SpectraFix is a casein-based pastel fixative that utilizes milk protein and grain alcohol to provide a non-toxic, fully archival fixative for pastel, charcoal, conte, watercolor, gouache and multi-media techniques. It holds and protects media without darkening or dulling colors. It can also be used under oil paintings to hold a preliminary charcoal or pencil sketching and provide a barrier between the oil paint and the drawing. It is all natural, odor-free and can be sprayed indoors while without obnoxious odors or unhealthy fumes. 2 oz. bottle, and is reconstituted with the addition of alcohol. The concentrate can also be used to increase the holding strength of the ready-made SpectraFix, and is also great for those who would like a formulation that contains more alcohol for evaporative reasons. Spray cap not included.
