These magnificent paints are designed to look and work just like traditional oil paint, but they're a bit special. You can use them without hazardous solvents - they're happy being thinned down and cleaned up with water. They're especially good for artists who share a workspace or don't want solvents in school or at home.
French Ultramarine is a rich transparent blue. It was created by French chemist Guimet in 1828 as a synthetic but chemically identical alternative to the expensive pigment derived from Lapis Lazuli.
