Bianco di Apricena is a type of stone quarried in Apricena, Provincia di Foggia, Puglia, Italy. Although geologically classified as a limestone, it is commonly referred to as marble in the international stone market due to its appearance and finish. It features a light creamy ivory-white color with subtle veining and occasional beige tones. Below is a detailed description and listing of its properties, compositions, and uses:

Physical and Mechanical Properties

• Water Absorption:0.03% by volume

• Density:2720 kg/m³

• Flexural Strength:Range of 14.4 - 18.1 MPa

• Compressive Strength:Range of 148.6 - 175.1 MPa

• Hardness:Typically measured on the Mohs scale, Bianco di Apricena would have a hardness rating of about 3-4, typical for limestone and softer than true marble.

• Porosity:Generally low due to its dense structure.

• Slip Resistance:Varies based on the finish, with honed and polished surfaces having lower slip resistance compared to bush-hammered or sandblasted finishes.

Chemical and Mineral Compositions

• Calcite: Approximately 95-97%
• Quartz: Minor content, usually less than 2%
• Other Minerals: Trace amounts of clay and silt.

Usage

Bianco di Apricena is versatile and can be used for various applications including:

• Interior and Exterior Flooring
• Wall Cladding
• Staircases
• Countertops
• Bathroom Vanities
• Fireplaces
• Architectural Details

Maintenance

• Regular Cleaning: Use pH-neutral cleansers to avoid damaging the stone.
• Sealing: Periodic sealing is recommended to protect against staining and moisture.
• Avoid Acidic Substances: Clean spills immediately to prevent etching.

Cutting Sizes

Bianco di Apricena is available in a variety of sizes, typically offered in tiles and slabs. Common tile sizes include:

• 30 x 30 cm
• 30 x 60 cm
• 60 x 60 cm
• Custom sizes are possible based on the project requirements.

Available Surface Finish Options

• Polished: High gloss finish, enhances the color and veining.

• Honed: Smooth, matte finish, less reflective.

• Brushed: Gives a slightly textured finish, offers more slip resistance.

• Sandblasted: Rough texture, highly slip-resistant, often used for outdoor installations.

• Bush-Hammered: Heavily textured, provides a rugged appearance and excellent slip resistance.

In summary, Bianco di Apricena is a durable and aesthetically pleasing stone suitable for various architecture and design projects. Its classic look and physical properties make it a popular choice in both residential and commercial applications. Proper maintenance and finish selection can maximize its longevity and beauty.
