Description
Thassos Marion Semi White Marble is a moderately fine crystalline marble quarried from Thassos Island in Kavala, East Makedonia, North-East Greece. It is renowned for its soft off-white to light creamy white base with subtle, very fine crystalline variations. Unlike bold-veined marbles, this stone offers a gentler, more muted white appearance, maintaining a classic, elegant aesthetic suitable for both traditional and contemporary spaces.
Physical and Mechanical Properties:
- Water Absorption: 0.17% by Weight
- Density: 2700 kg/m³
- Flexural Strength: 11.0 MPa
- Compressive Strength: 72.0 MPa
- Hardness: Generally measured using the Mohs scale, marble typically ranges between 3-4.
- Porosity: Low, contributing to its durability.
- Slip Resistance: Generally good slip resistance when surface finishes are applied appropriately, though specific slip resistance values may vary depending on the finish.
