Classic porcelain with overglaze colors include plates with red clouds and dragons on a green ground, three-color bottles with plums and magpies on a yellow ground, etc.
These colored porcelains are generally official kiln porcelain from the Qing Dynasty.
This is overglaze color and underglaze color. The third major category of porcelain glaze color is overglaze and underglaze mixed color.
Underglaze color and overglaze color are used at the same time. To be more precise, it is a combination of underglaze blue and white and overglaze color.
For example, blue and white doucai, referred to as doucai or "doucai", first appeared in Xuande of Ming Dynasty and matured in Chenghua of Ming Dynasty.
Not all blue and white overglaze colors can be called doucai.
The key is that the outline of the pattern must be outlined with blue and white on the carcass. After the porcelain is fired, various overglaze pigments are filled in the outline as needed.
Throughout the process, blue and white play a leading role.
What distinguishes it from blue and white fighting color is blue and white adding color.
If blue and white is no longer used to outline contours, but is only used as a color to express local patterns, it is called blue and white coloring.
According to the different types of overglaze colors, blue and white plus colors can be further divided into blue and white single colors.
For example, blue and white with red color, blue and white with gold color, blue and white with green color.
There are also blue and white double colors, such as blue and white, yellow and green colors, and then blue and white multi-color.
Since the 1970s, two new types of colored porcelain have become popular.
One is the glaze-in-glaze color, which can be understood as applying a layer of glaze on top of the over-glaze color.
Like plastic sealing, the painted painting is sealed between two layers of glaze.
The other is high-temperature color glaze painting. This kind of porcelain does not use color pigments, but directly paints with high-temperature color glazes of different colors, and then fires it at high temperature at once.
In fact, these are not special. Special products among colored porcelain must be different in glaze color.
Among my country's special craft porcelain, some simulated glazed porcelain can be called a unique skill in porcelain.
These imitation porcelains are almost indistinguishable from the real ones, which shows the superior craftsmanship.
And the key to all of this is actually the glaze.
Therefore, sometimes some high-quality glazes are very expensive.
For example, blue and white materials, good blue and white can cost tens of thousands per kilogram.
This is why Wu Er and others are willing to spend hundreds of millions in exchange for Chen Wenzhe.
In fact, if you calculate carefully, 100 million won't be able to exchange for much top-quality green material.
A top-notch meal costs tens of millions, or even 20 to 30 million yuan, but 100 million yuan is only equivalent to three or four tons.
With such an expensive blue and white glaze, the cost of producing blue and white porcelain is not low.
If there are still some initial problems in the production process, and even after several kilns are fired, a few fine products cannot be produced, then I will definitely go with Dafa.
It is not uncommon for such a precious glaze to be used on domestic porcelain.
For example, some domestic special porcelain requires high-quality glazes.
For example, imitation jade glaze is a new type of high-temperature colored glaze porcelain created by the Jingzhen Royal Kiln Factory during the Kangxi period of the Qing Dynasty, and continued to be fired during the Qianlong period.
Because the glaze color of this kind of porcelain is very close to the color of ancient jade, it is named imitation jade glaze.
Common utensils with imitation jade glaze are mainly in various shapes such as bottles, washbasins, and jars.
In terms of glazing, the glaze blowing method is mainly used, and the patterns flow naturally, which is very distinctive.
In terms of inscriptions, the six-character and three-line blue and white seal script inscriptions of the "Yongzheng Year System of the Qing Dynasty" are mostly used.
Or the four-character double-line seal script inscription "Yongzheng Year System" may be inscribed on it, but some utensils are not decorated with the inscription.
Then there is the imitation stone glaze, which is a new type of porcelain created during the Qianlong period of the Qing Dynasty.
Until the Republic of China, there were still works imitating the Qianlong period.
However, the color, glaze, patterns, markings and other aspects of the utensils are still quite different from the authentic ones.
The imitation stone glaze works of the Qianlong period mainly imitated the texture and color of natural stones.
If you don't identify it carefully, it is almost impossible to tell. It can be seen that the imitation is natural and lifelike, and it is lifelike.
The common shapes of utensils at this time mainly include boxes, stoves, plates, pen holders, etc., especially pen holders are more common.
Regarding glaze colors, the more common ones are marble glaze, turquoise glaze, tiger skin glaze, pebble glaze, etc.
In terms of identification of the artifacts, the four-character double-line gold-colored seal script inscription "Qianlong Year System" is mostly used, and the gold-colored color is a single-line border.
Or it is a six-character, three-line gold-colored seal script inscription "made during the Qianlong reign of the Qing Dynasty", but there is no sidebar outside the inscription.
This kind of imitation glaze color imitates various natural objects, such as jade, stone, bamboo, etc.
For example, imitation lacquer glaze is a new type of low-temperature glaze porcelain created by the Jingzhen Royal Kiln Factory during the Qianlong period of the Qing Dynasty.
Imitation lacquer glaze can generally be divided into several categories: imitation vermilion lacquer, imitation carving lacquer, imitation bamboo woven lacquer, imitation mother-of-pearl lacquer, imitation gold tracing lacquer, etc.
Among them, imitation vermilion paint, imitation carving paint, imitation black paint, etc. are the most common.
The imitation vermillion lacquer style is often seen in chrysanthemum-shaped bowls or chrysanthemum-shaped dishes.
Its shape and glaze color are almost indistinguishable from lacquerware of the same period, which shows the superb craftsmanship.
Porcelain with imitation carved lacquer is also called "imitation red glaze".
Common utensil shapes include tureens, saucers, plates, goblets, candlesticks, pen holders, snuff bottles, etc.
This kind of imitation lacquer work can almost look like the real thing with the red lacquerware of the same period.
The inscriptions on the imitation lacquered objects are mostly signed with the six-character seal script inscription "Made in the Qianlong Year of the Qing Dynasty" in gold.
The imitation black lacquer utensils are mainly imitation black lacquer, which is very distinctive.
There is also imitation wood glaze, which is a new type of low-temperature glaze created during the Yongzheng period of the Qing Dynasty.
Imitation wood glaze is mainly imitated according to the texture, growth rings, color, defects and other aspects of real wood to achieve an artistic effect that is very similar to real wood.
If you just look at it briefly, you may think that the imitation work is made of real wood.
During the Qianlong period, this kind of highly difficult imitation wood-glazed porcelain was still produced.
Moreover, the varieties are more abundant than during the Yongzheng period, and they are often combined with pastel or other colored glazes on the same vessel.
The imitation wood-glazed porcelain of the Yongzheng and Qianlong periods were generally in the form of flower pots, arm rests, bowls, pen holders, etc.
There are even imitation wood-glazed gold-colored wares. The production process is exquisite and meticulous, which can be called a masterpiece of porcelain.
Similar to the imitation wood glaze, there is the imitation bamboo glaze. This type of porcelain is a low-temperature glaze porcelain fired from the Qianlong period to the late Qing Dynasty.
Imitation bamboo glaze porcelain mainly imitates the texture of bamboo, and the shape of the utensils is more common with pen holders.
Several other types of imitation glaze include imitation metal glaze. This type of porcelain is mainly made to imitate gold, silver, bronze, etc.
These imitation metal glazed porcelain are almost the same as real gold, silver and bronze wares.
Since there are glazes that imitate metal, there are also glazes that imitate silk fabrics.
Silk-like glazes are mostly imitated from ancient tapestry.
Since Kesi is one of the silk fabrics used by the royal family in ancient my country, its nobility can be seen.
Finally, there is imitation gemstone glaze, which should be the most expensive porcelain.
Imitation gem glazes are mainly imitation ruby glaze, imitation sapphire glaze, imitation turquoise glaze, etc.
Among them, the imitation ruby glaze and the imitation sapphire glaze were fired by the official kilns during the Qianlong period and Jiaqing period of the Qing Dynasty. They are a kind of low-temperature glazed porcelain.
