Goat-brain paper is a kind of ancient Chinese fine paper made by coating the mineral-blue paper with a mixture of goat brain and ink that had been stored in a dark place for a while. With a surface smooth as lacquer and shiny like mirror, such a mothproof and long-lasting variety of paper was often used for applying pigments mixed with gold powder. This accordion-fold leaflet inscribed with Buddhist sutras features hand-painted Buddha images in gold as well as page borders composed of hand-made motifs.
