Tunas Green Granite

Tunas Green Granite is a durable and versatile natural stone, quarried in Barro Vermelho, Tunas do Paraná, in the state of Paraná, Brazil. This granite is primarily dark creamy green and gray, adorned with distinctive flecks of darker gray and black, making it an appealing choice for various architectural and design purposes.

Physical and Mechanical Properties:

• Water Absorption: 0.29%
• Density: 2664 kg/m³
• Flexural Strength: 17.96 MPa
• Compressive Strength: 151.00 MPa
• Hardness: Typically measured on the Mohs scale, granite generally ranges from 6 to 7, indicating its ability to resist scratching and abrasion.
• Porosity: Granite generally has low porosity, which helps reduce absorption and increases its durability.
• Slip Resistance: Varies based on surface finish, but generally offers good resistance when properly finished, such as with a honed or flamed surface.

Chemical and Mineral Compositions (% by weight):

• Quartz: Predominantly found in granite, contributing to its hardness and durability.
• Feldspar: A significant portion, including both plagioclase and potassium feldspar, which contributes to the granite's color and strength.
• Mica: Including biotite and muscovite, which provides the darker flecks.
• Other minerals and oxides: Including but not limited to amphiboles and trace minerals, contributing to its aesthetic and some physical properties.

Usage:

• Interior Applications: Kitchen countertops, bathroom vanities, flooring, wall cladding, and staircases.
• Exterior Applications: Facades, pavers, and outdoor kitchen surfaces.
• Decorative Uses: Suitable for monuments, sculptures, and other artistic applications due to its unique color and pattern.

Maintenance:

• Sealing: Regularly seal to enhance stain resistance.
• Cleaning: Use a neutral pH cleaner, avoiding acidic or abrasive substances.
• Polishing: Periodically polish surfaces to maintain luster, especially for interior applications.

Cutting Sizes (cm):

• Standard Slab Sizes: Typically available in slabs of 2 cm and 3 cm thickness.
• Custom Sizes: Can be cut to custom dimensions based on project requirements.

Available Common Surface Finish Options:

• Polished: High gloss finish that enhances the stone’s color and pattern.
• Honed: A smooth, matte finish that reduces glare and enhances slip resistance.
• Flamed: A rougher, more textured surface ideal for external applications where slip resistance is critical.
• Brushed: Offers a slightly textured finish that retains some of the natural stone feel.

Tunas Green Granite is appreciated for its aesthetic qualities and rugged durability, making it a popular choice in both residential and commercial projects. Its versatile nature allows it to be tailored to various finishes and applications, making it a timeless addition to any design. Regular care and appropriate sealing can greatly extend its longevity, keeping installations beautiful and functional for many years.
