Why can DuanYan become the first of the four famous inkstones?

I think the inkstone can become the first of the four famous inkstones because of the long history of the inkstone, the material is special, the stone is moist and delicate, does not damage the brush, does not freeze in winter, does not deteriorate in the summer, can enhance the stability of the ink and so on the advantages, so that it can stand out from the four famous inkstones of the first. Next, from several aspects of the advantages of the inkstone:

The first aspect, with a cultural background, a long history. Duan inkstone first began to appear from the Tang Dynasty, when it is still practical, mainly for ink research. And the Song Dynasty inkstone began to appear some carving design, more sophisticated. And the Ming Dynasty inkstone style design tends to diversify, the Ming and Qing Dynasty inkstone more exquisite, with some ornamental.

The second aspect, the material is special. Duan inkstone ink like the wind, grinding out the ink is fine and oily, suitable for writing, and does not hurt the brush. The ink inside the ink stone is not easy to dry up, winter meets the cold weather ink in the ink stone will not freeze, summer ink will not rot and deteriorate. These properties of the inkstone are very convenient for the ancient times when material conditions were backward. In addition to good-looking, the inkstone is also very practical.

The third aspect, production is rare, rare is expensive. The mining of ink stone is not simple, to undergo more than a dozen procedures to be mined out to make the stone can be initially carved. Legend has it that "the old pit creeping child pit slant, quarrying people with the credit of the world. Mowing the purple clouds is a pain in the ass, and a thousand dollars is not a luxury." The legend says that the quarrying workers are in accordance with the direction of the stone veins, to the deep mining, can have three or four percent of the stone can be used is already rare. So the ink stone production is small, mining is difficult.

In summary, although the production of inkstone is not high, but because of its excellent performance, so it can leap to the top of the four famous inkstone, the above is my personal views on this, hope to adopt ~
