Sennelier Oil Pastel is a product that makes use of the components used in all Sennelier colors - top-quality pigments,an extremely pure synthetic binding medium,& mineral wax. The pigments are ground with an inert,non-siccative binding medium that does not oxidize & that has no effect upon either the film stability or the surface. This base is then mixed with wax (neutral pH). The balance of this mix provides Sennelier oil pastels with a unique unctuousness & a creamy texture that allows for a great deal of freedom in pictorial expression. Sennelier Oil Pastels possess an extraordinarily high pigment content,thus providing them with a high coloring & covering potential,excellent brightness,& a high degree of light stability (with the exception of metallic & fluorescent shades). Note: To protect an oil pastel surface from dirt & dust,apply a fixative 8 to 10 days after the work is completed. The fixative will not dry the work. If desired,a final varnish spray can be applied to seal the surface permanently,but this may adversely affect future restoration possibilities.
