Generally, it is best to use that kind of old inkstone, which is actually a big stone, hehe ~ ~
Then, pour some water first, and then start running in the direction of time. Note: don't be fast, be slow ~ ~ You can get a faint fragrance from the ink. When you feel a certain time, you can dip a brush in some ink and try the consistency on the paper. If appropriate, you can use it. If it's thin, grind it for a while.
