Physical properties
Hardness: 7 (Mohs scale), Color: White with grey speckles, Luster: Vitreous/Polished, Structure: Amorphous/Crystalline mix, Non-porous, high specific gravity.
Formation & geological history
Created through an industrial process called the Bretonstone method involving 90-94% crushed natural quartz mineral mixed with polymer resins and pigments. This specific slab appears modern (last 10-20 years).
Uses & applications
Predominantly used for kitchen countertops, bathroom vanities, flooring, and wall cladding due to its durability and stain resistance.
Geological facts
Engineered quartz is harder and more flexible than natural granite. It was first developed in Italy in the 1960s to utilize waste byproducts from marble and granite quarries.
Field identification & locations
Identify in the field by its extreme uniformity of pattern compared to natural stone and the lack of natural fissures or pits. It will not react with acidic substances like lemon juice.
