Abstract
Abstract A composition comprising a dextrin incompatible polyvinyl acetate emulsion, glycerin and dextrin exhibiting excellent molding and/or coloring properties for such uses as a novelty item, a molding compound, an artist''s tool, a transfer medium and an exercising device. The composition may upon prolonged exposure to air, dry to a semihard condition and, if desired, the material can be made soft again by immersing it in water and kneading the water into it. The composition may contain suitable coloring constituents to allow the color to be transferred from the composition to another surface it comes in contact with, such as paper or canvas. Also, indicia may be placed on the material by external means and such indicia transferred or printed to another surface.
