Abstract
Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a pattern defined by a particulate mineral mix. The pattern includes one or more characteristics that differ from other regions of the slab where the pattern is not present.
Claims19
A processed slab formed from a plurality of particulate mineral mixes, comprising:
- a slab width that is at least 2 feet and a slab length that extends perpendicular to the slab width and that is at least 6 feet, the slab length and the slab width defining a top major surface;
- a first slab thickness at a first slab region defined by a first particulate mix, the first slab thickness extending perpendicular to the slab width and the slab length, the slab length greater than the slab width, the slab width greater than the first slab thickness;
- and
- a second slab thickness at a second slab region defined by a second particulate mix that comprises greater than 30 wt % metal particles in a vein pattern, the second slab thickness extending perpendicular to the slab width and the slab length, the slab length greater than the slab width, the slab width greater than the second slab thickness, the second slab thickness different than the first slab thickness.

- and
- a second pattern defined by a second particulate mix, the second pattern exposed along the top major surface of the slab, the second pattern having a second pattern surface roughness that is different than the first surface pattern roughness,
- wherein at least a portion of the first pattern corresponding to the first pattern surface roughness is recessed from a plane of the second pattern, projects from the plane of the second pattern, or is both recessed from and projects from the plane of the second pattern.
