Description
Royal Danby Marble is a highly regarded natural stone known for its clean white background accentuated by medium-intensity gray veining. It is quarried from the largest underground marble quarry in the world, located in Rutland County, Green Mountains, Vermont, USA.
Physical and Mechanical Properties:
- Water Absorption: 0.06% by weight
- Density: 2710 kg/m³
- Flexural Strength: 8.45 MPa
- Compressive Strength: 65.33 MPa
- Hardness: Moderately high (specific measurements can vary, typically assessed using the Mohs scale where it might range around 3-4)
- Porosity: Low - indicates a dense material, less susceptible to staining
- Slip Resistance: Generally low when polished but can be enhanced with textured finishes for better traction.
Chemical and Mineral Composition:
- Calcium Carbonate (CaCO3): Primary component, typically >90%
- Silica (SiO2): <3%
- Other minerals (such as albite, clay, or trace oxides): Varies, usually <5%
Usage Possibilities:
Interior Design:
- Flooring
- Wall cladding
- Countertops
- Backsplashes
- Fireplace surrounds
Exterior Applications:
- Facades
- Landscaping elements (e.g., benches, planters)
Specialty Projects:
- Artistic installations
- Sculptures
Maintenance:
- Regularly clean with pH-neutral cleaners to avoid etching.
- Seal periodically to protect against staining and scratching.
- Wipe up spills quickly, especially acidic substances like lemon juice or vinegar.
- Use coasters, mats, and trivets to protect the surface in kitchen settings.
Common Cutting Sizes (cm):
- Tiles: 30x30, 30x60, 60x60, custom sizes available
- Slabs: Typically vary in thickness around 2cm or 3cm; widths and lengths depend on specific quarry blocks
Available Surface Finish Options:
- Polished: High gloss finish enhances color and veining
- Honed: Smooth, matte finish suitable for a more understated look
- Brushed/Antiqued: Textured finish for a more rustic appearance
- Sandblasted: Offers a rough, textured surface with increased slip resistance
Royal Danby Marble is a versatile choice due to its aesthetic appeal and robust physical properties, making it a preferred option for both traditional and modern design applications. Proper maintenance ensures its longevity and maintains its pristine appearance.
Gray, muted veins (softer compared to Statuary Marble). Consistent medium veining pattern.
