Bacurau Granite

Bacurau Granite, quarried in Brazil, is known for its striking aesthetic and versatile qualities. Its yellow to golden-beige color enhanced by warm brown and cream variations, coupled with light grey or darker speckling, creates a sophisticated and natural “golden granite” appearance. The medium-grained crystalline structure of Bacurau Granite, composed of quartz, feldspar, and mica, provides a robust durability and a polished finish that is slightly speckled.

Physical and Mechanical Properties

• Water Absorption: Generally low, typically around 0.25-0.45%, indicating good resistance to moisture-related issues.
• Density: Approximately 2,650 - 2,720 kg/m³, reflecting its substantial heft and strength.
• Flexural Strength: Typically around 12-15 MPa, which indicates good resistance to bending forces and suitability in structural applications.
• Compressive Strength: Ranges from 165-185 MPa, demonstrating its capacity to withstand high pressures.
• Hardness: Ranges around 6-7 on the Mohs scale, ensuring it can resist scratching and abrasion.
• Porosity: Low, less than 1%, contributes to its durability and ease of maintenance.
• Slip Resistance: Natural cleft finishes provide moderate slip resistance, suitable for both indoor and outdoor applications.

Chemical and Mineral Compositions

• Quartz: Approximately 30-35% by weight, contributing to its hardness and glossy finish.
• Feldspar: Around 40-50%, usually potassium feldspar, adding to its unique color and strength.
• Mica: Roughly 5-10%, providing slight sheen and additional color variations.
• Other Minerals: Traces of biotite, hornblende, and other accessory minerals.

Usage and Applications

• Interior Applications: Commonly used for countertops, flooring, and wall cladding in kitchens and bathrooms due to its aesthetic appeal and durability.
• Exterior Applications: Suitable for facades, paving, and landscaping because of its resistance to weathering.
• Commercial Spaces: Ideal for high-traffic areas like hotel lobbies and office buildings, providing elegance and lasting performance.

Maintenance

• Cleaning: Requires regular cleaning with mild detergents; avoid acidic or abrasive cleaners to maintain shine.
• Sealing: Recommended every 1-3 years to enhance stain resistance, depending on usage.
• Repair: Minor chips or scratches can be polished; deep damages may require professional restoration.

Cutting Sizes and Common Surface Finish Options

Cutting Sizes: Typically available in slabs of 2 cm or 3 cm thickness; custom sizes can be ordered based on project requirements.

Surface Finishes:

• Polished: Reflective, glossy finish enhancing the color and pattern.
• Honed: Smooth with a matte surface, less reflective.
• Flamed: A rougher texture offering good slip resistance, ideal for exterior use.
• Brushed: Slight texture with a worn, aged appearance.

Bacurau Granite, with its beautiful and durable characteristics, combined with a range of application possibilities and finish options, makes it an excellent choice for various architectural and design projects.
