Description
Appearance (Color, Pattern, Texture)
Color: Soft cloudy grey base, ranging from light to medium tones.
Pattern: Characterized by distinctive light and dark wooden texture-like diagonal veins, creating a natural, flowing pattern reminiscent of wood grain or aurora streaks.
Texture: Fine to medium crystalline texture typical of marble, with a smooth, polished finish that highlights its subtle veining.
Physical & Mechanical Properties
- Mohs Hardness : ~3–4 (calcite-based marble)
- Compressive Strength : ~80–120 MPa
- Flexural Strength : ~10–15 MPa
- Water Absorption : ~0.3–0.5% by weight
- Density / Specific Gravity : ~2.6–2.7 g/cm³
Chemical & Mineral Composition (% by weight)
- CaCO₃ (Calcite) : ~90–95%
- MgCO₃ (Dolomite) : ~2–5%
- SiO₂ (Quartz) : <1%
- Fe₂O₃ and others : Trace amounts
Primarily composed of calcite, with minor dolomite and trace minerals contributing to coloration and pattern.
Applications & Usage
Interiors:
- Flooring, wall cladding, feature walls, and countertops
- Bathroom vanities, fireplaces, and decorative panels
Commercial & Residential:
- Lobby floors, hotel interiors, restaurants, and upscale residences
Best used in areas with moderate traffic due to marble’s relative softness compared to granite or quartzite.
Cutting Sizes & Formats
Slabs: Typically available in 2 cm and 3 cm thicknesses
Sizes range around 250–320 cm (length) × 150–200 cm (width) depending on block size
Tiles: Standard sizes like 30×30 cm, 60×60 cm, 60×120 cm are common, with custom cuts available.
Surface Finish Options
Polished: High gloss finish that enhances color depth and vein contrast.
Honed: Matte, smooth finish for a more subtle and contemporary look.
Leathered: Slightly textured surface with a soft sheen, offering slip resistance.
Brushed: Textured finish suitable for flooring with enhanced grip.
Maintenance & Care
Sealing: Recommended to protect against stains and water absorption, especially in wet areas.
Cleaning: Use pH-neutral cleaners designed for natural stone. Avoid acidic or abrasive cleaners that may etch or dull the surface.
Durability: Moderate hardness; scratches and etching possible with harsh use. Regular maintenance will prolong appearance and life.
