Monocrystalline rounded quartz of alluvial origin, characterized by a silicon dioxide (SiO2) content of 99%. It has a hardness of 7 on the Mohs scale. The material ensures high thermal resistance up to 1730°C without pre-combustion, cold resistance down to -180°C, and mechanical resistance to pressures up to 3000 kg/cm². It is used in water treatment filters and drinking water plants, as well as in flooring and wall coverings, bituminous membranes, cement mortars, and sealants. It is also employed in the production of sanitary ware, sandblasting operations and abrasive materials, refractory products, glassworks and foundries, as well as in the construction of sports facilities, swimming pools, and aquariums.
