I set me canvas on fire to achieve a ground and the desired texture/affect. After I set the canvas on fire I leave it to cool. Once it is somewhat cooled I then paint further into it with pain and fire if needed. I paint what I see around me, landsacpes, seascapes, landscapes of my mind, I suffer from chronic back pain and sometimes channel that pain into my art where I have created some very brillaint abstract pieces. I have been doing this technique for 15 years now and every painting I do I learn more about it and how to manipulate fire. Fire is fire and has a mind of its own so one must be careful.
