Brilliant Gray Quartzite

Brilliant Gray Quartzite is a highly esteemed natural stone, renowned for its aesthetic sophistication and versatility. It is quarried in Brazil, displaying a distinguished palette of silver-gray, smoky charcoal, soft ash, and delicate white tones. The stone's surface is ornamented with dynamic linear veining, cloudy mineral shadings, and graphite accents, imbuing each slab with depth and a modern, architectural appeal. Its crystalline texture is medium to coarse-grained, typical of premium Brazilian quartzites. The stone's dense, compact structure and areas of natural translucency contribute to its unique visual character.

Physical and Mechanical Properties:

• Water Absorption: Typically low, around 0.2% to 0.34%, indicating minimal porosity.
• Density: Approximately 2.64 to 2.68 g/cm³.
• Flexural Strength: Ranges from 18 to 22 MPa, showcasing its robustness.
• Compressive Strength: Typically between 170 to 220 MPa.
• Hardness: Rated 7 on the Mohs scale, reflecting excellent scratch resistance.
• Porosity: Low, thanks to its dense structure.
• Slip Resistance: Varies with finish; a honed or textured finish provides good slip resistance making it suitable for floor applications.

Chemical and Mineral Composition (% by weight):

• Quartz: 85-95%, providing hardness and durability.
• Mica: 1-5%, contributing to the stone's sheen.
• Feldspar: 3-10%, influencing the stone's resilience.
• Other Minerals: Trace amounts, including iron oxides and graphite accents that influence color variation.

Usage:

• Interior Applications: Perfect for kitchen countertops, bathroom vanities, flooring, and wall cladding.
• Exterior Applications: Suitable for outdoor facades, patios, and landscaping.
• Commercial Spaces: Used in lobbies, restaurants, and hotels for its modern aesthetic and durability.

Maintenance:

• Cleaning: Gentle cleaning with mild soap and water. Avoid acidic or abrasive cleaners.
• Sealing: Recommend periodic sealing (annually) to enhance stain resistance and maintain surface integrity.
• Polishing: Not typically required, but occasional professional polishing can restore original luster.

Cutting Sizes (cm):

• Common slab sizes range from 120 cm x 220 cm to 160 cm x 300 cm.
• Custom sizes can be cut to fit specific project requirements.

Available Common Surface Finishes:

• Polished: High-gloss finish that highlights color and veining.
• Honed: Smooth, matte finish offering a softer appearance.
• Leathered: Textured finish with a subtle sheen, providing a tactile surface.
• Brushed: Enhances texture with a semi-smooth surface, giving a rustic look.
• Sawn: Rough surface, often used for pathways and exterior applications.

Brilliant Gray Quartzite’s unique blend of aesthetic appeal and practical properties makes it a sought-after material for both residential and commercial projects.
