  Note that resistance to high-temperature does not neccessarily imply
resistance to fire.  Also the wicks of a torch do not get all that hot
because the flame reaction is happening some distance from the wick.  
Also fuel is evaporating off the wick, cooling it.  (If you've ever
caught a torch by the flaming wick you probably didn't get burned unless
you touched a screw or held on too long.)
  Once I used 30% water 70% ethanol as a fuel.  It burned but the wick
was cold and wet if you touched it.
  The wick temperature only rises as the fuel is running low.  This is why
you're advised to blow torches out before they burn out -- it prevents the
wick from heating up and degrading.
  What I would like to know is how does one control the temperature of
the actual flame?  Pyrotechnicians have great knowledge of how to control
reaction temperatures in fireworks -- but these are solid state reactions.
A pyro I've corresponded with claims adding water to the fuel (I'm talking
about alcohol here) would have little effect on the flame temp because
the specific heat of gaseous water is not significantly different from
that of air.
