Abstract

Claims (32)

1 . 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.

2 . The processed slab of claim 1 , the first particulate mix further comprising second metallic particles having a second mesh size different than the first mesh size wherein the first metallic particles make up greater than 10% by weight of the first particulate mix.

3 . The processed slab of claim 2 , wherein the second metallic particles make up greater than 40% by weight of the first particulate mix.

4 . The processed slab of claim 1 , wherein the first metallic particles are between 140 US mesh and 400 US mesh.

5 . The processed slab of claim 2 , wherein the second metallic particles makes up greater than 10% of the overall weight percent of the processed slab.

6 . The processed slab of claim 2 , wherein the first metallic particles and the second metallic particles are a same material.

7 . The processed slab of claim 6 , wherein the first metallic particles and the second metallic particles are stainless steel.

8 . The processed slab of claim 6 , wherein the first metallic particles and the second metallic particles are selected from the group consisting of copper, brass, nickel, and aluminum.

9 . The processed slab of claim 1 , wherein the first pattern exhibits an average gloss value greater than 80 and an average reflectance greater than 15.

10 . The processed slab of claim 1 , wherein the first particulate mix comprises greater than 30 weight percent of first metallic particles.

11 . 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 greater than 30 weight percent of first metallic particles;

a second pattern defined by a second particulate mix;

wherein the first pattern corresponds to a first region exhibiting a first average reflectance haze, and the second pattern corresponds to a second region exhibiting a second average reflectance haze, and

wherein the first average reflectance haze is greater than 10 and the second average reflectance haze is less than 8.

12 . The processed slab of claim 11 , wherein the first metallic particles are stainless steel particulate having a specified size between 50 US mesh and 140 US mesh.

13 . The processed slab of claim 11 , wherein the first metallic particles are selected from the group consisting of copper, brass, nickel, and aluminum.

14 . The processed slab of claim 11 , wherein the first pattern defines at least one vein having a measured graininess, S_G, a measured sparkle index, S_i, and a measured sparkle amount, S_a, wherein the sum of S_G, S_i, and S_a, is greater than 35.

15 . The processed slab of claim 11 , wherein the first pattern defines at least one vein having a measured gloss at 60 degrees of 75 or greater.

16 . The processed slab of claim 1 , wherein the first pattern corresponds to a first region exhibiting a first average reflectance haze, and the second pattern corresponds to a second region exhibiting a second average reflectance haze, and wherein the first average reflectance haze is different than the second average reflectance haze.

17 . The processed slab of claim 11 , wherein the overall weight percentage of metal of the finished slab is greater than 2 wt %.

18 . The processed slab of claim 11 , wherein the first particulate mix comprises greater than 10% by weight of the first metallic particles.
