Developed and handmade in England by artist John Hersey, Unison pastels are simply beautiful. They combine rich pigmentation and excellent handling qualities with an entirely new approach to light. Unison Colour Pastels are made with mixtures of pure pigments containing as little white or black as possible. The result is a unique clarity of color. The pigments are mixed by hand in large mortars. The binder, in most cases, is simply water, with a minimum of gums added when necessary. The pastels are then hand-rolled, in batches of one to two hundred sticks at a time, and air-dried. Unison pastel sticks measure 2” x ½”, shorter and thicker than most, with a softer, smoother texture. They glide on the paper and are not crumbly or brittle.
