    Okay, now I'm really confused. I keep being told that propane burns
    hotter than butane--Peter just reiterated that. But, in the chart
    just posted by Randy: http://www.flamex.com/gasprop.htm the relative
    'values" are all over the place. I do see that, for  "total heating
    value after oxidation," propane is 19768 BTU/lb., and  butane is
    19494 BTU/lb., but, in every other measure, butane actually  seems
    considerably hotter than propane. Is "after oxidation" the only  one
    that counts?

the barricades in one "culture" and had at least taken physics and  
chemistry in high school...)
