Yangtze White Granite – Technical and Aesthetic Overview

• Origin Quarry Location: China (commonly from regions near the Yangtze River basin)
• Stone Type: Igneous, intrusive granite

Appearance & Aesthetic Characteristics

• Color & Texture: Yangtze White Granite features a fine-grained white to light gray background peppered with small black and grey mineral flecks, giving it a clean "sesame" appearance—hence the nickname Sesame White.
• Pattern: Uniform and consistent. Ideal for large-scale projects where visual continuity is required. This pattern offers a modern, neutral aesthetic well-suited for both residential and commercial designs.
• Surface Texture: Natural grain is compact and dense, making it suitable for high-polish and textured finishes alike.

Chemical Composition (% by weight)

(Typical granite composition – actual may vary slightly by quarry batch)

SiO₂ (Silica) .... 68 – 75%

Al₂O₃ (Alumina) .... 12 – 15%

K₂O + Na₂O .... 3 – 5%

Fe₂O₃ .... 1 – 2%

CaO + MgO .... 1 – 3%

TiO₂, MnO, others .... <1%

Mineralogical Composition (% by weight)

• Quartz .... 30 – 35%
• Feldspar .... 45 – 55%
• Mica (Biotite, Muscovite) .... 5 – 10%
• Minor accessory minerals .... <5%

Applications

Yangtze White Granite is highly versatile and widely used for:

• Exterior cladding and façades
• Interior flooring and wall cladding
• Staircases, thresholds, and window sills
• Kitchen countertops and vanity tops
• Public paving and curbing
• Monuments and memorials

Its fine grain and durability make it suitable for high-traffic commercial spaces, urban infrastructure, and weather-exposed applications.

Surface Finish Options

• Polished .... High-gloss; enhances the stone’s natural color
• Honed .... Smooth matte; softens the appearance
• Flamed .... Textured, anti-slip surface for outdoor use
• Bush-hammered .... Heavily textured for rugged surfaces
• Sandblasted .... Fine texture for subtle non-slip surfaces
• Leathered .... Slightly undulating, soft-touch surface

Available Cutting Sizes (Typical Production) (cm)

• Tiles: 30×30, 60×60, 80×80, 60×120, Thickness: 1.5 / 2
• Slabs: 240×120 up to 300×180, Thickness: 2 / 3
• Cut-to-size: Per architectural specs
• Custom - Paving Stones / Cubes: 10×10×8, 15×15×10, etc.5 – 15

Maintenance and Care

• Routine Cleaning: Use mild detergent and water; avoid acidic cleaners.
• Sealing: Not always required due to low porosity, but sealing enhances stain resistance, especially for kitchen or commercial use.
• Durability: Resistant to UV, frost, abrasion, and chemical pollutants.
• Long-Term Maintenance: Occasional re-polishing or pressure washing for outdoor use.

Summary – Key Advantages

• High mechanical strength and durability
• Low water absorption and porosity
• Consistent fine-grain appearance
• Excellent for both indoor and outdoor use
• Widely available and cost-effective
• Available in multiple surface finishes for varied design applications
