Fixative Spray

In drawing, a fixative is a liquid, similar to varnish, which is usually sprayed over a finished piece of artwork, usually a dry media artwork, to better preserve it and prevent smudging.
Modern fixatives are usually alcohol based, and hydrocarbon propelled. Certain manufacturers produce fixatives specified for a certain media only, such as soft pastel fixatives. Modern fixatives are elevated in quality in terms of transparency, colourlessness, age-resistance and UV resistance, which prevents yellowing and fading caused by exposure to light.
