River Black Granite is a popular natural stone that is quarried in the Southern part of India, particularly in the state of Karnataka. It is a dense, hard, and durable material that has a consistent dark black background with small to medium-sized flecks of white, gray, and silver minerals that are evenly spread throughout the surface.
This granite has a polished finish, which gives it a lustrous shine that enhances its natural beauty. Its high resistance to abrasion, staining, and scratching makes it a popular choice for a wide range of applications, including kitchen countertops, flooring, wall cladding, and outdoor paving.
It is also known for its versatility in design, as it can be used in both modern and traditional settings, and it pairs well with a wide range of colors and materials. Its rich and elegant appearance makes it a sought-after choice for high-end residential and commercial projects.
- Physical Properties: It is a fine-grained igneous rock that belongs to the family of black granites. It has a density of around 2,800 kg/m³ and a compressive strength of 210 MPa. It has a low water absorption rate of 0.15% to 0.20%, which makes it highly resistant to water damage.
- Color and Texture: The color of River Black Granite is mostly black with varying shades of white, gray, and silver minerals that are evenly distributed throughout the surface. The size of the mineral flecks can range from small to medium-sized. The texture of the stone is generally uniform and fine-grained, giving it a smooth surface finish.
- Applications: River Black Granite is a popular choice for kitchen countertops, bathroom vanities, flooring, wall cladding, staircases, and outdoor paving. It is also used for decorative purposes such as monuments, memorials, and sculptures.
- Maintenance: It is a durable and low-maintenance material. It can be easily cleaned with a mild soap solution and warm water. Regular sealing can help to prevent stains and ensure the longevity of the stone.
- Availability: It is widely available in the Southern part of India, particularly in the state of Karnataka. It is exported to various parts of the world, including the United States, Canada, Europe, and the Middle East.
