Sennelier Oil Pastel come in a range of 120 lightfast colours. SENNELIER OIL PASTELS Parisian painter Henri Goetz approached Henri Sennelier the famous artist materials manufacturer, about creating a wax colour stick for his friend Pablo Picasso. Picasso, a long-time Sennelier customer & a frequent visitor to their store across the street from the Louvre museum, was looking for a medium that could be used freely on a variety of surfaces without fading or cracking. Their collaboration produced the incomparable Sennelier Oil Pastels. Originally available in a palette of 48 classic hues, the colour selection was expanded twice; in 1975 with the addition of 5 metallic hues, & again in 1980, when 16 iridescent & 6 fluorescent hues were created. Beyond these classic hues a selection of unique shades is available, & in particular a graduation of 10 greys, required for a balanced palette. This evolution is the fruit of a long-standing collaboration with European & North American painters, who have worked with Sennelier in developing an exceptional palette of shades. The Sennelier Oil Pastel is a product that makes use of the components used in all Sennelier colours: finest top quality pigments, an extremely pure synthetic binding medium & mineral wax. The pigments are ground with an inert, non-siccative binding medium that dows not oxidise & that has no effect upson either film stability or surface. This base is then mixed with wax (neutral p H). 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. The Sennelier Oil Pastels possess an extraordinarily high pigment content, thus providing them with a high colouring & covering potential, excellent brightness & a high degree of light stability (with the exception of metallic & fluorescent shades). The remarkable properties of these components, along with their precise dosage, provide Sennelier Oil Pastels with unique properties, making the brand a world-recognised reference. Medium: 40
