Chapter 1,256 Royal Use
It is difficult for the wood kiln to control the temperature, which causes the problem of too high and too low temperatures.
This will not control the firing temperature well, and will naturally cause losses.
The yellow-glazed porcelain among them is even more difficult to grasp.
So after leaving the kiln, let alone the kiln treasure (the best-made one made in a kiln), even if it is more qualified, it can surprise people.
As for how to identify and pass the firing, the method is also very simple. The easiest thing is to listen to the sound.
Youpin's sound is crisp and loud, and after the cup body and lid collide, echoes linger.
The inferior product's voice is heavy and dull, and the echoes are not crisp.
The second is to look at the luster. The color of the best products is like jade, while the color of the inferior products is gray and dark.
The other is light transmittance, the high-quality product has strong light transmittance and good glossiness.
Under the light, golden light shines like an emperor's yellow robe.
The inferior products have extremely poor light transmittance or even light-transmitting.
In addition to the hard features of sound, luster, jade quality, and light transmission, they are also thickness and weight.
Because the high-quality products are made of good body clay, the porcelain is very light and thin, as soft as jade, while the inferior products are thick and heavy.
Finally, let’s see whether the craftsmanship is exquisite or not, you can see it in the details.
In terms of yellow glaze operation, in certain parts of the product, such as the bottom and mouth of the cup, the yellow glaze process is very fine, while the inferior products are not detailed.
Among the royal porcelains, the more special ones are the delicate yellow glaze, lemon yellow glaze and tea powder glaze.
These glaze colors are the best among yellow glaze porcelain.
These unique yellow-glazed porcelains all have their own artistic charm and contemporary style.
You should know that these glaze colors are generally royal monopoly varieties, and most people don’t know how to make them because they dare not make them.
Especially during the Ming and Qing dynasties, the imperial power was still very heavy.
Most of the yellow-glazed porcelains from these two periods were fired in official kilns.
Because the characters "Huang" and "Huang" are homophones, most of the porcelains fired are monopolized by the royal family and become special porcelains for the royal family. However, the folk kilns do not allow the firing of yellow-glazed porcelains.
Anything like this, as long as it involves monopoly, will generally have problems.
Therefore, the yellow-glazed porcelain of the Ming Dynasty is particularly worth mentioning, but the folk things are not worth mentioning!
In the Ming Dynasty, especially when several emperors were in power and peace, all kinds of porcelain were fired very well.
Because only when the country is at its peak, there will be money to invest in side jobs and can do well.
For example, sweet yellow glaze, this is a low-temperature yellow glaze. Its glaze color is pure, delicate and elegant, and the glaze surface is bright and pleasing to the eye.
Because it is made by glaze pouring, it is also known as "glaze pouring yellow glaze".
This beautiful porcelain was first burned during the Xuande period of the Ming Dynasty.
Most of the yellow glazes at this time had orange peel patterns, which can be said to be the distinctive feature of Xuande yellow glaze porcelain.
Xuande yellow glaze is rare, so it is extremely precious.
The Hongzhi yellow glaze in the Ming Dynasty was a kind of yellow porcelain made during the Hongzhi period of the Ming Dynasty, such as chicken oil yellow.
This kind of porcelain is finer and smoother than Xuande yellow glaze, and has a delicate beauty. The production process is very exquisite and is well-known to future generations.
The Zhengde yellow glaze in the Ming Dynasty inherited the tradition of the Hongzhi period, but the glaze color was more serious and the fineness was far less than that of the objects in the Hongzhi period.
During the Jiajing period of the Ming Dynasty, many people liked to combine yellow glaze with other paintings, which reflected their outstanding artistic charm.
The yellow glaze of the Wanli period of the Ming Dynasty no longer has the delicate yellow color, and the glaze color mostly reflects the deep beauty.
The end of the Ming Dynasty, and the next is the Qing Dynasty.
This kind of yellow glaze was also imitated in the Qing Dynasty, but the imitation effect was still different from that of Hongzhi yellow glaze.
For example, during the Kangxi period, we focused on imitating the style of the Hongzhi period.
During the Yongzheng and Qianlong periods, we tried to combine imitation yellow glaze with other paintings.
During the Daoguang period, it was more inclined to imitate some yellow-glazed study instruments.
Among yellow-glaze porcelain, the most precious one is delicate yellow glaze, followed by lemon yellow glaze.
Lemon yellow glaze is a kind of yellow glaze porcelain fired during the Yongzheng period of the Qing Dynasty. Its fire is based on the delicate yellow glaze of the Ming Dynasty.
The glaze color of this yellow-glazed porcelain is elegant and pleasant, with no obvious color difference, and the glaze layer is very uniform.
In terms of shape, it mainly focuses on various exquisite small objects.
For example, common ones include bowls, plates, cups, bottles, plates, etc., which reflect a dignified and elegant artistic style.
Finally, there is the tea powder glaze known as the royal yellow glaze porcelain, which is a high-temperature yellow glaze.
The glaze color is like the fine powder of tea leaves, with yellow and small spots.
This glaze color has a very good final effect, usually simple and elegant, with extraordinary meaning.
Of course, the characteristics are also very obvious.
Tea powder glaze, generally most of the glaze surfaces are opaque.
This is due to the different firing atmosphere, the glaze color shows a diverse feature.
For example, common ones include eel yellow, crab armor green, snake skin green, old monk's clothes, etc.
These glaze colors are worth mentioning because they are all characteristics of the times.
For example, eel yellow, a variety of crystal glaze.
Because the glaze contains iron, magnesium and silicic acid, crystals precipitate when firing through a high-temperature oxidation flame.
This glaze is yellow and moist, with black or yellow-brown spots, just like the skin color of eels, hence the name.
There is a point here. If you want to fire eel yellow, the selected glaze must contain iron, magnesium and silicic acid, and then fire at high temperature to obtain it.
It is simple to say here, but when you want to get the desired result, you must have a deep study of the glaze.
In ancient times, these crafts generally existed in the form of secret recipes and secret techniques.
And now, after studying and understanding the principle of firing, it can be 100% firing.
Also, a kind of glaze often forms various glaze colors due to the different firing temperatures, and the same is true here.
Let’s talk about Crab Armor Green, it is one of the crystalline glaze varieties fired in the official kiln of the Yongzheng Dynasty of the Qing Dynasty.
It evolved from tea powder glaze, with a little yellow in dark green or a little green in yellow in yellow, and is called "crab armor green" or "crab shell green".
The glaze application method is to hang green glaze, which is fired by high-temperature reduction flame in the kiln.
Due to different temperatures, the color can be changed, such as crab armor green, eel yellow, snake skin green, etc., which are all the same glaze and are formed at different temperatures.
Therefore, the same glaze presents these three colors because of different temperatures.
In addition to crab armor green and eel yellow, and snake skin green, this glaze color is well made and is also very beautiful.
One of the snake skin green works that exist now is very exquisite, which is a snake skin green glaze jade pot spring from the Qianlong period of the Qing Dynasty.
The size is 30.3cm high, which is the standard shape of the official kiln in the Qianlong period, with a wide mouth, a tied neck, oblique shoulders, a bulging belly, and a ring foot.
The tire is hard and delicate, the tire is neat and the lines are smooth and beautiful.
Apply white glaze in the bottle, as white as condensed fat.
The whole body of the bottle is covered with snakeskin glaze, and the green is a bit deep, but it looks very comfortable and does not feel any dark.
