1) Tufo Grigio di Nocera: produced by the eruption of Ignimbrite Campana (Campi Flegrei – 40,000 years ago) and present in the quarries of the territory of Nocera. Due to its lightness, workability and resistance, it is used for architectural works of great importance; a valuable example is the portal of the Zurlo Chapel in Boscoreale.
2) Grey Tuff of Sorrento: produced by the eruption of the Ignimbrite Campana, present in the quarries of the Sorrento territory and clearly visible along the cliff of Sorrento. Due to its lightness and resistance, it is used for the construction of load-bearing walls.
3) Yellow Neapolitan Tuff: produced by the eruption of the same name (Campi Flegrei – 15,000 years ago) and present in the quarries of the city of Naples and in the hills to the north. Because of its easy workability, strength and lightness, it is used for the construction of load-bearing walls.
4) “Scardoni” of lava stone: produced by the effusive eruptions of Vesuvius in the last 2000 years and present in the numerous quarries of the Vesuvian area; they were used with a mixture of mortar for the construction of foundations and masonry of buildings.
5) “Lava foam”: very vesicular lava (remains of gas bubbles present inside the lava flows). It characterizes the most superficial and exposed parts of the lava flows; the presence of voids, the vesicles, gave this rock a remarkable lightness that made it useful in the construction of vaults and arches.
6) Piperno worked in steps: very compact tuff with the typical structure of flames, formed by the deposition of pyroclastic flows of the eruption of Ignimbrite Campana (Campi Flegrei – 40,000 years ago); The piperno was used for the construction of architectural works of great value (Offered by Maestro Luigi Minichino).
7) Lava stone worked by steps: produced by the effusive eruptions of the Sum-Vesuvius of various ages, it was worked for steps of stairs, thresholds of doors and windows, balconies, arches and portals.
8) Lava stone worked for furniture: produced by the effusive eruptions of the Sum-Vesuvius of various ages, was worked by “stonemasons” for fireplaces, benches, tables, and other works of finishing of buildings. (Work of Master Carmine d’Errico).
9) Lava stone cubes for flooring: produced by the effusive eruptions of the Sum-Vesuvius of various ages, it was worked for the flooring of roads, sidewalks and courtyards.
10) “Basle” of lava stone for road paving: produced by the effusive eruptions of the Somma-Vesuvio of various ages; it was worked for the paving of roads, sidewalks and courtyards.
