Physical properties
Hardness: 7 (Mohs scale); Color: White with grey veining; Luster: Vitreous to dull; Crystal structure: Trigonal (as part of aggregate); Non-porous.
Formation & geological history
Human-made using approximately 90-94% pulverized natural quartz aggregate bound with polyester resins and pigments under intense heat and pressure.
Uses & applications
Predominantly used for kitchen countertops, bathroom vanities, flooring, and wall cladding due to its durability and stain resistance.
Geological facts
Unlike natural stone, engineered quartz is non-porous and does not require sealing. It is one of the most popular surfacing materials in modern residential construction.
Field identification & locations
Identify by looking for uniform patterns, lack of natural pits or fissures, and a 'plastic' feel on the underside. Common in modern home interiors and showroom displays.
