Physical properties
Hardness: 7 (Mohs scale), Color: Brown/Grey with speckled inclusions, Luster: Vitreous to glossy, Crystal structure: Trigonal (as individual quartz grains), Specific Gravity: ~2.65
Formation & geological history
Man-made engineered stone created by combining approximately 90-95% crushed natural quartz with 5-10% polyester resin binders and pigments. This specific texture is a modern industrial product.
Uses & applications
Primarily used for kitchen countertops, bathroom vanities, flooring, and wall cladding due to its non-porous and scratch-resistant nature.
Geological facts
Unlike natural stone slabs, engineered quartz does not require sealing and is highly resistant to staining and bacterial growth.
Field identification & locations
Identify by the uniform, repetitive pattern of crushed grains and the absence of natural veins or fissures. Often found in modern residential and commercial interiors.
