Stone Information
Matrix Granite (often called
Black Matrix or
Granito Matrix) is a high-density natural stone from Brazil, famous for its "liquid metal" appearance with swirling silver-grey and black patterns. While commercially called granite, it is geologically classified as a
biotite gneiss, a metamorphic rock with high-grade mineral banding.
Quarry Information
Matrix is one of the densest and most durable natural stones available, making it highly resistant to mechanical stress.
- Hardness: 6.5 – 7 on the Mohs Scale, providing excellent resistance to scratching and wear.
- Density: 2,623 – 2,745 kg/m³, ensuring high structural integrity.
- Water Absorption: Extremely low, between 0.26% and 0.29%, making it highly stain-resistant.
- Compressive Strength: 195 – 230 MPa, significantly higher than standard quartzites.
- Mineral Composition: Primarily Quartz (55-60%) and Feldspar (20-25%), with Biotite and Mica (5-8%) providing its characteristic metallic shimmer.
