Carton-pierre, was a material used for the making of raised ornaments for wall and ceiling decoration. It is composed of the pulp of paper mixed with whiting (ground calcium carbonate) and glue, this being forced into plaster moulds backed with paper, and then removed to a drying room to harden. It is much stronger and lighter than common plaster-of-Paris ornaments, and is not so liable to chip or break if struck with anything.
