Karnezeika Beige Marble is a distinctive brecciated marble from the Argolis region in the Peloponnese, Greece. Known for its warm, earthy palette, it features a unique mosaic-like appearance with angular fragments in beige, ivory, soft brown, and light grey tones. Here is a detailed description of its properties, composition, uses, maintenance, available cutting sizes, and surface finish options:

Physical and Mechanical Properties

• Water Absorption: 0.15 - 0.23% by weight
• Density: 2710 kg/m³
• Flexural Strength: 14.2 MPa
• Compressive Strength: 97.9 MPa
• Hardness: Generally measured by the Mohs scale; typical marble hardness ranges around 3-4.
• Porosity: Generally low due to its compact nature, contributing to its durability.
• Slip Resistance: Varies with finish; polished surfaces are less slip-resistant, whereas honed or textured finishes can improve slip resistance.

Chemical and Mineral Composition

• Calcium Carbonate (CaCO3): Predominantly composed of calcite (accounts for most of the marble).
• Silicates: Present in smaller quantities, influencing the color and pattern.
• Iron Oxides: Provide the range of earthy tones, contributing to the beige and brown hues.
• Trace Minerals: These can include quartz, mica, and other components adding to its color variety.

Usage

• Interior Applications: Ideal for flooring, wall cladding, countertops, and decorative features due to its aesthetic appeal.
• Exterior Applications: Sometimes used in exterior cladding and landscaping, although surface treatments are recommended to enhance durability and slip resistance.
• Artistic Elements: Used for sculptural elements and artistic installations due to its distinctive appearance.

Maintenance

• Regular Cleaning: Use a mild, pH-balanced cleaner to preserve its natural beauty and prevent etching.
• Sealing: Periodic sealing is recommended to protect against staining and moisture absorption.
• Avoid Acidic Substances: Acidic cleaners and spills can etch or stain the marble surface.

Cutting Sizes

Commonly available in a variety of sizes to suit different applications, including:

• Tiles: Typically cut into standard sizes such as 30x30 cm, 30x60 cm, and 60x60 cm.
• Slabs: Available in larger formats, often around 2 cm or 3 cm thickness, which can be customized based on project requirements.

Surface Finish Options

• Polished: Offers a high-gloss, luxurious finish that enhances the color and patterns.
• Honed: Provides a matte finish with a smooth surface, offering a more subdued, natural look.
• Brushed: Adds texture to the surface, improving slip resistance while maintaining visual appeal.
• Antiqued: Gives a weathered, rustic appearance, ideal for traditional or rustic designs.

Karnezeika Beige Marble’s combination of aesthetic charm and practical properties makes it a popular choice in both residential and commercial projects, offering versatility and an elegant visual impact across a range of applications.
