Sao Tome Quartzite is a golden beige natural quartzite with a wavy flowing pattern and light cream shades, creating an elegant and timeless aesthetic. Quarried in Minas Gerais, Brazil, it is widely known for its high durability, resistance to weathering, and slip-resistant properties, making it ideal for both interior and exterior applications.

Texture & Pattern:

• Texture: Medium to fine-grained, naturally rough but can be refined with finishing.
• Pattern: Soft golden beige background with wavy movement, complemented by light cream shades, creating a warm and dynamic appearance.
• Porosity: Low, reducing water absorption and increasing longevity.
• Slip Resistance: Excellent, especially in natural split or brushed finishes, making it ideal for outdoor use.

Technical Properties (Test Results):

• Density: ~2.65 - 2.75 g/cm³
• Water Absorption: ≤ 0.5%
• Compressive Strength: ~140-165 MPa
• Flexural Strength: ~17-22 MPa
• Mohs Hardness: ~6.5-7.0 (Highly scratch-resistant)
• Thermal Resistance: Excellent, suitable for hot climates and direct sunlight exposure.
• Slip Resistance:

       Natural Split: High slip resistance (R11-R12)

       Brushed/Honed: Moderate slip resistance

Chemical Composition (% by Weight):

• Silica (SiO₂): ~88-94%
• Alumina (Al₂O₃): ~1-3%
• Iron Oxide (Fe₂O₃): ~1-3% (Gives the golden beige tones)
• Calcium Oxide (CaO): ~0.5-1.5%
• Magnesium Oxide (MgO): ~0.5-1.0%

Mineral Composition (% by Weight):

• Quartz: ~90-95% (Ensures high strength and weather resistance)
• Mica: ~2-4% (Gives a slight shimmer and enhances texture)
• Feldspar: ~2-5% (Adds durability and color variation)
• Iron Minerals: ~1-3% (Responsible for golden beige tones)

Applications & Usage:

• Indoor Flooring: Ideal for residential and commercial spaces due to its durability and aesthetic appeal.
• Outdoor Paving: Perfect for patios, pool decks, and walkways due to its non-slip properties.
• Wall Cladding: Adds warmth and natural beauty to facades and interiors.
• Pool Surrounds & Spas: Heat-resistant, making it comfortable to walk on even in hot climates.
• Countertops & Vanities: Durable and resistant to scratches and heat.
• Stair Treads & Risers: Strong and long-lasting with elegant patterns.

Maintenance & Care:

• Cleaning: Mild soap and water; avoid acidic cleaners.
• Sealing: Recommended for high-use or moisture-prone areas to enhance stain resistance.
• Repairs: Small chips or cracks can be repaired with quartzite epoxy.
• Regular Maintenance: Occasional resealing for maximum performance.
