Physical properties

Hardness: 7 (Mohs scale), Color: Creamy white with fine speckling, Luster: Dull to matte (based on finish), Crystal structure: Cryptocrystalline particles in resin binder, Specific gravity: 2.65

Formation & geological history

Formed through industrial manufacturing by combining approximately 90-95% crushed natural quartz with 5-10% polyester resin binders and pigments. Mimics the metamorphic process of natural quartzite.

Uses & applications

Predominantly used for kitchen countertops, bathroom vanities, flooring, and wall cladding due to its non-porous and durable nature.

Geological facts

While natural quartzite is a metamorphic rock formed from sandstone, engineered quartz is a man-made product. It is often preferred in modern construction because it does not require sealing and is highly resistant to stains and scratches.

Field identification & locations

Identify by looking for uniform patterns and a lack of natural 'veining' typical of marble. In the field, it sounds high-pitched when tapped. Commonly found in residential and commercial interior design showrooms.
