An artificial stone slab comprises a plurality of coated lumps of composite stone material, wherein at least a first set of the plurality of coated lumps are substantially in contact with one another, and wherein at least a second set of the plurality of coated lumps are spaced apart by one or more fillers. An engineered stone slab comprises a plurality of coated lumps of composite stone material, wherein at least a portion of the coated lumps comprise an inner core having a first color and an outer layer having a second, different, color.

Artificial marble, and system and method of producing artificial marble

An engineered stone slab has coated lumps of composite stone material, wherein at least a portion of the coated lumps comprise an inner core having a first property and an outer layer having a second property. The property may include color, texture, density, chemical composition, hardness, porosity or any combination thereof.

Artificial marble

Artificial marble, and system and method of producing artificial marble. A method of producing a stone slab comprises: placing into a frame a plurality of coated lumps of composite stone material; removing substantially all air among the plurality of lumps; pressing the content of said frame; and curing the content of said frame to form the stone slab. An artificial stone slab comprises: a plurality of coated lumps of composite stone material which are substantially in contact with one another.

A method for the preparation of an engineered stone slab having coated lumps of composite stone material, the method comprising: scooping a first inorganic particulate material and a polymer material to produce lumps of composite stone material; mixing a second inorganic particulate material with the lumps to produce coated lumps; and adding one or more colorants to the first inorganic particulate material, to the second inorganic particulate material, or to both the first and second inorganic particulate materials.
