Karnis Special Marble is a brecciated marble variety extracted from the region of Karnazeika in Argolis, Peloponnese, Greece. It is renowned for its luxurious appearance characterized by angular fragments, giving it a distinctive mosaic-like appearance. The color palette includes dark tones of beige, ivory, soft brown, and light grey, making it a versatile choice for various design applications.

Physical and Mechanical Properties:

• Water Absorption: 1.7%
• Density: 2690 kg/m³
• Flexural Strength: 13.9 MPa
• Compressive Strength: 147.0 MPa
• Hardness: Generally around 3-4 on the Mohs scale (typical for marble)
• Porosity: Low to medium; specific percentage typically provided by quarry reports
• Slip Resistance: Depending on finish, but polished surfaces may generally have lower slip resistance

Chemical and Mineral Compositions (% by weight):

• Calcium Carbonate (CaCO3): Predominantly >90%
• Silica (SiO2): Minor amounts
• Aluminum Oxide (Al2O3): Trace elements
• Iron Oxide (Fe2O3): Imparts the brown tonalities, minor presence
• Magnesium Carbonate (MgCO3): May be present in varying quantities

Usage:

• Architectural applications: ideal for high-end residential and commercial projects.
• Interior use: floors, walls, countertops, and backsplashes.
• Suitable for customized furniture tops like tables or decorative elements.
• Exterior use is possible but considered carefully due to potential weathering.

Maintenance:

• Cleaning: Use a pH-neutral, non-abrasive cleaner specifically designed for natural stone.
• Sealing: Recommended to maintain the stone's appearance and protect from stains.
• Routine Maintenance: Regular dusting and immediate clean-up of spills prevent surface staining.

Standard Cutting Sizes (in cm):

• Tiles: Commonly available in sizes like 30x30, 30x60, and 60x60 cm.
• Slabs: Typically about 2-3 cm in thickness, dimensions vary based on quarry yield.
• Custom Sizes: Available upon request depending on project requirements.

Surface Finish Options:

• Polished: Offers a high-gloss finish that enhances color and veining.
• Honed: Provides a smooth, matte finish suitable for non-slip areas.
• Brushed/Leathered: Offers a textured finish that adds depth without high sheen.
• Acid-Washed: Uses a chemical process to create an antiqued appearance.
• Sandblasted: Provides a rougher surface for higher slip resistance, ideal for exteriors.

Karnis Special Marble, with its distinct appearance and robust properties, remains a popular choice for designers and architects looking to infuse elegance and durability into their projects. Its maintenance routine and varied finishes allow for versatile applications both indoors and outdoors.
