We offer another handmade pastel specifically formulated with pumice to produce a totally new pastel experience. Diane Townsend originally created these pastels to eliminate the need for fixative. Terrages Pastels are made with extra fine pumice to allow it to "bite" into the surface of the paper and provide a base coat. This base coat provides a surface similar to a sanded pastel paper, even on smoother papers. The pumice base coat allows an artist to apply multiple top layers of softer pastels. Available in a beautiful range of 177 colors in irregularly shaped chunks. Pumice pastels are made by hand so shapes and sizes will vary but average around 1-3/8" x 1" x 3/8". The addition of pumice makes them vey sturdy and ideal for large scale works.
