NARA SUMI / NARA INK
About 1,300 years ago / 700s / Nara Period (710–794)
Japanese ink production expanded in the Nara period as Buddhism and sutra copying created enormous demand. Temples needed reliable writing materials, encouraging the manufacture of solid ink from soot and animal glue. Even after the capital moved, Nara remained an important center serving religious institutions and calligraphers.
In Japan, Nara ink is valued for the many colors hidden inside “black.” The amount of water, grinding time and type of soot can produce bluish, brownish or glossy tones, and calligraphers still choose different ink sticks according to the work.
Unlike most writing materials, ink can improve with age. After careful drying, sticks may be stored for years or decades as the glue gradually changes, affecting flow and color. Fine old ink—koboku—can acquire a prestige almost like aged wine.
