The acid etching marble is a chemical marble finish that aims to give the marble a worn look, close to that obtained by brushing but more aged. This marble finish makes the surface of the stone irregular and characterized by soft hollows. The chemical corrosion used to give life to the etched marble creates a slab where the color and marble surface texture of the underlying matrix are clearly highlighted. The rough and worn appearance of etched marble makes it an excellent choice for the creation of internal and, especially, external flooring.
Let’s now see in detail how an etched marble slab is produced. First of all, it should be said that marble etching is a delicate procedure which cannot be carried out on site but must necessarily be completed in the factory. The main reason, beyond the danger of the acids that are used, is that the slab to be treated must be immersed in special tanks containing these highly corrosive chemicals which react with the porosity of the stone. As previously described, the final result of this stone finish is a slab with an irregular surface whose recesses are more or less excavated according to the degree of marble etching chosen.
Etched marble finish is obviously more effective on soft stones than on harder types. In the case of etched granite, this marble finish is used only to clean the stone and therefore have a cleaner slab.
Very often acid etching marble is preceded by other marble stone finishes such as bush hammering or sandblasting with the intent of increasing the worn effect.
Finally, we remind you that the processing of acid etched marble is part of one of the marble treatment techniques used for the so-called antiquing finish together with other marble stone finishes such as tumbling, brushing and sandblasting.
Luxurious furniture in lightweight marble
Dedalo is a company from Carrara that designs and produce monolithic luxurious furnishings in lightened marble, with a contemporary design. Our goal is to reaffirm the use of marble in everyday life without renouncing, for reasons of weight, to its three-dimensional vocation, proposing sculptural and extremely engaging shapes.
