Riding the wind of rebirth

Chapter 575
This is not bad. The main reason for the five colors of Jun kiln is the reduction reaction of copper atoms in the glaze, which can make the glaze color complete the rich color kiln change from red, purple to blue and green, forming a "one color in the kiln, The magical change of "every color out of the kiln".

From this point of view, the coloring of cowpea red in the Qing Dynasty was actually determined by the reduction reaction of copper ions. Although the variation is not as rich as that of Jun kiln, it is consistent in terms of the principle of glaze color.

However, the copper ions in the glaze of cowpea red are far more abundant than those of the Jun kilns of the Song Dynasty, and the fired items are basically warm-colored, with only a small number of items with green kiln changes.

Hong Liangji, a native of the Qing Dynasty, once wrote a poem praising its glaze color as "green like spring water on the first birthday, red like the morning glow." This poem is not too much to describe Jun kiln.

"If it is a serious ritual porcelain, 'Beauty Drunk' will naturally be inferior to 'Dahongpao' or 'Zhenghong'." Zhang Cheng looked at the Pomegranate Zun admiringly: "But such a kiln change happened on the Pomegranate Zun. But it is just right, even closer to the natural qualities of pomegranate in terms of aesthetics, a masterpiece created by half artificial and half natural."

"It's even better than 'Dahongpao' or 'Zhenghong'."

Then I looked at the bottom, but couldn't help frowning: "Why is it so dirty? The bottom line is all muddy?"

"It looks like old wax paint, or it was burnt and scratched by the brats at home, but it hasn't been cleaned up yet." Zhou Zhi played up his association.

Zhang Cheng was terrified when he heard that, and shook his head involuntarily: "Violence, violence..."

"Why don't we take a gamble?" Old Chai's mischievous energy came up again.

"What are you betting on?" Zhang Cheng asked casually, but his eyes still couldn't leave the pomegranate statue.

"Bet on whether there is a model for this porcelain, and if so, what year is it?"

Seeing Zhang Cheng look up at him, Lao Chai hastily added: "You and Elbow guess, let's buy a horse!"

"We are being tested." Lao Zhang joked with a smile: "In your eyes, I am afraid that you regard it as a modern Jun kiln?"

"Which generation do you think Elbow is from?"

"Actually, there is nothing to break. The shape of the utensil is light and beautiful, the tire is repaired regularly, and the enamel is even and bright." Zhou Zhi said with a smile: "In addition, the real formula of cowpea red glaze has been lost in the Kangxi Dynasty. The color changes caused by the uneven reduction state, the glaze is basically too thick, and the aura of "beauty drunk" is lost."

"This pomegranate statue is generally in line with the characteristics of the Kangxi dynasty's thin body and thin glaze. I guess it belongs to the Kangxi dynasty."

"I still have to look at the opening piece." Lao Zhang took out a magnifying glass for repairing watches from the counter and put it on his eyes, and carefully looked at the small opening piece on the pomegranate statue with the sunlight: "Well, it is indeed the Kangxi dynasty. Characteristics."

After taking off the magnifying glass, seeing that Zhou Zhi had already adjusted the reagents, he looked at him eagerly, and couldn't help but smile, "I can barely see it now, but if it's under the light of the flashlight in the middle of the night, I definitely wouldn't dare to make a move."

After speaking, he reached out to touch the pair of bottles: "But if you miss this, you shouldn't..."

"Hahahaha..." Old Chai was as happy as if he had picked up a treasure: "You just bullied us for our lack of skill. I didn't expect that today an expert came and kept Elbow busy while we started classes!"

"Isn't that a trick?" Zhang Cheng seemed to have a good personality.

"Don't say that, Uncle Zhang, I want to hear it too. Why are you so interested in Chongzhen blue and white flowers?"

"Okay, then I'll talk about it." Zhang Cheng poured tea for everyone again: "During the Chongzhen period, the power of the Ming Dynasty had seriously declined, and Jingde's official kilns were in a state of disuse, and only private kilns continued to be produced. To produce porcelain, it needs to be customized with folk kilns, which is the famous "official and private firing" system in the history of ceramics."

"At that time, folk kiln porcelain was exported in large quantities, but the quality of porcelain production declined significantly. Judging from the history of porcelain production in the Ming and Qing Dynasties, the Chongzhen blue and white porcelain was at its lowest point from the late Wanli period to the early Kangxi period in the Qing Dynasty. The biggest manifestation is the tire making."

"Chongzhen blue-and-white is made of kaolin, and the tire quality is mostly rough and loose. The tire color is off-white. The carcass is generally thicker. The glaze layer is thin, the glaze surface is uneven, the gloss is not strong, the glaze color is white and blue, and there are also blue-gray. There's even a film."

"In order to cover up the shortcomings, it was popular at that time to apply a circle of caramel-colored glaze on the edge of the utensils. The ring feet are generally designed to be short, which is to visually block the exposed tires at the bottom."

"There are many turnings on the outer edge of the line, and there are deep digging marks on the inner wall of the foot wall of the large bowl ring, which is called "two-story platform" in the jargon. Turned small table, kiln slag, chicken heart protruding."

"These are the traces left after the tire was turned and repaired for the second time. It shows that Jingde has seriously regressed in the clay molding process during this period. Heavy machinery is better than heavy handwork in tire making. Obviously it is In order to meet the needs of large-scale folk firing."

"The blue and white pigment of this period is Shiziqing, which is a bit stable in color, but its weakness is that the blue and white with the best free color can be bright and green, and most of them are affected by the fineness of the process, resulting in color changes. It's dim, and it also has the phenomenon of dizziness like Su material."

"Severe haloing even affects the decoration, causing the lines of the decoration to be confused. This puts forward strict requirements for the painter, requiring more detailed strokes and more accurate coloring."

"However, except for a small number of high-quality goods, most craftsmen's craftsmanship is not so superb, so the painting is often painted too lightly, resulting in glaze leakage. Some of them are painted too thickly, resulting in dark brown spots in the blue and white."

"However, unlike the color of Soviet materials in the Yuan Dynasty and early Ming Dynasty, the black spots of Shi Ziqing do not penetrate into the fetal bone, and there is no unevenness in the hand."

"But although Chongzhen blue and white has such and other shortcomings, it also has advantages that the blue and white peaks of the two successive times did not have, that is, the subject matter and the use of brushwork."

"Because of the loss of the prohibition of official kiln creation, the craftsmen of the Chongzhen Dynasty completely let go of themselves, and created a brush-point brush similar to the light ink and color in Chinese painting, using a large number of deformation, exaggeration or simple brushwork techniques, and the picture is bold and unconstrained. Restrained, very poetic."

"The subject matter has also become very broad and rich in content. Literati landscape painting has become the most common subject matter in this period, and the painting has the charm of traditional Chinese painting in the late Ming Dynasty."

"There are many ancient poems in the picture, and the content is very lifelike. Thatched huts, thatched pavilions, boat bridges, fishermen, woodcutters, high scholars, literati, historical allusions, legends of gods and monsters, opera stories, etc., all became decorations during this period. theme."

Lao Zhang is definitely a master. Zhou Zhi dipped his brush in this organic solvent to paint the primer of Pomegranate Zun, and listened to his explanation, nodding secretly in his heart.

People in the world are so easy to follow suit. When it comes to blue and white porcelain, it was either Yongxuan of the Ming Dynasty or the third generation of the Qing Dynasty.

Chongzhen blue and white, as an important era in the "transition period", did not get its due status until many years later.

The reason is that the general collectors do not have enough research on the category of blue and white porcelain, and the collectors only recognize "annual date" and all porcelains that are not "annual date" and famous base models are classified as "folk kiln porcelain". ", in fact, was dragged down by a large number of shoddy works.

But the Zhang Cheng in front of him can see the value of Chongzhen blue and white among all the collectors, knows how to think independently, and can comment so well. This attitude of making a living as a real study of learning has been recognized by Zhou Zhi.
