Pétrole is the French word for (crude) petroleum. The artists' pigment asphalt, sometimes derived from pétrole, is typically thinned with gasoline (petrol). It was formerly used as an alternative to rubber solution (Cow gum) to hold back water-based bleaches and dyes in retouching. It is/was sold by La Pébéo, a major French supplier of artists' materials.
