Precautions:
1. Blue-black ink is ferrous tannin ink. Its main components are ferrous tannic acid and ferrous gallate, and its components will form high-valent iron insoluble in water under oxidation, so the handwriting color will become darker and darker with time.
2. The essence of carbon ink is a suspension of carbon particles, not a solution, so it is easy to block the pen. At the same time, in order to stabilize the addition of organic substances such as shellac, it is easy to deteriorate. However, due to the super stability of carbon, the handwriting of carbon ink can be preserved forever.
3. Different from dye ink, pigment ink is a dispersion composed of particles, the diameter of which is between solution and suspension, which can produce precipitation and produce pigment ink including various colors.
