Engineered Stone

Raw quartz crystals ranging in size from coarse grains to the size of rock salt are ground and selected; the crystals are combined with bonding agents (resin) and color; then heated and vibro-compacted to form an impenetrable surface. Quartz slabs are a matrix of 93% quartz and 7% resin binders and pigments. Industry-wide, all quartz countertops are made with 93 percent quartz or they cannot claim the hardness, durability, or impermeability of a true quartz surface. The manufacturing process is a controlled process with strict quality-control measures. Production process ensures that slabs are identical in color and texture. The slabs are free of fissures and cracks, and impervious to water, moisture, or bacteria.

Color and Appearance

To the untrained eye, quartz surfaces appear to be natural stone. Engineered stone displays a "consistent variability" or mottling in color and texture throughout a quartz countertop. The actual appearance of the quartz surface varies depending on the size and mix of the granules. Smaller, finer crystals give a more uniform appearance, while larger ones provide a more mottled look. Quartz surfacing is available in colors not found in nature, as the crushed stone is generally mixed with pigment. Take advantage, and choose a color that dazzles while still looking like stone. In addition to granite, some manufacturers produce engineered stone that looks like marble, travertine, concrete, and other natural stone.

Care and Maintenance

Quartz polished surfaces are non-porous, thus do not require sealants. It is resistant to stains caused by wine, fruit juices, liquid food coloring, tea, nail polish and remover, and felt-tip markers. Its non-porous nature is also extremely hygienic, making it a food-safe choice.

Though the quartz surface can briefly tolerate moderate temperatures for a brief time, it can be damaged by high heat and prolonged exposure to heat. Use a hot pad or trivet when placing a hot pan on it.

No surface is indestructible, though. As with any other stone or surface material, strong chemicals and solvents used for cleaning will damage the surface.

Continuous long-term exposure to direct sunlight (UV rays) may result in slight discoloration of Quartz Stone countertops. Most indoor applications will not apply.
