Diane Townsend Terrages pastels were originally developed to meet the desires of pastel painter Wolf Kahn. Each contains finely ground pumice stone that plows into the paper, creating a toothy surface on which to transfer complex layers of color and create a luminous sensation of depth and space. Terrages are formed into substantial rectangular slabs that can accept a more forceful application without crumbling. Made from the purest pigments available, they contain no chalks or fillers. Each pleasing, one-of-a-kind pastel measures approximately 1-3/4" L X 1" W x 1/4" thick (44 mm X 25 mm X 6 mm). Individual colors are available in several shades. Newly formulated Terrages Pastels adhere better and produce less dust than previous formulations. Now heavier and stickier, each pastel incorporates a binder and less pumice than before. This reduces the amount of dust released into the air, onto fingers, and onto other surfaces — extending the life of the pastels and making them more economical to use. Metallic and pearlescent colors are especially improved by the new formulation.
