Papier-mâché is a sculpting technique that uses wet paper mixed with an adhesive. The paper can either be pulped and used to form a sculptable mass around a wire frame, or spread in strips over a pre-made backing. When the paper dries it forms a hard, light surface. Many Himalayan temple images and cham masks were made from papier-mâché, although due to the perishable nature of the material, fewer of these survive than sculptures in stone or metal.
