Verde Alpi Chiaro Marble Overview:

Verde Alpi Chiaro Marble is a stunning natural stone primarily quarried in Chatillon, Provincia di Aosta, Valle d'Aosta, Italy. Renowned for its light green coloration complemented by white and darker green veining, this marble brings a touch of elegance and natural beauty to various architectural and interior design projects.

Physical and Mechanical Properties:

• Water Absorption: 0.59%
• Density: 2745 - 2900 kg/m³
• Flexural Strength: 20.1 MPa
• Compressive Strength: 141.0 - 188.9 MPa
• Hardness: Typically ranges around 3-4 on the Mohs scale, indicating moderate hardness.
• Porosity: Low porosity makes it relatively resistant to staining but not entirely impervious.
• Slip Resistance: Generally moderate; slip resistance can be enhanced with specific surface finishes.

Chemical and Mineral Compositions (approximate % by weight):

• Calcium Carbonate (CaCO3): Approximately 90-98%
• Silica (SiO2): 2-5%
• Other Minerals/Impurities: Traces of minerals such as iron oxides (give darker veining) and possibly magnesium depending on the specific quarry source.

Uses and Applications:

• Residential: Flooring, wall cladding, countertops, vanity tops, fireplaces.
• Commercial: Interior walls, floors, reception desks, conference tables.
• Decorative: Stairs, columns, bathroom designs, decorative items like vases and sculptures.

Maintenance:

• Regular Cleaning: Use pH-neutral cleaners and avoid acidic or abrasive substances to prevent etching and damage.
• Sealing: Periodic sealing is recommended to enhance stain resistance and longevity.
• Polishing: Occasional polishing may be required to maintain its natural sheen, especially in high-traffic areas.

Cutting Sizes (common dimensions in cm):

• Tiles: Common tile sizes include 30x30, 30x60, 60x60 cm.
• Slabs: Available in varying thicknesses, commonly 2 cm and 3 cm.

Surface Finish Options:

• Polished: Enhances the colors and veining, offering a glossy appearance.
• Honed: Provides a matte finish, reducing glare and is less slippery.
• Brushed: Offers a textured feel and a more rustic look.
• Tumbled: Creates an aged appearance with rounded edges.

Conclusion:

Verde Alpi Chiaro Marble, with its aesthetically pleasing light green shade and unique veining patterns, is a versatile material suitable for various high-end applications. Its physical and mechanical properties make it durable enough for both residential and commercial use, though like all marble, it requires some degree of regular maintenance to preserve its beauty over time. Its wide range of finishes and available sizes provide flexibility in design and application, making it a favored choice for architects and interior designers alike.
