The material used for thepainting or drawing remains the same since noneof the ingredients undergoes any changes overtime. There is no drying process. An untreatedwork is not smudge-proof. This can be remediedby varnishing a work. This should not be donewith a varnish based on solvents since oil pastelsdissolve in white spirit and turpentine.
