Basalt rocks are formed by the solidification of millions of years of volcanic magma, originating from lava flows, and are one of the most spectacular phenomena in nature.

Basalt is composed of small, even ultrafine particles even in its initial form. Sometimes, unusual cracks divide lava blocks into polygonal prismatic blocks, resembling pillars of artificial sculpture.

The main characteristics of basalt particles come from the properties of colored materials themselves. Basalt is a type of volcanic lava, which is a type of plagioclase. This mineral has high specific gravity, low porosity, and excellent UV resistance (rich in Mg, Fe, and Ca minerals).

Basalt is not corroded by acidic and alkaline aqueous solutions. Basalt particles are superhard, with high heat resistance and mechanical stress, making them the best raw material for making ceramic colored sand.
