Physical properties

Hardness 7 (Mohs scale), typically uniform color with particulate patterns, vitreous luster, lacks natural cleavage, high durability.

Formation & geological history

Manufactured composite material consisting of crushed quartz (about 90-95%) bound together with polymer resins and pigments.

Uses & applications

Widely used in construction for countertops, flooring, and wall cladding due to its non-porous nature and stain resistance.

Geological facts

Engineered quartz was developed in the 1960s by the Breton company in Italy and has become a standard in modern interior design.

Field identification & locations

Identified by its highly uniform, repeating particulate pattern, lack of natural flaws, and polished surface that feels cooler than plastic but less cold than natural stone.
