My system is not decent

It is difficult to control the temperature of the firewood kiln itself, which causes the problem of excessive temperature and low temperature.

This cannot control the firing temperature very well, which will naturally cause losses.

Among them, yellow glazed porcelain is even more difficult to grasp.

Therefore, after leaving the kiln, not to mention the kiln treasure (a small best product fired in one kiln), even if it is more qualified, it can surprise people.

As for how to judge whether the firing is qualified, the method is also very simple, the simplest is to listen to the sound.

The sound of Youpin is crisp and loud. After the cup body and cup lid collide, the echo lingers endlessly.

The sound of inferior products is heavy and dull, and the echo is not clear.

The second is to look at the luster. The color of high-quality products is like jade, while the color of inferior products is gray and dark.

Then there is light transmission, Youpin has strong light transmission and good gloss.

Under the illumination of the light, like the emperor's yellow robe, it reveals a golden light.

Inferior products have extremely poor light transmission or even opacity.

In addition to the hard features of sound, luster, jade, and light transmission, there are also thickness and weight.

Due to the use of high-quality body mud, the high-quality porcelain is very light and thin, as soft as jade, while the inferior ones are thick and heavy.

Finally, look at the craftsmanship. Whether the craftsmanship is exquisite can be seen in the details.

In the operation of yellow glaze, in some parts of the product, such as the bottom of the cup and the mouth of the cup, the yellow glaze process is very fine, while the inferior products are not meticulous.

Among the royal porcelain, the more special ones are Jiaohuang glaze, lemon yellow glaze and tea powder glaze.

These kinds of glaze colors can be regarded as the best among yellow glazed porcelain.

These unique yellow-glazed porcelains all have their own artistic charm and style of the times.

You must know that these kinds of glaze colors are generally the varieties monopolized by the royal family, and ordinary people can't make them because they dare not do them.

Especially during the Ming and Qing Dynasties, imperial power was still very heavy.

The yellow-glazed porcelain of these two periods was mostly fired in official kilns.

Because the word "Huang" has the same pronunciation as the word "Huang", the fired porcelain is mostly monopolized by the royal family, and it has become the special porcelain for the royal family, while the firing of yellow glazed porcelain is not allowed in folk kilns.

This kind of thing, as long as it involves monopoly, there will generally be problems.

Therefore, the yellow-glazed porcelain of the Ming Dynasty is particularly worth mentioning, but such folk things are not worth mentioning!

In the Ming Dynasty, especially during the reign of several emperors of Guotai Min'an, all kinds of porcelain were fired very well.

Because only in the period when the national power is at its peak, there will be money to invest in sideline businesses, and they can do well.

For example, Jiaohuang glaze is a kind of low-temperature yellow glaze. Its glaze color is pure, delicate and elegant, and its glaze surface is relatively bright, which is pleasing to the eye.

Because it is made by pouring glaze, it also has the reputation of "pouring yellow glaze".

This beautiful porcelain was first fired in the Xuande period of the Ming Dynasty.

Most of the yellow glazes at this time have orange peel patterns, which can be said to be a distinctive feature of the age of Xuande yellow glazed porcelain.

Xuande yellow glaze handed down utensils are very rare, so they are extremely precious.

The Hongzhi Yellow Glaze of the Ming Dynasty is a kind of yellow porcelain made in the Hongzhi period of the Ming Dynasty, like chicken oil yellow.

This kind of porcelain is finer and smoother than Xuande yellow glaze, and has a delicate and beautiful beauty. The craftsmanship is very exquisite and is well known to later generations.

The Zhengde yellow glaze of the Ming Dynasty inherited the tradition of the Hongzhi period, but the glaze color is more heavy and the degree of fineness is far less than that of the Hongzhi period.

During the Jiajing period of the Ming Dynasty, many people liked to combine yellow glaze with other colored paintings, which reflected a good artistic charm.

The yellow glaze of the Wanli period in the Ming Dynasty has lost its delicate yellow color, and the glaze color mostly reflects the beauty of deepness.

The Ming Dynasty ended, followed by the Qing Dynasty.

The Qing Dynasty also began to imitate this kind of yellow glaze, but the effect of imitation is still somewhat different from that of Hongzhi yellow glaze.

For example, during the Kangxi period, it was more focused on imitating the style of the Hongzhi period.

During the Yongzheng and Qianlong periods, attempts were made to imitate the combination of yellow glaze and other colored paintings.

During the Daoguang period, it was more inclined to imitate some yellow glazed study utensils and so on.

Among the yellow glazed porcelain, the most precious is Jiaohuang glaze, followed by lemon yellow glaze.

Lemon yellow glaze is a kind of yellow glazed porcelain fired during the Yongzheng period of the Qing Dynasty. Its creation and firing is based on the delicate yellow glaze of the Ming Dynasty.

This kind of yellow-glazed porcelain has a light and pleasant glaze color, without obvious color difference, and the glaze layer is very uniform.

In terms of shape, it is mainly based on various exquisite small utensils.

For example, bowls, plates, cups, bottles, saucers, etc. are common, reflecting a dignified and elegant artistic style.

The last is the tea powder glaze, which is known as the royal yellow glaze porcelain, which is a high-temperature yellow glaze.

Its glaze color is like the fine powder of tea leaves, with yellowish green and small spots.

This kind of glaze color, the final effect is very good, generally simple and elegant, with extraordinary meaning.

Of course, the characteristics are also very obvious.

Tea powder glaze, generally the glaze surface is mostly opaque.

This is due to the different firing atmosphere, which makes the glaze color show a variety of characteristics.

For example, eel yellow, crab shell green, snake skin green, and old monk's clothing are common.

These kinds of glaze colors are worth mentioning, because they are the characteristics of the times.

For example, eel yellow, a variety of its crystal glaze.

Because the glaze contains iron, magnesium and silicic acid, crystals will precipitate out when fired in a high-temperature oxidizing flame.

This kind of glaze is yellow and moist, with black or yellowish brown spots, just like the skin color of eel, hence the name.

There is an important point here. If you want to fire eel yellow, the selected glaze must contain iron, magnesium and silicic acid, and then it can be obtained by firing at high temperature.

It is simple to say here, but when it is actually fired, if you want to get the desired result, you must have a deep research on the glaze.

In ancient times, these crafts generally existed in the form of secret recipes and secret techniques.

But now, after researching and understanding the principle of its firing, it can be fired 100%.

Also, often a kind of glaze will form various glaze colors due to different firing temperatures, and it is the same here.

Let's talk about crab armor green, which is one of the crystal glaze varieties fired in the official kiln of the Yongzheng Dynasty in the Qing Dynasty.

It is evolved from the glaze of tea powder. It is slightly yellow in dark green or green in yellow. It is called "crab shell green" or "crab shell green".

The glazing method is to hang the glaze on the green body, enter the kiln and fire it with a high-temperature reduction flame.

Changeable colors due to different temperatures, such as crab shell green, eel yellow, snake skin green, etc., are all formed by the same glaze at different temperatures.

Therefore, the same glaze exhibits these three colors because of the difference in temperature.

In addition to crab shell green and eel yellow, and snakeskin green, this glaze color is well made and very beautiful.

One of the surviving snakeskin green works is very exquisite. It is a snakeskin green glazed jade pot spring in the Qianlong period of the Qing Dynasty.

The size is 30.3cm high. It is the standard shape of the official kiln in the Qianlong period, with a wide mouth, a narrow neck, sloping shoulders, a bulging abdomen and a round foot.

The tire quality is hard and delicate, the tire repair is neat, and the lines are smooth and beautiful.

White glaze is applied inside the bottle, which is as white as curdled fat.

The whole body of the bottle is glazed with snakeskin, the green color is a bit dark, but it looks very comfortable, without any dark feeling.
