Black Granite From Africa
Products Description

practical and affordable black granite
African Black Granite, renowned for its deep, uniform black hue and exceptional durability, is a premium natural stone prized in architecture and design. Originating from quarries across Africa (notably Zimbabwe, South Africa, and Angola), this igneous rock combines aesthetic appeal with unmatched functionality.
1. Texture & Composition
Mineral Makeup:
Primarily composed of quartz, feldspar, and biotite mica, giving it a fine to medium-grained texture with subtle crystalline speckles.
Color & Finish:
Jet-black base with occasional silver or gold mineral flecks. Available in polished (glossy), honed (matte), or flamed (textured) finishes.
Density:
High density (2.95–3.00 g/cm³) ensures minimal porosity and resistance to staining.




2. Performance Characteristics
- Hardness: Scores 6–7 on the Mohs scale, making it highly scratch- and abrasion-resistant.
- Heat Resistance: Withstands extreme temperatures, ideal for kitchen countertops near stovetops.
- Weather Resistance: Non-porous when sealed, it resists UV fading, frost, and acid rain, suitable for outdoor use.
- Low Maintenance: Impervious to bacteria and mold growth with proper sealing.
3. Applications
Indoor Uses:
- Countertops (kitchens, bathrooms).
- Flooring, wall cladding, and staircases.
- Fireplace surrounds and decorative accents.
Outdoor Uses:
- Paving, pool coping, and garden edging.
- Monumental structures, memorials, and exterior facades.
- Commercial Projects: Hotel lobbies, corporate offices, and luxury retail spaces.
4. Care & Maintenance
- Daily Cleaning: Use pH-neutral soap and warm water. Avoid abrasive scrubbers or acidic cleaners (vinegar, bleach).
- Sealing: Apply a penetrating sealer annually to maintain stain resistance.
- Stain Removal: Blot spills immediately. For oil-based stains, use a poultice of baking soda and water.
- Avoid Impact: Though tough, sharp blows may chip edges.
5. Key Considerations
- Installation: Requires professional handling due to its weight. Ensure subflooring is level and reinforced.
- Seams: Visible seams may appear in large installations; discuss layout preferences with fabricators.
- Thermal Shock: Avoid sudden temperature changes (e.g., placing hot pans directly on cold stone).
