About Red Novgorod earth

Red earths, also called red ochres, are natural mixtures of hematite with clay and sand; the hematite, named after the Greek word for blood, gives them their color. Earth reds of this kind are among the oldest pigments known. The name of this pigment refers to Novgorod, the historic city in northwestern Russia.

Safety

Natural earths can contain crystalline silica: avoid breathing the dust. Handle 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.
