A transparent or semi-transparent animal glue, used as a binder *baizai ”}Ü, and an adhesive. Nikawa is durable and elastic, although it loses flexibility with age. It is made from the skins, bones, tendons and intestines of animals or fish skins and bones, which are boiled in water to extract gelatin. Excess water is evaporated away, and after cooling leaves a jelly-like glue. Nikawa does not dissolve in cold water, but can be dissolved when heated. A solution of a few percent concentration is used in Japanese painting *nihonga “ú–{‰æ to adhere the pigments *ganryou Šç—¿ and fix them to the picture surface. Nikawa is mixed with alum to make *dousa âH… for sizing paper and is used as a primary coat in oil painting, abura-e –ûŠG. Nikawa has many uses as an adhesive for wood, paper and cloth, and acts as binder for substances such as the white pigment *gofun ŒÓ•², and *tonoko “u‚Ì•², applied to statues before painting.
