Guanyin soil

It is a kind of white soil.

Some people ate it during the famine.

That kind of soil cannot be digested by the human body.

So you won’t be hungry.

Because it cannot be absorbed, there is no nutrition.

Guanyin clay is also called kaolin clay

China is the hometown of porcelain and the hometown of "Kaolin". "Tiangong Kaiwu·Tao Ju Chapter" said: "Two mountains of Wuyuan and Qimen have soil: one is Gaoliang Mountain, which produces japonica rice soil, which is hard in nature; the other is Kaihua Mountain, which produces glutinous rice soil. Its nature is soft. Two When the soil is combined, the porcelain is ready.” The so-called glutinous rice soil refers to kaolin. Kaolin is an important raw material for the body and glaze of ceramic products and clay refractory materials. It is the porcelain raw material first discovered and used by ancient porcelain workers in Jingdezhen, the porcelain capital of my country. It is named after its origin was first discovered in Gaoling Village, 45 kilometers east of Jingdezhen, Jiangxi. It has now become a common term for porcelain raw materials around the world. In other words, "kaolin" has become the unified name for similar clays in the world. This is a great contribution of our country's porcelain workers to the world.

The development and utilization of kaolin laid a solid foundation for the rapid development of Jingdezhen's porcelain industry and played a major transformative role in the development of world ceramic technology. From the Yuan Dynasty to the mid-Qing Dynasty, kaolin mining was booming. Although Kaolin Mountain no longer produces kaolin today, due to its position in the history of ceramics and its large number of ancient relics, it has become a tourist attraction in Jingdezhen, the porcelain capital. It integrates its cultural characteristics and natural scenery, becoming a ceramic monument with extremely rich natural and cultural landscapes. What remains today are the mounds of snow-white tailings piles, the ancient streets of Dongfu Village, the ancient wharf, the Ming Dynasty stone tablets, the Qing Dynasty shops in Gaoling Village, the ancient mines, Shuikou Pavilion and the related mining of kaolin from the Wanli period of the Ming Dynasty to the Yongzheng period of the Qing Dynasty. inscriptions, etc. People are not only investigating the mining and washing of porcelain clay in ancient times, but they can also appreciate the wonder of the snow-white tailings against the green mountains and recall the prosperity of porcelain making and transportation at that time.

The main characteristics of the chemical composition of kaolin are high aluminum content and low flux content. Its production areas are all over the country, with native kaolin clay in the south and clay kaolin clay in the north.

With the initial single-material porcelain (using porcelain stone as a raw material to make porcelain) to the later binary formula (using porcelain stone and kaolin as two raw materials to make porcelain), my country's porcelain making technology has also evolved. Getting better and better day by day. Using kaolin as a raw material for making porcelain has greatly improved the level of ceramic technology and product quality, and promoted the development of ceramics.

The origin of kaolin clay is quite fascinating. Legend has it that there was a couple surnamed Gao who were poor but extremely kind-hearted in Gaoling Village. One winter, when the north wind was howling and the dripping water turned into ice, a white-haired old man in shabby clothes fainted on the eaves of the Gao family. After the Gao couple found out, they killed him. He helped him into the house to warm him up and made him porridge to drink... Before the old man left, he directed the Gao family and his wife to go to the top of Gaoling Mountain and dig ninety-nine and eighty-one times without stopping, and there would be a miracle. What happened...According to what the old man said, the Gao couple discovered "white glutinous rice flour" under their hoes, and used the knowledge they received to go up the mountain with the villagers of Gaoling Village to collect mud, make blanks, and bake porcelain. The porcelain made is strong, white, shiny and lovely.

Since Jingdezhen used kaolin to prepare porcelain, the porcelain produced in Jingdezhen is whiter, flawless and more exquisite. In 1712, the French missionary Entrecola introduced the porcelain clay of Kaolin to foreign countries. Since then, Kaolin clay has become famous and worth hundreds of times.
