Nero Vitoria Granite

Nero Vitoria Granite is a captivating natural stone quarried in Brazil, characterized by its dark grey to nearly black background that is beautifully enhanced with fine and medium specks of white, grey, and occasionally silver minerals, resulting in a refined salt-and-pepper effect. Its uniform and elegant appearance, particularly when polished, makes it an excellent choice for various architectural applications due to its mechanical strength, durability, and aesthetic appeal.

Physical and Mechanical Properties:

• Water Absorption:Typically less than 0.35%, indicating low porosity and making it resistant to staining.

• Density:Generally around 2,690 to 2,740 kg/m³, contributing to its robustness and durability.

• Flexural Strength:Typically ranges from 11 to 14 MPa, depending on the specific cut and finish, which signifies good ability to withstand bending forces.

• Compressive Strength:Often falls in the range of 160 to 210 MPa, indicating high resistance to crushing forces.

• Hardness:Scores around 6 to 7 on the Mohs scale, showing resistance to scratching and wear.

• Porosity:Very low, generally under 1%, enhancing its resistance to moisture and staining.

• Slip Resistance:Varies with finish: polished finishes have lower slip resistance compared to honed or flamed / brushed finishes which are more suitable for wet areas.

Chemical and Mineral Composition (% by weight):

• Quartz:Typically around 20-30%, contributing to hardness and shine.

• Feldspar:Comprises about 60-70%, providing strength and contributing to the dense crystalline structure.

• Biotite:Generally ranges from 5-10%, introducing darker mineral flecks.

Usage Recommendations:

• Interior Applications:Ideal for kitchen countertops, bathroom vanities, flooring, and backsplashes due to its refined elegance and toughness.

• Exterior Applications:Suitable for cladding, paving, and outdoor countertops owing to its weather-resistant properties.

Maintenance:Requires regular sealing to maintain its low porosity and to protect against stains. Normal cleaning with mild, non-abrasive soaps and water is recommended.

Surface Finish Options:

• Polished: For a glossy, reflective surface that highlights the stone's crystalline structure.
• Honed: Offers a smooth, matte finish ideal for floors.
• Flamed: Provides a rough texture suitable for slip resistance in outdoor spaces.
• Brushed: Slightly textured finish offering a softer look while maintaining durability.

General Care Tips:

• Avoid harsh cleaners that can dull the shine.
• Use coasters and trivets to protect against potential etching or thermal shock.
• Regular inspections and resealing can prolong the life and appearance of the granite.

Nero Vitoria Granite serves as a versatile and aesthetically pleasing material for both functional and decorative elements in various construction and design projects, offering durability and style with the reassurance of longevity.
