Crna Kricka Marble is a striking and unique natural stone that is quarried in Kričke, located in the Drniš and Split regions of Croatia. This marble is known for its rich, dark caramel-brown color, which is beautifully complemented by dark beige hues. It is further accentuated by rusty-golden yellow and white streaks, making it an attractive choice for a variety of design applications.

Physical and Mechanical Properties

• Water Absorption: 0.5%
• Density: 2690 kg/m³
• Flexural Strength: 9.8 MPa
• Compressive Strength: 117.0 MPa
• Hardness: Generally assessed on the Mohs scale for marble, typically around 3-4.
• Porosity: Low due to its relatively low water absorption rate.
• Slip Resistance: Can vary based on the finish, with honed or flamed surfaces providing better resistance compared to polished finishes.

Chemical and Mineral Composition (Approximately % by weight)

• Calcite (CaCO3): Dominant mineral, typically around 90-95%
• Dolomite (CaMg(CO3)2): 0-5%
• Quartz (SiO2): Trace amounts, typically less than 2%
• Iron Oxides (Fe2O3): Trace amounts, contributing to the rusty-golden streaks
• Other Minerals: May include small percentages of other carbonate minerals and impurities

Usage

• Interior Flooring: Ideal for hallways, living rooms, and other high-traffic areas due to its durability and distinctive look.
• Wall Cladding: Offers an elegant and sophisticated finish to both residential and commercial spaces.
• Countertops: Used in kitchens and bathrooms for its aesthetic appeal and durability.
• Fireplaces: Perfect for creating luxurious focal points in living spaces.
• Staircases: Adds elegance and a touch of sophistication to stairwells.

Maintenance

• Regular Cleaning: Use pH-neutral cleaners and a soft cloth to maintain shine and prevent scratches.
• Sealing: Regular sealing is recommended, especially in high-contact areas, to protect against staining.
• Avoid Acidic Solutions: Cleaners that contain acid can etch the marble surface, so it is best to avoid them.

Cutting Sizes

• Slabs: Commonly available in various thicknesses, typically 2 cm or 3 cm.
• Tiles: Custom sizes are available, but common dimensions include 30x30 cm, 30x60 cm, 60x60 cm, and larger custom sizes based on project requirements.

Surface Finishes

• Polished: High-gloss finish that enhances color and veining, suitable for interior use.
• Honed: A matte finish providing a smooth texture, suitable for floors and areas requiring slip resistance.
• Brushed: Gives a slightly textured appearance, enhancing slip resistance while maintaining aesthetic appeal.
• Flamed: Offers a rough texture, making it ideal for outdoor use where slip resistance is essential.

Crna Kricka Marble is a versatile material favored for its beauty and strength, making it suitable for a range of architectural and decorative applications. Its unique coloration and patterning provide both contemporary and classic appeal, ensuring it stands out as a premium choice for discerning projects.
