Gold Star Granite

Gold Star Granite is a visually appealing and functional natural stone renowned for its warm golden-yellow hues complemented by beige tones and scattered black and brown mineral specks. This combination gives the granite a consistent, slightly mottled “golden sand” appearance which is both simple and elegant. Quarried in Brazil, it features a medium-grained crystalline texture and structure, primarily composed of quartz, feldspar, and mica. Its dense interlocking structure offers remarkable durability, while a lightly sparkling polished finish provides an eye-catching luster.

Physical and Mechanical Properties:

• Water Absorption: Typically ranges from 0.28% to 0.35%. This indicates low porosity, making it resistant to water infiltration and staining when properly sealed.

• Density: Approximately 2,690 to 2,740 kg/m³. This high density contributes to its durability and robustness.

• Flexural Strength: Generally around 12 to 15 MPa. This measures the stone's ability to withstand bending or curving forces.

• Compressive Strength: Typically between 178 to 188 MPa. This assesses the stone's capacity to resist being crushed under pressure.

• Hardness: Rated 6 to 7 on the Mohs scale, indicative of its high scratch and abrasion resistance.

• Porosity: Low porosity, contributing to its resistance to water and staining, especially when treated with a good quality sealant.

• Slip Resistance: Depending on the finish, it can vary. Polished surfaces are generally more slippery when wet, while honed or flamed textures provide better grip.

Chemical and Mineral Compositions (% by weight):

• Quartz: 20-30%
• Feldspar (Alkali Feldspar and Plagioclase): 50-60%
• Mica (Biotite and Muscovite): 5-15%
• Other Minerals (e.g., Orthoclase, Tourmaline, Garnet): 5-10%

Usage:

• Countertops: Its durability and aesthetic appeal make it ideal for kitchen and bathroom countertops.
• Flooring: Suitable for both residential and commercial spaces, providing elegance and durability.
• Wall Cladding: Offers a sophisticated appearance for interior and exterior walls.
• Fireplaces and Mantels: Enhances the warmth and style of living spaces.
• Tabletops: Perfect for dining and coffee tables, offering both functionality and beauty.

Maintenance:

• Cleaning: Use mild soap and water or granite-specific cleaners; avoid harsh chemicals.
• Sealing: Regular sealing is recommended to protect against staining and maintain appearance.
• Polishing: Occasional polishing can enhance the surface’s shine and luster.

Cutting Sizes (cm):

• Slabs: Typically available in 2 cm and 3 cm thicknesses.
• Tiles: Commonly manufactured in sizes like 30x30, 30x60, and 60x60 cm.

Available Common Surface Finish Options:

• Polished: Provides a reflective, glossy surface that highlights the granite's natural beauty.
• Honed: Offers a matte finish for a more subdued, elegant look.
• Flamed: Produces a textured surface with improved slip resistance, ideal for outdoor applications.
• Brushed/Leathered: Creates a soft sheen with a slightly textured and tactile surface.

Gold Star Granite, with its stunning appearance and robust properties, is a versatile choice for a variety of architectural and design applications.
