or spolvero. Sheet of paper or cartoon in which small holes are pricked along the outline of a drawing in order to transfer the drawing on a 1:1 scale onto a new surface, by swinging a bag of graphite powder or a coloured pigment towards the pricked holes of the drawing. The impression of the original is, in this way, transferred to the new surface, thanks to the passage of the powder or the pigment through the holes. Cennino Cennini (end of the 14th century) speaks of the pouncing technique in relation to panel painting, while Filippo Baldinucci (1681) defines the term spolvero as: "made with pouncing techniques, that is a sheet of paper pricked with holes, through which the design is obtained, by allowing the gesso or graphite powder tied up in a pouch to pass though the holes, which is called pouncing."
