    There are apparently some newer methods of measuring flame temps
    that yield different results. I found that more recent data that puts
    propane at 5111 F and acetylene a 5678 F with oxygen as the oxidizer
    but there are a variety of numbers given by different sources so it
    is hard to be real definitive. 

    I am completely in agreement on some form of eye protection needs to
    be worn. Sunglasses are normally close to a shade 2 filter but not
    rated by ANSI.
