 The first record of work being done with marmorino is a building contract with the nuns of Santa Chiara of Murano in 1473.In this document, it is written that before the marmorino could be applied, the wall had to be prepared with a mortar made of lime and "coccio pesto" (ground terra cotta).This "coccio pesto" was then excavated from tailings of bricks or recycled from old roof tiles.
