl due to natural kiln changes is like being on the seashore in the middle of the night and seeing the bright starry sky.

And there are thousands of mysteries hidden deep in the starry sky, just like an unknowable vast universe.

The reason why this bowl is said to be a unparalleled treasure is that if the Yaobian Tianmu tea bowl is placed in the dark, its flares will flash a slightly bewitching light, with changing colors and unfathomable depths.

Although the diameter of this tea bowl is only 12 centimeters, it can remind viewers of the universe and starry sky.

There are many opinions about the reasons for the formation of the obsidian phenomenon.

As the Japanese scholar Kazuo Yamaki put forward: "The blue glow of the obsidian change is not a factor of the glaze, but it may be caused by a layer of film on the glaze, and the blue glow is produced due to the interference of light caused by the film, just like Like an oil film on water or an anti-reflection film on a photographic perspective."

Chinese scholars have found through research that the obsidian phenomenon is due to the segregation of silicon, forming a thin film with a thickness of several thousand angstroms to 1 mm on the glaze.

The bulk of the film and the glaze are metastable phase separation and unstable phase separation respectively, thus forming interface reflection on the structure.

The optical principle of the glaze color change is that the thin film interference causes the formation of the changeable Tianmu glaze.

The process factors are mainly the composition of the glaze, firing temperature, holding time, thickness of the glaze layer and cooling speed.

Of course, even if you have mastered all these crafts, the final flare celestial eye will not be exactly the same.

As for the surviving ones, the names of the three neon are completely different.

The one in the Jingjiatang Bunko is called "Inaba Tianmu". This obsidian bowl is internationally recognized as the first bowl in the world, and it is also known as "the universe in the bowl".

However, when Koyata Iwasaki, the fourth-generation head of the Mitsubishi Group, got the cup, he repeatedly said that he was not worthy of using it.

And he has never used it to drink tea in his whole life. Why would Koyata Iwasaki have such an idea?What is the origin of this lamp?

Seikado Bunko Art Museum is located in the Setagaya district of Neon Tokyo. It was co-founded by two generations of Mitsubishi Group's second-generation president Iwasaki Yanosuke and fourth-generation president Iwasaki Koyata father and son.

It is mainly used to collect various rare ancient books. So far, the museum has collected 7 national treasures, 84 important cultural properties, and 20 ancient books.

The name of "Jingjiatang" is taken from "Qi Gao Wei He, Yan Dou Jing Jia" in "The Book of Songs·Ji Zui".

It means what kind of sacrifice to offer to the ancestors, a clean and beautiful sacrifice.

Therefore, Jingjia has the meaning of cleanliness and beauty, which should be beyond the expectations of Chinese people, right?

Up to now, how many people in China can explain this name?How many people know the Book of Songs?

Don't say you understand, how many can recite a few lines of poetry?

I'm afraid I understand, that is, I know those famous lines, right?There are not many Chinese people who have a deep understanding!

Or this Tianmu lamp, to understand it, you need to know its value.

Let’s not talk about the present, just talk about the past. At the earliest time, this thing seemed to be hidden in General Tokugawa’s house.

Later, a person named Kasuga Bureau passed on the national treasure Yaobian Tianmu Zhan obtained from the former Tokugawa General to the descendants of the Inaba family who were related to her, and named the Zhan Inaba Tianmu.

By the seventh year of Taisho (1918), the era of the shogunate had long since ended, and Inaba Tianmu was in the hands of Tetsuro Ono.

Later, in the 13th year of Taisho (1924), Tetsuro Ono sent this Yaobian Tianmu cup to the auction house, and finally sold it to the Iwasaki family, president of Mitsubishi, at a price of 16.7 yen.

Less than 17 yen, this price should be very unexpected, right?

Is it feeling too little?In fact, there is a cognitive error here.

At that time, this 16.7 yen was not the current 1 dollar more than 100 yen.

More than 100 years ago, to be precise, in 1897, the Neon Currency Act was issued, and their gold standard system was established in legal form for the second time.

The law states that one yen is equivalent to 750 milligrams of gold.

That is to say, the 16.7 yen at that time was equivalent to 125.25 kilograms of gold, worth nearly 4000 million yuan, or 700 million U.S. dollars.

Converted at today's exchange rate, it is worth [-] billion yen.

There is no doubt that this was an astronomical figure at the time.

The biggest reason why this yaochang lamp in the Jingjiatang Art Museum has such charm is due to its unpredictable glaze color.

The real thing is as dark as lacquer, but at the same time it is extremely deep and full of changes.

On top of the deep black basic tonality, colored spots with blue as the main color and crystals with metallic luster are added. The combination of all these makes people who see the flare in the bowl really feel like seeing a starry sky.
