A liquid preparation sprayed over charcoal drawings, chalks, or pastels to prevent smudging. It is effective with monochromatic work, but less so with pastels, because of the inevitable alteration of colour values brought about when it is applied.
There are several different compounds called fixatives:Drawing
In drawing, a fixative is a liquid, similar to varnish, which is usually sprayed over a finished piece of artwork to better preserve it and prevent smudging. Artwork media requiring fixative include drawings done in pencil, charcoal, and pastel. Such a technique requires a workable fixative.
Biology
In biology, a fixative is a solution used to preserve or harden fresh tissue or cell specimens for microscopic examination. Use of fixatives is an important technique in the discipline of cellular pathology.
Embalming
Modern embalming chemicals are fixatives, as were the historical chemicals employed in mummification.
Perfumery
In perfumery, a fixative is a natural or synthetic substance used to reduce the evaporation rate, increase perceived odor strength, and improve stability when added to more volatile components. Some examples of fixatives are sandalwood, musk, Ambergris and orris root. Natural fixatives usually have a fragrance considered a base note, reflecting their low volatility.
