Unburned butane does have a taste, it is hard to explain it, but I have directly inhaled it straight from the refill can and it had no effect at all.
Synthesizer Man Reviewed by Synthesizer Man on . The Butane Taste Lie The Butane Taste Lie Butane is this molecule C4H10 four carbons, ten hydrogens. Let's take a look at the flame produced by burning this molecule. First the hottest part of the flame is the blue at the base (temperature is proportional to the frequency of light). Blue light has a higher frequency (shorter wavelength) than red light. The blue is caused by the burning (oxidizing) of the hydrogen. These guys love to get together and make water (H2O), thatâ??s why we have so Rating: 5
