I call these Elemental Inks because I try to incorporate multiple elements into my creative process. The ink is made with soot from fire. I drip water and let it carry the ink where it will. I use my breath to blow the ink around the paper.
I use India Ink, Calligraphy Ink, or sometimes even a good old Sharpie. I often use wood pieces to draw the ink, rather than pens or brushes.
Prints for most and originals for some are available, contact me if you are interested.
