Stone which is produced by sawing top and bottom beds to a desired height +/- 1/8”, then placing the slab in a hydraulic press “Guillotine”. The Hydraulic press has upper and lower teeth mounted in a straight row on jaws one above the other. As pressure is applied, the stone will separate from the slab at its weakest points, thus producing a naturally rough surface. The break produces a slight concave or convex shape. The stone is cut to length in the field by the installer. The face may be dressed and the ends finished the installer.
