It covers well even in thin layers and, like other iron oxides, dries well in oil. Mixed with white it gives warm pinks and flesh tones; with blue or black, deep browns. The supplier notes that red iron oxides are compatible with all other pigments.\u003c\/p\u003e\u003ch2\u003eAbout Venetian red\u003c\/h2\u003e\u003cp\u003eVenetian red was originally a natural red earth colored by hematite. By the 18th century it was also manufactured by heating iron sulfate (copperas), and modern versions are often synthetic red iron oxide, as ours is. The name has been recorded as an English color name since 1753. Among red iron oxides it is a warm shade, warmer than English or Indian red.\u003c\/p\u003e\u003ch2\u003eSafety\u003c\/h2\u003e\u003cp\u003eHandle dry pigment with care: avoid breathing the dust and contact with eyes. Wear a dust mask (FFP2\/N95) and gloves when working with the powder, work in a well-ventilated area and wipe up spills with a damp cloth. Do not eat, drink or smoke while working; wash your hands afterwards. Keep away from children and pets. For artistic and technical use only — not for cosmetics, food or tattoos.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eIs Venetian red natural or synthetic?\u003c\/h3\u003e\u003cp\u003eOurs is synthetic red iron oxide, PR101.
