Testing
- Water Absorption:
- 0.09 % by wt
- Density:
- 2680 kg/m3
- Flexural Strength:
- 16.95 MPa
- Compressive Strength:
- 78.50 MPa
- Stone texture:
- a refined natural stone characterized by a soft light-to-medium grey base, often shifting between silvery grey and slightly bluish or warm smoky grey tones, depending on the block. Its appearance is distinguished by elegant, linear “wood-grain” style veining in darker grey, white, and occasional faint beige or brown undertones, creating a structured, flowing pattern that resembles fossilized wood and gives the stone a sophisticated, architectural character. The overall look is calm yet expressive, with a subtle striped or layered movement rather than chaotic veining, making it highly desirable for contemporary and classic designs. In terms of texture and structure, it is a fine- to medium-crystalline metamorphic marble composed mainly of calcite, with a dense, tightly interlocked crystalline structure formed under natural heat and pressure; this gives it good strength, moderate water absorption, and a smooth, polishable surface suitable for both interior and exterior applications, especially where a durable yet elegant grey stone is required
Description
Nestos Grey Marble is a distinctive natural stone revered for its elegant and timeless appearance. Quarried in Kehrokambos, Kavala, Greece, this marble is renowned for its soft light-to-medium grey base, which can range from silvery grey to slightly bluish or warm smoky grey hues. Its surface features a structured, flowing pattern created by linear "wood-grain" style veining in darker grey, white, and occasional faint beige or brown undertones. This veining gives the marble a sophisticated, architectural character reminiscent of fossilized wood.
Physical and Mechanical Properties:
- Water Absorption: 0.09% by weight
- Density: 2680 kg/m³
- Flexural Strength: 16.95 MPa
- Compressive Strength: 78.50 MPa
- Hardness: Typically assessed with the Mohs scale, marble generally falls around 3 to 4, signifying a moderate level of hardness.
- Porosity: Low due to its dense crystalline structure, contributing to its durability.
- Slip Resistance: Can vary based on surface finish; polished surfaces are less slip-resistant than honed or textured finishes.
Chemical and Mineral Compositions:
- Calcite (CaCO₃): Dominant mineral, typically over 90% by weight, providing the marble’s primary crystalline structure.
- Dolomite: May be present in trace amounts, slightly altering color and texture.
- Quartz and Other Silicates: Present in minor amounts, contributing to the nuances in veining.
- Trace Minerals: Can include iron oxides, which add to the beige or brown undertones observed.
Usage:
- Interior Applications: Ideal for flooring, wall cladding, countertops, vanities, fireplaces, and decorative features.
- Exterior Applications: Suitable for facades, columns, and other architectural details due to its durability and resistance to weathering.
- Contemporary and Classic Designs: Its calm yet expressive appearance fits both modern and traditional aesthetics.
Maintenance:
- Regular Cleaning: Requires regular dusting and wiping with a damp cloth or a mild stone cleaner to maintain its finish.
- Sealing: Periodic sealing is recommended to protect against stains and enhance longevity.
- Avoiding Acidic Cleaners: As a calcite-based stone, it is susceptible to etching and should not be cleaned with acidic or abrasive cleaners.
Cutting Sizes (in centimeters):
- Commonly available in large slabs, typically ranging in sizes from 2 cm to 3 cm thickness.
- Tiles can be customized, with popular sizes including 30x30, 40x40, 60x60, and larger formats depending on project requirements.
Surface Finish Options:
- Polished: Offers a high-gloss finish that enhances color depth and veining, ideal for indoor use.
- Honed: Provides a smooth, matte finish that offers enhanced slip resistance and is preferable for floors and high-traffic areas.
- Brushed/Antiqued: Adds texture for a more rustic or aged appearance.
- Sandblasted: Provides a rougher, textured finish that enhances slip resistance, suitable for outdoor uses.
Nestos Grey Marble’s unique combination of aesthetics and technical qualities makes it highly desirable for architects and designers seeking an elegant grey stone that balances beauty with durability.
