Forensic people use black powder to get fingerprints of surfaces that need to be collected. The powder is made of "black carbon or charcoal." Its easy to make a mess with it since it comes out very fast. It's easier to use along with other tools to collect those hard to see fingerprints.
The words black carbon or charcoal came from this website http://www.bxscience.edu/publications/forensics/articles/fingerprinting/f-fing03.htm

My opinion of Forensic Black Powder is interesting, I never knew they would use this to collect fingerprints I thought they used just the special tape.
