Rosa Corallo Marble

Rosa Corallo Marble is a classic and esteemed red marble originating from the Verona region in Veneto, Italy. This distinctive natural stone features a warm reddish to terracotta background interspersed with lighter calcite fossils, subtle white veins, and natural tonal variations. Its enduring beauty and historical significance make it a sought-after choice for both traditional and modern architectural applications.

Physical and Mechanical Properties:

• Water Absorption: 0.19%
• Density: 2690 kg/m³
• Flexural Strength: 9.8 MPa
• Compressive Strength: 150.0 - 160.0 MPa
• Hardness: Generally rated on the Mohs scale for marble, between 3 and 4.
• Porosity: Low, contributing to the stone's density and durability.
• Slip Resistance: This can vary based on the finish of the marble but generally requires treatment to avoid slipperiness when wet.

Chemical and Mineral Compositions (Approximate % by weight):

• Calcite (CaCO₃): Major component, usually around 90-95%.
• Dolomite (CaMg(CO₃)₂): Can be present in minor amounts.
• Quartz, Mica, and Iron Oxides: Trace elements contribute to colors and patterns.
• Silica (SiO₂): Small percentages, rarely above 2%.

Applications and Usage:

• Interior Flooring and Wall Cladding: Preferred for its aesthetic appeal in residential and commercial projects.
• Countertops: Offers a striking appearance for kitchens and bathrooms.
• Fireplace Surrounds: Adds warmth and elegance to living spaces.
• Monumental and Sculptural Uses: Valued for its workability and historical appeal.

Maintenance:

• Sealing: Requires regular sealing to protect against stains and moisture.
• Cleaning: Use pH-neutral cleaners to maintain the stone’s natural shine, avoid harsh chemicals that can etch or dull the surface.

Cutting Sizes (Commonly Available):

• Tiles: Can range from small (e.g., 30x30 cm) to larger formats (e.g., 60x60 cm or 120x60 cm) depending on project requirements.
• Slabs: Typically cut into thicknesses of 2 cm and 3 cm for various applications.

Surface Finish Options:

• Polished: Offers a high-gloss finish, enhancing the marble's natural colors and veining.
• Honed: Provides a matte, non-glossy surface, ideal for areas where slip resistance is important.
• Brushed/Antiqued: A textured finish that gives a rustic look while enhancing slip resistance.
• Sandblasted: A rougher texture suitable for outdoor or industrial applications.

Rosa Corallo Marble's enduring charm makes it an ideal material for a wide array of architectural and decorative applications. Its warm hues and classic appeal ensure it remains a favorite in design projects worldwide.
