Inkstick
An inkstick is a solid form of ink traditionally used in East Asian calligraphy and painting. It is primarily made from soot (typically pine soot or lampblack) and animal glue, carefully mixed, molded, and then dried. To create usable ink, the inkstick is ground with water on an inkstone until the desired consistency and darkness are achieved. The quality of the inkstick, inkstone, and water used all contribute to the final quality of the ink produced. Different varieties of inksticks exist, often distinguished by the source of the soot, the type of glue used, and the addition of fragrances or medicinal ingredients. The practice of grinding ink from an inkstick is a meditative and integral part of the artistic process in East Asian traditions.
