Phoenix Gray Marble

Phoenix Gray is a marble quarried in Iran, featuring a soft, muted grey background with subtle warm beige and taupe undertones. Its elegant, neutral color palette is complemented by delicate tonal variations, creating a natural and sophisticated appearance. Irregular white and light grey veins contrast gently with the base, while distinctive dark grey to black fossil-like formations add character and visual depth.

Texture & Structure

Features a fine-grained, predominantly compact crystalline marble structure with scattered bioclastic inclusions. The surface displays irregular linear veining, web-like patterns, and distinctive organic formations resembling leaves or feathers. Small clustered circular micro-fossils and darker fossil impressions are distributed throughout the stone, giving it a characteristic fossil-bearing appearance. Natural variations in fossil density, veining, and mineral distribution occur between slabs.

Technical Characteristics & Test Results

The following values are indicative reference ranges for comparable Iranian grey marbles, not certified test results for Phoenix Gray. Actual properties should be confirmed through laboratory testing.

• Apparent Density: 2,650–2,700 kg/m³

• Water Absorption: 0.20–0.35% by weight

• Compressive Strength: 85–115 MPa

• Flexural Strength: 12–16 MPa

• Mohs Hardness: 3–4

• Porosity: Low to moderate

• Abrasion Resistance: Moderate, depending on mineral composition and surface finish

Chemical & Mineralogical Composition (% by Weight)

Indicative composition for calcitic fossil-bearing grey marble:

• Calcium Carbonate (CaCO₃): 85–95%

• Magnesium Carbonate (MgCO₃): 1–8%

• Silica (SiO₂): 1–5%

• Iron Oxides (Fe₂O₃): 0.1–1%

• Aluminium Oxide (Al₂O₃): 0.1–1%

• Other Mineral Components and Trace Elements: Balance

Typical mineral constituents may include:

• Calcite: 85–95%

• Dolomite: 1–8%

• Quartz: 1–5%

• Clay Minerals, Mica and Iron-bearing Minerals: Minor amounts

• Fossil Fragments and Organic-derived Inclusions: Variable

These are indicative estimates, not a verified chemical or mineralogical analysis.

Usage & Applications

Suitable for a wide range of residential and commercial architectural applications, including:

• Interior flooring and wall cladding

• Bathroom walls and vanity tops

• Kitchen countertops and backsplashes

• Feature walls and decorative panels

• Hotel lobbies and reception areas

• Staircases, risers and treads

• Fireplace surrounds

• Dining tables and furniture tops

• Decorative cut-to-size projects and bookmatched installations

Maintenance

• Seal the surface with a suitable penetrating stone sealer to reduce staining and moisture absorption.

• Clean regularly using a pH-neutral stone cleaner and a soft cloth or mop.

• Avoid acidic cleaners, vinegar, lemon juice and abrasive chemicals, as they can etch the calcite surface.

• Wipe spills promptly, particularly oils, coffee, wine and acidic liquids.

• Use protective pads under heavy or sharp objects to minimize scratching.

• Periodically inspect and renew the protective sealer as required.

Recommended Finishes: Polished, Honed, Leathered, Brushed and Sandblasted.
