  • Process for artificially forming rocks
    Patent number: 3950477
    Abstract: A process for artificially forming rocks is described. The process provides for forming a rubber film mold of the surface of a natural rock. The rubber film mold is then placed on a bed of flowable supporting elements which are distributed to support the underside of the cavity of the rubber film mold such that it assumes a desired contour or shape. A filling of concrete poured into the cavity of the mold upon hardening and being turned over provides an artificial rock whose surface has the characteristic markings of the natural rock but may have any desired different overall contour or shape.
