Epidus Green Granite

Epidus Green Granite from Brazil is a medium- to coarse-grained natural stone characterized by a deep green to dark green base tone, often mixed with subtle grey and black mineral variations that create a naturally complex and slightly mottled appearance. Its visual effect is typically dense and uniform at first glance, but under closer inspection it reveals crystalline speckling and mineral flecks that give it depth and movement without strong directional veining. The texture is compact and crystalline, typical of granite, with interlocking quartz, feldspar, and mica minerals forming a hard, durable structure that polishes to a smooth, glossy surface while still retaining visible grain structure. According to typical Brazilian green granites of this type, it offers high density, low porosity, and strong compressive resistance, making it suitable for heavy-duty interior and exterior applications.

Visual Characteristics:

• Color: Deep green to dark green base with subtle grey and black mineral variations.
• Appearance: Dense and uniform at first glance with crystalline speckling and mineral flecks.
• Texture: Compact and crystalline with interlocking quartz, feldspar, and mica.
• Surface Finish: Polishes to a smooth, glossy surface while retaining visible grain structure.

Physical and Mechanical Properties

• Water Absorption:Typically low, often less than 0.35%, enhancing its durability against weathering.

• Density:High: Generally around 2.67 to 2.71 g/cm³, contributing to its durability.

• Flexural Strength:Ranges around 12 to 14 MPa, making it resistant to bending forces.

• Compressive Strength:Often exceeds 180 MPa, indicating its ability to withstand heavy loads.

• Hardness:Typically measures around 6 to 7 on the Mohs scale, providing excellent scratch resistance.

• Porosity:Low porosity contributes to its resistance against staining and moisture ingress.

• Slip Resistance:Varies with finish; a polished finish may be less slip-resistant, while honed or flamed finishes provide better grip.

Chemical and Mineral Composition (% by Weight)

• Quartz: Approximately 25-40%, contributing to its hardness and glossy finish.
• Feldspar: Around 35-60%, the primary component giving it a light reflectivity.
• Mica (Biotite or Muscovite): About 5-15%, adding to its visual complexity and slight shimmer.
• Accessory Minerals: Trace amounts of iron oxides and other minerals.

Usage and Applications

• Interior Applications:Flooring, countertops, backsplashes, stairs, and cladding due to its aesthetic appeal and durability.
• Exterior Applications:Facades, pavement, and landscaping elements because of its resistance to weathering and extreme conditions.

Maintenance

• Routine Cleaning:Use a mild detergent, soft cloth, and warm water. Avoid acidic or harsh chemicals.
• Sealing:Regular sealing recommended to maintain luster and prevent stains, particularly for countertops.

Cutting Sizes (cm)

• Standard Slabs: Typically 2 cm and 3 cm thickness.
• Custom Sizes: Available based on project requirement and quarry capabilities.

Common Surface Finish Options

• Polished:Glossy and smooth, enhancing the stone's natural color and pattern.

• Honed:Matte finish, providing a softer appearance and improved slip resistance.

• Flamed:Textured finish, suitable for outdoor use where slip resistance is critical.

• Brushed:Subtle texture with a slightly weathered look, offering a balance between polished and flamed.

• Leathered:Provides a soft sheen and tactile surface with enhanced slip resistance.

Epidus Green Granite’s unique visual depth and robust physical properties make it an excellent choice for both aesthetic and functional applications, ensuring longevity and timeless elegance in any architectural or design project.
