Verde Serpentino Marble

Verde Serpentino Marble

Description:
Verde Serpentino Marble is a luxurious and striking marble primarily sourced from quarries in Chiesa in Valmalenco and Torre di Santa Maria within the Provincia di Sondrio, Lombardia region of Italy. This marble is renowned for its rich, dark green color enriched with lighter veining patterns, giving it a unique serpentine appearance.

Physical and Mechanical Properties:

• Water Absorption: 0.30% by weight
• Density: 2795 kg/m³
• Flexural Strength: 61.5 MPa
• Compressive Strength: 223.0 - 242.0 MPa
• Hardness: Typically, the Mohs hardness is around 3-5 for serpentinite marble.
• Porosity: Generally low, enhancing its durability and resistance to weathering.
• Slip Resistance: Moderate when polished, higher resistance when honed or flamed for non-slip surfaces.

Chemical and Mineral Compositions (% by weight):

• Magnesium Silicate (Mg2SiO4): A major component, contributing to the characteristic green color.
• Silicates and Oxides: Present in varying proportions, often with trace elements enhancing its unique appearance.
• Iron Oxides: Minor quantities that can contribute to veining and color variations.

Applications and Usage:

1. Interior Uses:

• Flooring
• Wall cladding
• Countertops and vanity tops
• Staircases
• Fireplace surrounds

1. Exterior Uses:

• Facades
• Pool and fountain surrounds, though less common due to susceptibility to weather conditions.

1. Art and Sculptures:

• Often used for decorative pieces due to its aesthetic appeal.

Maintenance:

• Regular cleaning with pH-neutral cleaners to prevent etching.
• Sealing recommended to enhance stain resistance.
• Avoid acidic or abrasive cleaners.

Cutting Sizes (in cm):

• Standard tile sizes: 30x30, 30x60, 60x60
• Slab thickness: Typically 2 cm, 3 cm for custom applications.
• Custom sizes available for specific project requirements.

Surface Finish Options:

• Polished: High gloss finish that enhances the green color and veining.
• Honed: Matte finish for a natural look and increased slip resistance.
• Brushed: Textured finish that provides a rustic appearance.
• Flamed: Rough surface improving slip resistance, primarily used for outdoor applications.

Verde Serpentino Marble, with its rich historical context and superior aesthetic characteristics, remains a popular choice for luxury residential and commercial projects around the world. Its unique blend of colors and natural beauty makes it an exceptional material for those looking to add elegance and durability to their spaces.
