She was also closely associated with the operas of Saverio Mercadante. Tadolini sang in the world premieres of his "Emma d'Antiochia", "Le due illustri rivali", and "Il bravo, ossia La veneziana" and in the premiere of the revised version of "Francesca Donato ossia Corinto distrutta", as well as in some of the earliest performances of his "Il giuramento" and "Orazi e Curiazi". Mercadante had also written the role of Lea in "La schiava saracena" expressly for her voice. However, the outbreak of the 1848 Revolution in Milan aborted the premiere and forced the temporary closure of La Scala. Another soprano, Carlotta Gruitz, sang the role in its official premiere later that year. Tadolini eventually sang Lea in 1850, for the premiere of the work's revised version at the Teatro San Carlo.
