Nero Marquina is a high quality marble, extracted in the Markina region of Northern Spain. It has fine and compact grain, black, with white veins. The reserves of this marble are high, which allows it to supply large interior projects.
Nero Marquina marble is considered an exotic one, different from common marbles. What differentiates an exotic marble from a common one is its geological formation.
Abrasive treatments with repeated applications result in a shiny surface, highlights the colour and properties of the natural stone.
A honed finish is identical to the polished finish, the surface is smooth but without glare or light reflections.
Blasting silica sand against the material through an air gun and generates very small craters.
Hitting the material, with a masonry tool called a bush hammer, that generates uniformly distributed craters of different sizes over the surface of natural stone.
Brushing the slab with a range of brushes and the result is a slightly undulating surface, very soft, warm and smooth to the touch.
Rough and irregular surface with small furrows and undulations in a mate tone.
Abrasive brushes under high pressure generate a touch-sensitive and smooth surface of natural stone.
Scratched finish is applied so that the surface exhibits a texture with straight reliefs and natural colours.
Splitting stone either by hand or by machine so that the surface exhibits a natural quarry texture.
