What will happen? If I took a very small amount of pure acetone, put it in a bowl and went outside to set it on fire(safety first). I am curious because I am a hiker and I am working on a lightweight alcohol stove. I don't have any alcohol that seems to work right now but I do have acetone and I was wondering if it could be used as an alternative. I hope this doesn't sound too stupid but it seems to me that since they are both flammable liquids and denatured alcohol has acetone in it it might be ok to try. Also is it possible for me to mix say, 50% alcohol(rubbing) and X quantity of acetone in an attempt to get the fuel to burn better? Any info would be very helpful. Thanks.
