Palissandro Antique Marble is a distinctive and visually appealing natural stone characterized by a mostly white background adorned with dense veining, which ranges in color from grey and golden to light brown. Quarried in Vietnam's Yen Bai Province, this marble is appreciated not only for its unique aesthetic qualities but also for its functional properties.

Physical and Mechanical Properties:

• Water Absorption:Typically low, generally around 0.2% to 0.4%, indicating it's relatively non-porous and less prone to staining.
• Density:Approximately 2.6 to 2.8 g/cm³, which is typical for marble, contributing to its durability.
• Flexural Strength:Ranges between 10 to 15 MPa, indicating good resistance to bending or breaking under pressure.
• Compressive Strength:Typically falls between 100 to 150 MPa, showcasing its ability to withstand substantial loads.
• Hardness:Mohs hardness of around 3 to 4, meaning it's susceptible to scratching by harder materials.
• Porosity:Generally low porosity, enhancing its stain resistance and longevity.
• Slip Resistance:Coefficient typically around 0.6 to 0.7 when dry, which can vary based on the surface finish; polished surfaces are more slippery compared to honed or textured finishes.

Chemical and Mineral Composition:

• Calcium Carbonate (CaCO₃):Predominantly around 90% to 95%, as it is the primary component of marble.
• Silica (SiO₂):Typically around 2% to 4%, contributing to the strength and integrity of the stone.
• Iron Oxides (Fe₂O₃):Approximately 1% to 2%, which can influence the coloration of the veins.
• Magnesium:Trace amounts; contributes to the color variations.
• Other Minerals:Small percentages of other minerals and compounds that contribute to its unique veining patterns.

Usage:

• Interior Flooring: Excellent for indoor flooring due to its elegance and durability.
• Wall Cladding: Suitable for both internal and external wall cladding.
• Countertops and Vanity Tops: Popular for use in kitchens and bathrooms.
• Decorative Features: Can be used in sculptures, pillars, and feature walls due to its distinctive appearance.
• Fireplace Surrounds: Adds a luxurious touch to interior spaces.

Maintenance:

• Regular sealing is recommended to maintain its resistance to staining and etching.
• Clean with pH-neutral cleaners; avoid acidic or abrasive cleaners to prevent damage.
• Regular maintenance to prevent scratch and wear over time.

Cutting Sizes:

• Commonly available in slabs that are 2 cm to 3 cm thick.
• Tile sizes generally available in 30 cm x 30 cm, 30 cm x 60 cm, or custom sizes based on project requirements.

Surface Finish Options:

• Polished: Provides a glossy finish that enhances the color and veining but is more prone to scratches and requires more maintenance.
• Honed: A matte finish that offers a more natural look and is less slippery, making it ideal for flooring.
• Brushed: Offers a textured surface that increases slip resistance, suitable for high-traffic areas.
• Antiqued: Gives a rugged, timeworn appearance, adding character and warmth to spaces.

Palissandro Antique Marble, with its stunning visual appeal and robust properties, is a versatile choice for architects and homeowners looking for a material that carries both beauty and durability. Proper maintenance will ensure its longevity and preserve its aesthetic attributes.
