Used on their own or ideal for mixed media works they can be used on a multitude of surfaces and can be re-worked with solvents, brushes or painting knives.
The pigments are ground with an inert, non-siccative (non-drying) binding medium that doesn't oxidise and that has no effect upon either film stability or surface. This base is then mixed with neutral pH wax.
The pastels have a high degree of light stability (with the exception of metallic and fluorescent shades).
Developed in response to a request by Pablo Picasso, (a long-time Sennelier customer and a frequent visitor to their store across the street from the Louvre museum), who was looking for a medium that could be used freely on a variety of surfaces without fading or cracking.
In 1949, Parisian painter Henri GOETZ approached SENNELIER , about creating a wax colour stick for his friend PICASSO.
Their collaboration produced the incomparable SENNELIER oil pastels. Originally available in a palette of classic hues, the colour selection was expanded with the addition of metallic and iridescent hues.
