Sorcery is a common mystical art practiced by many people who study magic. From what is told in the books, it is only limited by your imagination and the strength of your aura. This most likely means that you can do almost anything wth sorcery, as long as you can imagine it. It is also stated to be a very powerful art in the hands of a master, such as Perenelle Flamel since it was stated by Macchiavelli that his aura was probably going to combust in his battle with her, while hers, it seemed, could've gone further. The battle, however was cut short by the energies they released causing Mt. Etna to erupt.
