On any surface, oil pastels can be easily blended using cotton buds, tortillons or paper towels. The oil does not dry, but remains soft so that it can be reworked and more layers can be added over a long period of time. The Arty Factory's website includes a step by step guide of how the image below was achieved using this technique.
Oil pastels can also be used to create a wash by moistening with solvents, or to add final surface touches to an oil or acrylic painting. Finished work should always be kept away from heat and framed in glass to prevent any damage.
We have a large range of oil pastels, blending and scraping tools and surfaces for oil pastels available on the George Weil website.
