Azulalia

Über Azulalia

Azulalia (also Azul de Évora, Cinzento Escuro Azulalia) is a Carboniferous granodiorite quarried in Vendinha, S.Vicente de Pigeiro, in the Évora district of the Alentejo region, Portugal. The stone is a fine-grained, largely non-directional intrusive rock with a composition of ~48% plagioclase, 25% quartz, 15% microcline, and 10% biotite mica — giving it a characteristic dark blue-grey coloration. DNSA (Stein 5004) provides comprehensive technical data: density 2685 kg/m³, compressive 139 MPa, flexural 35.7 MPa, water absorption 0.17%, abrasion 0.4 cm³/50cm² (Italian standard). Acid-resistant, frost-resistant with stable outdoor polish. Currently quarried but rarely imported to Germany per DNSA.
