Pouncing
A method of transferring a drawing or design to another surface such as canvas, panel or fresco, by dabbing pounce (fine powder of charcoal or chalk) through pinpricks marking the outlines of the drawing. The design is therefore reproduced on the surface below as a series of dots (see also cartoon).
