The ink output of different quality ink sticks is different, and the lowest ink output is 20 grams from 4 grams of ink sticks, which means that solid ink sticks can output ink at a ratio of less than 1:5. The ink discharge ratio of the second ink stick is 1: 15. In addition to writing calligraphy works, you can also use ink sticks or ink blocks to grind ink.
Personally, I suggest that learning calligraphy is best to buy ink, which can save a lot of time. Even if you buy ink sticks (blocks), you should choose coarse ink sticks of more than 4 taels (120g), which has a large contact area with the inkstone and produces more ink. Compared with small ink sticks, it can save time.
