Ink sticks – sumi sticks – are made in China and Japan, and most likely in Korea as well. Bottled ink is also available, but lacks many of the qualities preferred by traditional painters and calligraphers. Pouring ink from a bottle is not the same as being able to take the time grind a fine stick on a lovely stone, to enjoy the task, and focus one’s energy. Most ink is also poorly made, and contains chemicals which can damage a fine brush or stone. It is very important that if you do use bottled ink that you wash your brush thoroughly afterward, blot it, and reshape the point prior to hanging it to dry.
In this video, the artist Hirokazu Kosaka discusses ink sticks. While he does not go into great detail about their production, he does show some interesting elements of their construction and packaging. Opening a pawlonia wood box, he shows a “color” chart for the sumi stick. The light and dark capabilities of the ink are demonstrated on a piece of paper inside the box lid. He also shows the mold used to create the ink stick. Many ink sticks are embossed with symbols or pictures, which are later colored with gold or silver or colored paint.
The quality of a sumi stick varies, from very poor (as is most sold in the U.S.) to student grade, to professional. They also vary in size and shape, from very small to very large and colored. There is some argument as to which is better, the Japanese or Chinese; I have both and will say that the professional quality Japanese sumi is one I prefer. I also have some Chinese ink sticks, and their quality tends to fluctuate. Also, the Japanese ink tends to be a bluer-black color, while the Chinese ink is more brown-black. Both have their beauty.
According to Wikipedia:
Inksticks (Chinese: 墨 pinyin: mò; Japanese: 墨 sumi), sometimes known as sumi (Japanese transliteration), are a type of solid ink used traditionally in several East Asian cultures for calligraphy and brush painting. Inksticks are made mainly of soot and animal glue, sometimes with incense or medicinal scents added. To make ink from the inkstick, it has to be continuouly ground against an inkstone with a small quantity of water to produce a dark liquid which is then applied with an ink brush. Artists and calligraphists may vary the thickness of the resulting ink according to their preferences by reducing or increasing the intensity and time of ink grinding.m Sumi sticks after it has been used), and delivered.
Ink sticks need to age, just as wine. A well-made sumi stick may be very old and very valuable. Commercially, such ink sticks are available, but not readily in the U.S. or Europe. There are various importers, but as the market is limited, they are unlikely to carry the variety available in China or Japan.
Most ink sticks sold in the U.S. are inexpensive ones, whether originating from Japan or China. If you cannot grind a dark ink in a moderate amount of time, if there are grainy particles which scratch your stone, you do not have an ink stick worth using as far as I am concerned.

For us ink stick lovers, it would be sheer heaven to walk into a shop filled with ones to choose!
