What is red porcelain made of, and why is red porcelain in the glaze precious?

Questioner: Hello, these netizens are not correct, you are asking "what is red porcelain made of" Now I will ask you this question.

Red porcelain, also known as "Chinese red porcelain", the world's earliest red porcelain fired is the copper red glaze pot fired by the Tongguan Changsha kiln in the late Tang Dynasty of China (1100 years ago), it uses copper oxide as a colorant, adds it to the glaze, and fires it at a high temperature of more than 1200 and reducing atmosphere by glazing on the surface of the pot. The successful firing of copper red glaze in Tongguan Changsha kiln has created a precedent for red porcelain in the world. It was not until the founding of the People's Republic of China in 1949 that the long-turbulent society was stabilized and developed, and the ceramic industry was reborn.

Especially in the 90s of the 20th century, taking advantage of the wind of reform and opening up, China's ceramic industry has entered a new period of comprehensive prosperity and development, during which many new processes, new technologies and new products have appeared. After 20 years of careful research, Mr. Yin Yanzheng, the inventor of Chinese red porcelain, the chairman and general manager of Changsha Dahong Ceramics Development Co., Ltd., has developed a series of red porcelain products with unique glaze-making technology and firing process, and won the national invention patent. This series of products are fired at a high temperature of more than 1200 meters, with bright colors and uniform color, and their hue and main indicators are at the international leading level of similar products.

This kind of red porcelain is named "Chinese red porcelain", its hue is different from the traditional copper red, iron red and gold red, and is red, is the Chinese nation's favorite and the national flag, the national emblem color consistent with the red, it symbolizes the prosperity of the Chinese nation, symbolizes the prosperity of the country, symbolizes the prosperity of the country and the strength of the people.

The bright red color is due to the coloration of the encapsulated selenium-cadmium red material in the silicate melt. Generally, it is decomposed when it is burned to more than 800, and only by using a special process to improve its high temperature stability by wrapping, the higher the temperature, the greater the difficulty of the preparation process. Now there are 1450 red porcelain on the red porcelain market, many consumers have been deceived, in fact, the 1450 red porcelain is low-temperature red porcelain, are low-temperature firing, after plain firing, glaze firing, red burning, gold firing four times accumulated temperature, such as plain firing is 200, glaze firing is 800, red firing is 300, gold firing is 150, in the sum of their temperatures is 1450.

Such porcelain is easy to fade and fade gold. Because the porcelain surface and the glaze are not fused together at high temperatures, this is the so-called low-temperature red porcelain, but because the sales of low-temperature red porcelain are low, good unscrupulous traders are used to do high-temperature red porcelain sales, hoping to sell them at a good price. The real high-temperature red porcelain is fired at five high temperatures, the first is 500 embryo voxel firing, the second is 1300 white glaze firing, the third is 1200 red glaze firing, the fourth is 800 color firing, and the fifth is 1250 finished firing.

If we follow the low temperature accumulation method, this porcelain will reach 5050. Consumers, wake up, don't be deceived by low-temperature red porcelain like me.

Red porcelain does just that.

I hope you are satisfied.

Red porcelain originated from Hunan Liling noble, atmospheric, festive, auspicious, integrating traditional craftsmanship and modern science and technology, in the export market, gift market, festival market to maintain a good sales, and rapid growth.

Introduction to the characteristics of red porcelain.

Difficult: The process is difficult.

First, China's red firing is very difficult, the process is complex, usually four times into the furnace: one is plain firing; the second is glaze burning; the third is braised braised Fourth, gold burning. Each link cannot be deviated.

Under normal circumstances, Chinese red porcelain can only produce a finished product in the firing of many pieces, and the pass rate of large-scale finished products is even lower, the so-called "ten kilns and nine failures". The almost harsh manufacturing process and extremely low yield rate highlight the scarcity and preciousness of Chinese red porcelain.

Second, the formation of red porcelain is difficult. Copper red has to be decomposed at 800, and Chinese red has to be porcelain at a high temperature of 1450, which is the most difficult of the difficulties.

Expensive: The material is expensive.

The red glaze is now fired with the rare metal tantalum, which is a rare metal that is more expensive than **, and the golden pattern on the red porcelain is baked with pure gold with a purity of more than 99%, so it can be said that Chinese red porcelain is fired with **. Chinese red porcelain embodies the taste and practical value of noble art treasures from the aspect of materials.

Good: Ceramics are good.

Ceramics are usually divided into advantages and disadvantages by the firing temperature.

Low temperature pottery weight. Medium-temperature fine pottery.

Medium-high temperature white porcelain, strengthened porcelain.

High temperature fine white porcelain, jade porcelain light.

Chinese red porcelain is fired at a high temperature of 1450 degrees, and the jade is like clotted fat, which is precious.

Simple and elegant, delicate and white, thin as paper, and striking. Since its birth, red porcelain with its "thin as paper, transparent as a mirror, sound like chime, white as jade", porcelain delicate and transparent, beautiful and elegant shape, color surface moist and bright, flower surface colorful characteristics, the achievement of its white texture and luxurious shape, both use and art of the dual value, is a collection and gift of treasures.

Because red porcelain in the glaze is scarce, rare is expensive. Glaze red is a new variety of porcelain that appeared in the Yuan Dynasty, the principle is to use red copper material to paint and decorate the porcelain on the porcelain fetus, and decorate with transparent glaze, after high-temperature reducing flame atmosphere firing, the glaze will show a red pattern. The finished glaze red porcelain gives a very stunning feeling.

Blue and white glaze redBlue and white glaze red is one of the varieties of porcelain underglaze, blue and white is a kind of high-temperature underglaze color decoration, with metal cobalt as the colorant, the transparent glaze is fired at high temperature to show a beautiful blue.

The glaze red is also a kind of high-temperature underglaze color decoration, with metal copper as the coloring agent, and the decoration and firing process is the same as that of blue and white. This kind of decoration method of applying blue and white and red in the glaze to the same vessel is called blue and white glaze red.

The red porcelain in the glaze was created and fired in the Jingdezhen kiln of the Yuan Dynasty. It is an underglaze colored porcelain made of copper oxide as a colorant, painted directly on the tire with colored materials, covered with transparent glaze, and fired in a kiln fire of 1280 degrees Celsius to 1300 degrees Celsius. The color of copper oxide is difficult to control, and the temperature of the kiln room is high.

When the temperature is low, the color of the pattern will turn black; When the temperature is high, the pattern is easy to blur.

Introduction

China is the homeland of porcelain, and porcelain is an important creation of Chinese working people. The invention of porcelain is the great contribution of the Chinese nation to world civilization, and in English, "porcelain (China)" is the same word as China (China). Around the middle of the Shang Dynasty in the 16th century BC, early porcelain appeared in China.

Because it is still rough on the carcass and in the firing process of the glaze layer, the firing temperature is also low, showing primitiveness and transitionality, so it is generally called "primitive porcelain".

Chinese porcelain evolved from pottery, and the original porcelain originated more than 3,000 years ago. By the time of the Song Dynasty, the famous porcelain kilns had spread throughout most of China, and it was the most prosperous period of the porcelain industry. At that time, Ru kiln, Guan kiln, Ge kiln, Jun kiln and Ding kiln were called the five famous kilns of the Song Dynasty, and the more famous firewood kiln and Jian kiln were at that time.

The blue and white porcelain produced in Jingdezhen, Jiangxi, known as the porcelain capital, in the Yuan Dynasty has become a representative of porcelain.

Mr. Ye, a reader, wrote in the letter: "My ancestors left a red glaze vase, which is basically the same as the 'Qianlong Red Glaze Appreciation Vase' provided by Mr. Liang Guoxi in "Guangzhou**" on April 18, 2007, with a diameter and a height of 34cm, (the foot height is 2cm more than Liang Guoxi's bottle, and the glaze color is the same), with a seat. Now I would like to ask experts to identify it, whether it is a Qianlong vase.

Teacher Ye Jieyu identified the ** provided by the reader, saying that the red glaze vase was a Lang red glaze high foot appreciation bottle in the Guangxu period of the Qing Dynasty, and commented: The vase is simple and smooth, the red glaze color is bright and luxurious, the glazed glass texture is strong, and the glaze gradually deepens from the mouth to the bottom of the bottle, which is the result of the glaze flow in the firing process.

Lang red glazed porcelain is a kind of precious porcelain created and burned by imitating the red glaze of Ming Yongxuan when Lang Tingji, the governor of Jiangxi during the Kangxi period of the Qing Dynasty, was in charge of the imperial kiln in Jingdezhen, and the fine lines were opened inside and out.

Today, the real Kangxi period of Lang red glazed porcelain has been less in the world, but because the glaze color is red and scorching, the treasure is dazzling, like a ruby by the world's love, so in the late Qing Dynasty there were some imitation firing products, but due to the difficulty of the glaze production and the level of porcelain-making technology in the late Qing Dynasty, therefore, the Lang red porcelain in the late Qing Dynasty is far from the Kangxi period. However, the red glaze of the vessel is mostly gorgeous and even, the glaze layer is smooth and translucent, and the shape is regular and special, it is the best work in the late Qing Dynasty, and Ye Jieyu teacher estimated it at about 80,000 yuan.

I'm sure you should be able to learn something from this article.

Glaze red refers to the porcelain with copper red material painted on the tire, covered with transparent glaze, fired in a high-temperature reducing flame atmosphere, so that the glaze presents a red pattern. Glaze red is a major invention of Jingdezhen workers in the Yuan Dynasty, it is roughly the same as the blue and white process, the same underglaze color.

Jingdezhen's main art ceramics, daily industrial ceramics are very backward, because art ceramics need the original production process, so that it is valuable, modern high-tech technology, mechanical automatic equipment production of daily ceramics and industrial ceramics, in Jingdezhen almost no market!
