Verde Malenco Marble is a distinctive and visually compelling type of marble, known for its deep green coloration interspersed with black hues and light green stains. Quarried in the Val Malenco area of the Lombardy Region in the Raethian Alps of Italy, near the Swiss border, this marble is noted for its unique appearance due to its origin in serpentinite formations.

Physical and Mechanical Properties

1. Water Absorption:

• Typically low, indicating good resistance to water penetration.

2. Density:

• Approximately 2850 kg/m³, indicating a very dense and compact stone.

3. Flexural Strength:

• Generally high, providing good resistance to bending and impacts.

4. Compressive Strength:

• Usually significant, making it suitable for load-bearing applications.

5. Hardness:

• Moderately high, allowing it to resist scratches and wear relatively well.

6. Porosity:

• Low porosity is common, which enhances its durability and reduces water absorption.

7. Slip Resistance:

• Dependent on finish; polished surfaces might be less slip-resistant compared to honed or textured finishes.

Chemical and Mineral Compositions (% by weight)

• Primary Composition:

• Serpentine Minerals: This is largely responsible for its green color. The exact percentage can vary, typically making up the majority of the stone.

• Secondary Components:

• Lesser amounts of other minerals such as talc, chlorite, diopside, and calcite may be present.

Usage

• Interior Applications:

• Flooring, wall cladding, countertops, and decorative elements due to its striking appearance.

• Exterior Applications:

• Can be used for facades and outdoor applications, though it may require additional treatments to enhance weather resistance.

Maintenance

• Regular Cleaning:

• Use pH-neutral cleaners to avoid damaging the surface.

• Sealing:

• Periodic sealing is recommended to maintain its appearance and protect against staining.

• Avoidance of Acidic Substances:

• Acidic cleaners can etch and damage the surface, so they should be avoided.

Cutting Sizes (cm)

• Customizable according to project needs, but typical standard tile sizes might include:
• 30x30 cm
• 60x60 cm
• Slabs can be cut to larger sizes based on veining patterns and block size.

Available Common Surface Finish Options

1. Polished:

• Provides a glossy and reflective surface that highlights the color and veining.

2. Honed:

• Offers a matte finish with a smooth texture, ideal for flooring to reduce slipperiness.

3. Brushed or Antiqued:

• Creates a textured surface that is less slippery and has a rustic appearance.

4. Sandblasted:

• A rough-textured finish, often used for exterior paving due to its slip-resistant properties.

Verde Malenco Marble, with its elegant hues and resilience, is a superb choice for both functional and decorative architectural elements. It combines the natural beauty of marble with the unique characteristics of serpentinite, making it a versatile material with broad aesthetic and practical applications.
