The sole FIGURE is a top plan view of a portion of a slab, showing our new design.

Such a synthetic mold slab may be, for example, thermoformed or otherwise compacted to a selected slab shape from a mixture including particulate mineral material, resin binder, and pigments so that the solid surface portion of the synthetic molded slab is suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

The portion of a slab is flat.
