Beijing's "Yidege" ink has a production history of more than 100 years. During the Tongzhi period of the Qing Dynasty, a scholar named Xie Songdai from Anhui Province went to Beijing to take the exam, but failed in Sunshan. He felt that studying ink was too time-consuming and delayed his answer. He thought at the time, if he could produce a kind of ink that could be used directly for writing, which would save time and effort, wouldn't it be possible to "use one technique for the whole world"? So after many experiments, he finally used oil smoke and other auxiliary materials to make ink with the same effect as ink blocks. Once on the market, it was welcomed by literati. In the fourth year of Tongzhi, Xie Songdai opened the first shop for the production and operation of ink at No. 44 Liulichang, Beijing. The name of the shop was "Yidege", and he wrote a plaque by himself and hung it in front of the door. This is the origin of "Yidege" ink. Xie left no children. After his death, the shop passed to apprentices. Later, the reputation of "Yidege" improved day by day, and the scale of production and operation continued to expand. Branches were opened successively in big cities such as Tianjin, Shanghai, Xi'an, and Zhengzhou, and the business became more prosperous. Features: It has the characteristics of high concentration, deep color, bright ink mark, easy drying after writing, and suitable for rubbing. It has been tested by famous painters and calligraphers and the effect is very good. Technology: "Yidege" ink is made of Sichuan high-pigment carbon black, bone glue, borneol, musk, and phenol as raw materials, and is carefully processed using traditional techniques. Sichuan's high-pigment carbon black is deep and bright; bone glue has buoyancy, which makes the ink stick to the paper without being obliterated; borneol and musk are spices, with a refreshing fragrance; phenol is a preservative, which makes the ink not rotten or smelly after long-term storage, and can be used all year round.
