The stone NGI Azul Algarve is a blue/ grey colored limestone. It occasionally presents some darker and lighter areas.
Smoothing of the material in order to represent a smooth texture with slight reflection.
Polishing process of the material surface to ensure a shiny texture.
Exposure of the stone’s surface directly to a high temperature flame in which the end result is a fine and adherent roughness.
Creation of small craters, blasting silica sand against the material with an air gun, which highlight the color of the stone.
