Pure, brilliant colors in the form of soft pastels for anyone who wants to emulate the artist-in-training. Van Gogh's slender, rounded pastels are ideal for using the edges for details or the sides for broad expanses. High-quality pigments and kaolin clay combine to create this product with easy color transfer and a velvety finish that is less likely to chip. The pigments used are free of heavy metals: lead, cadmium, and cobalt. Pastels work beautifully on rougher surfaces to which the pastel can adhere, such as paper, cardboard, stone, asphalt, or wood. Pastel drawings and paintings can stain, and applying a coat of fixative to a finished artwork is recommended. The colors have a lightfastness rating ranging from good (25-100 years under museum conditions) to excellent (100+ years under museum conditions).
