Bushhammering This process gives marble a rustic look and enhances its texture, while at the same time smoothing over any variation and unevenness, and making the material slip-proof. The bushhammered effect is created with a hammer provided with pyramidal tips. The final bushhammered surface can be coarse or fine-grained, with all intermediate grades of finish. |

Flashing Flashing is a thermal process that uses oxygen and gas (propane or equivalent gas) to create a high-temperature flame (2500-3000°C) which is blown against the surfaces to be treated, which undergo a thermal shock at about 600°C. This treatment, combined with immediate water-cooling of the surface, generates an expansion effect and a consequent thermal cracking of the quartz or silica. The surface will have a rough, raised texture, thus enhancing the structure and colour of the material. Since this vitrification process increases resistance to atmospheric agents and erosion, flashing is particularly suited for external linings, but must be used judiciously, and only on marble types that can withstand large temperature fluctuations. |

Dotting Dotting is a manual process that involves hammering a stone surface with a pointed tool. The result is a very evident raised effect and a contrasting chromatic appearance. |
|
Brushing Brushing uses specific abrasive brushes mounted on the polishing line. The process gives an orange-peel effect with a slightly corrugated texture yielding a "silky effect". |
|
Ribbing Ribbing is characterized by a succession of adjacent grooves, made by means of diamond wheels or a large range of tools with different profiles. The final result, which is highlighted on all the materials, is accentuated by side light or light from a low angle, which, striking the corrugated surface, "animates" it with chiaroscuro effects. |
