Get your TRACTION back! InstaGrit can be applied by brush to precise areas in your colored pencil, graphite or pastel drawings which have become slick from heavy application and will no longer accept more media. Dries transparent and invisible, but magically picks up color as soon as you pass your pencil over it. InstaGrit is very thin, and does not leave heavy texture marks, instead it dries perfectly flat, giving you a receptive surface without unwanted texture. Works on most supports including all papers, panels, canvas etc. Use InstaGrit for detailed additions or corrections, it can be tinted with watercolor paint to provide a toned background, or paint it on panels or paper for a gritted surface. When applied on top of Natural Glass it permits intricate layering with pencil, pastel or other drawing media, which can then be fixed and sealed.
May be used with graphite pencil to create rich, dark blacks.. much blacker than you can normally achieve just by pressing harder.
Stir very well before using to lift grit sediment into solution.
Totally non-toxic and natural, fully archival and compatible with all drawing media, including colored pencil, soft and oil pastels, charcoal, graphite and much more.
2 oz jar.

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.
