Stellato San Giacomo Granite Overview:

Stellato San Giacomo Granite is a striking natural stone quarried in Lombardia, Italy. Known for its fine-grained appearance, it features a golden beige to ivory cream base accented by a pattern of darker grains, creating a sophisticated and elegant look. This granite is often used in various interior and exterior applications due to its aesthetic appeal and robust physical properties.

Physical and Mechanical Properties:

• Water Absorption: 0.31%, indicating low porosity and resistance to moisture penetration.
• Density: 2665 kg/m³, which signifies a relatively dense stone, contributing to its durability.
• Flexural Strength: 13.6 MPa, showing moderate resistance to bending forces, making it suitable for different structural applications.
• Compressive Strength: 158.0 MPa, denoting its ability to withstand substantial weight and pressure without cracking or breaking.
• Hardness: Typically measures around 6-7 on the Mohs scale, reflecting its capability to resist scratching and abrasion.
• Porosity: Low, consistent with its water absorption properties, enhancing its durability and stain resistance.
• Slip Resistance: Generally good, especially when finishes like honed or flamed are applied, ensuring safe use in areas prone to moisture.

Chemical and Mineral Composition:

• Quartz: Approx. 30-40% by weight, contributing to its hardness and resistance to weathering.
• Feldspar: Approx. 40-50%, a major component affecting the stone's color and strength.
• Mica: Approx. 5-10%, adds to the stone's intricate pattern and slight shimmer.
• Minor Minerals: May include biotite and amphiboles, influencing the darker grain patterns.

Usage:

• Interior Applications: Ideal for countertops, flooring, backsplashes, wall cladding, and fireplaces due to its aesthetic appeal and ease of maintenance.
• Exterior Applications: Suitable for facades, terraces, and garden features given its durability and weather resistance.
• Commercial and Residential Projects: Frequently used in both settings for its versatility and classic appearance.

Maintenance:

• Regular cleaning with mild soap and water is recommended.
• Use sealants periodically to enhance stain resistance and maintain its polished look.
• Avoid abrasive cleaners that may dull the surface.

Cutting Sizes:

• Typically available in standard slab sizes, often ranging from 2 cm to 3 cm in thickness.
• Custom sizes may be cut to meet specific project requirements.

Available Surface Finish Options:

• Polished: Enhances the stone's natural color and luster, ideal for interior uses.
• Honed: Offers a less glossy finish, providing a more subdued look suitable for both interior and exterior applications.
• Flamed: Increases slip resistance, making it excellent for outdoor uses like patios and pool surrounds.
• Brushed: Provides a rustic texture with a slightly aged appearance, popular for certain design aesthetics.

Stellato San Giacomo Granite is a versatile and durable choice for a variety of architectural and design projects, offering a timeless elegance and long-lasting performance.
