Absolute black is a fine-grained, dense, and homogeneous natural stone characterized by its complete absence of color and pattern. It is also known as black granite although it is technically not a true granite. Here are some of its physical properties:

1. Color: Absolute black has a deep, pure black color. It does not contain any veining, specks, or other color variations typically found in other stones.

2. Hardness: It is a very hard and durable stone with a Mohs hardness rating of around 5.5 to 6.5. This makes it highly resistant to scratches, cracks, and chips.

3. Density: It has a high density, ranging from about 2,680 to 2,970 kilograms per cubic meter. This density contributes to the stones durability and strength.

4. Porosity: Absolute black is a low-porosity stone, which means it has a very low water absorption rate. This makes it resistant to liquid stains and easy to clean.

5. Luster: It exhibits a high degree of luster when polished, giving it a glossy shine. This enhances its elegant and luxurious appearance.

6. Heat Resistance: Absolute black is known for its excellent heat resistance. It can withstand high temperatures and is commonly used for kitchen countertops where hot pots and pans are placed.

7. Durability: It is a dense and tough stone that is resistant to wear and tear. It can withstand heavy foot traffic, making it suitable for application in both interior and exterior spaces.

8. Availability: Absolute black is quarried in various parts of the world, including India, Angola, China, and Zimbabwe. The specific quarry location can slightly impact the stones exact physical properties.

Overall, absolute blacks physical properties make it a sought-after material for various applications, including countertops, flooring, wall cladding, and monuments, due to its timeless and stylish appearance.
