Rosa de Porto Marble is a natural pink-colored marble quarried in the regions of Estremoz, Vila Viçosa, and Évora in Portugal. This marble is highly valued for its authentic pink tones and distinctive patterns, which can display light veins ranging from rose to greyish or orangey hues.

Physical and Mechanical Properties

• Water Absorption:0.07% to 0.10% by weight

• Density:Approximately 2718 kg/m³

• Flexural Strength:Ranges from 18.2 to 23.8 MPa

• Compressive Strength:Ranges from 70.2 to 95.2 MPa

• Hardness:Relative hardness consistent with common marble types (typically around 3 on the Mohs scale)

• Porosity:Low porosity, contributing to its durability and stain resistance

• Slip Resistance:Dependent on finish, but generally moderate to good in honed finishes

Chemical and Mineral Composition

• Calcium Carbonate (CaCO₃):Predominantly constitutes the marble with slight variations due to impurities

• Silicates and Other Impurities:Trace amounts can include clay, micas, or quartz, contributing to the veining and color variations

• Iron Oxides:Trace amounts may slightly alter the coloring, providing unique tone variations

Usage

• Interior Applications:Widely used in flooring, wall cladding, bathroom vanities, and countertops. Its unique patterns make it a favorite for decorative interior projects.

• Exterior Applications:Suitable for facades, although care should be taken due to potential weathering effects typical of natural stones.

• Sculptural and Artistic Uses:Due to its beautiful hues, it is often chosen for sculptures and artistic installations.

Maintenance

• Regular Cleaning:Use a soft cloth with a pH-neutral cleaner designed specifically for marble to prevent dulling.

• Sealing:Periodic sealing is recommended to maintain its resistance to stains and maintain its polished appearance.

• Avoiding Harsh Chemicals:Avoid acidic and abrasive cleaners which can etch the marble surface.

Cutting Sizes and Surface Finishes

Cutting Sizes:

Common sizes include tiles and slabs; tiles often range from 30x30 cm to larger formats like 60x60 cm or customized dimensions as required.

Surface Finishes:

• Polished: Enhances color and veining, creating a glossy, reflective surface.
• Honed: Provides a matte finish that is less reflective, popular for a more subdued appearance.
• Brushed: Provides a textured surface that highlights the stone's natural patterns and veins.
• Sandblasted: A rougher finish, adding slip resistance, suitable for certain exterior applications.

Conclusion

Rosa de Porto Marble, with its captivating pink hues and versatile applications, remains an elegant choice for both modern and traditional design projects. Its durability, combined with its aesthetic appeal, provides a luxurious option for various architectural and decorative uses. Proper maintenance ensures its lasting beauty, making it a timeless addition to any space.
