Colored burn residue

  1. Jul 20, 2009 #1
    Hello. I am working on a project that employs the use of high voltage electricity to burn specific dielectric bodies: woods, plastics. My question is sort of unrelated to the goal of the project, but I was wondering if there was a way to burn a dielectric with high voltage so that the burn mark would not be black, but would be colored. Is there some sort of specific material to use, or a chemical process? I don't want the flame itself to be colored, I just want the remaining residue of the burn to be colored and permanent. Thanks.
