• Bold black and dark gray grains or streaks

Pattern:

• Flowing and layered vein structure with irregular, organic movement
• Medium to coarse-grain texture
• Dynamic and earthy, with a warm, expressive aesthetic

Texture:

• Coarse crystalline structure
• Natural shimmer from quartz and feldspar grains

Physical and Mechanical Properties

• Bulk Density : 2.62 – 2.70 g/cm³
• Water Absorption : 0.20 – 0.35 % by weight
• Porosity : 0.3 – 0.6 %
• Compressive Strength : 150 – 180 MPa
• Flexural Strength : 13 – 18 MPa
• Abrasion Resistance : < 23 mm (Excellent for high-traffic areas)
• Mohs Hardness : 6 – 7
• Slip Resistance (R Rating) : R10 – R12 (depending on finish)

Test values may vary slightly by quarry batch; certified lab testing recommended for project-specific needs.

Chemical Composition (% by weight)

• SiO₂ (Silica) : 65 – 75%
• Al₂O₃ (Alumina) : 10 – 15%
• K₂O + Na₂O (Alkalis) : 4 – 7%
• Fe₂O₃ (Iron Oxide) : 2 – 4%
• CaO + MgO : <2%
• TiO₂, MnO, P₂O₅, etc. : <1% (trace elements)

Mineral Composition (% by weight)

• Quartz : 30 – 35%
• Feldspar : 50 – 55%
• Biotite & Hornblende : 5 – 10%
• Accessory Minerals : <5%

Surface Finish Options

• Polished – Enhances depth of color and reflection; most common
• Honed – Smooth matte finish; subtle elegance
• Leathered – Textured, slightly matte surface; slip-resistant and stylish
• Flamed – Rough, high-friction surface for exterior applications
• Bush-Hammered – Dimpled texture for maximum slip resistance
