Abstract

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

Claims

1. A processed slab, comprising:

a major surface at least 2 feet wide by at least 6 feet long and extending perpendicularly to a slab thickness, the major surface having at least a first pigmented vein extending generally lengthwise from edge-to-edge that separates at least second and third pigmented veins extending generally lengthwise and positioned on opposing sides of the first pigmented vein, wherein the first pigmented vein is defined by a first particulate mineral mix and at least the first particulate mineral mix is separated from and forms a substantially unmixed layer with respect to a second particulate mineral mix defining the second pigmented vein according to a predefined layer pattern such that each of the first and second pigmented veins has a vein thickness equal to and parallel to the slab thickness, the second particulate mineral mix being different than the first particulate mineral mix.

2. The processed slab of claim 1, wherein the third pigmented vein is defined by the second particulate mineral mix.

3. The processed slab of claim 1, wherein the third pigmented vein is defined by a third particulate mineral mix, and at least the first particulate mineral mix is separated from and forms a substantially unmixed layer with respect to the third particulate mineral mix according to the predefined layer pattern.

4. The processed slab of claim 3, comprising a fourth pigmented vein, wherein the fourth pigmented vein is defined by a fourth particulate mineral mix, and at least the first particulate mineral mix is separated from and forms a substantially unmixed layer with respect to the fourth particulate mineral mix according to the predefined layer pattern.

5. The processed slab of claim 1, further comprising a plurality of transverse pigmented veins extending transversely to and intersecting the first pigmented vein, the transverse pigmented veins having a different color than the first pigmented vein.

6. The processed slab of claim 5, wherein at least one of the transverse pigmented veins extends generally widthwise from edge-to-edge.

7. The processed slab of claim 5, wherein the transverse pigmented veins are thinner than the first pigmented vein.

8. The processed slab of claim 1, wherein each of the particulate mineral mixes includes a quartz material and at least one binder.

9. The processed slab of claim 1, wherein the slab comprises at least four differently colored particulate mineral mixes distributed in a series of successive unmixed layers according to the predefined layer pattern.

10. The processed slab of claim 1, wherein the second and third pigmented veins extend generally lengthwise from edge-to-edge of the slab.

11. The processed slab of claim 1, wherein each of the first, second, and third pigmented veins has a vein thickness equal to and parallel to the slab thickness.

12. The processed slab of claim 11, further comprising a plurality of transverse pigmented veins extending transversely to and intersecting the first pigmented vein, the transverse pigmented veins having a different color than the first, second, and third pigmented veins, wherein at least one of the transverse pigmented veins extends generally widthwise from edge-to-edge, and wherein the transverse pigmented veins have a vein thickness less than the slab thickness.

13. The processed slab of claim 1, wherein the major surface of the slab is polished and emulates the appearance of a quarried stone slab due at least in part to the first and second particulate mineral mixes distributed according to the predefined pattern.

14. A set of separately molded processed slabs, each respective slab of the set comprising a major surface at least 2 feet wide by at least 6 feet long and extending perpendicularly to a slab thickness, the major surface having at least a first pigmented vein extending generally lengthwise that separates at least second and third pigmented veins extending generally lengthwise and positioned on opposing sides of the first pigmented vein, wherein the first pigmented vein is defined by a first particulate mineral mix and at least the first particulate mineral mix is separated from and forms a substantially unmixed layer with respect to a second particulate mineral mix defining the second pigmented vein according to a predefined layer pattern such that each of the first and second pigmented veins has a vein thickness equal to and parallel to the slab thickness, the second particulate mineral mix being different than the first particulate mineral mix, and wherein the first, second and third pigmented veins extend substantially lengthwise on each respective slab such that the major surface of each respective slab in the set has similarly positioned and colored substantially lengthwise veins.

15. The set of separately molded processed slabs of claim 14, wherein at least one of the lengthwise extending pigmented veins of each respective slab extends fully lengthwise from edge-to-edge of the respective slab.

16. The set of separately molded processed slabs of claim 14, wherein the major surface of each respective slab of the set further comprises a plurality of transverse pigmented veins extending transversely to and intersecting the substantially lengthwise veins, the transverse pigmented veins having a different color than the substantially lengthwise veins.

17. The set of separately molded processed slabs of claim 16, wherein the transverse pigmented veins of each respective slab are thinner than the substantially lengthwise veins of the respective slab.

18. The set of separately molded processed slabs of claim 14, wherein each of the first, second, and third pigmented veins has a vein thickness equal to and parallel to the slab thickness.

19. The set of separately molded processed slabs of claim 14, wherein the third pigmented vein is defined by the second particulate mineral mix.

20. The set of separately molded processed slabs of claim 14, wherein the third pigmented vein is defined by a third particulate mineral mix, and at least the first particulate mineral mix is separated from and forms a substantially unmixed layer with respect to the third particulate mineral mix according to the predefined layer pattern, and wherein each of the first, second, and third pigmented veins has a vein thickness equal to and parallel to the slab thickness.
