My system is not decent

It can be said that the success or failure of kiln transformation porcelain depends entirely on a fire.

The success of high-temperature kiln glaze transformation depends entirely on your skill and glazing skills, as well as the mastery of the glaze properties, as well as the thickness and sequence of glazing.

Chen Wenzhe has studied all kinds of technical difficulties clearly, but that's it, he needs to rely on luck to fire some special kiln-changing glazes.

Chen Wenzhe didn't want to touch the illusory existence of luck.

Therefore, he intends to make some things that can be mastered, such as Langyao red, Langyao green, apple green glaze, and apple green glaze.

These are also kiln-changed glazed porcelain, but he was able to obtain perfect works by controlling the firing technology.

If you want to successfully fire these two simplest kiln glazed porcelains, you must first fire cowpea red porcelain and Langyao red porcelain.

Cowpea red is a kind of copper red high-temperature glaze, which is a variety of copper red glaze that appeared in the late Kangxi period of Qing Dynasty.

It is named for its light and pleasant color tone, uneven pink color, like red cowpea, and light and beautiful shape.

And because of its bright red color, which looks like a child's face, and like peach blossoms in March, it is also called "baby face", "peach blossom slice" and "beauty drunk".

The enamel of cowpea red is very uniform and delicate, and contains powder.

The red glaze is often dotted with natural green moss spots formed due to the difference in oxidation and reduction during firing.

The glaze color can be divided into high and low, and the best one is called "Dahongpao" or "Zhenghong". The glaze color is bright and bright, the whole body is the same color, clean and flawless.

In the middle, the glaze is like cowpea skin, with spots of different shades, which is very soft and pleasing to the eye.

Some have "defective beauty" green moss spots on the body or mouth edge, which are called "beauty drunk" or "beauty Ji" today.

The lighter tone is called "baby face" or "peach blossom slice". Although it is not as beautiful as the darker tone, it has an elegant and delicate appearance.

Those of the lower grade are either lighter in tone, or dark and turbid, and are called "suckling mouse skin" or "elm bark".

As for the gray and black uneven "donkey liver, horse lung" color, and the lower part of the vessel with black glaze burnt bubbles, they are the most inferior products.

Cowpea red has no large items, and it is commonly used as stationery, such as Taibai Zun (water bowl), pomegranate Zun, chrysanthemum vase, willow-leaf vase, washing and printing boxes, etc.

These utensils are special, and they are more difficult to make than bowls and dishes. It turns out that Chen Wenzhe has never made a few of them.

Now doing it, he still feels very novel.

Especially pomegranate statues, chrysanthemum vases, and willow-leaf vases. These types of utensils are rare, and he has never made them.

This time, the speed is slower. From mud training to embryo drawing, after that it needs to be dried, and then the embryo needs to be dried again.

After a step-by-step process, only qualified embryos can be engraved, glazed, and fired.

Of course, if you want apple green, you must first burn cowpea red.

It is also very difficult to burn cowpea red.

In ancient times, it could only be produced in a small amount by official kilns, and it was only used by the royal court.

It's not that the ancients didn't want to burn more, but it's really difficult.

Cowpea red, which is difficult to burn once in a thousand years, is really not nonsense.

Even in Jingzhen, there is a local proverb in Jingzhen, "If you want to be poor, burn red", which means that high-temperature red glaze is difficult to burn, so hard that it can make you poor?

If you ask: What is the most difficult to burn in ceramics?Answer: high temperature red glaze porcelain.

my country's high-temperature "copper red" glazed porcelain appeared in the Tang and Song Dynasties.

Since the Yuan Dynasty, single-color pure red-glazed porcelain has been created and fired, and it has become a variety for court furnishings, viewing and playing at that time.

But the varieties fired at that time were all black, and the firing technology was not mature.

It was not until the Ming Dynasty that the firing was really successful. The "Ruby Red" of the Yongle Xuande Dynasty in the Ming Dynasty, the "Cowpea Red" and "Langyao Red" in the Kangxi Dynasty of the Qing Dynasty are brightly colored and unique, and are highly praised by people, among which Cowpea Red is the most expensive.

my country's first cowpea red was actually an unexpected failure.

Because the temperature of the kiln was not well controlled, the color of red cowpea appeared in the work.

But this unexpected work has an incomparable flawed beauty.

Red is lovely, red is mesmerizing, it has surpassed the beauty that words can express, and has become a rare and excellent work in the history of Chinese ceramics.

According to historical records, Emperor Kangxi, who loved monochrome glaze, loved cowpea red glaze very much.

However, with the level of science and technology 300 years ago, the law of copper ion reduction in the process of forming cowpea red glaze is not known.

Therefore, every firing must be done regardless of cost and price.

At that time, a lot of manpower, material resources, and financial resources were used, and precious raw materials such as rubies from the Western Regions, red coral, and agate were mixed into the glaze.

The firing rate is still very low, that is, individual variation is an accidental phenomenon of "unintentional insertion".

After Kangxi, the firing recipe was lost

The cowpea red that was re-fired in the Guangxu period has lost the style of the imperial kiln in the Kangxi period, and the carcass is relatively thicker.

After Guangxu, the formula was lost again.

Therefore, the number of cowpea red whole vessels handed down is very small, and it has always been the target of collectors.

Up to now, there is a saying among the people that "collect cowpea red, and you will never be poor for a lifetime".

At the beginning of the last century, most of the cowpea red porcelain was scattered abroad and collected in famous museums and collectors all over the world.

According to statistics, there are more than 100 pieces in the collection of the Metropolitan Museum of China alone, which is more than the sum of the collections of all museums in China, while the Capital Museum has only one complete piece.

Cowpea red is not a large piece of utensils handed down from generation to generation. It may be a porcelain craftsman in the Kangxi Dynasty. Considering that the cowpea red glaze matches the exquisite and small utensils, it can show its delicate beauty even more!

There are eight common shapes of utensils, Taibai Zun, Chrysanthemum Vase, Willow-leaf Vase, Raisin Zun, Convex Pan Chi Vase, Ink Clay Box, Boring Gong Washer, Apple Zun, generally no more than 24 cm high.

During the Kangxi period, Jihong glaze, cowpea red glaze and Lang kiln red glaze porcelain fired by JDZ kiln are like three wonderful flowers among high-temperature copper red glaze porcelain.

If Langyao red-glazed porcelain brings people a dazzling glaze color, and Ji red-glazed porcelain brings people a deep and stable aesthetic feeling, then cowpea red-glazed porcelain is fascinating with its graceful and magical colors. It is pleasing to the eye.

For the first imitation of this kind of top porcelain, Chen Wenzhe must imitate all the types. Fortunately, there are only eight classic types of porcelain, so it is not too troublesome to make.

As for whether it will be successful after being fired, in fact, compared with the ancients, Chen Wenzhe's advantage is too great.

Copper control, that is, the use of an appropriate amount of copper element, can get the perfect cowpea red porcelain.

The ancients did not understand this point, but Chen Wenzhe understood it too well.

He has fired too many copper-red glazed porcelains, and even the more difficult-to-control blue-and-white underglaze red, he can successfully fire, not to mention the single-color glazed copper-red glaze.

Even so, Chen Wenzhe only started to imitate some high-quality goods after he made a batch of simple-shaped cowpea red porcelain and tried it successfully.

This is something that can't be helped, after all, the raw materials used in ancient and modern times are different, so Chen Wenzhe must be careful.

In this way, if there is a problem with the raw materials and the firing fails, he will not waste much effort.
