Glossary, frequently asked questions on FMG marble, granite, travertine and stone slabs and tiles; cleaning and maintenance tips.
- Abrasion
- Wearing and grinding of a surface through friction. Erosion caused by the mechanical action of sea water on the rocks, cause and effect.
Cancellation obtained by scraping. Thanks to a mechanical movement, the surface abrasion of the manufactured slab originates honed marble and granite. - Abrasive
- Used to remove and cancel by means of friction. Abrasive substances are very hard and are used to hone, finish-off and polish surfaces. Abrasives are classified in natural abrasives: (grinder, corundum, silica and quartz) and artificial abrasives: (silicon carbon or carborundum, aluminium oxide, powder glass, steel and cast iron grains).
For more invasive roughing-off processes, coarse grain abrasives are used while increasingly finer grain abrasives are used for finishing-off and polishing processes.
