Sennelier uses an authentic formulation of the classic egg tempera used by artists since the Renaissance. It is a perfect choice for artists seeking a highly pigmented, professional quality alternative to oil paints. Sennelier Egg Tempera are water-soluble, highly archival, and made with premium pigments assuring unequaled vibrancy and brilliance for detailed and complex effects such as fine art painting, restoration and icon painting. They are water-resistant and non-yellowing, with a satin matte finish. The paint can be worked with a brush or a palette knife (diluted with water) on non-greasy supports like acrylic primed canvas or paper.
