Made of hemp paper and mizu-hoshi. It seems that a spotted species produced in the Edo period spread to Europe under the name of "Chameleon plant" and was reimported to Japan. I have actually grown it. Japanese painting 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. The technique involves 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.
