Description
Mylonite Quartzite
Material: Natural Quartzite (Mylonite - a metamorphic rock formed by dynamic recrystallization)
Origin: Quarried in Sweden
Commercial Designation: Green Cloudy Veined Quartzite
Geological Classification: Mylonitic Quartzite
Visual & Aesthetic Description
Mylonite Quartzite is characterized by a dramatic and painterly aesthetic. The stone features a deep, rich forest green to emerald green base that serves as a canvas for complex, flowing patterns. The most distinctive feature is its cloudy, mist-like veining in shades of silver-grey, charcoal, and white, which swirl and drift organically across the surface. The veining is not linear but rather forms soft, amorphous, wave-like formations that create a sense of depth and fluid movement, resembling an abstract aerial landscape or a stormy sky. The contrast between the dark green background and the luminous grey veining is pronounced, giving the stone a bold, sophisticated, and almost mystical appearance.
Technical Specifications
A. Physical & Mechanical Properties:
- Water Absorption: 0.1% – 0.3% (by weight)
- Density: 2,700 – 2,800 kg/m³
- Compressive Strength: 200 – 220 MPa
- Flexural Strength: 17 – 23 MPa
- Hardness (Mohs Scale): 6 – 7
- Abrasion Resistance: Excellent
- Frost Resistance: Excellent; suitable for interior and exterior applications
- Thermal Shock Resistance: High
B. Chemical & Mineral Composition (% by weight):
- Silicon Dioxide (Quartz, SiO₂): 85 – 92%
- Feldspar (Plagioclase/Orthoclase): 5 – 10%
- Mica Group Minerals (e.g., Chlorite, Sericite): 3 – 8% (primary contributor to green coloration and sheen)
- Iron Oxides & Other Accessory Minerals: 1 – 3%
- Trace Elements (e.g., Chromium): < 1% (can enhance green tones)
C. Geological Note:
As a mylonite, this rock has undergone intense shearing and recrystallization under pressure, which aligns mineral grains and contributes to its distinctive foliated, flow-like texture.
Available Formats & Processing
A. Standard Cutting Sizes:
- Slabs: Common large-format sizes: 260x160 cm, 280x180 cm, 300x200 cm.
- Thickness: 2 cm, 3 cm.
- Tiles: Modular sizes such as 30x30 cm, 30x60 cm, 60x60 cm, 60x120 cm.
- Custom Cuts: Available for specific architectural elements.
B. Surface Finish Options:
- Polished (Highly Recommended): A high-gloss polish maximizes the depth, color saturation, and dramatic contrast of the veining, enhancing the stone's jewel-like quality.
- Honed: A smooth, matte finish that softens the color contrast and provides a more contemporary, understated look.
- Leathered/Brushed: A textured, low-sheen finish that highlights the stone's natural grain and adds a tactile dimension.
- Flamed: A rough, thermal finish for exterior, non-slip applications (may obscure some detail).
- Sandblasted: A uniformly textured, matte surface.
Applications, Usage & Maintenance
A. Primary Applications:
- Statement Interiors: Dramatic feature walls, waterfall kitchen islands, grand reception desks.
- High-Traffic Flooring: Durable and suitable for residential and commercial lobbies.
- Exterior Cladding: Building facades, exterior wall features (with appropriate finish).
- Luxury Surfaces: Kitchen countertops, bathroom vanities, bar tops.
B. Usage & Maintenance:
- Durability: Highly durable, scratch-resistant, and suitable for high-use areas.
- Sealing: While quartzite is less porous than marble, applying a high-quality impregnating sealer is recommended for countertops to prevent potential staining from oils or pigments.
- Care: Clean with a pH-neutral stone cleaner. Avoid harsh abrasive pads and acidic chemicals.
- General: Its hardness makes it resistant to etching from common household acids.
Summary:
Mylonite Quartzite from Sweden is a high-end metamorphic stone prized for its deep green base and dramatic, cloud-like silver and grey veining. Its exceptional durability, striking visual impact, and suitability for both interior and exterior use make it a premier choice for architectural and design projects seeking a material that combines natural artistry with robust performance.
