Blanco Macael B Marble

Blanco Macael B Marble is a premium natural marble extracted from the rich quarries in Macael, located in the Sierra de los Filabres in Almeria, Andalusia, Spain. It is renowned for its pristine white background that is elegantly accented with delicate soft grey veining. The marble's fine to medium grain texture ensures a smooth and consistent surface, making it highly desirable for various decorative finishes such as polished and honed.

Physical and Mechanical Properties:

• Water Absorption: 0.1 - 0.2%
• Density: 2720 Kg/m³
• Flexural Strength: 12.1 - 14.2 MPa
• Compressive Strength: 81.1 - 87.4 MPa
• Hardness: Typically rated around 3-4 on the Mohs scale
• Porosity: Low, contributing to its durability
• Slip Resistance: Depends on the finish; honed surfaces generally offer better slip resistance than polished ones.

Chemical and Mineral Compositions:

• Calcium Carbonate (CaCO₃): Typically over 90%
• Magnesium Carbonate (MgCO₃): Up to 5%
• Trace elements: Silica, iron, and other mineral impurities

Uses:

• Interior flooring
• Wall cladding
• Staircases
• Vanity tops
• Bathroom fittings
• Kitchen countertops
• Decorative elements such as columns, sculptures, and fireplace cladding

Maintenance:
To maintain its pristine appearance, regular cleaning with a soft cloth and pH-neutral cleaning solutions is recommended. Avoid harsh chemicals, abrasive materials, and acidic substances as they can damage the surface of the marble. Sealing the marble can help reduce its natural porosity and enhance its resistance to stains.

Common Surface Finish Options:

• Polished: High gloss finish that enhances the marble's natural luster and veining.
• Honed: Smooth and matte finish offering a more subtle and refined look with better slip resistance.
• Brushed: Provides a textured surface that adds character while maintaining a degree of slip resistance.
• Sandblasted: A rough finish that enhances grip and durability, suitable for outdoor applications.

Blanco Macael B Marble's combination of aesthetic appeal, durability, and versatility makes it a favored choice in luxury architectural and interior design projects worldwide.
