Finishes
Leather
Surface treated from the sawn material. It consists of passing the slabs through a brushing process using diamond bristles with which a rough and smooth surface is achieved.
Aged
Treated surface equal to flamed and subsequently going through a brushing process, giving a rough and smooth result.
Polished
Completely smooth and shiny finish achieved by abrading the surface of the material and applying waxes. This is the most requested finish for countertops, because of its ease of cleaning and disinfection. By closing the pores, greater resistance to external agents is obtained.
Applications
As its name suggests, it comes from the African continent and, like all blacks, is widely used in interior decoration or funerary art.
