Mined from the Albiano quarry, granted in concession to the Alliance of Stone group of which Euro Porfidi is a part, Mixed Grey Porphyry is a grey / brown material that comes from Trentino easy to match with Trentino split porphyry. Like most porphyry, it maintains its physical-mechanical features unaltered over time. It's resistant to ice, temperature changes, and acids, and therefore suitable for both exterior and interior applications and also coverings, kitchen tops, and furnishings.
