Painting with Unusual Substances

Steve Spazuk paints with fire, using the soot to create beautiful art.

I just came across this post about artists who paint "with everything (but paint)", and wanted to share it with you! The original post is in German, but you can read the Google translated version here. I particularly like the fire and blood ones - there's just something so esoteric about them. (The coffee, sugar, and wine ones are also wonderful, though!)
