The stone NRV Relvinha is a light beige limestone, with thin grain and soft veins. In terms of hardness it is considered a soft natural stone. The main variations have more or less veins.
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.
Formation of small smooth and wavy reliefs on the surface of the stone through the execution of brushes under high pressure.
Creation of small craters, blasting silica sand against the material with an air gun, which highlight the color of the stone.
Application of an hammer called “Bujão” in the material to generate craters, randomly distributed on its surface.
Process of breaking the stone manually, in which the end result will be an irregular, chipped and natural texture.
