    It depends on what you're going to do.  I made my first complex gold
    chain, doing all the soldering with a bunsen burner and a blowpipe. 
    I wrapped a very thin piece of tubing around the base of the burner
    and aimed the end across the top, then put a piece of surgical tubing
    on the other end of it, and the flame was plenty hot enough to not
    only solder, but melt the occasional piece when I got carried away. 

    You need good lungs.  ;-)
