Yuhua Stone Knowledge - Yuhua Stone Definition
Son: You must be famous first! If you don't understand the concept of the stone, you can't understand the source of the stone and its culture thoroughly, and you can't appreciate it.
Mr. Liu Shui wrote in his "Yu Hua Shi Appreciation" -----
Regarding the definition of Yuhua Stone, there are currently several viewpoints:
First, it is believed that only the agate gravel with ornamental value is called the rain stone, which is called "rain flower agate". The agate stone produced in other places is also called "rain stone". Other gravel is not called rain stone.
Second, it is believed that all gravel produced in Nanjing's “Yuhuatai Gravel Layerâ€, whether or not it has ornamental value, is collectively referred to as “Yuhua Stoneâ€, which is the “abbreviation†of “Yuhuatai Gravel Layer†gravel.
Thirdly, it is believed that only the gravel with ornamental value produced in the “Yuhuatai Gravel Layer†in Nanjing is called Yuhuashi.
Mr. Liu Shui believes that the first view is too narrow and the geographical attributes are vague. The second view is too broad and does not consider the ornamental attributes and aesthetic values. In view of the natural attributes, aesthetic values, and origin of the stone species. The human factor tends to a third perspective.
Mr. Chi Cheng opened the Ming Dynasty in his "Yuhua Stone Spectrum", expounding the broad and narrow sense of Yuhua Stone from the two aspects of the origin and texture of Yuhuashi---
The narrow sense of the texture----refers to the ovate agate, crystal, chalcedony, opal and various ornamental fossils.
The broadness of the texture----refers to the oval colored stone and the textured stone.
The narrow sense of the place of origin----specially pointed out the oval agate, crystal, chalcedony, opal and various ornamental fossils and texture stones produced in Nanjing Yuhuatai.
The generality of the place of origin refers to the oval agate, crystal, chalcedony, opal and various ornamental fossils and textures produced by Yuhuatai and other areas outside Yuhuatai, such as Liuhe, Yizheng, Jiangning, Jiangpu, and Hexian. The stone is exactly the same stone.
The generalized area of ​​the place of origin refers to the stone that is produced by Yuhuatai, except for Yuhuatai and beyond the surrounding areas of Nanjing. It is produced in the same way as the Yuhuatai oval agate, crystal, chalcedony, opal and various ornamental fossils and texture stones.
Nowadays, the broad one has been recognized by the majority of Yuhua stone lovers. People have classified Liuhe's "Ling Rock", Yizheng's "Jiangshizi" and Jiangning's "Snail Stone" into one category. The colored pebbles like the pebbles that are produced outside the region and produced in other parts of the Yangtze River Basin are not fully recognized because they are poorly understood. In fact, it is completely the same in terms of texture. The meaning of generalized two is recognized by people, but it is only a matter of time.
I personally prefer the narrow point of view. The reason is that the Yuhua stone with aesthetic value is now very small. The Yuhuatai area in Nanjing is almost non-decent. It is mainly produced in Liuhe and Yizheng, and it is no more than 70 kilometers away from Nanjing. If the stone in the Yuhuatai area is orthodox, it is actually the price. Therefore, I think that the natural stone that has the texture, the bright color and the crystal clear and transparent texture of the agate, crystal, chalcedony and opal produced in Liuhe and Yizheng areas around Nanjing can be called “rain flower stoneâ€. . In the local area, this kind of stone is often called “living stoneâ€. Mr. Liu Shui classifies it as “fine stoneâ€. Mr. Chi Cheng also mentioned the commonly known “live stone†in his book. This is used as a reference for reference. If the same area is produced, it should be classified as Yuhuashi. I do not agree to attribute a very small number of fossils with ornamental value to the category of Yuhuashi. Their research value is greater than their ornamental value. As for the paving rain and pebbles used for building materials, they are called local "garden stone" and "special stone".
The words of a family are for reference only.
