Chapter 1062: Elegance, beauty, elegance and purity
This twelve-color chrysanthemum petal plate, in addition to the previously fired ones, also has the orthodox Yongzheng color numbers, namely sauce color, indigo blue, shadow green, delicate yellow, iron embroidery, and sacrificial blue.
Among them, the more special one is sauce color, which is purple gold glaze.
Sauce glaze, also known as: "persimmon glaze, purple gold glaze", is a high-temperature colored glaze using iron as the coloring agent. The total content of iron oxide and ferrous oxide in the glaze is relatively high, reaching more than 5%.
The emergence of sauce glaze originated in the northern kilns of the Northern Song Dynasty. It was fired in kilns such as Ding Kiln and Yaozhou Kiln. Ding kiln sauce glaze is the most famous.
Cao Zhao of the Ming Dynasty stated in "Ge Gu Yao Lun" that "there are purple dyes that are purple, black dyes that are as black as lacquer, and soil that is white, and its price is higher than white dyes."
The so-called Ziding is not purple, its glaze is brownish-red, which is actually similar in color to today's sesame paste, hence its name.
This is another kind of metallic glaze that requires special attention when firing. There is another one, which is rust color.
The rust-colored chrysanthemum petal plate, due to the special characteristics of the traditional rust glaze, the rust glaze develops color by flowing during firing.
Therefore, during the firing process, the foot drop phenomenon will be formed, making the edges of the bottom feet appear to have a certain sense of staggeredness, which is natural and flexible. This is not a quality problem.
A truly complete set of imitation single-color glaze chrysanthemum petal plates must naturally have unified specifications.
First decide on the color, then unify the size, and all of this is actually based on standards.
The Yongzheng twelve-color chrysanthemum petal dish in the Qing Palace collection is the best among the Yongzheng glazed chrysanthemum petal dishes.
A set of twelve pieces, with an open plate, curved walls and circle feet.
The height of each chrysanthemum disc is 3.3 cm, the diameter is 17.8 cm, and the full diameter is 1.3 cm.
The whole body is chrysanthemum petals, with twelve colors including yellow, red, blue, green, purple, white, sauce and lotus root.
Most of the circles have white glaze, and there are blue and white double circles with six characters in regular script "Made in the Yongzheng Year of the Qing Dynasty".
A few of the ring feet are filled with glaze, and some have a double-circle six-character regular script inscription "Made in the Yongzheng Year of the Qing Dynasty" engraved under the glaze.
These chrysanthemum petal plates are rich in color, the glaze is shiny, and the chrysanthemum petal ridges are tough and powerful.
To imitate it well, it must reflect the elegance, elegance, refinement and purity of the Yongzheng official kiln color glaze porcelain.
After thinking about it for a while, Chen Wenzhe decided to start with the simplest one.
If it is cooked first, then make the yellow glaze plate first. Among the Yongzheng chrysanthemum petal plates, there are four pieces in the yellow glaze series.
Because "Huang" has the same pronunciation as "Huang", it was the supreme color in the courts of the Ming and Qing dynasties.
Most of the palace roofs, the emperor's robes, and the plates, bowls, cups, dishes and other dining utensils used by the emperor and queen for daily meals are all made of yellow.
Chen Wenzhe has never let go of the yellow glaze of the Qing Dynasty before, but he has made the yellow glaze of the Ming Dynasty.
To be honest, the real high-temperature yellow color on porcelain appeared during the Xuande period of the Ming Dynasty.
Since then, yellow-glazed porcelain has become the largest single-color glaze product in Jingzhen during the Ming and Qing Dynasties.
The main coloring agent of yellow glaze is antimony oxide. During the Yongzheng period, different amounts of iron were added to antimony oxide to produce rich changes in color tone.
In addition to yellow glaze, there are several colors such as delicate yellow (watered yellow), bright yellow, turmeric, tan yellow, beige, honey yellow, eel yellow, etc.
The bright yellow glaze in this set of twelve-color chrysanthemum petals is yellow with green in it, which is bright and dazzling;
Turmeric glaze, deep color, solid and steady;
The beige glaze is yellow with a hint of pink, and the color is soft.
It is not easy to prepare several suitable characteristic yellow glazes from so many yellow glazes, not to mention making the characteristics of these characteristic yellow glazes more obvious.
Think about it, it's just a bright yellow glaze with a hint of green in the yellow, which is not easy to bake.
Fortunately, he had tried burning it before, which made Chen Wenzhe understand that the inheritance experience he had learned through the Sui Marquis Pearl was very useful and correct.
Therefore, I don’t have to worry too much when preparing the glaze. As long as the porcelain he fires is generally not too bad, if it doesn’t work and the desired effect cannot be achieved, the worst thing is to adjust the formula and fire more
Several times, he has time now anyway.
So to be on the safe side, he still had to make a few more.
This time, he mixed all the yellow glazes he could think of, and after they were all fired successfully, he selected the most beautiful ones to form a set.
After finishing the yellow glaze chrysanthemum petal plate, I am now making the white glaze.
Among the Yongzheng chrysanthemum petals, there is a white glazed chrysanthemum petal plate, which is fine, white and moist, as white as gelatin.
White glaze is the natural glaze of porcelain and is generally considered to be the easiest to control, but this is not the case.
Because all porcelain clays and glazes contain some iron oxide to a greater or lesser extent.
After firing, it will appear a darker or lighter cyan tone.
The iron element in the glaze must be reduced to less than 0.75%o in order to burn pure white.
The white glaze of the Yongzheng period did not add any coloring agent. It just reduced the iron in the body and glaze to the minimum, and then applied a layer of high-quality transparent glaze. It completely relied on the whiteness of the body soil itself to present the white color.
The purity of the white glaze porcelain soil is very high. A little impurity will affect the purity of the glaze.
The process that Chen Wenzhe least worries about and is the most worry-free is tire soil, because many modern mud factories can prepare perfect tire soil according to his needs.
Therefore, as long as you grasp the color well, it is not difficult to make white porcelain.
"We need to make some changes, and we need to be more careful."
After making the white porcelain, Chen Wenzhe felt that he needed something more difficult, so this time he chose to mix a rouge purple glaze.
Among the chrysanthemum petals of Yongzheng, there is a rouge purple glaze dish, which is as bright as rouge.
This kind of rouge purple glaze is a red-pink low-temperature glaze with gold as the coloring agent introduced from the West during the Kangxi period of the Qing Dynasty.
During the Yongzheng period, it developed to the extreme, with two types: deep and light. The lighter one is almost pink, commonly known as rouge water.
The darker one is close to rose red, commonly known as rouge purple.
The glaze on this plate is deep, delicate, smooth and even, and is deeper and more purple than the rouge water glaze.
The rouge water or rouge purple glaze of the Qing Dynasty was all official kiln porcelain. Because of its scarcity, it was extremely valuable.
Chen Wenzhe has done this a lot, and it is not difficult to make. Even when it is fired in the kiln, Chen Wenzhe is not worried about making mistakes, so he does not make more.
Next is the green glaze plate. There are three pieces in the chrysanthemum petal plate that belong to the green glaze series, the green glaze chrysanthemum petal plate, the emerald green glaze chrysanthemum petal plate, and the lake green glaze chrysanthemum petal plate.
Copper metal will take on a green hue in the oxidizing atmosphere. In the middle of the Ming Dynasty, Jingzhen produced bright low-temperature green glazes.
However, since the glaze is applied directly on the unglazed blank, the cleanliness of the glaze is poor, and the small impurity particles in the tire are clearly visible.
During the Yongzheng period, on the basis of inheriting the copper-green glaze of the previous generation, various green-glazed porcelains mixed with other metal colorants were developed.
Therefore, during that period, there were not only ordinary green glazes, but also new glaze colors such as caviar green, turquoise green, melon skin green, lake green, emerald green, and turtle skirt green.
The purity of the green glaze has also been greatly improved, the color is bright and green, clean and transparent.
The green glaze plate in the chrysanthemum petal plate has a thick green and bluish glaze with no grain;
The glaze color of the scallion green glaze plate is green with flashes of yellow, close to grass green, just like the young green onions in the early buds, bright and delicate:
The color of the lake green glaze plate is elegant and sky blue, soft as silk, moist and bright.
Chen Wenzhe has tried burning these before, and they were not difficult.
