red ink paste

Red ink paste is a thick, viscous substance used in traditional East Asian calligraphy, painting, and seal stamping. Made primarily from finely ground cinnabar (mercury sulfide) or other mineral pigments mixed with plant or animal adhesives, it forms a bright red, durable ink. When applied with a seal (chop), it transfers the stamp's carved design onto paper or other surfaces. The paste’s consistency ensures that the seal leaves a clear, precise impression, symbolizing authenticity or authority, often used in official documents, artwork, and personal signatures.
