Vulcano Granite

Vulcano Granite is a breathtaking natural stone known for its deep black or dark brown base color, accentuated by striking veins and specks of rusty gold, white, and grey. Quarried in the Minas Gerais region of Brazil, it is a popular choice for various architectural and decorative applications due to its unique aesthetic and robust physical properties. Below are the detailed descriptions of its properties, composition, and uses.

Physical and Mechanical Properties:

• Water Absorption:Typically about 0.1% to 0.3%

• Density:Approximately 2,670 - 2,760 kg/m³

• Flexural Strength:Usually around 12 - 15 MPa

• Compressive Strength:Generally ranges between 180 - 210 MPa

• Hardness:6-7 on the Mohs scale

• Porosity:Low porosity, generally around 0.2% to 0.6%

• Slip Resistance:Dependent on finish. Polished surfaces are less slip-resistant compared to honed or flamed surfaces.

Chemical and Mineral Composition (% by weight):

• Quartz: ~30-40%
• Feldspar: ~40-50%
• Mica: ~5-10%
• Other Minerals (e.g., Biotite, Hornblende): ~5-10%
• Minor traces of iron oxides and other minerals contribute to the rusty gold accents.

Usage:

• Countertops:Ideal for kitchen and bathroom countertops due to its durability and resistance to scratches and heat.
• Flooring:Suitable for both residential and commercial flooring, though may need slip-resistant finishing for wet areas.
• Wall Cladding:Used for interior and exterior wall cladding, providing a luxurious aesthetic.
• Fireplaces:A popular choice for fireplace surrounds due to its heat resistance and striking appearance.
• Outdoor Applications:Suitable for outdoor kitchens, patios, and pool surrounds due to its weather resistance.

Maintenance:

• Regular Cleaning:Use mild soap and water for regular cleaning. Avoid acidic or abrasive cleaners.
• Sealing:Recommended to seal annually to maintain luster and prevent staining.
• Avoiding Damage:Use cutting boards and trivets to protect the surface from potential scratches and heat marks.

Cutting Sizes (cm):

• Slabs:Common slab sizes include 180-300 cm in length and 60-120 cm in width.
• Tiles:Typical tile sizes available are 30x30, 30x60, 60x60, and custom sizes upon request.

Surface Finish Options:

• Polished:Offers a shiny and reflective surface, enhancing the stone's natural colors.

• Honed:A satin-smooth surface which provides a more subdued finish compared to polished.

• Flamed:A rough texture created by high-temperature torching, suitable for slip resistance.

• Brushed:Provides a soft, textured finish that retains more of the stone's natural feel.

• Leathered:A smooth yet textured finish, offering a modern and rustic appearance.

Vulcano Granite is a versatile and durable stone, making it a popular choice for many high-end applications. Its striking color pattern and robust properties ensure that it performs well in a variety of settings while providing a touch of natural luxury.
