Porphyry is a volcanic rock, whose formation in the Trentino Alto Adige Region traces back to the so-called "Lower Permian". From the geological and mining point of view, the porphyry stone is the effusive correspondent of granite. This volcanic rock belongs to the "Atesina Porphyry Platform", which is the result of an intense volcanic activity began 260 millions of years ago.
The technical characteristics of this material (high compression breaking point, high resistance to chemical agents, high resistance to sudden changes in temperature) make porphyry one of the hardest and most resistant stones quarried in Europe.
Thanks to its gifts of versatility and easiness in working, the porphyry stone is employed with great success in the paving and facing both for outdoors and indoors, with optimal architectural results. With porphyry are paved the most important European squares and a lot of areas around the world.
A vast range of articles is available both raw and carved, in a lot of forms and measures and with many grades of finish.
Everything the building trade needs can be realized with porphyry stone.
