Crafted with pure pigments and mineral wax, Sennelier Oil Sticks offer artists a revolutionary new approach to oil painting. These convenient sticks can be easily handled and applied to conventional oil painting surfaces such as canvas or paper. With maximum lightfastness and exceptional color vibrancy, these sticks are designed to extend expressive capabilities and allow for a heightened level of spontaneity in painting. For best results, apply in a thin film of no more than 1mm thickness, which can be layered and thinned with petroleum or turpentine as needed. With a drying time of 2-5 days depending on thickness and environmental conditions, these paints can also achieve transparent or glazing effects with the use of clear mediums. Offering both opaque and transparent shades, Sennelier Oil Sticks are a high-quality, professional choice for oil painting and can be stored without special attention. After a drying period of at least 6 months, the painting can be finished with an oil paint varnish.
