Natural Glass is a revolutionary new water-based bio-polymer varnish and painting medium made from milk casein and beeswax, with a few other natural ingredients added to help it remain flexible and tough. 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 re-worked, removed, painted over, layered or used as 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 watercolor 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 easy. Its lustrous surface adds depth to your colors while protecting from scratches and moisture. Pigment brilliance is preserved, you won’t lose your highlights or dull your colors, in fact, pigments become even more luminous.
Like all SpectraFix products, Natural Glass washes up with water, is completely non-toxic with no irritating fumes, and can be used indoors.
