Now you can spray your Natural Glass Varnish onto delicate, easily reactivated media such as gouache or watercolour to give your artwork a protective coating that deepens your colours while protecting it from scuffs.

The 10 oz refillable aerosol provides a fine spray with minimal effort, and the nozzle can easily be cleaned if the material dries in the orifice.

Natural Glass is a revolutionary new water-based bio-polymer varnish and painting medium made from milk casein and beeswax.

It has a few other natural ingredients added to help it remain flexible and rigid. Fast drying to a water-resistant, semi-gloss film, Natural Glass works beautifully as a varnish or medium for all painting and drawing media (not oil pastel) and on virtually all supports, including canvas, paper, Yupo, ceramic, stone, glass, leather, fabric (not washable), wood, gourds, jewelry, and other materials.

It can be reworked, removed, painted, layered, or used as a pouring medium. The dried surface remains wonderfully non-sticky to the touch and does not require Glassine or other separating films to prevent two coated pieces from sticking together. It may be gently wiped with a lightly dampened cloth to remove dust or soil.

Pastel and watercolour artists no longer need to frame their work under glass! No more annoying reflections and glare, concerns about breakage and expense; Natural Glass makes shipping and hanging a show easily.

Its lustrous surface adds depth to your colours, protecting it from scratches and moisture. Pigment brilliance is preserved; you will not lose your highlights or dull your colours; pigments become even more luminous. For best results, apply over a pastel painting that has been sprayed with SpectraFix Degas Fixative or FinalFix.

Like all SpectraFix products, Natural Glass washes up with water, is completely non-toxic with no irritating fumes, and can be used indoors.
