She inkstone began in the Tang Kaiyuan period. According to the Five Dynasties' Emotions, the "Longlin Yueyan inkstone" given by Emperor Xuanzong of Tang Dynasty to Prime Minister Zhang and Zhang in the second year of Tang Kaiyuan was a precious Venus inkstone, which was produced in Zhangzhou. It can be seen that she Yan has been circulating for at least 1200 years.
Because Bao Qingying's inkstone is meticulous in texture, firm as jade, and silent in grinding ink, it won the favor of Yuan Zong Li Jing in the Southern Tang Dynasty, so he set up an inkstone service in Zhangzhou and recruited Li Shaowei, a master inkstone worker, as an inkstone service officer. Specializing in making inkstones. Li Yu, the queen of the Southern Tang Dynasty, said that Honesty Hall Paper, Li and Jujube Core Ink were the best in the world, making them famous all over the world. At the end of the Five Dynasties, there was war in the south of the Yangtze River, the inkstone pit was flooded, and the inkstone industry was declining. It was not until the Song Dynasty that Qian Zhi, a captain, went to Shexian County to work, sent someone to find the submerged inkstone pit and took measures to dredge the stream. Shi Naian didn't come back, and inkstone industry rose again. Later, during the Jiayou period, migrant workers were recruited to dig. As a result, the production of she inkstone once again showed a prosperous scene, with continuous fine products, and a number of ink stone carving masters represented by Zhou Quan emerged. During this period, some monographs on ink reception, such as "Ji Pu", "Ji" and "Ji", also came out one after another. Today, in the Anhui Provincial Museum, there are still a number of Song Dynasty inkstones unearthed after liberation. The stones are firm and fine, the carvings are simple and elegant, and there are no complicated ornamentation, which is refreshing and pleasing to the eye.
It belongs to Sinian system after its geological age, and it is a kind of argillaceous clay rock one billion years ago. The geological age of Duanshi in Guangdong is Devonian, which is a kind of argillaceous limestone 400 million years ago. The average hardness of stone is about four degrees, which is 0.5 degrees higher than that of end stone. Because it moistens Shi Jian, it has the advantage of "Su Mo for many years, a drop of jade-like stone embellish", which is beyond Duan's reach. There are many poems praising She Yan in history. For example, Su Shi, Huang Tingjian, Mi Fei and Cai Xiang, the four great calligraphers of the Northern Song Dynasty, all spoke highly of She Yan. Su Shi said in a poem: "Luo Jiao is flat, and the rhinoceros wall of rice pills covers the clouds. People sleep in the afternoon window and listen to the sound of the west wind. " Look at the poet's infatuation with She Yan. Cai Xiang, a calligrapher with a bachelor's degree in Duanming Temple, once got an inkstone and said happily, "Jade is pure, pure and refined. The spirit of ink is silent and smells like incense. It is willing to compare Baoyu inkstone to a priceless jade, which shows how precious and rare it is to have a pair of fine couplets.
