It has high tinting strength and hiding power, good chemical resistance and stability to light, and is insoluble in water. Etc.

Other pigments can also be used to make ink, but their hues, opacity, weight and durability are not as good as cinnabar. As for the non-red ink you mentioned, it is for special purposes. Cinnabar can only make red ink pad. Good ink should be done without maintenance. As long as it is densely dust-proof after use, it can be placed indoors at room temperature. It is not necessary to have a slight oil leakage for a long time. You can use the ribs (distributed sticks) slightly before use (following one direction).
