Porphyry is a natural stone characterised by very fine-grained intrusions of phenocrysts.
Its colour generally varies from red to brown, purple and grey. Throughout history, one can see many monumental works realised with this material; today, however, its major use is in the building industry, both indoors and outdoors.
Porphyry allows the creation of non-slip surfaces, customisable formats and thicknesses, and is also a material that is very resistant even at low temperatures over time.
