Burn paintings are created through the process of burning images onto the canvas. Preparatory sketches are first drafted and are later drawn with pencil onto the raw canvas. Once the pencil drawing is on the canvas, a blow torch is used to carefully burn the contour lines and details of the image. Following the burning of these finer details, dark values are scorched with the blow torch onto the canvas. This process creates the under-burning, also known as the under-painting in traditional painting methods. With the under-burning complete, pigments are added to the canvas. The types of pigments used are crushed charcoal, India inks, crushed tempura and acrylic, all mixed with large amounts of water. Finally, after all the pigments have been added, a torch is again used to give the painting a burnt finish.
