Sao Tome White Quartzite is a snow-white natural quartzite with ice jade shades and darker grains that create a visually appealing pattern. Quarried in Minas Gerais, Brazil, this quartzite is widely used in interior and exterior applications, thanks to its high durability, low porosity, and slip-resistant surface.

Texture & Pattern:

• Texture: Fine to medium-grained with a naturally rough yet elegant feel.
• Pattern: Predominantly snow-white with soft ice jade hues and darker mineral grains, adding depth and sophistication.
• Porosity: Low, making it resistant to water absorption and stains.
• Slip Resistance: Excellent in natural split and textured finishes, making it ideal for wet areas.

Technical Properties (Test Results):

• Density: ~2.65 - 2.75 g/cm³
• Water Absorption: ≤ 0.5%
• Compressive Strength: ~150-170 MPa
• Flexural Strength: ~17-22 MPa
• Mohs Hardness: ~6.5-7.0 (Highly scratch-resistant)
• Thermal Resistance: Excellent, making it suitable for hot climates
• Slip Resistance:

       Natural Split: High slip resistance (R11-R12)

       Honed/Brushed: Moderate slip resistance

Chemical Composition (% by Weight):

• Silica (SiO₂): ~90-95%
• Alumina (Al₂O₃): ~1-3%
• Iron Oxide (Fe₂O₃): ~0.5-2% (Responsible for darker grains)
• 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 resistance)
• Mica: ~2-4% (Gives a slight shimmer and enhances texture)
• Feldspar: ~2-5% (Enhances durability and polishability)
• Iron Minerals: ~0.5-2% (Responsible for darker grains in the pattern)

Applications & Usage:

• Indoor Flooring: Ideal for residential and commercial spaces due to its strength and beauty.
• Outdoor Paving: Commonly used for patios, walkways, and pool decks due to its slip-resistant nature.
• Wall Cladding: Enhances the aesthetics of interior and exterior walls.
• Pool Decks & Spas: Heat-resistant and comfortable underfoot.
• Countertops & Vanities: Scratch and heat-resistant, making it suitable for kitchens and bathrooms.
• Stair Treads & Risers: Durable and visually appealing.

Maintenance & Care:

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