Technical details

  • Water absorption
    This is how much water the rock can "suck in" when it comes into contact with liquids. More porous stones tend to absorb more water, while others hardly absorb any at all. This is important when choosing materials for wet areas, such as kitchen worktops.

  • Apparent porosity
    This is how much "empty space" a rock has inside it. Imagine a sponge: it has lots of little holes through which air and water pass. Some rocks also have small pores that can absorb liquids or air, but on a much smaller scale than a sponge

  • Abrasion resistance
    This is the rock's ability to withstand the wear and tear caused by daily use. Think of a shopping center floor, for example, which receives thousands of steps every day. If the stone is very resistant to abrasion, it will remain intact for a long time. If it is m

Azul Macaubas

Extremely compact quartzite with blue mineral inclusions. Different concentrations of dumortierite impact the undulating structure and make Azul Macaúbas one of the most beautiful rocks in the world. The color spectrum ranges from bluish-white to rich sky blue. However, several shades are almost always present in one block. The yellow to brown veins and inclusions originate from iron oxides. Almost every slab can be seen as unique due to the strong color variation.

  • Hardness
    The higher the hardness of a rock, the more resistant it will be to scratches, that is, its resistance to abrasion. The closer to 10, the more resistant it will be to abrasion. The hardness used in Rock Library is from the Mohs Scale.

  • Reacts with acids
    The reaction with acids happens when a solution with acidic pH comes into contact with the rock, which releases a corrosion on the surface, removing part of the shine.
