The inkstone platform is not only a stationery for the study, but also a rare collection by scholars of all ages because of its firm nature and immortality. The tea tray of Duanyan is often cracked because the inkstone is made from mountains. Duanyan is the first of the four famous inkstones in China, and it is the knot of many people's hearts.
Duan inkstone is not only very valuable since ancient times, but also all famous pits have been "sealed" due to the exhaustion of inkstone materials, especially the old pits have been sealed for many years, and no stone can be recovered. The value of Duan inkstone in all famous pits, such as Laokeng, Mazikeng, Kengziyan, Meihua and Songkeng, is increasing, and these raw materials are becoming more and more precious.
The reason why the Duanyan pit was closed is that the pit was closed and mining stopped because of the tunnel blockage, landslide and government protection. The resources of the inkstone are getting less and less, and all the previously mined inkstones are sold. If one piece is sold, one piece is missing, so the collection value of the Duanyan pit is getting higher and higher, and the appreciation potential is increasing.
