ABSTRACT:
Method and apparatus for creating and maintaining frosted sculptures are described. In a preferred embodiment, the apparatus includes an armature, or a length of conduit freely formed into a desirable shape, having circulated therethrough, by reverse-sublimation means operatively coupled therewith, a freezing agent. The reverse-sublimation means preferably includes pump means, condensation means and metering means, and is capable of removing the sensible heat and the latent heat of fusion from water vapor surrounding the armature, thereby to promote growth, on the exposed surface of the armature, of a thick layer of rough-textured frost.
