Originally developed by Sennelier for Pablo Picasso, Sennelier oil pastels possess an extraordinarily high pigment content that provides them with high colouring, excellent brightness and an unsurpassed degree of light stability (with the exception of metallic and fluorescent shades).
The pigments are ground with an inert binding medium that does not oxidise and that has no effect upon either film stability or surface. This base is then mixed with a neutral PH wax. The balance of this mix provides Sennelier oil pastels with a creamy texture that allows for a great deal of freedom in pictorial expression.
There are 110 classic colours in the range and 10 iridescent colours.
