Crevola di Ossola Venato Marble is a stunning dolomitic marble known for its semi-white background adorned with flowing diagonal streaks of grey and beige. These watermark-like patterns evoke the dramatic appearance of a storm, making it a unique and elegant choice for various architectural applications. The marble is quarried in Crevoladossola, near Domodossola, in the Val d'Ossola area of the Province of Verbano-Cusio-Ossola, Piemonte, Italy.

Physical and Mechanical Properties:

• Color: Semi-white with grey and beige streaks
• Water Absorption: 0.15% by weight
• Density: 2810 kg/m³
• Flexural Strength: 29.6 MPa
• Compressive Strength: 165.0 - 167.0 MPa
• Hardness: Similar to other dolomitic marbles; typically moderate, suitable for indoor applications
• Porosity: Low, contributing to its durability
• Slip Resistance: Depending on the finish, generally moderate; polished finishes may be less slip-resistant than honed or textured finishes

Chemical and Mineral Composition (percent by weight):

• Calcium Carbonate (CaCO₃): Predominantly high, contributing to its dolomitic nature
• Magnesium Carbonate (MgCO₃): Present due to the dolomitic composition
• Silica (SiO₂): Typically present in small amounts
• Other Minerals/Impurities: Trace amounts of minerals that give a unique coloration and veining patterns

Usage:

• Interior Applications: Suitable for flooring, wall cladding, countertops, staircases, and bathroom vanities.
• Exterior Applications: Limited; mainly used in areas with minimal exposure to harsh weather conditions due to its moderate resistance to weathering.

Maintenance:

• Cleaning: Regular cleaning with pH-neutral cleaners is recommended.
• Sealing: Periodic sealing is advised to protect against staining, especially in high-use areas like kitchens and bathrooms.
• Polishing: Can be polished to retain its gloss and enhance its aesthetic appeal.

Cutting Sizes (common cm dimensions):

• Tiles: Commonly available in 30x30, 30x60, 60x60 cm
• Slabs: Typically available in custom sizes to accommodate specific project requirements

Available Surface Finish Options:

• Polished: Achieves a glossy, reflective surface that enhances the color and veining
• Honed: Provides a smooth, matte finish that is less slippery
• Brushed: Adds texture to the surface, enhancing slip resistance
• Antiqued: Offers a rustic, aged appearance with more pronounced texture

Due to its unique appearance and refined characteristics, Crevola di Ossola Venato Marble is a favorite among designers and architects for creating luxurious and sophisticated spaces. Its maintenance and adaptability to various finishes make it a versatile choice for both traditional and contemporary designs.
