Also iwamono Šâ•¨. A paint *enogu ŠG‹ï made from pulverized mineral pigments *ganryou Šç—¿ such as rock, earth and metals. Used in Japanese painting *nihonga “ú–{‰æ and other Oriental painting touyouga “Œ—m‰æ. Mineral pigments are insoluble in water, so they are applied with a binder *baizai ”}Ü of animal skin glue *nikawa äP. Iwa-enogu made from naturally occurring materials include: ultramarine *gunjou ŒQ made from azurite or lapis lazuri; green *rokushou —Πmade from malachite; reds *shu Žé from cinnabar; *taisha ‘ãæÞ from iron oxide; orange *tan ’O from oxidized lead; yellow ochre *oudo ‰©“y made from native earth coloured with hydrated iron oxide, and white *gofun ŒÓ•² from calcium carbonate obtained from shells. Naturally occurring minerals give the paints the glint and transparency of precious stones. The colours are opaque, durable, and relatively resistant to fading. A single type of stone has a richness of colour derived from differences in the sizes of the particles and the inclusion of some extraneous material. Although the number of colour sources is limited, various colour tones are obtained by grinding down the pigment; the finer the grains, the lighter the shade produced. Exposed to heat, the colours deepen, and even longer heating turns them to a shade of black with a hint of the original colour. Iwa-enogu must be totally dry before they can be painted over with another colour, and it is difficult to mix colours because of differences in the weight and size of the particles. In modern times many Japanese painters use synthetically produced mineral-based paints called shin-iwa-enogu VŠâŠG‹ï or jinzou-iwa-enogu l‘¢ŠâŠG‹ï. Paints made from earth materials are also known as doro-enogu “DŠG‹ï.
