Sennelier Mini Oil Sticks 12mL Set of 6 Dark Tones Portrait

SENNELIER Extra-Fine Solid Oil Sticks can be used alone or in combination with to oil colours in tubes. The oil stick colours can be used for an entire painting. They are applied directly to any traditional oil-painting support, such as canvas, wood panel or fine art paper. They need the same archival priming (acrylic gesso or oil ground) that oil paint requires. 

Surfaces:

Before use, the surface film of the oil stick must be peeled off. It will form again after a few days of non-use, protecting and conserving the color. The oil sticks must be applied in a thin film application of no more than 1mm thick. Once applied they can be painted over with oil stick or oil paint and if desired be diluted with turpentine. Oil stick Medium, a colorless oil stick, may be used to produce transparent effects and glazes. Once applied, the oil stick surface will dry in 2 to 5 days, depending on the atmospheric conditions

Varnishing:

If varnishing is desired, you must wait 6 months (as in traditional oil paint) until the colour is completely dry, before giving the painting a final coat of picture varnish. Use a soft brush to varnish so that the oil stick marks are not disturbed. SENNELIER Extra-Fine Solid Oil Stick colours are either opaque (O) or transparent (T) depending on the nature of the pigment in each color. Oil Sticks do not change during storage and require no special precautions except to be kept away from any source of heat, which could adversely affect the stick.
