The single-firing process (as opposed to Bicottura which fires twice or more times) of making tile from terra cotta clay and firing it high enough to achieve a strong and dense product. Normally and engobe layer is applied over the body and glaze over that. The technique requires considerable expertise to develop a strong fired product (by virtue of crystal development in the matrix) and deal with the physical and thermal expansion matching of engobe and glaze to the body (and each other).
