The use and maintenance of famous inkstone;
1, usually storing water.
Ink also needs to be moistened and stored with clear water every day. Ink should not be short of water. People used to call it "nourishing research".
Step 2 use water exchange
Don't be lazy and grind the ink directly with the inkstone, and don't think that the ink ground with tea and sugar water is "unique". When these things are mixed with ink, the color of the ink will be greatly reduced, and no ink will be produced. Hot water damages ink, remember to avoid it.
Step 3 brush your teeth after use
After the inkstone is used up, the remaining ink must be washed off and not condensed on the inkstone. Otherwise, the residual ink will form a slag block, which will hinder grinding and damage the brush strokes and the surface of the inkstone. If mixed with new ink, there is no advantage of inking or inking.
4, new ink light grinding
This new ink has sharp edges and corners. If you grind hard, it is easy to damage the ink surface. When in use, it can be lightly ground.
