    About Hydrogen... 

    I wrote a feature article for AJM a few years ago called "torch
    song". It has a lot of detail on the gases and even electric methods
    to melt gold. I'm an advocate of hydrogen.  Been trained in most of
    the torch fuels including acetylene, propane, natural gas (methane)
    and my favorite is hydrogen by far.  Numerous shops have reduced
    solder pits just be switching to hydrogen for the torches. For torch
    casting it provides more than enough heat for silver, gold, and even
    platinum. Hydrogen is so light that a leak presents less of a threat
    than most others particularly acetylene or propane. 

    All the fuel gases contain enough energy to be lethal. None are as
    hot and clean as hydrogen.  There is no carbon in the gas unlike all
    the others. This means no carbon by products like carbon monoxide or
    dioxide.
