Oil-based colored pencils are made from pigments, solid oils and binders. Oil-based pencils usually have better lightfastness ratings than wax-based. Work done with oil-based pencils does not get wax bloom because the pigment cores are not made from wax. They are available in sets and open stock.
German-made Polychromos pencils are an oil-based pencil that has excellent lightfastness ratings and are extremely break-resistant. They hold a point well and are good for detail work or coverage. They blend well with layering, burnishing and blending with solvents. These pencils have a 3.8 mm lead and are encased in cedar wood with a bonding agent to make them resist breaking. A mid-range priced pencil, well worth the cost.
Available in sets of 12, 24, 36, 60 and 120; open stock.
