The finished ink must be added with water; The amount of water in the grinding ink itself is the same, and there is no need to add water deliberately.
Reason:
Water must be added to the special ink for painting and calligraphy, otherwise it will delay the use of pens. Because a certain amount of glue is added in the manufacture of ink to prevent precipitation. Therefore, calligraphy lovers must add water when writing with finished ink.
For real calligraphers, they usually grind their own ink when creating, so that the ink is smoother.
Refined ink

As far back as 4 thousand years ago, in addition to adding ink to painted pottery, all-black pottery unique to the East was also used. Oracle Bone Inscriptions's symbols in Shang Dynasty and Oracle Bone Inscriptions were written in ink, and Zhou Qin's documents were written in ink on bamboo slips, wooden slips and silk. However, the ink used in Shang Dynasty and Middle Ages was different from that used after the Eastern Han Dynasty, some were graphite in natural minerals, and some were carbon black ink burned with charcoal.
Raw materials of ink

There are many kinds of soot, including various mineral plants and animal raw materials, which are formed by combustion or thermal decomposition. In addition to animal glue, vegetable gum (Arabic gum) or various synthetic gums such as acrylic gum and polyol resin are also used as glue.
