Precautions:
1, after writing the work, let it dry for 24 hours, so that the ink is fixed and will not run away when mounting.
2. Freezing in winter is a characteristic of traditional ink, so it should be stored indoors above 10℃. If frozen, you can soak the bottle in warm water to melt, and the quality is as good as before.
Never get ink on clothes, otherwise it will be difficult to clean them thoroughly.
Although the ink is easy to use, the discussion is fixed (the ink factory has prepared it when it produces ink). When writing, the ink is too thick, so it is difficult to start the pen and it is easy to lag. The ink is too weak, and the pen will get inked as soon as it is placed on the paper. In short, the color is not suitable, which will affect writing. Therefore, if the ink is thick, add water. If it is weak, it is necessary to study how to make the ink thick and light, so as to write good words.
