Abstract
Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. The first particulate mix includes greater than 50 weight percent of first metallic particles.
Claims18
A processed slab formed from a plurality of particulate mineral mixes, comprising:
- a slab width that is at least 2 feet;
- 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 slab thickness that extends perpendicular to the slab width and the slab length, the slab length greater than the slab width, the slab width greater than the slab thickness;
- and
- a first pattern defined by a first particulate mix, the first pattern exposed along the top major surface of the slab, and the first particulate mix comprising first metallic particles having a first mesh size;
- a second pattern defined by a second particulate mix;
- wherein the first pattern defines at least one vein having a first measured gloss at 60 degrees of 75 or greater;
- and
- wherein the second pattern defines at least one region having a second measured gloss at 60 degrees that is different than the first measured gloss.
