What is "nenfro"

Nenfro is a volcanic rock, gray tuff, little resistant compact structure, typical of the Viterbo region that the Etruscans used in their sculptures of northern Lazio:

• The Winged lion of Vulci, in the Louvre
• The Centaur of Vulci, preserved in the Villa Giulia in Rome
• The sarcophagus of Laris Pulena MS 3488 of Civita Musarna.
• The sarcophagi figured at the galleries and the entrance to the Tarquinia National Museum

One of its features is to take a pinkish tint when drying.
