ABSTRACT:
A method of stiffening plastically deformable material, newly forming or formed into a shaped body, is disclosed. The method includes; exposing the material, which includes body-forming matter, polar molecules, and a polymeric agent having a thermal gel point, to electromagnetic radiation within the frequency range 10.sup.7 to 10.sup.13 Hertz. The radiation is applied while plastically deformable material is contained in, or as it emerges from a forming member in the shape of a body.
