Sennelier is a French brand of art supplies famous for their hand selected pigments. Sennelier La Carte Pastel Paper for all dry drawing techniques: soft pastel, charcoal and graphite. This surface is created with finely ground (pH neutral) natural cork applied to a 360 g (170 lb). (pH neutral) board and creates a soft sand-like surface. All tones are made up of delicate shade gradients, tending towards white.
It took over three years, at the turn of the 20th Century, to formulate the Sennelier range of Extra Soft Pastels "à l'écu" and thus to create one of the largest chromatic range of pastels. Throughout the century, this range of tones has evolved to 525 shades, but the heart of its making remains unchanged.
