My system is not decent

Jiajing blue-glazed porcelain is more popular, one is the rich and colorful shapes, and the other is the new development of glaze colors.

In addition to traditional palace sacrificial vessels and display porcelain, blue glaze products are also common in daily-use vessels.

In addition to Jilan glaze color, a new "huiqing" glaze was created.

The glaze color of Jiajing blue glaze is slightly purple in blue, some glazes have fine grains, and some have brown spots, and a layer of caramel glaze is applied on the ring feet.

Jiajing Huiqing glaze is often engraved with dark inscriptions, all of which are in six-character regular script.

The shapes include pots, washers, bowls, plates, cups, slag buckets, incense shovels, etc.

Some are still shallowly carved with dragon and phoenix, cloud dragon and twining patterns.

These utensils are mainly hidden in the Palace Museum in Wanwan and Shendu, all of which are old collections in the palace.

These blue-glazed porcelains of the Ming Dynasty are considered national treasures, and each piece is very precious.

Therefore, such porcelain, naturally some people want to imitate it.

The focus of imitation has two aspects, one is the bottom line.

The base model is the key point of imitation, because it is difficult to imitate, so there will be methods such as changing the old base and taking over the old base.

For example, the base model of Ming Dynasty blue glazed porcelain is not easy to imitate.

There are two types of blue and white and dark engravings, and many of them are "Daming Xuande Annual System" double-line six-character regular script.

Like other porcelains of the Ming Dynasty, all four-character inscriptions are also imitations.

In addition to common shapes such as bowls and plates, there are also shapes such as pots, vats, statues, basins, mitral pots, and lotus petal pots.

In addition, a new variety of sprinkled blue glaze appeared in the Xuande period.

Because of its blue glaze, white spots are naturally distributed, like snowflakes falling, so it is also called snowflake blue.

Sprinkling blue glazed porcelain is also a lime alkali glaze with cobalt as the coloring agent, but the glazing process is slightly different from Ji blue glazed porcelain.

Xuande sprinkled blue-glazed porcelain is very rare.

With such a rare treasure, there will naturally be many legendary stories.

For example, there is a piece of blue glaze from the "royal plaything" to the floating folks, which is widely circulated in the industry.

In the 70s, a mysterious old lady came to the Shendu Cultural Relics Store with a rag bag on her back.

I found the staff, took out a porcelain bowl from the cloth bag, and said that I would sell it for some money.

According to the old lady, this bowl has been stored in her home for many years, filled with salt, and later used to feed chickens, so it must be old.

But I don't know which dynasty it is from, and the surface color is uneven, so I don't know how much it can be exchanged for.

This bowl is quite peculiar, one is large, with a diameter of 25.3 cm;

The second is that the shape of the bowl is special, the body is thicker than ordinary bowls, about 1 cm, and it has a flat bottom, so it should be called bowl;

The third is that the blue color in the glaze is uneven.

The inside of the bowl is covered with white glaze and the outside with blue glaze, and the inner bottom is very dirty.

At that time, there was no research on the blue glaze sprinkled in Xuande, but in the "Notes of Nanyao" in the Yongzheng period, the blue glaze sprinkled was called "blowing green", and it was believed to be a new system in the early Qing Dynasty.

Therefore, the cultural relic store regarded it as Qianlong's porcelain and bought the old lady's bowl for 80 yuan.

The money was considered a considerable sum at the time, and the old lady took the money and left happily.

This is very similar to what happened to the blue-glazed plum vase with cloud and dragon patterns.

It's just that the price of this one is a bit higher, reaching 80 yuan, which is four or five times higher than eighteen.

I don't know if it is the owner of the treasure, lucky or unlucky.

After receiving this bowl, the staff at that time put the bowl in water to clean it.

When the dirt on the bottom of the bowl was washed away, the six characters "Daming Xuande Year System" were revealed.

From the shape, material to craftsmanship, the experts agreed that this is a piece of porcelain fired in Jingzhen during the Xuande period of the Ming Dynasty.

And its most precious place, unexpectedly, was mistaken by the old lady for a defect.

This defect is a unique process of this porcelain called blue glaze.

The origin of the sprinkled blue glaze is also very clear.

"Sprinkling blue glaze" was first created in Jingzhen, Xuande, Ming Dynasty.

Because the glaze surface looks like falling blue water droplets, it is called "sprinkling blue";

It is also called "snowflake blue" because of the white glazed spots like snowflakes floating on the blue water.

Regarding the birth of the blue glaze, it is actually related to a "willful" imperial decree of Emperor Xuande.

Emperor Xuande, namely Zhu Zhanji, was the fifth emperor of the Ming Dynasty.

The emperor couldn't resist having fun while he was busy with government affairs.

He is very fond of cricket fighting, and every year local officials pay tribute to top-quality crickets for him to play with.

Therefore, Jingzhen Royal Kiln Factory fired a large number of cricket jars.

In addition to raising birds and amusing insects, Emperor Xuande was also fascinated by the game of throwing dice.

It is this hobby that has created the porcelain variety of sprinkled blue glaze.

In order to meet the needs of this game, Emperor Xuande ordered Jingzhen Imperial Kiln Factory to fire a kind of porcelain specially used for playing dice for him, and the glaze color should be unprecedented and unprecedented.

The imperial kiln factory did not dare to neglect after receiving the imperial edict, and immediately gathered the best porcelain craftsmen and the best materials at that time to start production.

After painstaking research and development, the blue-and-white glazed porcelain—the blue-and-white cloud-dragon-patterned cricket pot was finally fired.

So, how is the sprinkle blue glaze fired?

Sprinkling blue glaze is not simply dipped in glaze, but blown on with a tube.

On the fired white-glazed ware, the bamboo tube is dipped in the blue glaze juice and blown on the surface of the ware.

In this way, spots with uneven thickness and different depths will be formed, and then a thin layer of glaze will be fired at high temperature.

The rest of the white glaze is like falling snowflakes, hidden in the blue glaze.

Generally speaking, due to the different degree of fine workmanship, the effect of the formed porcelain is also different.

If the glaze is blown all over the utensils, the blowing is uneven, and the depth is different, it is snow-covered blue.

If it is evenly and densely distributed on the porcelain cup to form dots, it is the real blue glaze.

"Tao Ye Tu Shuo" records: "The diameter of the bamboo tube is over an inch, and the length is seven inches. The mouth is covered with spun yarn, dipped in glaze and blown. Blow several times, depending on the size of the billet and the type of glaze, as many as seventeen or eight times, as few as three times. Four times."

It can be seen from the records that the firing process of sprinkled blue glaze is very complicated and the success rate is relatively low.

Therefore, blue-glazed porcelain was a relatively rare variety at that time.

There are only a few pieces of blue-glazed porcelain from the Ming Dynasty in my country, so they are very precious.

In the first month of 1435, Emperor Xuande contracted an unknown disease and died soon after.

After Xuanzong's death, the game of dice fell out of fashion.

Later emperors also ordered the firing of blue-glazed porcelain, but due to the complicated process of spraying blue-glazed porcelain, the success rate was extremely low, and a lot of manpower and material resources were required, and the cost was too high.

So after the death of Emperor Xuande, the blue glaze was sprinkled and stopped burning.

It is such a rare treasure of the palace, which mysteriously disappeared from the palace in just ten years from birth to cessation of burning.

Such a good thing as blue-glazed porcelain can't be lost.

It was not until the Kangxi period of the Qing Dynasty that production resumed again.

Blue-glazed porcelain from the Kangxi, Yongzheng, and Qianlong periods of the Qing Dynasty has stable color and fine workmanship. Many are decorated with golden colors, and a small amount are supplemented with multicolored and underglaze red decorations.

Due to the complicated firing process and low success rate, blue-glazed porcelain was a relatively rare variety at that time.
