Ink usually consists of pigment, oil and plant fiber. The mixing of oil, pigment and fiber is only a physical reaction, so it will delaminate if it is left for a long time. Light pigments will float slowly with the grease, while heavy pigments will sink slowly.
With the extension of time, delamination will become more and more serious. Over time, the surface of the inkpad will appear oily paste, rancid and become sticky and thick. The sinking heavy color paste gradually caked and hardened.
This change bruised the fiber to varying degrees, and finally caused the fiber to rot, and the inkpad turned into a lump or a thick color paste, which could not be used. In order to keep the inkpad in the best condition all the time, it must be turned over correctly often. Adjust it at least once every three months.

Characteristics of inkpad:
1, good shielding performance. Simply put, cover the wok on the ink, and the printed part can cover the color of the ink. Hold the paper under strong light, and the printed part is opaque. Usually, the stamp pad of calligraphy and painting has good shielding, but also has a heavy three-dimensional sense.
2. Good printing and reproduction ability. If the reduction ability is not good, then Zhu Wen will become thicker, Bai Wen will become thinner, and the edge of the seal will get stuck and blurred.
3. Good transferability. That is, it can be dipped quickly and evenly by the seal, and then pressed evenly on the surface of the medium by the seal.
4, the color does not float or stagnate, lasting. This is mainly because in modern times, organic pigments or other materials are mixed in the production of inkpad, which causes the color to be too bright or uneven, and even reduces the color of calligraphy and painting works. However, the color retention of synthetic pigments is limited, so an excellent ink pad for painting and calligraphy should be made of pure cinnabar.
5. Stable physical and chemical properties. That is, under normal use and preservation, it will not dry, dilute or even deteriorate quickly. At the same time, when the environmental temperature difference is large, the personality changes little.
