Rosa Dante Granite

Rosa Dante Granite is a biotite granite distinguished by its warm pink to rose tones, often highlighted with subtle grey and white specks. Quarried near Porriño in the province of Pontevedra, Galicia, Spain, this granite is known for its aesthetic appeal due to its lively, multi-tonal appearance. Composed predominantly of feldspar with visible darker mineral crystals distributed throughout, it features a coarse to medium grain texture and an irregular fracture. These properties contribute to its suitability for both classic and contemporary architectural designs.

Physical and Mechanical Properties:

• Water Absorption: 0.3%
• Density: 2650 kg/m³
• Flexural Strength: 12.4 MPa
• Compressive Strength: 105.6 MPa
• Hardness: Generally high, typical of granitic stones, suitable for heavy-duty applications.
• Porosity: Low porosity contributes to its resistance to weathering and staining.
• Slip Resistance: Varies with finish, but generally moderate; polished surfaces are less resistant than honed or flamed finishes.

Chemical and Mineral Compositions (% by weight):

• Feldspar: Predominantly present, contributing largely to its color and texture.
• Quartz: Provides strength and contributes to the granite's hardness.
• Biotite: Imparts the darker mineral specks.
• Other minerals: May include small percentages of mica, amphibole, and other trace minerals.

Usage:

• Interior Applications: Countertops, bathroom vanities, flooring, staircases.
• Exterior Applications: Cladding, paving, outdoor sculptures, and monuments.
• Architectural Settings: Works well in both classic and contemporary styles, appreciated for its warm color palette and versatile texture.

Maintenance:

• Cleaning: Requires regular cleaning with non-abrasive products to maintain its appearance.
• Sealing: Periodic sealing recommended to protect against stains and moisture infiltration.

Cutting Sizes (cm):

• Available in a wide range of sizes to meet the specific requirements of different applications. Common fabrication dimensions can include tiles or slabs measuring 30x30, 40x40, 60x60, or custom sizes for larger applications.

Available Common Surface Finish Options:

• Polished: Highly reflective surface that highlights the stone's color and pattern. Not suitable for high-slip risk areas.
• Honed: Smooth, matte finish that enhances color while reducing reflectivity.
• Flamed: Rough texture that increases slip resistance, suitable for exterior applications.
• Bush-Hammered: Textured finish that provides excellent slip resistance and a rustic appearance.

Overall, Rosa Dante Granite is chosen for its combination of aesthetic qualities and durable properties, making it an ideal choice for a variety of architectural and design applications.
