Made with Japanese paper, mizu-hoshi, iwa-enogu, gofun. This is a very beautiful fish, which was apparently called "colored carp" or "flower carp" in Japan. It was also introduced in the previous square panel using the silver leaf sulfurization technique. This work was painted in size F6 using the usual Japanese painting technique of mizu-hoshi and iwa-enogu (mineral pigments). I have painted this composition many times in watercolor. The Nishikigoi carp was arranged from a photograph of carp in Matsumi Park in Tsukuba Science City. Nihonga" is based on a style of painting that has existed for more than 1,000 years, and uses traditional materials that have been cultivated throughout history. It is a technique of painting on Japanese paper, silk, wood, etc., using natural paints such as sumi ink, iwa-enogu (mineral pigments), gofun (gofun), etc., and glue (nikawawa) as an adhesive. Gold and other metal materials (gold leaf, etc.) are also used. Iwa-enogu, made from ores, is a beautiful, sand-like powder. Mizuhigure, made from clay, is a fine, stretchy, fine-particle paint. Artificial versions of iwa-enogu and mizuhoshi egur are also made, and are available in a wide variety of colors. Goko, made from shells, is a white pigment with fine particles.
