Black Galaxy Granite

Black Galaxy Granite is a popular natural stone that is quarried in the southern part of India, primarily in the state of Andhra Pradesh. It is also known as Star Galaxy Granite due to the presence of small, reflective metallic flecks that resemble stars against a black background.

This granite has a dense and durable composition, making it suitable for a variety of interior and exterior applications. It is commonly used for flooring, countertops, wall cladding, and monuments.

This Granite has a uniform, deep black color with small, golden and copper-colored flecks scattered throughout. The flecks are primarily composed of a mineral called pyrite, which gives the stone its unique appearance. The flecks can vary in size and density, with some slabs having more or less of them than others.

The finish of this Granite can vary from polished to honed, flamed or leathered, giving it different textures and appearances. It has a high resistance to staining, scratching, and heat, making it a popular choice for kitchen countertops and other high-traffic areas.

Overall, Black Galaxy Granite is a beautiful and versatile natural stone that adds a touch of elegance and sophistication to any space it is used in.

1. Origin: It is exclusively quarried in the Chimakurthy area of Andhra Pradesh, India. This region is known for its abundant deposits of high-quality granite.
2. Durability: As a natural stone, it is highly durable and can withstand heavy use and foot traffic. It is also resistant to weathering, making it a suitable choice for outdoor applications such as paving and landscaping.
3. Availability: It is readily available in different sizes, thicknesses, and finishes. It is also relatively affordable compared to other exotic natural stones.
4. Maintenance: To maintain the shine and luster of it, it should be sealed periodically to prevent staining and etching. Regular cleaning with a neutral pH cleaner is also recommended.
5. Design flexibility: The unique speckled pattern of this Granite makes it a versatile stone that can be used in a range of design styles, from traditional to modern. It also pairs well with other materials such as glass, stainless steel, and wood.
6. Sustainability: The granite industry in India is regulated by the government, and measures are taken to ensure that the quarrying and processing of natural stone are carried out in an environmentally responsible manner.

Technical Specifications for Black Galaxy Granite :

1. Composition: It is primarily composed of feldspar, quartz, and mica, with small amounts of other minerals such as pyrite and hornblende.
2. Density: Its density is approximately 2,930 kg/m3, which is considered to be a high density for a natural stone.
3. Water absorption: The water absorption rate of it is relatively low, typically ranging from 0.05% to 0.15%. This makes it highly resistant to water damage and staining.
4. Compressive strength: The compressive strength of it is around 200-300 MPa, which makes it a very strong and durable material.
5. Flexural strength: The flexural strength of it is around 20-30 MPa, which means it is able to withstand bending and twisting forces without breaking.
6. Hardness: It has a hardness rating of 6-7 on the Mohs scale, which is considered to be a relatively hard material. This means it is resistant to scratching and abrasion.
7. Slip resistance: The slip resistance of it varies depending on the finish. Polished and honed finishes can be slippery when wet, while textured finishes such as flamed or leathered are more slip-resistant.

These technical specifications make Black Galaxy Granite a highly desirable material for a range of applications, including flooring, countertops, wall cladding, and exterior paving.
