Description

Maori Granite is a visually striking natural stone quarried in Brazil. Its dramatic and stark black background is interspersed with large, wavy veins of gray and white, creating a bold and elegant appearance. This granite is popular for its aesthetic appeal and robust physical and mechanical properties, making it suitable for various applications in architecture and design.

Physical and Mechanical Properties:

  • Water Absorption:Typically ranges from 0.15% to 0.45%. Indicates low porosity, meaning it is resistant to infiltration by liquids.
  • Density:Approximately 2.68 to 2.72 g/cm³. Denotes a relatively high density, contributing to its durability and strength.
  • Flexural Strength:Generally around 13 to 17 MPa. Suggests good resistance to bending and surface pressure.
  • Compressive Strength:Typically between 165 to 185 MPa. Implies excellent load-bearing capacity, suitable for heavy-duty applications.
  • Hardness:Rated between 6 and 7 on the Mohs scale. Indicates a high level of scratch resistance.
  • Porosity:Very low; contributes to the material’s stain resistance and durability.
  • Slip Resistance:Dependent on surface finish; honed and textured finishes usually offer better slip resistance compared to polished surfaces.

Chemical and Mineral Compositions (% by weight):

  • Quartz:20-30%. Provides hardness and scratch resistance.
  • Feldspar:40-50%. Contributes to color variations and overall durability.
  • Biotite and/or Hornblende:10-15%. Adds to the granite’s dark background and contributes to strength.
  • Mica:5-10%. Offers subtle luster and slight color variation.
  • Other Minerals (e.g., iron oxides, magnetite):5-10%. May influence the stone's overall color and pattern.

Usage:

Interior Applications:

  • Kitchen countertops

  • Bathroom vanities

  • Fireplace surrounds

  • Floor tiles

Exterior Applications:

  • Facade cladding

  • Outdoor kitchen surfaces

  • Pavers and garden accents

Maintenance:

  • Regular sealing recommended to maintain stain and scratch resistance.
  • Clean with pH-neutral cleaners to preserve the surface finish.
  • Avoid harsh chemicals and abrasive cleansers.

Cutting Sizes (cm):

  • Commonly available in slabs of varying thicknesses (2 cm and 3 cm).
  • Custom sizes typically range from 60 cm x 60 cm to large slabs depending on quarry capacity and client specifications.

Surface Finish Options:

Polished:

  • High gloss, enhances color and pattern.
  • Suitable for interior surfaces prone to less wear and tear.

Honed:

  • Satin-smooth with little to no shine.
  • Ideal for high-traffic areas, provides better slip resistance.

Leathered:

  • Textured with a soft sheen.
  • Popular for countertops and surfaces where a tactile finish is desired.

Bush-hammered or Flamed:

  • Rough texture for high slip resistance.
  • Typically used for outdoor flooring and cladding.

Maori Granite's distinct composition and appearance make it a versatile choice for both aesthetic and functional applications, providing both beauty and resilience.

FAQ

Can Brazil's Maori Granite be used exterior applications in cold climates?

Brazils Maori Granite can generally be used for exterior applications in cold climates. Granite is known for its durability and resistance to extreme temperatures, making it suitable for outdoor use in various climates, including cold regions. However, its important to consider a few factors when using Maori Granite or any granite in cold climates: 1. Water absorption: Granite is porous to some extent, and if water gets absorbed into the stone and then freezes, it can cause cracking or damage over time. To prevent this, its essential to choose a granite with a low water absorption rate and ensure proper sealing of the stone. 2. Frost resistance: Maori Granite is known for its frost resistance, which means it can resist freeze-thaw cycles without significant damage. This property is crucial in cold climates where water can freeze and expand in the stones pores, leading to cracking or deterioration. 3. Maintenance: Regular maintenance, such as sealing the granite and keeping it clean, is essential in cold climates. This helps prevent water infiltration and minimizes the chances of any freeze-thaw damage. By considering these factors and ensuring proper installation and maintenance, Brazils Maori Granite can be successfully used for exterior applications in cold climates.
