I hope I can get some help here, I am looking for a layman's explanation of the difference between Layman's difference between KMnO4 & KFO2N. I ask because in last year's seasons of several survival tv shows, they showed them starting fires via a chemical reaction between Glycerin and Potassium Permanganate. I did some research, and Potassium Permanganate is sold as a fish pond chemical. Here is where it gets interesting. If you do a Google search on Potassium Permanganate, you see chemical supply houses selling KMnO4, and you see pool supply stores selling it under the name "pot-perm", but in small print you may be getting either KMnO4 or KFO2N. Which is the one they likely used on the tv shows to start fires?
