“Ghiara”, “la russa”, “agliara”, “agghiara”, “terra rossa”, are different namesby which this material is called. It’s a material with a sandy appearance, light pink to dark red in colour, produced by the firing of loose sediments by lava flows. Pozzolanic sand, was mixed with lime to obtain mortar used in construction.

Lava stone is not just ornamentation, beauty and art. It also becomes mystery and tradition. A magical ritual found among the memories of a grandmother from Nicolosi says "Heat lava stone in hot water. Then, wrapped in a cloth, rub it on the parts of the body that torment you either for physical or mental pain. It will remove all evil, curses and negativity from you."
