Method for making blocks and plates from pieces of marble and other natural stones

Abstract From the Canadian patent

Pieces of marble or similar natural stone having a plurality of plane faces are stacked in a liquid-tight container. Said pieces are arranged with their plane faces facing each other so as to form a plurality of parallel layers. Thereafter, a vacuum is applied in said container and, while maintaining the latter under vacuum a fluid, hardenable binding composition such as a synthetic resin, is then poured into said container.
