Abstract
Lead is replaced by a mixture of minerals or of heavy materials, e.g. Ba, steel granules amalgamated by a natural or synthetic binder such as polyester resin, cement or plaster; this malleable mixture is cast in a frame which forms the door frame and is hardened by polymerisation or drying.
