Physical properties
Hardness: 7 Mohs scale; Color: Grey base with white veining; Luster: Matte to low-gloss; Structure: Cryptocrystalline; Non-porous surface.
Formation & geological history
Engineered quartz is manufactured from crushed natural quartz combined with polymer resins and pigments. It mimics natural marble or quartzite formed by regional metamorphism.
Uses & applications
Countertops, flooring, wall cladding, and interior decoration due to its durability and stain resistance.
Geological facts
Unlike natural marble, this engineered material is resistant to acidic etching. It is one of the most popular surfacing materials globally for kitchens and bathrooms.
Field identification & locations
Identify in a home setting by looking for uniform patterns and lack of natural crystalline defects. It is common in modern residential construction.
