Chapter 298 Six Kiln Changes
"The black glaze of Jian kiln belongs to the category of ancient crystalline glaze, and has a high iron content. During the high-temperature melting process, due to the change of the temperature and atmosphere in the kiln, the glaze surface produces strange patterns. These glaze patterns are in harmony with the gorgeous Different from traditional colored painting or complicated carvings, they are the result of glaze changes in a certain temperature and atmosphere. They seem to be the work of "Kiln God", which produces a special artistic charm, which is called "Kiln Transformation" in the ceramic craft circle. Because it is not done by human beings, it is more precious."

Wu Tianyuan followed everyone to study the construction of kiln kilns these days. It is very difficult, mainly because the temperature and glaze formula are difficult to master. After burning more than a dozen kilns in a week, there are very few successful kilns, and the failure rate is extremely high.

"In the past few days, we generally use the dipping method to fire the black glaze of the Jian kiln, and apply the glaze at one time, and the glaze layer is generally thick and the glaze juice is fat. Because the Jianzhan is fired in the front, the glaze layer along the mouth is relatively thin, while the other The polyglaze on the inner bottom is thicker; the outer wall is often half-glazed to avoid sticking to the bottom of the kiln; the remaining glaze is easy to flow at high temperature, so there will be glaze hanging phenomenon, commonly known as "glaze tears" and "glaze dripping beads."

Old Tang analyzed: "After the boss's secret recipe, now the glaze tears have basically been cracked, and the yield rate can reach [-]%, which is not easy!"

"However, apart from glaze tears, there are five other kiln transformations in Jian Kiln, Wujin, Variety, Rabbit Hair, Oil Drop, the most mysterious and precious Yaobian!"

Several people were lost in thought. It can be said that they have just started for a week. The most precious things in Jianyao are rabbit hair and Yaobian, both of which are national treasures in Japan.Wu Tianyuan doesn't want to be dragged down, if he wants to do it, he must do it to the extreme, and Yao Bian is the ultimate goal.

He also knows that even if all the secret recipes are deciphered, Yaobian Tianmu is still a rare treasure, more precisely, it is a gift from God to human beings!
Mr. Geng comforted: "Everyone, don't be discouraged. Our progress is already very fast. The next step is to study the black gold glaze. Some Jian kiln surfaces are as black as lacquer; Thin, plain and no grain, the glaze color of the early Jianzhan mostly belonged to this type, the glaze surface was slightly dull, black and not moist, and rarely glazed. The glaze layer of Jian kiln black gold glaze is generally thick, "black and moist", The superior ones are bright and can illuminate people, showing the beauty of solemnity and elegance."

Old Tang took out the family formula and said: "Potassium feldspar 20, quartz 12, kaolin 10, calcium carbonate 10, dolomite 10, golden red 16."

Wu Tianyuan also took out the formula he had just sorted out and said, "The front of mine is the same as yours, but talc 12 and iron oxide 15 are added in the back."

"In the afternoon, let's test the results in practice. To enter the Japanese market, there are mainly four types of kilns." Geng Lao analyzed: "Wujin glaze and glaze tears are entry-level. After all, they have a higher yield rate and are suitable for middle-class collectors. .But the rabbit hair and oil drop are high-end products, with low yield and large variables, which are the favorite of senior collectors. As for Yaobian, they are rare treasures, rare treasures that cannot be found!"

Rabbit hair is the most typical and most productive product of Jian kiln, so that people often use "rabbit hair" as a synonym for Jian.The so-called rabbit hair refers to the uniform and fine silky stripes dialyzed in the black base glaze, which is shaped like the vellus hair of a rabbit.

Due to factors such as kiln changes, the shapes of rabbit hairs can be divided into long and short, thick and thin, and the color can also change from golden yellow to silver white. They are commonly known as "golden rabbit hairs" and "silver rabbit hairs".

Song Weizong wrote in "Daguan Tea Theory": "The color of the cup is as expensive as green and black, and the one with the best jade is the best.

The oil drop is the "partridge spot" referred to in the literature of the Song Dynasty. The so-called oil drop refers to the countless small spots with golden yellow or silver gray metallic luster scattered on the black bottom glaze, so there is also the "golden oil drop". , "Silver Oil Drop".

Most of these spots are round and vary in size. The larger ones are generally three or four millimeters in diameter, and the largest ones are up to one centimeter.Those are only one millimeter, even as thin as the tip of a needle, scattered like boiling oil droplets, dazzling people.

Oil drop is also a kind of crystalline glaze, which is difficult to fire, has a low yield, and is rarely handed down or unearthed.A Southern Song Oil Drop Tianmu Bowl collected by Jingjiatang Bunko Art Museum in Japan is regarded as a national treasure.In Japanese literature records, "Yudrop" is a precious porcelain product limited to "Yaobian".In the world of modern collections, oil droplets are also rare treasures in Jianzhan.

The term "Yaobian" is recorded in "Songs of the Zen Forest". It was written in the "Juntaiguan Left and Right Accounts" in the early sixteenth century. The supreme god of Jianzhan is something that the world does not have.

The so-called Yaobian refers to the gathering of many irregular dots on the black base glaze. The dots are yellow, and the surrounding area glows with blue-based dazzling rainbow-like light, hence the name.

The obsidian spots are widely distributed on the inner wall of Jianzhan, and change with the direction of viewing. When viewed vertically, it appears blue, and when viewed obliquely, it shines golden.Due to the extreme difficulty of burning the obsidian, it is rarely handed down from generation to generation. Only four pieces are collected in Japan, three of which are designated as "national treasure" cultural relics, and one is designated as an important cultural relic.

Now Wu Tianyuan has three obsidian changes in his hand, black, blue, and dragon ball, and there is still one red obsidian change, and he has been looking for it.

A few people hurriedly finished their meal, and went back to the kiln together to continue to study the formula of Wujin glaze. Whenever Wu Tianyuan encountered a problem, he would write it down, and went back to communicate with the antique alone, looking for a breakthrough.

Thanks to the brainstorming of several top experts, in less than a month, Wujin, Rabbit Hair, and Oil Drop have all been tested successfully, and the technology has continued to mature. The next step is to mass-produce it and officially put it on the market.

"This is one hundred sets of Tianyuantang celadon, one hundred pieces of Jianyao rabbit hair and oil drops, how do you see it?"

After appreciating all the products in amazement, Yasuda said in admiration: "As expected of Mr. Tianyuan, each piece is the most exquisite antique porcelain I have ever seen, especially the Jianyao oil drop, it is simply amazing!"

Wu Tianyuan also just returned to the capital, and he has worked hard for more than a month, and has experienced the hardships of firing porcelain.I have supernatural abilities, and it is so difficult for Old Tang to inherit the craftsmanship for hundreds of years. No wonder no one has been able to imitate it successfully for hundreds of years.

Yasuda respectfully handed over a plan and introduced: "This is the cooperation intention of our Yasuda family. It is mainly to use the channels and influence of the consortium to cooperate with Tianyuan Jun. The pricing is unified according to different levels. Of course, you can choose the best one yourself. Auction, in the end you eight and I two!"

"Oh?" Wu Tianyuan was taken aback, and asked curiously, "Do you agree with this share ratio?"

Yasuda Zhengse promised: "Don't worry, this is the result of my persistent efforts! Originally, it was [-]-[-], but in order to show the sincerity of our Yasuda family and the determination of long-term cooperation, this ratio is no problem!"

Wu Tianyuan nodded, very satisfied with Yasuda's attitude, money is a trivial matter, the main reason is that now he gradually has the bargaining chip to negotiate with the big family!This is the biggest improvement and a strong start.
