Abstract
An artificial decorative rock of foamed synthetic plastic having a body with an outer surface resembling the concavities and convexities of a natural rock has its outer surface coated with a strengthening layer of epoxy resin filled with hard sand-like particles which give the outer surface a rock simulating, grained texture. By forming a hollow within the surface of one body to complimentarily accommodate the outer surface of another body, one or more artificial decorative rocks can be nested, one within the other. By further shaping the uppermost outer surface of such hollow body to provide a stable support base, the body with the hollow extending upwardly can serve as a container.
