The process to convert quartz to a slab/countertop is used by all companies which manufacture engineered stone. This manufacturing process uses raw quartz crystals ranging in size from coarse grains to the size of rock salt. Once the quartz is ground and selected, the crystals are combined with bonding agents (resin) and color, then heated and vibro-compacted to form an impenetrable surface. The resulting slabs are a matrix of 93% quartz and 7% resin binders and pigments … free of fissures and cracks, and impervious to water, moisture, or bacteria and more than twice as strong as granite and less likely to break during fabrication. The one aesthetic characteristic that is prominent with engineered stone is the consistency in pattern.  Although this material is manufactured, it still has the look and feel of natural stone.
